This document describes how to view and manage app information from Spring Boot Actuator in Apps Manager.


The Apps Manager integration with Spring Boot Actuator requires:

View Build and Git Information for Your App

To view the data that your app sends to its /info Actuator endpoint, select the Settings tab:


In the upper right of the app page, Apps Manager also displays the SHA of your app code repository from the latest build:


View App Health

To view the health-check data that your app sends to its /health Actuator endpoints:

  1. Select the Overview tab.

  2. Click an instance under the Instances section:


View Thread Dump

To trigger and view a thread dump from your app to its /dump Actuator endpoint:

  1. Select the Threads tab.

  2. Click Refresh.

You can click each thread to expand and view its details. You can also modify which threads appear on the page using the Instance and Show dropdowns.

View Request Traces

To retrieve and view tracing information from the /trace Actuator endpoint of your app:

  1. Select the Trace tab.

  2. Click Refresh.

This page displays the last 100 requests from your app. You can click each individual request to expand and view its trace details. You can modify which requests appear on the page using the Instance dropdown.

Manage Log Levels for Apps Mapped to External Routes

Spring Boot apps include loggers for many provided and user components of the app. You can set the log level for each logger in Apps Manager.

To view the Configure Logging Levels screen:

  1. Select the Logs tab.

  2. Click Configure Logging Levels.

alt-text=Configure Logging Levels

Apps Manager displays the default log level for each logger in gray.


You can modify the log level for a logger by clicking the desired level in the logger row, as shown in the following image. Whenever you set a log level, the following happens:

  • The log level displays in blue to indicate that it is user-configured.
  • Each child namespace of the logger inherits the log level.

    Note You can manually set any of the child loggers to override this inheritance.

alt-text=Set log level

All of the loggers with user-configured logging levels go to the top of the list.


You can reset log levels by clicking the white dot displayed on the current log level.

alt-text=Reset logs

You can also filter which loggers you see using the Filter Loggers text box.

alt-text=Filter logs

Troubleshoot Spring Boot Actuator Integration

This section describes how to troubleshoot common issues with the integration of Apps Manager and Spring Boot Actuator.

/cloudfoundryapplication Failed Request


You see the following failed request message in your app logs:

Could not find resource for relative : /cloudfoundryapplication of full path:


Apps Manager uses the /cloudfoundryapplication endpoint as the root for Spring Boot Actuator integrations. It calls this endpoint for an app when you view the app in the Apps Manager UI, regardless of whether you have configured Spring Boot Actuator endpoints for Apps Manager.


If you are not using the Spring Boot Actuator integrations for Apps Manager, you can ignore this failed request message.
