Ops Manager: Reporting on Logical Disk % Free
I saw a few posts about this in the Operations Manager news groups and decided to outline the steps to achieve a report for Logical Disk % free space. The steps I outline will show you how to set up the Generic report for “Performance” to report on:
· Particular instances (or all instances) on a server or multiple servers.
· Particular instances (or all instances) on servers in a group (maybe in several groups, but you would have to play around with the settings)
· High level initial views and charts of performance with several drill-down reports that can be subscribed to or saved to favorites (several detail reports nested in this report).
· Known issues (OpsManager Reporting) with large numbers, but this is a percentile report so you shouldn’t run into the funny looking numbers in the details for samples.
· Be mindful of the date range. All too often you might be running a report with a time range of from 9 PM today to 12PM tomorrow, but then the day changes as you are configuring the report or running the report, therefore it’s best to switch to advanced in the time range and select -1 hour, day, week etc). A messed up date range may return no results and no errors, thus causing you to think there is no data.
Here are the steps (if you have verified or know that the “% Logical Disk Free Space 200X” collection rule is enabled and not overridden, then you can skip these verification steps: 1 -3):
1) In the authoring pane select rules and change the scope to Windows Server 200X Logical Disk. Searching for Logical should limit the scope as seen below:
2) Once you are scoped to those targets look for performance collection rules starting with “% Logical.” Once you do that you should see the rules listed:
3) Ensure that they are enabled (should be by default) and that they are no over rides applied to the servers you wish to report on.
4) Open the reporting pane.
5) Select “Microsoft Generic Report Library” from the reporting library and then select the report called “Performance”
6) Open the report “Performance” and you should see the following:
7) Change the “From” field to something in the past.
8) After you change the time range click on the button labeled “Change…” and you should see the following:
9) Click the button “New Chart” and give the chart a label. In my example I have two charts and they are described based on what they are collecting. Make your Objects box look similar to this:
As you can see from above I have customized each chart name to represent what is being reported on (to some degree). I could have put a company name in there, application name, etc. Label them however you want, but make sure it will make sense to whoever is viewing them. Below are detailed images of the criteria you will need to select to build the chart. For the first chart I only selected two servers and their instance of C:\. I could have added all C:\ objects (on all servers), but for the example I show just selected two. Be sure you have the collection rule specified and that the specific instances match (I am not 100% certain if you need to specify the instance when you are selecting the object).
· Criteria for % Logical Disk Free Space 2003 for C:\ object on SERVERA and SERVERB:
· Criteria for % Logical Disk Free Space 2003 for D:\ object on SERVERA and SERVERB:
· Criteria for % Logical Disk Space 2003 for all logical disk instances on all servers in the Management Server Computer Group and Root Management Server Computer Group (you can choose other groups, but keep them to computer groups):
· Run the report and you should get a report that looks something similar to this:
Now you can drill deep down to get full details on all of your logical disks. If you need these reports for groups of servers, or just certain instances for your entire agent managed servers, then be smart about setting these reports up. Consider the amount of data you are requesting (instances/objects/time range) before clicking “Run Report”.
