If you have installed up.time for the first time, or changed the hostname of your Monitoring Station and receive an 'up.time Data Collector' message is unavailable in the Monitoring Station web interface. This is likely the result of a mismatch between the hostname up.time is trying to use to contact the Core/Data-collector and where the service is actually running.
This can be resolved by updating the uptime.conf with the correct hostname for your server:
\n- Edit the uptime.conf file in the uptime installation directory.
- Modify the httpContext and monitorHost fields to point to the correct hostname for your server.
- Restart the up.time data collector: Starting and Stopping up.time
