Alert: Unexpected error initializing OID tree; check logs
If you see a message similar to the following in the apache logs, follow the step below:
Check the apache http.conf file to see what is listed for the Proxy settings and compare those against the settings in the uptime.conf file.
ProxyPass /uptime http://localhost.localdomain:9996/uptime retry=0 ProxyPassReverse /uptime http://localhost.localdomain:9996/uptime |
httpContext=http://localhost:9999 monitorHost=localhost |
In this case, the localhost.localdomain was causing the issue. By changing the setting to localhost, the error went away
