Tell Me More
Did I pique your curiosity? Well good! PowerCLI 6.0 R1 has a new cmdlet ‘Get-DrmInfo’ which retrieves the DrmDumpInfo of each of the clusters within vCenter.
For those of you that are new to DrmDump, it is a log(s) of the actions that are both proposed and taken by the Distributed Resource Scheduler (DRS).
Now, to be fully transparent, this cmdlet only works with vSphere 6 and higher as this leverages the API version 6.0. If you try to run this in a 5.5 (or earlier) environment, you will receive an error:
How Do I Use It?
This cmdlet is quite simple to use. As a matter of fact, there are five parameters that may be used, but only one is actually required (-DestinationPath). The parameters of this cmdlet are:
- Cluster
- Start
- Finish
- NumFiles
- DestinationPath
If you do not specify a cluster, the cmdlet will run against each cluster in your vCenter. The cmdlet also accepts the cluster from the pipeline, meaning you can run a Get-Cluster | Get-DrmInfo and it will pipe the corresponding clusters to it.
The -Start and -Finish parameters allow you to specify specific dates to retrieve information from. For example, If I needed to check the DRM info and I wanted a window of 5 days ago, through today, I could specify it like this:
Get-Cluster Physical | Get-DrmInfo -Start 2015-05-30
If you want to get very specific you can add Time of Day on there as well:
Get-Cluster Physical | Get-DrmInfo -Start 2015-05-30T12:35:00
If I want between two specifc dates I would include the -Finish parameter:
Get-Cluster Physical | Get-DrmInfo -Start 2015-05-30 -Finish 2015-06-01
Using the -NumFiles parameter you can limit the number of files to the latest X number of dump files:
Get-DrmInfo -Cluster Physical -NumFiles 25
To export these files, you can add the -DestinationPath <destination folder> to the end of the command:
Get-Cluster Physical | Get-DrmInfo -Start 2015-05-30 -Finish 2015-06-01 -DestinationPath C:\Temp\
Conclusion
This cmdlet may not be the most-used but it does certainly have its set of use-cases. So next time you are needing to search through DRM logs, or need to troubleshoot the DRS actions, remember to use this cmdlet!
