If Uptime Infrastructure Monitor has difficulty communicating with agents that have had their IP address or hostname changed, follow these steps to debug the issue:
- Confirm that the Uptime Infrastructure Monitor hostname of the agent matches the new hostname or IP address.
- Try adding the full domain name to the hostname if it is not already entered.
- Restart the Uptime Infrastructure Monitor data collector.
- Confirm that the monitoring station is able to properly resolve the new IP / hostname by running the following commands from the monitoring station:
> nslookup <hostname>
> ping <IP returned from the above>
