If you’re only interested in a certain panel, head over directly to the corresponding subsection.Now that you have a better idea of what’s going on in our application, let’s install the different tools needed.This is exactly why we write those articles and build those dashboards : to help you reach the maximum efficiency of what those tools have to offer.Here’s a closer view of what rounded gauges in our panel.Congratulations! Back to our dashboard.In order to retrieve those metrics, we are going to perform PromQL queries on our Prometheus instance.Click on ‘Save and Test’ and make sure that your datasource is working properly.If you have access to Prometheus’s web console, it means that everything went just fine.In our case, the bash script has a very tiny lifespan and it doesn’t expose any HTTP instance for Prometheus.Horizontal gauges are one of the latest additions of Grafana v6.2.With a monitoring dashboard, you can simply go back in time and see which process was causing the issue.In this case, running a top command would give you zero information as it would be too late for you to catch who’s causing performance issues on your system.When it comes to process monitoring for Unix systems, you have multiple options.As you can tell, this script gathers all metrics for our processes but it only runs one iteration.Create a script file, give it some rights and navigate to it.Also, we are going to monitor our memory usage with this panel so the query is slightly different.Now let’s say that you want the performance of a certain process in your system : let’s take Prometheus itself for example.To perform this task, you have multiple candidates.As a reminder, our script will perform a ps aux command, parse the result, transform it and send it to the Pushgateway via the syntax we described before.Until then, have fun, as always.Now that you have extracted the deb file, grafana should run as a service on your instance.The syntax is very easy to use as we are going to demonstrate it with our panels.As done before, run a simple wget command to get it.By externalizing process monitoring, you can analyze what’s causing the outage without accessing the machine.Now that we have an overview of everything that we are going to learn, and without further due, let’s have an introduction on what’s currently existing for Unix systems.This command is widely used among sysadmins and is probably the first command run when a performance bottleneck is detected on a system (if you can access it of course!
You can access this information using kube_pod_container_status_restarts_total or kube_pod_container_status_restarts_total{namespace="<namespace>"} for a specific namespace.In addition to the default metrics, our Prometheus instance is scraping data from kube-apiserver, kube-scheduler, kube-controller-manager, etcd, kube-dns/coredns, and kube-proxy, as well as all the metrics exported by "kube-state-metrics".
