QUESTION

Is there a possibility to add custom spring boot metrics tags at runtime?

Asked 2021-Jun-14 at 19:52

I'm using Spring Boot with micrometer-registry-prometheus, trying to store custom tags from http headers, security context, etc.

So I found MeterFilter iterface and tried to use it to store the data I need.

But MeterFilter method works after request is completed, so at that point I don't have any information about request.

Seems like the case is pretty common, is there any possibility to achieve it?

If you're using Spring MVC you can define a bean that implements WebMvcTagsProvider to take complete control over the tags that are added to metrics for request-response exchanges. Alternatively, you can define a bean that implements WebMvcTagsContributor to add to the default tags. Similarly, if you're using Spring WebFlux you can define beans that implements WebFluxTagsProvider and WebFluxTagsContributor to take complete control over the tags and contribute additional tags respectively.

QUESTION

When running Prometheus, all my endpoints start returning 404

Asked 2021-Jun-02 at 16:01

I have SpringBoot app that works just fine, my endpoints return proper responses when I hit my API endpoints using Postman.

Same with my Actuators. They are working fine.

I also added spring dependencies micrometer-core and micrometer-registry-prometheus which added to my Actuators new path `/prometheus'. This path also works just fine and returns metrics.

Since I wanted to see the graphing, I downloaded standalone Prometheus app (so no docker image) from official site (zip file) and unziped it.

Inside, there is prometheus.exe and prometheus.yaml file.

Even without modifying this yaml file at all, as soon as I double click on prometheus.exe to start it (which starts it properly), all of my endpoints stop returning 200 OK and start returning 404 Not Found responses.

Then I modified it to add my job name and path like

Your app is exposing endpoints on the same port of Prometheus 9090. Change your spring boot application to expose the endpoint at 8080 or any other port except 9090. Then scrape your app at that port.

io.micrometer contains disk space metrics (io.micrometer.core.instrument.binder.jvm.DiskSpaceMetrics) but it doesn't seems to be enabled by default. There are no metric data. How do i enable this metric that it can be used by prometheus?

ANSWER

Metrics about disk space are exposed as part of the health endpoint, which is provided by Spring Boot Actuator (dependency: org.springframework.boot:spring-boot-starter-actuator).

The health endpoint can be enabled as follows in the application.properties file (by default, it should be enabled):

Yeah we certainly never anticipated this. We probably have to think about releasing a separate "non-shaded" artifact for teams.

Feel free to open an issue and we'll look into it. Of course if you can contribute, nothing like it.

For the time being can you try this and let me know how it goes. I think you should be able to create your own JAR locally and use maven-shade to remove micrometer from the karate fat-jar. Then use that dependency in your project. I can't think of anything else.

Do you explicitly need version 2.12.2 of jackson-dataformat-xml?

Problem

jackson-dataformat-xml:2.12.2 is not compatible with jackson dependencies 2.11.4. Spring Boot overwrites Jackson dependencies that are not specified other way in dependencies block or in dependencyManagement.

Solution

If you don't need 2.12.2 then just define the jackson-dataformat-xml as following:

I'm not sure what do you man by cached. Meters in Micrometer are created from and held in a MeterRegistry. Also, a meter is uniquely identified by its combination of name and tags so if you request a meter with the same name and tags, you should get back the same instance:
