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 »
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 »
Another interesting announcement from the last re:Invent is that CloudWatch has added the ability to collect metrics from external resources (see a very interesting report AWS re:Invent 2023 – Cloud operations for today, tomorrow, and beyond (COP227)). That is, we can now create graphs and/or alerts not only from the default metrics of CloudWatch itself,… Read More »
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 »
We continue to develop our monitoring stack. See the first part – VictoriaMetrics: creating a Kubernetes monitoring stack with its own Helm chart. What do we want to do next: give access to developers so that they can set Silence for alerts themselves in Alertmanager to avoid spamming Slack, see Prometheus: Alertmanager Web UI alerts… 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… 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… 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… Read More »
