Environment

Watch4net/M&R - 7.x

Smarts - 10.1.x

Cause

MnR/Watch4net server is configured to use http/8080 however SM_CAS_SERVER attribute is configured in Smarts' runcmd_env.sh file hence output of smarts-edaa and alerts-edaa are redirected to CAS.

Resolution

As per the document Configuring SAM environment variables to support SSL SM_CAS_SERVER and SM_TOMCAT_SERVER are required while both Smarts and MnR are configured to use https/8443.

Remove both configured parameters, restart tomcat in Smarts and MnR would fix the issue of notification loading.
