Review the message log

The Logging tab provides access to connector message logs, allowing you to view status events, warnings, and errors generated by the connector. It displays recent log entries with severity levels and timestamps, and lets you control which types of messages are recorded and displayed to help monitor connector activity and troubleshoot issues.

The tab shows the 1,000 most recent messages recorded by the current connector service process. You can view older messages in the connector host machine's Windows Event Viewer under Applications and Services Logs > PI System Connector 3.

Each message in the log displays its severity level, time stamp, and the message itself. Internally, time stamps are stored as UTC times but display according to the browser's time zone settings.

You can specify the message recording level (that is, what types of messages are captured) as well as which messages appear on the screen.

Specify which messages to record

By default, connectors record only error and warning messages in the message log. To change the behavior to record more or fewer types of messages, select the Logging Level drop-down and choose an option.

View the message log

To specify which messages display in the message log, select the Log Level Filter drop-down list and select an option.

Changes to the message display options are not reflected across applications. Log levels set on the connector are not reflected on any brokers in the data stream chain.

Note: Changing the recording setting affects which messages are recorded, not which messages are displayed. For example, if you specify the recording setting Record error messages and the display setting Show error and warning messages, the log could contain older warning messages that were recorded prior to the change.

You can sort messages by severity level, date (including time stamp), and message text. To sort, click the column you want to sort by. To reverse the order, click the column again.

Filter the output

To filter messages by a specific string, type the string in the Filter Output field.

Pause Log Updates

To temporarily stop real-time updates of log messages to scroll through and review the log entries, select Pause Log Updates.

To restart live updates, select Pause Log Updates a second time.

Log Update Timer

Specifies how frequently the Logging tab refreshes to show new log messages. The default is set to 5 seconds.
