Environment

vmware probe 6.72

Resolution

By default VMware limits the "vpxd.stats.maxQueryMetrics" to 64. This will cause the probe metric
collection to fail if a Resource Pool/vAPP or a cluster has more than 64 VMs or a Datastore has more
than 64 VMs or disks. You will see an error message such as: “Failed to execute single perf query for
entity ……. Follow VMware KB 2107096 to resolve.”
Solution :
Follow the instructions in the VMware Knowledge Base article "Performance charts are empty" #
2107096 (https://kb.vmware.com/selfservice/microsites/search.do?
language=en_US&cmd=displayKC&externalId=2107096), on how to increase the "vpxd.stats.
maxQueryMetrics." Increase the "vpxd.stats.maxQueryMetrics" to more than the maximum number
of VMs that you have in a resource pool, cluster. Similarly, increase the "vpxd.stats.
maxQueryMetrics" to more than the maximum number of VMs/Disks that you have in a Datastore.
