Issue/Introduction

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?

 

 

Environment

APM EM 10.xAPM Webview 10.x

Resolution

 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.
