It is strongly advised to monitor memory usage of the exporter. That also mean that you have to side the limits properly to avoid Kubernetes CrashloopBackoff because of Java OOM. Thats why exporters are as close as possible from Cassandra nodes. I feel that JMX exporter is reporting metrics correctly but its not connected to Prometheus correctly. As discussed in issue prometheus111, it is not intended that the JMX exporter extracts generic JVM metrics when running as a separate process. Important: scraping outside the statefulset can multiply x10 the scraping time. Grafana v5.0 JMX exporter v0.3.0 Cassandra v3.11 Dashboard revisions. Response of metrics page (IP-215:9090/metrics) is here WebCassandra dashboard for Prometheus JXM exporter. import io.

These metrics can be queried via JMX or pushed to external monitoring systems using a number of built in and third party reporter plugins. This tutorial describes how to use Prometheus and Java Management Extensions (JMX) to monitor a Java application running on a Google Kubernetes Engine cluster. # The job name is added as a label `job=` to any timeseries scraped from this config. Cassandra Operating Metrics Edit Monitoring Metrics in Cassandra are managed using the Dropwizard Metrics library. Scrape_interval: 15s # Set the scrape interval to every 15 seconds. i can reach to Prometheus gui on prometheus.yaml file is set to following. I am running Prometheus on node x215 (different node than kafka broker). I tried installing Prometheus as blogs explains but running into issues i find launching Prometheus easy with docker container as docker run -p 9090:9090 -v /etc/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus I want to connect jmx exporter with Prometheus and eventually to grafana for visualization as described here
Hi All this question is in continuation of question hereīy now i have single node kafka broker running on node x214 and its reporting metrics using jmx exporter on port 7071 curl -s localhost:7071 | grep -i kafka
