Viewing Log Data for Deployed Apps
CloudHub 2.0 provides access to log data that includes deployment messages and events for each replica and Mule runtime engine logs.
For more advanced searching and log management, you can use Anypoint Monitoring (requires Titanium subscription). See Anypoint Monitoring Overview.
CloudHub 2.0 stores up to 100 MB of log data per config, or up to 30 days, whichever limit is reached first.
Logs are stored in the same region to which the corresponding cluster is deployed.
| CloudHub 2.0 stores log data in Universal Time (UTC); however, the console displays the log using your computer’s local time zone. |
View Logs
To view logs for applications deployed to a private space:
-
From Anypoint Platform, select Runtime Manager > Applications.
-
Click the app name.
-
In the navigation menu, click Logs.
The logs page displays all logs for all replicas for the selected config, with the latest messages at the bottom. The config represents the deployment since the last update.
When you update an application, a new configuration is created. In this case, the logs page might be empty. The page streams log messages as they occur, unless the last deployed section is closed. Logs from before the last updated time appear in a drop-down containing previous deployments.
Each message includes the severity, time (relative and absolute), and replica name.
To view logs for a different config, click the Config drop-down list and select the config. The config label indicates the relative time of deployment, such as 10 hours ago.
Search Logs
To search within the currently displayed config:
-
From Anypoint Platform, select Runtime Manager > Applications.
-
Click the app name.
-
In the navigation menu, click Logs.
-
Enter the search term in the Search field.
The results display includes the currently selected config, replica, and log levels.
You can search with queries. For more information, see Log Search Query Syntax.
Filter Logs
To filter the log results:
-
From Anypoint Platform, select Runtime Manager > Applications.

Click the Config drop-down menu and select the config to view.

Filter log by replica
In a log message for the desired replica, click the name of the replica.
Only the logs for the selected replica appear.
To clear the replica filter and display logs for all replicas, click the X button for the selected replica.
