APPLICATION LOGS

Reason and prerequisites

Errors occur because of:

• Machine Agent not installed
• Insights collectors are running and are collecting KPIs and table details
• Insights integration is triggered for replication KPIs like AppD metrics and records table details like AppD application events and Analytics events
• Metrics are sent via HTTP SDK, so if these are running, everything is OK
• Application events are still sent via Machine agent so if MA is installed or set up correctly, this error appears
• The only one option how to circumvent it is to turn off integration in /DVD/APPD_CC, but it also stops sending events and metrics

Solution

We recommend the customer to follow this guide.

Here can be found how to download and set up the recommended version of Machine Agent.
