Title
Multihost Agent host processes are missing -
Description
After created Multihost Agent, some host are not showing Processes information.
Please use the "Infrastructure" dashboard to check the HostProcess data for all host objects named as the host question (there could even be more than two), instead of using the VMware dashboard. The HostProcess data might have been merged into a different host object.
Under Infrastructure dashboard locate the two or three host with the same name, click on each one then click on "CPU Usage by Processs" and identify that some of those host have no Process metrics while one has it.
This is another check that can be done:1. Run the following query from Administration │ Tooling │ Script console, and type the following on the textbox that is on the left of "List Instances"!HostProcess : os.host.name = 'servername'2. Check whether the query return duplicate or triplicate host and check on each one the HostProcess objects and whether they are up to date.3. Check if there is a setup under Administration │ Agent │ Agent Status for either a WindowsAgent or Linux Agent for the host in question and if it's collecting data? -
Cause
The duplicate hosts were created because the vmId had changed (likely due to VMs migration) and the MultiHostProcessAgent kept submitting data to the old one. Therefore, the process data on the new host object could not be seeing.

Resolution
1). Go to Administration | Agents | Agent Status, and look for the Multihost Agent, please Deactivate the agent.
2).Go to Administration │ Tooling │ Script Console │ Script and click on Add button:
The following two scripts can be ran in order to determine whether there are Virtual machines with Null Vm Ids or duplicate Host that has the NumProcesses metrics:
delete_dup_host_with_null_vmId.groovyThe script is used to either find or delete duplicate hosts that do not have the vmId"delete_dup_host_with_process_data.groovy"The script is used to either find or delete duplicate hosts that have the numProcesses metric
Note: By default dryrun is set to true, change dryrun to false to truly delete the host.In order to apply above Workaround, please call QUEST support.
3). Then go to Administration | Management Server | Servers | Object CleanupWhile being on Object Cleanup, click on the left hand under "Host", then locate the host you want to delete (see if you have duplicates) on the right hand depending on the Type you choose and click "Delete Button.
4). Go back to Administration | Agents | Agent Status, and look for the Multihost Agent, please Activate the agent again.
Wait for 10 minutes and see if processes information is now being displayed.
