SCOM cluster disk space monitor

Hi Guys,
Can we monitor the cluster disks thresholds by taking the samples as we do in the logical disks??
Because i cannot see that option coming in the cluster disk space monitor when i am overriding the monitor.There is no option for the number of samples coming in that. I want the monitor to check the utilization three times and if it exceeds then generate
an alert.
Thanks
Ashish

Hi,
As you mentioned, threre is no option for the number of samples, you may need to rewrite the MP.
Please refer to the following links which should be helpful for our question.

Disk Space Monitor

hi
I have set up a logical disk space monitor for windows 2012 servers on my Operations manager 2012. The threshold value is 500MB. However, No alert is generated even when my disk has exceeded 500MB. It works when i set the threshold below 100 MB. Can you
please help out on this? Is it because of the wrong instance ?
The object has been specified as "Logical Disk"
Counter is %free space and the instance is the C:\ drive.

Does you using Logical Disk Free Space, from Windows Server OS Management Pack, in monitoring the free disk space?
Case 1 Logical disk Free Space Monitor:
It will generate alert if both the conditions, disk free space and % of free disk space, are below threshold.
Recommendation: You may enable another monitor ,Disk Free Space (MB) Low, which is disable by default.
Case 2 you own custom monitor:
Please dump your setting for troubleshooting

Disk Space Monitors

If you can't get the customization for space alerts with SW you can always use one of many free utilities:
http://community.spiceworks.com/product/47308-disk-space-monitor

We have quiet a few servers on our network.
I want to be alerted and have a ticket created for when their disk space is at a certain point.
Spiceworks notified us when there was less than 10% space free which is great. But we then realized that we would like to be notified at different percentages and also notified for how many GB are left instead of a percent. Sadly, There are only a few options and we would like to have a monitor that tells us less than 50 GB or less than 20 GB, but we can't seem to figure out how to add more options that it offers.
HELP WITH THIS ASAP, would be greatly appreciated.

Operations Manager log flooded with 11903 errors due to "Virtual Hard Disk free disk space" monitor

Cluster Disk Space Report - DESPERATE

Please can someone help the worldwide SCOM community and give us a Cluster Disk Report?
Name your price - I will pay for this.

Here's how to do it. We have a 2-node cluster, NODE1 and NODE2. The Cluster Name is WATER. We want a report for a file system that's on the cluster called Backups (the M: drive, but the drive letter doesn't matter, as SCOM uses the name of the file system).
Start with a Performance Detail report. Change your date range to whatever you want. Create a new series. Click on "Add Group" in the "Series Details" section (make sure you pick "Add Group", this is important). Find your cluster name, WATER and choose the
Windows Computer object.(it's odd, but trust me on this!)
In the Rule section, in the Search by Name tab, find the "Windows Server Cluster Disks Monitoring" MP. Pick the rule you want to run the report for, click OK. Back in the Rules section, select "Specific Instances" and find the name of your disk you want
the report for (in our case, "backups").
Here's what the settings/parameters look like when you're done:
Click OK and run the report. That's it!

Logical Disk space on a virtual Computer (not a Server) in SCOM 2012

Hello all-
   I have a sort of unique situation for our SCOM environment. We are already doing logical disk space monitoring on all of our SERVERS with no issues. Now we have one user who requires monitoring on their computer. This is really
a virtual workstation, as opposed to a real computer.   Since it's virtual, it's really online all the time.    Whether its right or wrong, they are using this virtual workstation sort of as a server. Anyway, they want me to
monitor the disk space for the C drive on this virtual computer. I'm having difficulty setting up such a monitor on a computer like that...
I got the SCOM agent installed onto the computer. SCOM is reporting it as being "Healthy".   Now how can I define a logical disk space monitor for it?   I attempt to create a monitor:   Windows Performance Counters,
Static Thresholds, Single Threshold. Then how can I direct the monitor at the C drive on the computer? I have to fill in the Object, Counter and Instanace. Normally I would click on the
Select button, then I would type in the server name and hit Enter and it would bring up all the objects it will allow me to monitor. Unfortunately it doesn't let me type in the computer name and hit enter in the same way. When I
do so, it says "The network path was not found". If I click on the
... button next to the Computer field, it brings me to a Select Computer screen. In here, I am type in the computer name and then I click
Check Name and it does appear to find it, and it underlines the computer's name.    So I then click
OK to bring me back to the previous screen where it presents me with the same "The network path was not found" error immediately. So I can't seem to navigate to the computer in SCOM and select the C drive, as I would be able
to for a server.
I tried to sort of force it in, instead of browsing for the computer and selecting the C drive. I simply put
LogicalDisk in for the Object then Free Megabytes for the Counter, then
C: for the Instance (as shown in the attached screen print.
Then I just applied my new rule to the computer via SCOM. I don't get any error messages when setting it up that way, but it certainly doesn't work.
So with all that said, can anyone help me out setting up a logical disk space monitoring for a COMPUTER in SCOM 2012 SP1 please? Please let me know if you need any more information!

Thanks, that would probably do it, I'm going to keep that as my backup plan. However, my current feeling is that it might be a bit overkill to install a whole management pack, when all I want to do is monitor a single C drive on a single workstation.
The rest of the monitors in the management pack I wouldn't have any interest it.   Let me ask you a question maybe you will know the answer to... Shouldn't I be able to monitor that drive even without that management pack installed?   I
mean some combination of settings for the Logical Disk Space rule in that management pack works for computers/workstations. Shouldn't I be able to reproduce that one single rule without the management pack? Does anyone have that management pack
installed? Could you possibly look at the Client OS Logical Disk Space rule and send me some screen shots or something?   Or am I missing something? Is the management pack needed for other reasons in order to monitor this?

Agentless Mode - Monitor Disk Space

Hi guys, I have 100 VMs running Windows 7. All I wish to do is monitor the free space on them so I installed the agent on a server VMand I'm trying to use it as a proxy to agentless monitor disk space on them. I can't figure out though how to get the disk
space monitor to fire against them agentless. It doesn't seem to discover the disk instances against them. Is there a guide for this somewhere?

I should have been more specific.
There are no internal firewalls software or hardware based
Remote registry is ruing on all machines.
The SCOM action account is a full admin on al client machines
The issue is that the logical disk are simply not being discovered agentlessly. How to troubleshoot this? I see messages like this on my Proxy agent:

Creating SCOM 2012 Logical Disk Space Availability View

Hi Everyone,
I am looking to create a SCOM 2012 Logical Disk Space Availability View and having a little trouble finding documentation on how to do this. It would be really handy to see all of the servers being monitored and how much free space they have all in one view.
Has anyone created a view like this before.
Thanks in advance for all your help.

Reports for Low disk space alerts in scom 2007

Dear Experts,
Is there any possible to get the Low disk Space alerts reports in SCOM 2007 R2.
1, I need reports for Last week SCOM sent alerts on Low Disk space for the servers list
2, Likewise I need SCOM Low disk space alerts reports for last month.
Can somebody please explain me with the steps and I played much with Reporting pane.
Thanks,

Hi,
The below code should work to get all servers that have alert of logical disk free space is low in specific period:
get-alert -criteria 'Name = ''Logical Disk Free Space is low'' AND TimeRaised >=''3/24/2014'' AND TimeRaised <= ''4/24/2014''' | select MonitoringObjectDisplayName,MonitoringObjectPath,Name,TimeRaised | sort MonitoringObjectDisplayName

Receiving an automatic notification from Windows Server when disk space is low

Hello,<o:p></o:p>
Does Windows Server 2012 R2 have any such functionality built-in to enable monitoring of disk space?
We have an old VB Script file that sends me an email when disk space gets low.
Also, the following post discusses the topic regarding Windows Server 2008:

Hi,
Windows Server 2012 stays the same on that topic, you still need some kind of monitoring on your disk space.
If you don't have a monitoring solution, like for example SCOM, you can for example with powershell do what you earlier did in VB script. Either you have a scheduled task that runs as often as you'd like, or you can utilize something called WMI eventing
to trigger on an event 'disk low' but thats a bit more complicated.
See below examples on some example scripts that you could use.

Disk path monitoring

I've a 2 node cluster that share a SCSI RAID.
I've enabled monitoring of disk paths from both the nodes (for RAID disk only). All other disk paths are unmonitored.
I've also enabled rebooting of the nodes if the disk paths fail.
When I disconnect the SCSI cable from one of the nodes, the output of "cldev status" shows the disk path status as "Fail" but the node does not reboot.
Is there something that I'm missing here?

In the following output d10 is the shared disk:

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.

SCOM only monitoring disk space of a group of servers

I have been looking for a way to setup SCOM to ONLY monitor the disk space on a specific group of servers.
We have a sandbox environment that consists of approximately 100 servers. The only responsibility we have is to make sure these machines are patched. Everything else related to the OS and Software is handled by the developers who own the sandbox,
so no other monitors are needed. Microsoft patches are failing because some of the C drives do not have enough disk space. Is there a way to discover these servers and only have the disk monitored? All other monitors in SCOM can be ignored on these
servers.
Thanks for any assistance that can be provided.

Without knowing what else you have in your SCOM environment, it could be a lot of work to start excluding this group of servers from all the other monitoring you have.
Other options you could consider are to allow the servers to be monitored, but somehow exclude those alerts from being sent in any subscriptions, or putting the components of those servers into Maintenance Mode other than the C: drives, but both of these
options will still collect information on these 100 servers and take space in your SCOM DBs.
You can refer to this page for how to use the free space monitor and override it for a group that will target your 100 servers. http://blogs.technet.com/b/jonathanalmquist/archive/2009/04/04/logical-disk-free-space-monitor.aspx

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">

<NonSystemDriveErrorMBytesThreshold>1000</NonSystemDriveErrorMBytesThreshold>
<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.
