The following INFO message shows up every 30 secs in the MOM log.
[INFO] [pool-31-thread-2] [Manager.AppMap] 503 Service Unavailable
Why are these messages logged in the MOM Enterprise Manager Log every 30 secs?
This is due to using the Webview non-SSL port (8081) REST API not being enabled. Enabling the REST API resolves the problem.
1. Open the MOM_HOME/config/IntroscopeEnterpriseManager.properties.
2. Uncomment the following property
introscope.enterprisemanager.webserver.jetty.configurationFile=em-jetty-config.xml
3. Enable the REST API by setting the following property.
introscope.public.restapi.enabled=true
4. Restart the EM.
Note: If using ETC (Enterprise Team Center) or ATC (APM Team Center), you will need to restart them as well.
