Find Apache Tomcat and click its tile to open the integration.In your Grafana Cloud stack, click Connections in the left-hand menu.Install Apache Tomcat integration for Grafana Cloud Once deployed, the Grafana Agent should be able to reach the JMX Exporter’s exposed endpoint in order to scrape metrics. jmxUrl: service:jmx:rmi:///jndi/rmi://localhost:9010/jmxrmi The JMX URL for the exporter should be properly configured to match e.g. The JMX Exporter can be run with this Apache Tomcat JMX Exporter configuration file.įor more information on how to configure the JVM, please refer to the JMX Exporter documentation for further configuration.Īpache Tomcat exposes 9010 for JMX by default, but feel free to change the port to match your environment. To enable JMX collection, make sure your Tomcat instance is configured with the following CATALINA_OPTS: In order for the integration to properly work, you must set up the JMX Exporter for Prometheus to export metrics from Tomcat. This integration includes 4 useful alerts and 2 pre-built dashboards to help monitor and visualize Apache Tomcat metrics and logs. Metrics include virtual memory and cpu usage, traffic sent and received, total requests and processing time, threads, sessions and session processing time, and servlet requests and servlet processing time. This integration for Grafana Cloud allows users to collect metrics and logs for monitoring an Apache Tomcat instance. It also covers the Apache configuration that uses ExtendedStatus.Grafana Cloud Apache Tomcat integration for Grafana CloudĪpache Tomcat is an open source web server and servlet container that can run Java-based web applications. Side note: I've written an article that covers most aspects of monitoring Apache including granular traffic metrics: I guess you are using an Apache version lower than that. That said, ExtendedStatus is On by default from 2.3.6. The lines marked "(*)" are only available if ExtendedStatus is On.Īn example configuration that worked for me covering all the metrics: ExtendedStatus On The current hosts and requests being processed (*) The current percentage CPU used by each worker and in total by all workers combined (*) The time the server was started/restarted and the time it has been running forĪverages giving the number of requests per second, the number of bytes served per second and the average number of bytes per request (*) The status of each worker, the number of requests that worker has performed and the total number of bytes served by the worker (*)Ī total number of accesses and byte count served (*) Thanks a lot in advance.įrom what you have mentioned, it looks like you have not set the ExtendedStatus on.Ĭheck it out here. What am I missing here? How can I get the graphs for the rest of the panels? Any and all help is appreciated. PS - Both the Linode instances contain Debian GNU/Linux 9.8 (stretch) as their OS. This is the prometheus.yml config: #Apache Servers Among 7 panels in the entire dashboard (Current total kbytes sent, Current total apache accesses, Apache scoreboard statuses Apache worker statuses, Apache CPU load, Uptime and Apache Up/Down), I can see the grapf for Apache Up/Down. But when I import a grafana dashboard (ID - 3894) to visualize the data, I don't get any data. I've changed the -scrape_uri to \ and -telemetry.address to 127.0.0.1:9117 though I'm sure it wouldn't make any difference. I used the following document to install Apache exporter :ĮxecStart=/usr/local/bin/apache_exporter \ (PS - Prometheus and Grafana are running in a seperate Linode VM) My requirement is to monitor a Linode Virtual machine that contains Apache using Prometheus and Grafana.
