This issue occurs due to start up timeout for StatsMonitor Service. The startup DB health check completed in a given time, occasionally, the IO might be too slow to start the service.
This issue is resolved in vCenter Server 6.5 U3f and vCenter Server 6.7 U3You can download newer versions from here if needed: Download VMware vSphere You can download product patches from here if needed: VMware Product Patches
To workaround this issue, take a snapshot of VCSA without memory: Take SSH to VCSA using root login.Modify statsmonitor service config for vMon to set higher startup timeout by running this command: sed -i '/StartTimeout/d' /etc/vmware/vmware-vmon/svcCfgfiles/statsmonitor.jsonsed -i '/ApiHealthFile/a "StartTimeout": 600,' /etc/vmware/vmware-vmon/svcCfgfiles/statsmonitor.json Run the kill -HUP $(cat /var/run/vmon.pid) command.Stop and start statsmonitor service explicitly by running this command: /usr/lib/vmware-vmon/vmon-cli -k statsmonitor /usr/lib/vmware-vmon/vmon-cli -i statsmonitor reboot the VCSA and check after 10-15 mins and the Statsmonitor Service should start up automatically.
