In the Prometheus: running Pushgateway on Kubernetes with Helm and Terraform post I wrote about how to add Pushgateway to Prometheus, which allows using the Push model instead of Pull, that is, an Exporter can send metrics directly to the database instead of waiting for Prometheus or VMAgent to come to it. With VictoriaMetrics, it’s… Read More »
So, we have Loki installed from the chart in simple-scale mode, see Grafana Loki: architecture and running in Kubernetes with AWS S3 storage and boltdb-shipper. Loki is runnings on an AWS Elastic Kubernetes Service cluster, installed with Loki Helm chart, AWS S3 is used as a long-term store, and BoltDB Shipper is used to work… Read More »
Now we have VictoriaMetrics + Grafana on a regular EC2 instance, launched with Docker Compose, see the VictoriaMetrics: an overview and its use instead of Prometheus. It was kind of a Proof of Concept, and it’s time to launch it “in an adult way” – in Kubernetes and all the configurations stored in a GitHub… Read More »
I’ve heard a lot about VictoriaMetrics for a long time, and finally, it’s time to try it out. So, in a nutshell – VictoriaMetrics is “Prometheus on steroids” and is fully compatible with it – can use its configuration files, exporters, PromQL, etc. So for me who has always used Prometheus, the first question was… Read More »
Recently, I got a new interesting task – to build a dashboard in Grafana that would display the status of our development process and its performance, that is, the efficiency of our DevOps processes. This is necessary because we are trying to build “true continuous deployment” so that the code automatically enters Production, and we… Read More »
We have a lot of AWS Lambda functions in the project, and developers want to be able to send metrics to our Prometheus to add their own alerts and graphs in Grafana. For this, the functions use the Prometheus library, which allows these metrics to be created (see Prometheus: Building a Custom Prometheus Exporter in… Read More »
So, let’s continue our journey with migrating GitLab to Kubernetes. See previous parts: GitLab: Components, Architecture, Infrastructure, and Launching from the Helm Chart in Minikube GitLab: Helm chart of values, dependencies, and deployment in Kubernetes with AWS S3 GitLab: міграція даних з GitLab cloud та процес backup-restore у self-hosted версії в Kubernetes In general, everything is working,… Read More »
Prometheus has many ready-to-use exporters, but sometimes you may need to collect your own metrics. For this, Prometheus provides client libraries that we can use to generate metrics with the necessary labels. Such an exporter can be included directly in the code of your application, or it can be run as a separate service that will poll one… Read More »
The very useful thing is to monitor how efficiently the cluster is being used, especially if applications are deployed by developers who do not delve into requests much and set inflated values ”in reserve”. A reserve, of course, is needed – but simply requesting resources is a bad idea. For example, you have a WorkerNode… Read More »
The blackbox-exporter is an exporter that can monitor various endpoints – URLs on the Internet, your LoadBalancers in AWS, or Services in a Kubernetes cluster, such as MySQL or PostgreSQL databases. Blackbox Exporter can give you HTTP response time statistics, response codes, information on SSL certificates, etc. What are we going to do in this… Read More »
