There are a few things that can lead to service discovery failures:
- Version of tools older than 10.1
- Tools not running
- Unmanaged tools that cannot be updated from vCenter
- Invalid guest mapping credentials
This dashboard helps with isolating each of these problems; let me show you how.
The dashboard has six useful sections:
1 - Select the vCenter you wish to troubleshoot. You can also view the collection state of the VC here before digging too deep. If there are problems with vCenter Server, you should address those first.
2 - This list provides all of the SDMP adapter instances; it makes it easy for you to configure excluded services for SDMP.
3 - SDMP Stats scoreboard shows some interesting stats based on the SDMP adapter instance selected in item 2.
4 - The VM Discovery Issues list shows the following:
- VMtools status
- VMtoools support
- Discovery method (Guest Alias or the default adapter instance credentials)
5 - VMs with No Service Discovery is a list of VMs for you to work from that have no initial discovery.
6 - Tools Status breakdowns provides overall number of VMs with tools running/not running and tools versions installed.
To install the dashboard, follow these steps:
1 - Download the zip file for the dashboard content here. (Click the download button)
2 - Extract the zip file to a suitable location.
3 - In vROps UI go to Content > Dashboards, import the SDMPTroubleshootingDashboard.json file.
4 - Now go to Content > Views, import the following:
- SDMP Discovery Failures
- SDMP No Success Tools Running
- SDMP No Success Tools Version
- SDMP VM No Services Discovered
5 - Finally, open the SDMPTroubleshooting.xml file in an editor (notepad is fine). Create a new metric config called SDMPScoreboard in Content > Manage Metric Config > ReskndMetric and paste the contents of the xml file into the new config (you should overwrite the default contents). Save it and you are finished!
