HI all,
can I override this monitor on one concrete logical disk and concrete server ?
thanx
Falcon

find out the monitor
right click the monitor --> overrdies monitor --> speical object of logical disk
select the require hard disk e.g. c: and with path of your server name

  • Logical Disk Free Space Monitor - Slow to detect low free space

    We are using the built in two trigger (MB and %) logical disk free space monitor in SCOM 2012 R2. We have setup overrides for MB warning and critical for both system and non-system drives and for a group containing disks we do not want monitored. The monitor
    actually works fine, triggering an alert when both the MB and % free criteria are met. The problem is that it takes almost an hour for the initial alert to fire. After the initial alert, if I further fill the disk to push it from warning to critical, the alert
    changes within the specifiec interval, which we have left at 15 minutes. The alert also clears using the 15 minute interval.
    Has anyone else seen this behavior with this monitor? A disk monitor that takes an hour to fire is not going to be very useful.

    I wanted to see for myself if there was anything else that I might be missing, so I opened up the Windows 2008 Logical Disk Free Space monitor XML and noticed that there is a NumSamples configuration that is set to 4. So, if the interval is 15 minutes, the
    disk would have to exceed both threshold types for 4 consecutive intervals in order to change state and generate alert. This would be a minimum of 1 hour before an alert is raised with the default 15 minutes interval.
    Unfortunately, NumSamples is not overrideable in the monitor type, which is too bad... The only way to get an alert sooner than one hour is to override interval. For example, if you want an alert within 20 minutes, override interval to 300 seconds (5 minutes).
    Here is the code - see for yourself:
    <UnitMonitor ID="Microsoft.Windows.Server.2008.LogicalDisk.FreeSpace" Accessibility="Public" Enabled="true" Target="Server2008!Microsoft.Windows.Server.2008.LogicalDisk" ParentMonitorID="SystemHealth!System.Health.AvailabilityState" Remotable="true" Priority="Normal" TypeID="Microsoft.Windows.Server.2008.FreeSpace.Monitortype" ConfirmDelivery="true">

    <SystemDriveErrorPercentThreshold>5</SystemDriveErrorPercentThreshold>
    <NonSystemDriveWarningMBytesThreshold>2000</NonSystemDriveWarningMBytesThreshold>
    <NonSystemDriveWarningPercentThreshold>10</NonSystemDriveWarningPercentThreshold>

    <NonSystemDriveErrorPercentThreshold>5</NonSystemDriveErrorPercentThreshold>
    <NumSamples>4</NumSamples>
    </Configuration>
    </UnitMonitor>
    This proves 2 things:
    1. Your testing proved that the monitor is working as designed - you got an alert in about an hour
    2. This is a bad design at best, or a bug if you wish, as NumSamples should not be a hidden configuration - it should be exposed in override parameters in the console.
    This should be fixed by Microsoft.

  • Need to separate drive alerts with Logical Disk Free Space monitoring in SCOM 2012

    I have an interesting need here to separate our SCOM alerts for Logical Disk Free space so that one alert is for OSSystem drives ONLY (C:/D:) and the other monitor alerts on all APP drives only (E:, etc). So far we have had great success using Kevin Holman's
    blog post.
    http://blogs.technet.com/b/kevinholman/archive/2009/11/24/writing-monitors-to-target-logical-or-physical-disks.aspx
    We have overrides set so that the monitors report ONLY the percentage of free space left and ignores any MB threshold. So far so good, the alert comes in that host A reports low disk space on D: at 2.345...% free or host B reports low disk space on F: at
    4.567...% free space etc. Now that we have our monitors working within the Windows Server classes Logical Disk, we need to set these monitors so that one is just for C or D drives with the alert named system Logical Disk Free Space OS Disk Warn and the other
    monitor just reports on E - Z drives (excluding C or D) with the alert named Logical Disk Free Space APP Disk Warn.
    We are very new to SCOM so I made the rookie mistake of creating a dynamic group for all Windows Server 2003 Logical Disk class that only includes Device Name = C or D. But found out too late you cant point a monitor to a group, it has to target a class.
    And using the current monitors we set up with the above blog uses the correct logical disk class, but it doesnt care what instance (device Id = value), it will report low disk space on ANY logical drive. How in the world can we separate and exclude these monitors
    so that one alerts only on OS disks (C and D) and the other only alerts on app disks (E through Z)?

    Hi Kevsharp,
    Quite confusing after reading your question.
    So based on your requirement, What i understand is you need separate alerts for all the drives of the disk is running at low or out of space right ?
    For the above just create a simple performance counter monitor and use the same counters as kevin has used in his blog.
    Now Target: Use Windows server operating system (This will target all the Windows operating system agents in your SCOM. If the specified discovery MP's are installed).
    Set a threshold Below 10% is critical or what ever. You will get the alerts in your console.

  • Logical disk free space counters missing for server 2008 r2 and 2012 r2

    I'm trying to get low disk space alerts for server 2008R2 and 2012 R2.  While the monitors exist for 2008 and 2012 (Not-R2), they are missign for all R2 operating systems.  Any idea how to either obtain these monitors, or create them so I can
    get alerts for % disk free alerts?

    What is your meaning of " monitors exist for 2008 and 2012 (Not-R2), they are missing for all R2 operating systems."? Does it means that the monitor is missing on all Windows 2008 R2 and Windows 2012 R2 machine or it just a blank circle ?
    By default, Windows XXX Logical disk Free Space monitor is enable for all windows XXX. You may check whether an override to disable it. Moreover, Windows Server XXXX Logical Disk Free Space (%) Low and Windows Server 2008 Logical Disk Free Space (MB) Low
    is disable by default and you should manually enable it.

  • Windows Server 2012 Logical Disk Free Space (%) Low

    I enabled the monitor "Windows Server 2012 Logical Disk Free Space (%) Low" and configured a low threshold to test. I started to get a bunch of warnings from servers, for example:
    The disk \\?\Volume{ee0222ed-16de-40a5-af89-f95db3fdf5a4} on computer PC is running out of disk space. The value that exceeded the threshold is 11% free space.
    Now I checked on the server, and all the disks have more than 11% free space. Additionally, I don't see any disks with such a name/guid.
    When looking at the additional knowledge of the monitor, I see that it is using the following information:
    Object Name: Logical Disk
    Counter Name: PercentFree 
    My question is where is this disk coming from, and how can I avoid these disks from creating false alarms? When looking in the Windows Server
    From my analyzing the DB, I see that these are the partitions on the server without a volume letter. Any way to avoid getting these discovered and/or alerts, without overriding each one?

    Hi,
    These "strange" disks are called mount points.
    They get discovered by the "Mount Point Discovery Rule".
    Go to your authoring => rules => search for the rule above and disable it.
    If you want to remove all the instances in your environment you need to use Remove-SCOMDisabledClassInstance
    powershell cmdlet.
    More info on the cmdlet can be found here:  http://technet.microsoft.com/en-us/library/hh920257%28v=sc.20%29.aspx
    If you have any more questions please do not hesitate to ask
    It's doing common things uncommonly well that brings succes. Check out my SCOM link blog:

  • SCOM 2007 R2 : Logical Disk Free Space : Did not Alert

    Hello reader ,
                   I know this might be a repeated hearing for you. I have been sitting wit this issue for many hours now. I would like to understand where or what am I missing.
    We have the default 'Logical Disk Space' Monitoring enabled for ALL servers in our environment. In one SQL server, non-system drive(E:) went beyond the warning(2000MB and 10%) and Critical (1000MB and 5%) Threshold.The total space allotted for the Drive
    E: was 79GB. Now the total space left today morning was 698MB. But no alert was triggered.
    I checked the following
    If the  health service watcher was available. - Yes it was.
    If the Space really dropped to 698 - Yes it did. I verified from Performance Report.
    I checked if there are any overrides - Nothing specific found.
    In most of the blogs they said me to check if both criteria was successful - As shown above it is clearly matches.
    Any idea why this alert was not fired ?  
    S.Arun Prasath HP ARDE TEAM

    Thank you Agarwal ! To Answer your Question.
    1) verify the monitor settings again.
    => I did this N number of times.
    2) ensure there are no overrides
    =>  I did this too.
    3) ensure that monitor properties are set for the correct Windows OS (same as that of the server).
    =>What Do you mean here ?. I did not change any settings , it was there by default. No change was done at all.
    4) also confirm that you do not have any other overrides on the two aggregate rollup monitors for "logical disk free space". These aggregate rollup monitors are just below the unit monitor in SCOM console.
    =>Those Aggregate Rollup monitors are disabled. As we already have this unit monitor Enabled. There is no link to Aggregate monitor.
    If all these settings are true, then can you try this. calculate the exact value in both % and MBytes according to your server, put the same values in your monitor through an override and repro the low disk space condition,. you should get an alert.
    => Not so easy to do this in prod. So will keep you posted when this is tested. Looks like this is the only way we can confirm if the alerts are sent.

  • How to enable Logical Disk Free Space

    Hi 
    I have installed SCOM 2012R2 and configured monitoring for Windows 2012 R2 HyperV cluster. i think i configured most of the part but i could not able to see my logical disk free space.
    I treid to enable In Monitors --> Windows Server 2012 Logical Disk --> "Logical Disk Free Space" but its grayed out. 
    can anyone tell me how to monitor my Logical Disk Free space and Physical Disk Free Space.
    Here i attached the screenshot of my SCOM - Montiors
    Regards

    Thanks Gautam,
    even i go through one by Monitors, i don't see any option to enable monitor. looks like its grayed out.

  • How to make a proactive view of the Logical Disk Free Space

    Hello,
    I was wondering how I could make a view (preferably within a dashboard) that monitors the state of the Logical Disk Free Space values for one or more predefined groups. I can only get this to work with line diagrams but that is pretty hard to read.
    I would like to make views like:
    1) A simple state view that shows the state of the servers (or disks) in three state form (1. Healthy: 80% or lower; 2. Warning: Between 80% and 90%; 3. Alert: 90% or higher).
    2) A view of actual percentages of the disk drives in a table form rather than the usual line diagram.
    I prefer the first one the most and seems to be the easiest aswell but I can't seem to get this to work.
    I hope that this is possible any like to know how to achieve this.
    Thanks in advance,
    Bram

    Hi Bram,
    I think you need to create a new dashboard view for this.
    Make a new management pack for this.
    Once you create a new management pack.
    Go to monitoring TAB
    Locate the management pack there and right click and select new Dashboard.
    Create a summary view dashboard and then once it is created on the right hand side you will see something like
    Performance (Which i edited as LDS report for last 24 hrs as per the screenshot)
    Above that you will have a configure option. Click on it and mention the Object, counter and instance and of the LDS performance counter and mention the report duration (Last 1hr or  24 hrs )once you do this dashboard will start collecting the report
    for you.
    Once you scroll down the report you will get the list of servers in which space is low and how old is that alert
    Below is the screenshot for your reference.

  • Logical disk free space is low.

    Hello,
    I am getting this alert "The disk  on computer abc.com is running out of disk space. The values that exceeded the threshold are x% free space and "y" free Mbytes. Can any one clearly explain the issue and what is the proper resolution.
    Thank you.

    Hi,
    this parameter is configured on your site properties (Administration \ Site Configuration \ Site).
    It means that free space is missing on your server.
    Proper resolution would be to modify the alert threshold or add some disk space.

  • Windows Logical Drive - Free Space Report

    Hi SCOM Experts,
    I am able to generate the Free Space Report but it is not accurate for windows 2008 R2.
    I am using SCOM 2012 and report is good for windows 2012 servers. Any Help appreciated

    Hi There,
    My way of getting this report is by using a SQL Query. I have a SQL Query which i Run in the Operationsmanager DB to get the Disk space below 20% on all my agents. Use the below SQL Query to do it.
    My SQL Server uses GMT time (London UK time) so i enter london time here.
    Just enter a time exactly 1Hr before time when you are running the query (If you are running the query at 1:00PM by yourself then in the bolded portion enter the time as 12:00PM).
    select Path, InstanceName, SampleValue 
    from PerformanceDataAllView pdv with (NOLOCK)
    inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
    inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId
    where SampleValue < '20' and CounterName='% Free Space' and TimeSampled > 'YEAR-MM-DD 12:00:00.00'
    order by countername, timesampled

  • Hard Disk free space lick after system restore windows 8.1

    I did a system restore and after that, the laptop was functioning slowly. I realised that the disk usage was spiking. Later I realised also that I was constanlty loosing free space from my hard disk without downloading anything or any action. I run the windows
    performer recorder when the spikes occurs.Link in OneDrive https://onedrive.live.com/redir?resid=26DCEC24336471AC%21106  . Furthermore when the laptop is on idle the disk usage goes to 100%. Task manager shows that most of the usage is from svchost.exe(defragsvc).
    (I dont think it is a scheduled act from windows to run defragging at the moment). What could be? Any advice?

    Hi,
    From your recorder information, we could see these 5 process below take high disk space:
    WPRUI.exe
    System
    vprot.exe
    avgui.exe
    avgcefrend.exe
    Since you run the Windows performance toolkit to trace the log, exclude WPRUI.exe and system. It seems you use AVG product.
    I suggest you disable or uninstall them temporarily to check if the disk usage decrease.

  • How much hard disk free space?

    My mini is used almost exclusively as a media "appliance", hooked up to a large flat panel TV. Installed on the mini itself is the operating system and little more. Attached to it are several (currently 4) large (1 TB) firewire hard drives crammed with movies and TV episodes (I have digitized my extensive DVD collection with Handbrake plus I have nearly stopped buying new DVDs in favor of downloading from iTunes).
    My question is how much (what percentage) of these external drives needs to be left empty in order for them to operate with reasonable efficiency. They are virtually "read only" in that once I have uploaded a video file to them, it sits there until and unless I want to watch it (or unless I decide to download it to my MacBook and/or iPad to take with me for watching on trips).
    I recall reading years ago that one should keep 10% or so of a hard disk free. Elsewhere, I read it should be as much as 20%. But it strikes me that that would mainly apply to a start-up drive that is constantly being read and written to, not a drive like mine that mainly just stores files and occasionally reads from them.
    To re-emphasize, I keep much of my start-up drive free except what's required for the OS so the issue isn't that but just the external storage drives. I hate to waste as much as 400GB of space (100GB on each of four 1 TB drives).

    I think your argument has some validity, but since you have a lot of time and effort invested in this project, I personally wouldn't try to cut things too close to the bone.
    With drives of that size, I'm comfortable with the 10% rule; perhaps even 5%.
    However, with the price of drives falling, perhaps gradually transitioning to larger capacity drives would be a good idea.
    My understanding is that most modern drives dynamically re-allocate data from sectors that the drive controller senses are going to fail -- so having an adequate percentage of "wiggle room" makes sense to me.
    "Wiggle room" may also come in handy if you ever need to rescue a drive using a utility like DiskWarrior, which needs space to rebuild directory structures.

  • Boot, shutdown slow after erasing disk free space

    On the advice of a friend I used Disk Utility to erase free space on my MacBook Pro disk. Used the 'zero' option. At the end of the erase procedure it tried to run a routine to create a 'backup file'. There was a "Skip" button and because it was late at night I skipped it. Still took 10 minutes to complete. Since then it takes almost 2 minutes for the thing to boot and to shutdown - was approx 30 seconds for boot and maybe 10 or 15 for shutdown previously. Once it does boot, it takes even longer to find my wireless network. I tried verifying the disk (it's OK) and repairing permissions, both to no avail. I have no apparent battery issues. Anyone have any other suggestions before I start from scratch? TIA.

    Yes, I tried DiskUtiliy from the CD, didn't work. Eventually gave up, backed everything up and re-installed OS X. After downloading and installing all the updates it now boots and shuts down as expected. I think I'll stay away from the Erase feature...
