Deep dives into specific back-end technologies which allow for the extension of Qlik to fit the needs of the enterprise.
This is an extension of the original post outlining the SMTP appender. Another very relevant, but non-obvious use case for this appender is to help alert Administrators of Qlik Sense when an App’s object breaches the specified Telemetry thresholds. If Telemetry in Qlik Sense is new to you, do head over to the Enterprise Architecture’s GitHub Repository on Telemetry.
After configuring thresholds which are appropriate for your environment / SLA requirements, if you wanted to extend this functionality further, you can leverage the stream of Telemetry data which is logged by the Engine which comes to the Qlik Sense Repository Service to trigger an email alert (or any other appender type):
The config example is provided here. Like with reload failure alerting, do review the config examples in the reload failures section of the Repo for examples of how to configure for email servers which require authentication.
Notes:
LocalLogConfig.xml
file to C:\ProgramData\Qlik\Sense\RepositorySince this stream of Engine data is not logged to the Repository logs, but is streamed, the structure is as follows:
