DPA VM Option - what does it monitor?

Our DBA team uses both DPA and SQL Sentry to monitor all things database.  We had an issue kind of creep up that we noticed in DPA and I was asked the question "What does DPA use for metrics in VMWare?"  What does Disk Red mean?

I was trying to find the answer on Solarwinds site but got stuck in the Buy Me Now loop.  Is there a document or information on what Disk red means in DPA? We also run the VM Option in DPA and I was wondering what that uses/looks at in VMWare. 

I usually just update DPA and let the DBA team roll with the software.

Thanks!

  • The DPA VMWare metrics are polled from the VM connection to the VMWare MOB or Management Object Browser. 

    https://vdc-repo.vmware.com/vmwb-repository/dcr-public/f1c3b41b-ead5-4d47-aca4-33298d5a4fcf/778a00f3-a9b6-42f4-8f22-7216733f5f03/doc/PG_Appx_Using_MOB.20.2.html

    If you dig some into DPA's file paths you will find a link in the XML files that are defaulted to this path. It's deep in the structure. 

    C:\Solarwinds\DPA\iwc\tomcat\webapps\iwc\WEB-INF\classes\resources\metrics\vsphere\vsphere-metrics-definitions.xml

    If you look in that you will see what use to be a link to part of the VMWare documentation. Those pages have moved some over the years so the links are not as direct now. But, here is an example. 

    Take this part that has <information page> and it use to be part of the page you need to read in VMWare API docs to know where and how that data is fetched. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.monitoring.doc/GUID-F8EF57D2-0B27-4972-BE73-F985EE3B94A3.html

    The pages have moved on VMWare documentation over the years but, in general if you look at the API page above you should find the related metrics and how they are gathered in the MOB.
