Log Levels

The log level represents the minimum level of information written to Express Server's error and access logs.

There are eight levels:

0. Emergencies
1. Alerts
2. Critical Conditions
3. Errors
4. Warnings
5. Notices
6. Informational Messages
7. Debug Messages
8. All

If the log level is set at "3 - Errors", then logging will include emergencies, alerts, critical conditions and errors. If the log level is set at "1 - Alerts", then logging will include only emergencies and alerts.

The log files are stored in <Express Server installation directory>/ImageServer/var/log.

Setting the Log Level

1. Open the Express Server Manager (see Accessing the Express Server Manager).
2. Click Settings on the top navigation bar, then select the Basic tab on the left-hand navigation and click Edit.
3. Choose a level from the Log level drop-down menu, then click Save.
4. If you have no further settings to edit, click Publish.

Remember that clicking Save in the workspace only temporarily saves your changes until you click Publish or Discard. Clicking Publish sends all edits on all the configuration pages to the live Express Server. Clicking Discard overwrites all pages of the workspace with the current live configuration.

By default the log level is set at "5 - Notices", a level that includes emergencies, alerts, critical conditions, errors, warnings and notices.
