Target drives for specific groups - Logical Disk Monitoring

I want to target different drives and thresholds for logical disk monitoring. I want to be able to place the server in a group and monitor the drives accordingly. Can this be done? How would you go about doing it?

couple of ways you can go about this:
1. Place the servers into a group and apply the necessary overrides to the logical disk monitors
2. If you don't want the same threshold applied to all the drives on the same server create a new group and add the specific drives to the group and then apply the necessary overrides to the group for logical disk monitors.
3. If you don't want the same threshold applied to all the drives you could also create a dynamic group ie all D: for servers and then apply the overrides to that group.
example of this see: https://social.technet.microsoft.com/Forums/systemcenter/en-US/c2719fb1-9298-435a-8bf9-3c92d4b34f85/making-groups-of-logical-disk?forum=operationsmanagergeneral

Windows Server 2008 R2 Logical Disk monitor is not listed in SCOM 2012

Dear Experts,
I tried to create an override of Logical Disk space threshold value changes on one of Windows 2008 R2 OS, But unable to find the respective monitor of 'Windows Server 2008 R2 Logical Disk' monitor in the scope, But I can see Windows Server 2008 Logical
Disk monitor is there and if I do right-click create override the monitor for particular specific of Windows server 2008 computers then the Windows 2008 R2 computer is not displaying there. Finally I found Windows Server 2008 R2 Logical Disk monitor is
missing ?
Can you please help me to achieve this ?

Custom Logical Disk monitor incorrectly flapping between healthy and unhealthy

One of the clients Ops Mgr 2012 SP1 UR8 environments I am supporting has had some custom logical disk monitoring setup; there are 5 groups dynamically populated by logical drives depending on their size (1st group has small drives up to the last group with
very large drives). There is a 'Warning' and 'Critical' Monitor setup per server OS version, the Monitors are not Enabled. There are Overrides applied to each group to enable the Monitor and apply a threshold - different threshold for each group.
During some BAU tuning I could see that some of the above Monitors were appearing as Top-Talking alerts. Further investigation showed that alerts were being triggered by drives that momentarily dropped below the applied threshold. I re-created the Monitors
from 'Simple Threshold' to 'Consecutive Samples' and set the 'Number of Samples' to 6 @ 3 minute intervals.
What I am seeing is that alerts from the above Monitors are still appearing as Top Talkers. When I check the Health Explorer of repeating alerts I can see the disk space is staying the same, below the applied threshold but the health is turning healthy then
back to unhealthy. I have confirmed each noisy Object has the expected threshold as per its dynamic group allocation and have also confirmed the drives are not fluctuating above and below the threshold. One thing I have noticed is that some drives Performance
View is patchy - lots of dotted lines between the coloured lines.
Its almost like the Monitor moves a Logical Disk Object into unhealthy state in the correct (and expected) manner, then it somehow picks up an incorrect threshold which is below the current usage level. This moves it into a healthy state only for the
whole process to repeat. For example: Drive X: on a server is very large, the Group that it sits in has a threshold of 102400MB, its current usage is ~stable at 45500MB. Looking in Health Explorer I can see 3:01pm green state/ 45573 last sampled value/ # of
samples 1 | 3:16pm yellow state/ 45573/ 6 samples | 3:34pm green state/ 45572/ 1 samples | 3:49pm yellow state/ 45571/ 6 samples | 4:01pm green state/ 45425/ 1 sample etc etc.
I'm scratching my head on this one and would appreciate any suggestions or assistance.
Thanks
BT

Thanks for the reply. It is not just one server / drive this is happening on. I am seeing it on everything; once they go into an unhealthy state they periodically go healthy and back again with no change in disk free space. Just to elaborate on how it is
setup; a Monitor has been created for each OS version (2003, 2008 and 2012) and a separate Monitor for Warning and Critical so 6 Monitors in total. Looking at the Warning Monitors; they are created with a threshold of 5120MB for 6 samples and set to disabled.
The following groups have been created and the following thresholds added:
Group 1 (less than 60GB size): override added to enable. This group will then pick up the 5120MB threshold.
Group 2 (60 – 250GB size): override added to enable and override added for 10240MB threshold
Group 3 (250 – 500GB size): override added to enable and override added for 20480MB threshold
Group 4 (500 – 1TB size): override added to enable and override added for 51200MB threshold
Group 5 (>1TB size): override added to enable and override added for 102400MB threshold
One drive I was looking at was in Group 2 (threshold of 10240MB), it was staying at approx. 8500MB but periodically going into healthy state then after 10mins (6 polls @ 2min intervals) back to unhealthy. This process repeats once or twice per day.
I am wondering if the Object is somehow picking up the threshold of the Monitor (5120MB) then going back to its correct overridden threshold. I have setup some test groups and monitors in a lab and will review the results over the coming days.
When the monitors were setup as 'Simple Threshold' this worked fine but were noisy due to drives spiking downwards. It was only when I re-wrote them as 'Consecutive Samples over Threshold' Monitors that this issue has started occurring.
Thanks

Driver for HP 1661C Logic analyzer

I'm looking for an instrument driver for an HP1661C logic anlyzer

Hi,
Unfortunatly we do not have a driver for that instrument at www.ni.com/idnet. We do have some similar instruments such as the 1650B 80-Channel Analyzer. These drivers could be a good place to start at when developing your own driver. We have documentation, model instrument drivers, and driver templates to help at :
http://www.ni.com/devzone/idnet/development.htm
We also have a syndicate of third party vendors that specialize in National Instruments' products and services. Some of the vendors specialize in driver development. I would suggest contacting one of the Alliance members at:
http://www.ni.com/alliance
An instrument driver is a collection of functions that implement the commands necessary to perform the instrument�s operations. In short
, someone read the instrument user manual and implemented some of the functionality in a program for the end user. Instrument drivers are not necessary to use your instrument.
There are example VI's in LV on Instrument Connectivity. If you go to the Help menu >> Examples.. >> I/O, you will see a couple and Examples.. >> Fundamentals for File and String manipulation. I would suggest tweaking them to suit your application. Also the specific command that your instrument responds to can be found from it's manual.
Some useful resources for your application are
ni.com > NI Developer Zone > Development Library > Instrument Connectivity

Hope this helps!

Is update approved for specific group via powershell?

Hello,
I have a script that auto approves updates based on release date for specific groups. The script checks to see if the update has already been approved (e.g. isApproved) and either skips it if it's already been approved or approves it for my specific group
(e.g. $update.approve("install",$wsus_group)). The problem I'm running into is if I approve Update1 for GroupA, then later check Update1's isApproved to see whether or not I need to approve it for GroupB, Update1's isApproved is $true and therefor
my script skips approving it for GroupB. I've checked the update's object and I don't see a multi-valued var for groups that its been approved for. I've started to poke around with other
Microsoft.UpdateServices.Administration namespaces but I don't see one that has the info I'm looking for.
So, how can I view what updates have been approved for GroupA vs GroupB?
Thanks!

Hi Joey,
If you want to approve updates to multiple groups, and also want to check if the updates have been approved to the groups, please check the script below:
This can examine one computerGroup and find updates not approved for one or multiple other computer groups.
$serverName="localhost"
$targetComputerGroup="BaselineGroup"
$checkForMissing="MissingGroup1,MissingGroup2"
[void][reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration")
$wsus=[Microsoft.UpdateServices.Administration.AdminProxy]::getUpdateServer($serverName,$false)
$computerGroup=$wsus.GetComputerTargetGroups()|ForEach-Object -Process {if ($_.Name -eq $targetComputerGroup) {$_}}
$UpdateScope=New-Object Microsoft.UpdateServices.Administration.UpdateScope
$UpdateScope.ApprovedStates="Any"
$updateScope.ApprovedComputerTargetGroups.Add($computerGroup)
$Approvals = $wsus.GetUpdateApprovals($UpdateScope)
#At this point we have all of the updates assigned to the $targetComputerGroup
$report= @()
write-host "Querying for all Updates approved for $targetComputerGroup"
foreach ($Approval in $approvals) {
$record=""|Select-Object ComputerGroup,UpdateName, UpdateID
$record.ComputerGroup=$wsus.GetComputerTargetGroup($Approval.ComputerTargetGroupID).Name
$record.UpdateName=$wsus.GetUpdate($Approval.UpdateID).Title
$record.UpdateID=$wsus.GetUpdate($Approval.UpdateID).ID.UpdateID

Logical Disk monitoring - Overrides galore?

Hi all!
We have a number of systems with differing needs for storage thresholds. The defaults work the majority of time, but there are a number of 'buckets' our disks need. For example, some disks might warrant an error at 5GB free, 10GB free, or even
25GB free. Let's pretend the percentages aren't important for now.
Just to be clear, is it correct that I would need to create 2 (system / non-system) * 3 (2003, 2008, 2012) = 6 overrides for every single bucket I want (and make no mistake, we need way more than 3)?
This seems absurd. I can handle dumping the appropriate logical disks into buckets based on PowerShell or some other programmatic method. Creating
overrides seems a bit more complicated. Is there not a simpler way to do this?
I'm comfortable using PowerShell, but the 600 line example above seems like a pretty steep requirement for a very basic and common task (that is cumbersome and delay ridden when using the SCOM console).
Please tell me there is an easier way to create overrides for logical disk space monitoring!

I run into the same questions and problems with most customers. What I always suggest is to give the power to the server and/or application owners. This can be accomplished a few different ways, and I have done this by using a registry entry or by using
a file on the root of each disk.
For example, everyone gets default thresholds for disk monitoring. If the server owner wants different thresholds for a disk on their server(s), then they would create a csv file on the root of each disk in which they want different thresholds (or create
a registry entry with similar threshold configuration).
If you modify the built-in disk monitor by checking whether this particular file is present, then read the file to get the custom thresholds and bypass the default thresholds for monitoring that particular disk. The built-in disk monitoring script is pretty
long, but if you know a little VBscript then you should be able to figure out where to add more logic to retrieve custom thresholds based on csv file or registry information.
You will need to put this monitor in a new pack (for example, Windows 2008 Operating System Extended), and disable the unit monitor in the vendor pack. This would end up being 2 new "extended" packs if you were to also do this for Windows Server
2012.
This will effectively remove the responsibility from the SCOM admin to manage hundreds (or more) disk monitoring thresholds, and place the responsibility into the hands of the server owner. This has worked quite well in any environment I've work in.

Internal hard drive for use as scratch disk

Am running OS 10.4.11 on a dual core 2.3 Ghz PowerPC G5. Want to install a 2nd internal hard drive for use as a scratch disk w/ FCP and for my media files, etc. Given that I can only accomodate an SATA I drive w/ 150 Gbps transfer rate what might some decent choices be for a 500 Gb to 1 TB drive suited for video (and a PowerPC G5)? I'll also be adding an external drive for backup if anyone has any suggestions.

Thanks for the recommendations. I had been looking at the Hitachi CinemaStar series but you have to reset the drive to SATA 1 for use w/ a G5 PowerMac. Resetting the drive, according to Hitachi, can only be done on a PC which I don't have access to. And I think that holds true for all their drives that are not strictly SATA 1.

Hard drives for use with Logic

Anyone have any opinions on the best hard drives for both the project files, as well as extra external drives for keeping samples on? I'm pretty sure that at this point, my hard drives are creating more system locks than my processing speed.
According to the "activity monitor" my processing and RAM are definitely not working to capacity.
Is there a threshold where drive capacity gets too big and starts to affect performance, or does it really not matter?
Thanks,
-jeff

I've used a lot of lacies but I don't recommend them anymore and won't buy one the next time I get a drive. too many things have gone wrong with them over time, I have a hard time trusting them. I currently use a lacie 500GB d2 drive (the long one with triple interface) for my sound library and project files using FW800. so far so good, but it will be relegated to backup drive as soon as I get a g-tech drive.
I'm probably going to go for a G-RAID 500GB. I'm even considering getting an e-SATA one to use with my MBP using an e-SATA card.. I like the idea of having desktop-class data throughput. and also I've been eyeing off the liquid mix for my MBP, so having the firewire bus totally free for that would be not a bad idea at all..
I've head nothing but good reports about g-tech drives, the only bad thing is that there never seems to be any stock available, you always have to back order. maybe this is a good sign?
I'd second the opinion already posted that as far as firewire goes, g-tech are the best choice for serious work.

Automounts for specific groups

Hi,
I set up automounts via AFP on a 10.3.9 server, they work fine on Panther and Tiger clients. Now I want to assign the automounts to specific groups of users (or computers, as my users don't switch machines). Right now the automounts appear on every client on the subnet but I want Group A to get share A and NOT share B which is only for Group B and so on.
At the moment all users have local home directories, no OD etc in use. DNS and OD master are set up and run fine.
Is there a way to accomplish this task?
I am thankful for every hint.

I am looking labview driver for Tektronix TLA704 logic analyzer

I need this labview driver desperately, I am very appreciated if you have it and courtesy me a copy.
Thanks
Tys

phone: 214-480-0902

I did some looking around on the Tektronix web site.
Tek does not seem all that interested in supporting the
TLA704 in particular, or LabView(tm) for logic analyzers
at all. IMHO the Tek site sucks when you need to find
information in depth.
I looked through National Instruments site too. Now on this
site it was easy to find what I was looking for. Good job.
Developing a LabVIEW instrument driver for a logic analyzer
looks to be a non-trivial task for anything more involved than
starting a capture and waiting for the data to log. Depending
on the driver it could be real slow getting a load of data from
the logic analyzer.
It might be better to use the TLA programmatic interface
(TPI) to run the TLA704 by remote control over the Ethernet.
All the support for this comes with the analyzer software.
Though it's really painful to get it setup in Windows 98.
This way you could create a Windows program that runs
on your workstation to connect to the TLA704, set it up,
start a run, and download the data. Once the data is in
your workstation you can reformat for use by LabView.
I don't know that this would be easier than making a
LabVIEW instrument driver for a logic analyzer, but
at least all the software exists right now to control
the TLA704 remotely.
Charles.
I don't work for National Instruments,
or Tektronix or use LabView. But I use
logic analyzers way too much.

How to implement Micaz radio driver for specific embedded web server

Hi,
I want to implement a driver for radio communication between MicaZ sensor
I don't know how to begin and what's the first step.
Should I learn about MPR 2400 CA ?
Thank you .

med_alpa,
I can be of most help if you tell me what National Instruments' hardware or software you're using. You can try looking here for current NI resources regarding Crossbow items: Instrument Drivers: Crossbow
If your question is founded in non-NI hardware and software altogether, perhaps others from the community can help you further.

Ideas for Server or Net-Drive for Small Group

We're (two of us at the moment) running Final Cut Studio 3 and I'm seeing the need for a common drive for shared assets and project files. I'm not looking to get a huge TV production-level system, but something that is fast and easy for us to connect to.
Back in the day, I had the old Xserve with the fibre cards. I'm sure I can get something that serves a similar purpose, but without the $12,000 price tag.
Any suggestions is much appreciated. Thanks.
-Alex

Yeah, our workflow is not pro at all really. Pro in the respect of the look and the quality of the files, but we're former designers that have a few years of FCP under our belts. Started with the old Sony BetaSP deck and all.
Up to now, I've kept a main project file for every campaign, with individual bins containing the sequencing and assets for each client. Very easy to keep track of. I always kept my files local on my GRAID2, then transfered the finished exports to the server. I also have backups of these project files and their assets. Now, I'm media-managing each client sequence so the other editor can have everthing just for that client.
Many of our spots are motion-graphic based. Lot's of Photoshoped 24-bit PNG files, Title 3D and Cinema 4D animations using the Animation+ codec for alpha. I know people say to use image sequences, but FCP doesn't seem to handle these too well. Bogs my system down too much.
I've been setting up my sequences in ProResHQ, HDTV 1080i (16:9), square pixels and things look gorgeous. Unfortunately, most cable stations these days want h.264 files which isn't a rich looking, but they look nice on TV.
Sorry for the long post.

How to show specifc filters for specific groups

Hi,
I have a sitecollection with lists A and B. There are two subsites.Each subsite has lists C and D.
Admin has access to everything.
Non Admins group(s) have access to specific subsite
I understand that search results are security trimmed with user group permissions.When Admin searches, he should be able to see results from all lists and he should also see filters A,B,C and D.
When non admin searches, he should be able see results only from specific subsites to which he has access and should be able to see the filters C and D.
How can I do this? The below approach I had involves creating lots of pages is there a better way.
I could create 4 pages at root sitecollection for 4 lists and add them to the SearchNavigation in SiteSettings with audience targetting.In each of those 4 pages, I can add SearchNavigation webpart with Search Results and Search box webpart and query transform
to fetch results for that specific list content type for that respective page.
At each subsite, I would have to add two pages with audience targetting in Search Navigation for lists C and D . In each of the two pages, I have to add the search Navigation webpart and results webpart which is query transformed for that specific list.
So in total I would require 8 pages ,4 for sitecollection and 2 each for 2 subsites.
How else can I achieve this?
One approach I had was to create a single result page at sitecollection level and add this url 4 times with different url parameter matching the list content type along with. audience targetting.This would ensure that, if Admin sees the page which has search
navigation webpart, he would see 4 links and others would see 2 links.
Similarly in subsite, I can add the two links to same result page along with two url parameters, 1) path( to that subsite) and 2)content type .
But is there a way where we can specify the contenttype and path in the url?
I tried results.aspx?contenttype=mycontenttypename&path="my url" but it does not work.
Is there any better way to achieve the same?

Unfortunately, it didn't work. While I was able to add the second cover art, when the song from the album played it still showed the first album cover. While the second album cover won't show unless I click the "part of a compilation" box in "cmd-i > Info". This will work for the one song that I have checked. Although I can select the songs in the album, whenever I attempt to assign the specific artwork to those songs for, the artwork applies itself to all the other songs on the cd. Any other suggestions ? All are greatly appreciated. Thanks.

How to load specific driver for specific device not having PnP-ID?

Hello,
as mentoined in a previous post I'm up to adapt an exisiting PCMCIA-based PC Card driver so that it can be used with a PCMCIA/USB adaptor (by using it's driver's IOCTLs), and already had
some success on it: My driver loads and I can read files (for example, in Windows Explorer) from the card as it did before in "PCMCIA version" (I intend to support both with the same driver, which seems
to work at the moment). As it did before, the driver currently creates a MTD (memory technology device). My main "problem" is how to load the driver.
The situation is a bit complicated, I try to give as much details as possible.
For better understanding
The PCMCIA/USB adaptor's driver usually has following device stack: PCMCIA/SUB adaptors driver -> USB mass storage device (USBSTOR.SYS) -> Diskdrive (DISK.SYS [->PARTMGR.SYS]). For more ease - to see if my driver works in general - I installed my driver
via INF using the PnP ID of the "USB mass storage device", with other words I "replaced" the USB mass storage driver with my own driver.
This is my problem
This means - and that is currently my problem - that may driver gets loaded regardless of what is attached to the PCMCIA/USB adaptor. Usually, when attached to PCMCIA, the PC card has a PnP ID the driver can be assigned to. In my case, I have no PnP ID for
the PC card, and the driver may stop because the attached device is not supported The driver will unload properly, but the device remains with error code (in device manager).
What I want to avoid
I already thought about filter drivers between USBSTOR and the PCMCIA/USB adaptor's driver (#1), or above the USB mass storage device (#2). If I'm correct, that means that I have to handle URB/CBW requests for case #1 or at least SCSI requests for case #2 -
but I'm currently not familiar with filter drivers, URB/CBW and/or SCSI. Porting the driver was quiete frustating until yet and I had to get familiar with a couple of technologies that belongs to the driver's functinaliy itselfs -
I hope you understand that I want to avoid getting familiar with more technologies than required.
I think there must be a way to check the device (PC card) at the PCMCIA/USB adaptor
before my driver will be loaded, as well as removing the deivce completely if the PC card was removed (so that it disappears in device manager). But I'm currently have no idea how to do that. Is it possible to
load my driver along the device/driver stack usually created by the PCMCIA/USB adaptor's driver?
Some answerers likes to refer to WDK documentation and samples. In such case - because of their complexity, it would be nice to get a hint about where to start.
Have much thanks in before for any suggestions!
Regards,
Willi K.

Today's memory cards (like CFC) manage their FTL (flash translation layer) in their firmware. Our PC card is quiete old technology and does not have such firmware, this is why Windows cannot recognize the file system (FAT). For example, a request to offset
0 may be somewhere else on our PC Card.
I followed your suggestion and used the HWID of device that appears "above" the USB mass storage device, and my driver seems to work as it did before - OK, made no difference.
But if my driver does not recognize the card (because it is not present or it is another PCMCIA device -> STATUS_NOT_SUPPORTED or STATUS_NO_MEDIA in driver entry), and the device is shown with exclamation mark in device manager.
Two questions remain:
- How can I ensure that other drivers may attach if my driver does not support the device inserted in the adapter?
- How can I force a "re-check" of my driver if there was no card present when driver was loaded?? -> Note: A disk drive always appears in device manager - regardless if a device is attached to the apator or not
