    VCSA 6.5 statsmonitor service stops unexpectedly

      Hi,

       

      from time to time the VCSA 6.5e statsmonitor service stops unexpectedly. This breaks the ability to backup VCSA data via PowerCLI script. Another consequence is that there are no CPU/Memory/Database Statistics collected in VCSA management backend.

       

      vRealize LogInsight Log excerpt is attached for the considered timeframe and filtered by "statsmonitor". I cannot tell from this log why it tried to add this service, tried to start it and then failed.

      So the stop occurred on June, 13th for the last time. It remained stopped since then. Before June, 13th, I realized it and fixed it on June, 8th.

       

      I see this problem occurring one one of our VCSA 6.5 instances but not on the other ones.

       

      Does anyone else see this behavior or any idea what's wrong?

          From the events, it shows the below file does not exists or cannot read

           

          Error: [Errno 2] No such file or directory: '/var/vmware/applmgmt/statsmonitor_health.xml

           

          can you enable a putty session or login to shell of VCSA

           

          cd /var/vmware/applmgmt/

           

          execute the "ls -lah" command and check if the file exists statsmonitor_health.xml and also check the size of the file

           

          Please copy the output of ls -lah

           

          Thanks,

          MS

            Yes, I saw this message, too. When the service is started, the file is existing.

             

            ls -lah currently reports (service is running):

              I updated VCSA to 6.5u1 last Friday morning. Right after update and reboot, statsmonitor service was running and data was displayed in FAMI. However, it somewhen stopped until Friday in the evening. VSA backup failed since then.

               

              Please note: 6.5u1 adds alarms for 6.5-new services like statsmonitor (please see: VMware vCenter Server 6.5 Update 1 Release Notes ). So we can configure it to send an email, if the service stops.

                I had to restart VCSA 6.5u1 last Friday. Statsmonitor did not get started automatically after this reboot (I triggered it via FAMI backend), it was stopped during the weekend. Log Insight tells me:

                Again and again and again. Now, after manually starting statsmonitor service, the file statsMonitor.xml is existing in /etc/vmware/statsmonitor.

                  I started seeing this issue since upgrading to 6.5U1. I also had a similar issue with the vmware-content-library, but I found the fix for that.

                   

                  This is more of an annoyance though, this shouldn't have any direct performance implications. But I would love to get it fixed, right along with the update health issue.

                    I just installed Patch a after 6.5.0u1 and rebooted. Service "vmware-statsmonitor" is stopped after reboot and /var/vmware/applmgmt/statsmonitor_health.xml is missing.

                    After manually starting vmware-statsmonitor the file statsmonitor_health.xml is existing (369 byte). this is reproduceable after every reboot.

                      This is a known issue with vSphere 6.5 and should be fixed in the next release.

                      Please take a snapshot of VCSA without memory and run through the below steps .

                      1. Take SSH to VCSA using root login.

                      2.  # Modify statsmonitor service config for vMon to set higher startup timeout:

                      sed -i '/StartTimeout/d' /etc/vmware/vmware-vmon/svcCfgfiles/statsmonitor.json
                      sed -i '/ApiHealthFile/a "StartTimeout": 600,' /etc/vmware/vmware-vmon/svcCfgfiles/statsmonitor.json

                       

                      3.  kill -HUP $(cat /var/run/vmon.pid)

                       

                      4.  # Stop and start statsmonitor service explicitly.

                        /usr/lib/vmware-vmon/vmon-cli -k statsmonitor
                        /usr/lib/vmware-vmon/vmon-cli -i statsmonitor

                       

                      Now reboot the VCSA and check after 10-15 mins and the Statsmonitor Service should start up automatically.

                        I can confirm that the same issue exists with the following appliance but slightly different, same exact error except this time once the appliance is booted one can manually start the monitoring service. It just doesn't start automatically even though it is set for auto start..

                         

                        Type: vCenter Server with an embedded Platform Services Controller

                        Product: VMware vCenter Server Appliance

                        Version: 6.7.0.21000 Build number 11726888

                         

                        The error I get upon boot and auto start attempt for VMware Appliance Monitoring Service is below:

                         

                        <statsmonitor> Service api-health command's stderr: Error getting service health. Error: Failed to read health xml file: /var/vmware/applmgmt/statsmonitor_health.xml. Error: [Errno 2] No such file or directory: '/var/vmware/applmgmt/statsmonitor_health.xml'
