How can I keep only the last week of error logs? – 60East Technologies Support

As of the 4.0 release, AMPS does not provide a way to automatically delete error logs. However, you can use the log rotation action to rotate logs and create a file name specification that ensures that AMPS only keeps logs for the last 7 days.

Here's how to use these features together:

Create an action that rotates the log every day (typically, at midnight)
Specify a filename pattern for the log files that repeats every week

With these two configuration options in place, the effect is that AMPS will create a different log file each day, and reuse the same log file once every week.

The sample configuration below demonstrates how to do this:

...

<Actions>
  <Action>
    <On>
     <Module>amps-action-on-schedule</Module>
     <Options>
        <Every>00:00</Every>
     </Options>
    </On>
    <Do>
      <Module>amps-action-do-rotate-logs</Module>
      <Options>
        <Age>10s</Age>
      </Options>
    </Do>
  </Action>
</Actions>

<Logging>
  <Target>
      <Protocol>file</Protocol>
      <!-- Log files uses the day of the week in the format, so:
             AMPS-InstanceName-Friday.log  -->
      <FileName>./logs-dest/AMPS-InstanceName-%A.log</FileName>
      <Level>info</Level>
    </Target>
</Logging>

...

Notice that the configuration above doesn't set a RotationThreshold for the log. Instead, the log is allowed to grow until the Action rotates it once a day.
