Camunda Run 7.22 Metrics

Camunda 7 Topics

I decided to go the other way. Since the http metrics of spring MVC conflict with Jersey (i.e. the uri is displayed correctly for Jersey, but is duplicated for mvc where uri=“UNKNOWN”), I decided to simply filter them.
Here are the dependencies pom file with dependencies:

    <properties>
        <java.version>17</java.version>
        <camunda.version>7.22.0</camunda.version>
        <spring.version>3.3.3</spring.version>
        <micrometer.version>1.13.6</micrometer.version>
    </properties>

                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

            <scope>provided</scope>
        </dependency>
    </dependencies>

Here is the fitration class:

package org.camunda.bpm.run.plugin.monitoring;

import io.micrometer.core.instrument.config.MeterFilter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MetricsConfig {

    @Bean
    public MeterFilter excludeAllExceptEngineRest() {
        return MeterFilter.deny(id -> {
            if (id.getName().startsWith("http.server.requests")) {
                return id.getTags().stream()
                        .noneMatch(tag -> tag.getKey().equals("uri") && tag.getValue().startsWith("/engine-rest/"));
            }
            return false;
        });
    }
}

Yaml settings for metrics:

management:
  endpoints:
    web:
      exposure:
        include: prometheus, metrics
  metrics:
    enable:
      jvm: true
      hikaricp: true
      process: true
      logback: false
      tomcat: false
      system: true
      jdbc: false
      http: true
    distribution:
      percentiles-histogram:
        http.server.requests: true
      percentiles:
        http.server.requests: 0.5, 0.9, 0.95, 0.99

I package everything in a jar file and put it as a plugin in the Docker image.
I use prometheus and Grafana for the display.
