This information helps you to monitor and administer Alfresco Media Management.

If you are backing up and restoring Media Management, use the standard Alfresco guidance: Back up and restore.

Monitoring Media Management

You can monitor the flow of media events from the Alfresco repository through ActiveMQ and system logs.

1. Check the health of ActiveMQ, particularly that the following events are occurring:

   • Topics > alfresco.health.contentservices shows that heartbeats are being sent
   • Queues > alfresco.transform.request.image, alfresco.transform.reply.image, alfresco.transform.request.video, and alfresco.transform.reply.video are showing messages enqueuing and dequeuing ActiveMQ provides a web console:

   Code copied to clipboard.
    http://localhost:8161/admin/
   

   where localhost is the name of the Alfresco server.

   You can also check the ActiveMQ log, which is located in activemq/data/activemq.log where activemq is the name of directory where you installed ActiveMQ.

   By default, subscribers are set to Active Durable Topic Subscribers to ensure that if ActiveMQ fails, messages are not lost.

   Note: For technical reasons, Topics > Messages Dequeued never decrements. Do not monitor this queue.

2. Check the content services node log to monitor what is being transformed:

   • Port 8889 is reserved for the content services node. http://localhost:8889/healthcheck shows the last transformation after startup (but before any transformations). You should see:

     Code copied to clipboard.
       {"FFmpeg":{"healthy":true},"ImageMagick":{"healthy":true},"deadlocks":{"healthy":true}}
     

     and after a transformation request:

     Code copied to clipboard.
       {"FFmpeg":{"healthy":true,"message":"lastRequest: \"6075f46f-de9c-4232-aa78-d3ed1280a371\""},"ImageMagick":{"healthy":true},"deadlocks":{"healthy":true}}
     

   • Check the log, which is located in remote-node/logs/content-services-node.log, where remote-node is the name of directory that you unzipped when you installed Media Management.
   • You can change the log level of the content services node in the remote-node/config.yml file.

3. Check alfresco.log, after setting the log level to debug, for any errors.

4. Use the log4j.properties.sample file to add loggers to your tomcat/webapps/alfresco/WEB-INF/classes/alfresco/module/org_alfresco_mm_repo/log4j.properties file.

   A log4j.properties.sample file is provided in the Media Management installation zip. This file contains loggers that you can add to your Alfresco log4j.properties file to trace and debug your Media Management workflow.

Admin Tools for Media Management

Administrators can view information about transformations and add publishing channels in the Admin Tools option of the Share menu bar.

1. Select Admin Tools on the Share toolbar, to see a list of tools on the left of the page.
2. The Tools > Application section lists the themes available. Media Management provides a black background (a dark theme) for Share. For more see Using an Alfresco dark site theme for more information.
3. The Content Publishing > Channel Manager section lists the channels that are configured for users to publish media (for example, CloudFront). Use this guidance to add a new publishing channel: Configuring a CloudFront publishing channel.
4. The Transformations section lists the installed transformers and their status. Select Transformer FFmpeg to see information on whether the transformer is available, and the version of FFmpeg that is installed with the options configured.
