Introduction:

The following INFO message shows up every 30 secs in the MOM log.


[INFO] [pool-31-thread-2] [Manager.AppMap] 503 Service Unavailable

Question:

Why are these messages logged in the MOM Enterprise Manager Log every 30 secs?

 

 

Environment:
APM EM 10.xAPM Webview 10.x
Answer:

 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.
