Is there a tool like Perfstat in Jmix 2 for performance monitoring?

Support

In the CUBA Platform, there was a tool called Perfstat that allowed us to monitor performance by showing how long methods like init, ready, and others took in seconds.

Is there a similar tool or feature available in Jmix 2 to track and analyze performance metrics like this? If not, what are the recommended approaches for performance monitoring in Jmix 2?

Thanks in advance for your help!

Hi.

There is a monitoring metrics for View and DataLoader lifecycle (Monitoring loader in screens · Issue #1704 · jmix-framework/jmix · GitHub).

You need to add Actuator and Prometheus dependencies

implementation 'org.springframework.boot:spring-boot-starter-actuator'
implementation 'io.micrometer:micrometer-registry-prometheus'

And expose endpoints via app property

management.endpoints.web.exposure.include=prometheus,health,info,metrics

Then go to /actuator/prometheus to check metrics or use some external UI to visualize.

Hi Ivan,

I am trying to use Actuator and Prometheus.
Since I have configured a webContextName “app”, the endpoint to check the metrics should be

http://localhost:8080/app/actuator/prometheus

But it does not work because it answers with HTTP 302 and then redirects me to the main application http://localhost:8080/app/

If i try without the context, http://localhost:8080/actuator/prometheus i get an HTTP 404 not found.

Can you help me to understand the problem?

Thank you anyway
Dario

Hi Dario,

  • What property do you use to change context? server.servlet.context-path?
  • Are you able to run any other actuator endpoints (e.g. /health)? And /actuator endpoint itself.
  • What is your Jmix version?

Hi Ivan,

I answer in order:

  • I am using cuba.webContextName = app
  • No, I am not able to run /health or /actuator
  • I am using CUBA 7.2 actually, I am realizing that I am in the wrong place.

Can you tell me is it possible to use actuator even with CUBA ?
Thank you,
Dario

Hi Dario,

Actuator is a String Boot feature.

In case of CUBA you can use perfstat logs:

  • You can find perfstat.log and perfstat-ui.log files in your deploy folder.
  • Or you can get access to them via application UI: Administration → Server Log and select log file.
