From YouTube: Self monitoring of GitLab with Prometheus and Grafana in 5 Minutes

Description

Many customers wonder how they can easily get an overview about their GitLab Self-Managed instance installed via the Omnibus Package. In this Video I am showing how to leverage the internal Prometheus and Grafana of GitLab in order to get a instant overview about your GitLab Instance Metrics.

If you want want to dive right in please see below:

Further Info:
For those who wonder - the /-/metrics endpoint did NOT show up since my Client IP Address was not whitelisted in the config of GitLab. In order to access the raw-metrics endpoint you need to whitelist it according to: https://docs.gitlab.com/ee/administration/monitoring/ip_allowlist.html

I switched my GitLab Instances accidentally from gitops.art to gitops.fun. Basically everything is running on gitlab.gitops.art :)!

A

So hello and welcome thanks for diving in in five minutes, gitlab monitoring um uh with me: Alex, that's um Solutions, I tagged here at kitlab, so I'm going to show you um really nutshell how you can quickly enable um grafana um to display the metrics which are kind of already present on your gitlab package installation, so we're focusing on the Omnibus package installation to get these metrics here very quickly. Why I'm doing that I see a lot of customers like not having any visibility? What's going on and then I'm thinking when things get slow?

A

What could it be so very good just like enabling some visibility um at the very beginning, I don't get that so it's very easy. Basically, what I've done is um I have installed um kitlab the kitlab package on Google Cloud, just following the official documentation here, basically um yeah and then um editing the config file so basically spawn an instance use Ubuntu and the package install according to um the documentation.

A

um uh So like most people um and then just like um switching to my instance here um and configuring some things. So basically, what we're going to do is like the main config file and we're going to configure um this accordingly.

A

um Very simple, so all you need to do in here is you get a public IP address from Google? um Basically, we use let and crypt here um just to obtain a valid certificate, so I highly recommend just do that. um Get a domain basically enter your email address here, um get a domain in my uh in my case, that's githubs.art right and just register on your DNS provider.

A

The public IP address um with um yeah with your provider that that points there was and then during the Ruby completely you will get a certificate very nice right. um So what you want to do is to enable grafana, so there's the section already in but grafana isn't enabled per default. So basically just like go to that section. Search grafana enable it um set admin password.

A

So in my case, that's gitlab one explanation mark um and then just like set disable login form to false, because otherwise there will be only like gitlab as so um be available. Okay, so then after you've set that basically you just like do a sudo, a gitlab control reconfigure and that's going to like um restart all the services and make that new configuration available. So, for the sake of the video I've done that before and you'll see that and then well, what you can do is you can go to your instance.

A

What you see here in my case, that's kid ops.fun right if I look at the um certificate again. So basically you see that is issue bar, let's encrypt, so everything is fine and yeah. The only thing I did I just like added a group here that we have something to see. So the nice thing is like you don't have to do anything more. So you just like go to githubs.art right and you go to the grafana endpoint, which is basically you see here. It's just like a dash and then grafana um and on your instance.

A

Even there issues the dash Matrix, which isn't accessible yet. But so basically here is my grafana endpoint, um which is enabled by the configuration which I've shown you and you have some. You have some dashboards in here so per default. Even we add the Omnibus dashboards and then you see like the metrics for the most important services, and that can be very, very helpful right.

A

You can create your custom dashboard on that, but it will really help you to just like look into issues and if you assume that there is an issue on the application side, it's very easy to determine whether on the response times maybe went upright whether there is more queuing um or basically I'm, just like um yeah yeah, just like the general performance or up time, which you have um from the instance. So very good is that service platform metrics here we see kind of like the service availability.

A

um You see that here in general, which is very good, because this is a new instance and then, of course, um the overall overview which we're having here. um So where was it yeah the overview which just gives you a nice dashboard about that so make use of it? It's there um so for now we're doing a lot of like efforts into the monitoring space, so a lot of more Integrations will come, but for now this is a very, very good option for you um to leverage um so I encourage you um to do that.
