Grafana Loki: LogQL and Recoding Rules for metrics from AWS Load Balancer logs

24 February 2024
 

 I didn’t plan this post at all as I thought I would do it quickly, but it didn’t work out quickly, and I need to dig a little deeper into this topic. So, what we are talking about: we have AWS Load Balancers, logs from which are collected to Grafana Loki, see. Grafana Loki: collecting… Read More »

Karpenter: its monitoring, and Grafana dashboard for Kubernetes WorkerNodes

18 February 2024
 

 We have an AWS Elastic Kubernetes Service cluster with Karpenter which is responsible for EC2 auto-scaling, see AWS: Getting started with Karpenter for autoscaling in EKS, and its installation with Helm. In general, there are no problems with it so far, but in any case we need to monitor it. For its monitoring, Karpenter provides… Read More »

Grafana Loki: collecting AWS LoadBalancer logs from S3 with Promtail Lambda

25 November 2023
 

 Currently, we are able to collect our API Gateway logs from the CloudWatch Logs to Grafana Loki, see. Loki: collecting logs from CloudWatch Logs using Lambda Promtail. But in the process of migrating to Kubernetes, we have Application Load Balancers that can only write logs to S3, and we need to learn how to collect… Read More »

Grafana: values ​​from records in Loki logs, and dual-Y-axes panels in Grafana

19 August 2023
 

  We have a function in AWS Lambda, that is writing logs to CloudWatch Logs, from where with the lambda-promtail we are getting them to a Grafana Loki instance to use them in Grafana graphs. What the task is: in the logs, we have records about “Init duration” and “Max Memory Used” by Lambdas. There are… Read More »

Grafana Loki: performance optimization with Recording Rules, caching, and parallel queries

19 August 2023
 

  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… Read More »

VictoriaMetrics: deploying a Kubernetes monitoring stack

23 July 2023
 

  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… Read More »

VictoriaMetrics: an overview and its use instead of Prometheus

11 June 2023
 

  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… Read More »

Prometheus: GitHub Exporter – creating own exporter for GitHub API

11 June 2023
 

  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… Read More »

Loki: collecting logs from CloudWatch Logs using Lambda Promtail

20 May 2023
 

  Collecting logs in Grafana Loki with Kubernetes is very simple – we just launch Promtail in DaemonSet, configure it to read all data from /var/logs – and that’s it (in fact, we don’t specify anything at all – everything works out of the box from the Helm chart). But what about CloudWatch Logs? On my new… Read More »

GitLab: monitoring – Prometheus, metrics, and Grafana dashboard

12 March 2023
 

 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 »
