If you have installed up.time for the first time, or changed the hostname of your Monitoring Station and receive a message 'up.time Data Collector' is unavailable in the Monitoring Station GUI. This is likely the result of a mismatch between the hostname up.time is trying to use to connect 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:

• Edit the uptime.conf file in the up.time installation directory.
• Modify the httpContext and monitorHost fields to point to the correct hostname for your server.
• Restart the up.time data collector: Starting (or restarting ) and Stopping up.time
