If you’re only interested in a certain panel, head over directly to the corresponding subsection.Here’s a closer view of what rounded gauges in our panel.For now, we are going to focus on the CPU usage of our processes as it can be easily mirrored for memory usage.With those panels, we are going to track two metrics :In order to retrieve those metrics, we are going to perform PromQL queries on our Prometheus instance.Similarly what you found find on InfluxDB instances with InfluxQL (or IFQL), PromQL queries can aggregate data using functions such as the sum, the average and the standard deviation.The syntax is very easy to use as we are going to demonstrate it with our panels.In order to retrieve the current overall CPU usage, we are going to use.At a given moment in time, our overall CPU usage is simply the sum of individual usages.Not much work to do for average CPU usage, you are simply going to use the.Horizontal gauges are one of the latest additions of Grafana v6.2.Our goal with this panel is to expose the top 10 most consuming processes of our system.Similarly to what we did before, we are going to define thresholds in order to be informed when a process is consuming too many resources.Vertical gauges are very similar to horizontal gauges, we only need to tweak the.Also, we are going to monitor our memory usage with this panel so the query is slightly different.Line graphs have been in Grafana for a long time and this is the panel that we are going to use to have an historical view of how our processes have evolved over time.This graph can be particularly handy when :When it comes to troubleshooting exploration, it would honestly need a whole article (especially with the recent Grafana Loki addition).You can arrange them the way you want or simply take some inspiration from the one we built.Real time data is interesting to see — but the real value comes when you are able.In this bonus section, we are not going to use the ‘Explore’ function (maybe in another article? As the number of parts of the system increases, it's essential to have to have a monitoring approach that is dynamic and scalable to match the system being built.A popular open source solution is called Prometheus.

A service that hosts Grafana, Loki, and Prometheus at scale. Task. ).The top command is already pretty readable, but there is a command that makes everything even more readable than that:Htop provides the same set of functionalities (CPU, memory, uptime..) as top but in a colorful and pleasant way.By externalizing process monitoring, you can analyze what’s causing the outage without accessing the machine.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.You would have to dig into kernel logs to see what has been killed.With a monitoring dashboard, you can simply go back in time and see which process was causing the issue.Now that you know why we want to build this dashboard, let’s have a look at the.Before having a look at the architecture that we are going to use, we want to use a solution that is:Those are the points we will keep in mind throughout this tutorial.The detailed architecture we are going to use today is this one:Our architecture makes use of four different components:For those who are quite familiar with Prometheus, you already know that Prometheus scraps metrics exposed by HTTP instances and stores them.In our case, the bash script has a very tiny lifespan and it doesn’t expose any HTTP instance for Prometheus.This is why we have to use the Pushgateway ; designed for.Now that you have a better idea of what’s going on in our application, let’s install the different tools needed.Now that you have the archive, extract it, and run the executable available in the pushgateway folder.As described in the ‘Getting Started’ section of Prometheus’s website, head over to.Now that you have the archive, extract it, and navigate into the main folder:Exit vi, and finally run the prometheus executable in the folder.Prometheus should start when launching the final prometheus command.
