What to do when PRTG's ESX sensors show "Connection hangs. Check SSL on VMware server, then restart probe." message
When monitoring VMware ESX 3.5 servers with PRTG 7 we have seen situations where the HTTPS webserver of the ESX server crashes (i.e. the management interface is no longer accessible). In PRTG 7 all ESX sensors show a red alarm state as well as the message "Connection hangs. Check SSL on VMware server, then restart probe."
In order to revive the web server on the ESX server please perform the following steps:
- Start your SSH client (e.g. Putty) and log into the ESX server
- use the "root" account or another account with administrative rights
- restart the management service with the command:
Service mgmt-vmware restart
- Restart the PRTG probe that performs the actual monitoring oft he ESX sensors.
