We have "Setup Managed Prometheus for AKS via Terraform", however, that setup alone will not provide windows metrics from AKS clsuter to Azure managed Grafana. We have to addtionaly, setup Windows exporter and couple of additional configurations to make it work as decribed in the official Microsoft docs here. Let's look at step by step how to enable windows metrics for AKS with managed prometheus.
Expected outcome is getting metrics such as shown below to managed grafana and visualizing them.
Based on "Enable Prometheus Data Scraping for Bitnami Redis Cluster Deployed on AKS with Managed Prometheus" and "Enable Prometheus Data Scraping for Bitnami Redis Standalone Deployed on AKS with Managed Prometheus" discussed in the previous posts, let's look at using the managed prometheus data source in Azure Manged Grafana and how to setup monitoring for AKS deployed Bitnami Redis, with few examples.
The expectation is to have charts as shown below.
We have discussed "Enable Prometheus Data Scraping for Bitnami Redis Cluster Deployed on AKS with Managed Prometheus" in the previous post. Similar way we can setup Prometheus data scraping for standalone redis deployments on AKS as well. Here are the steps.
The expectaion is to have the metrics sidecar run with the standalone redis master and replica pods as shown below and setup a service monitor so that redis metrics data is made available in Azure managed grafana via managed prometheus on AKS.
Importing state to terraform may be required when a resource is manually created previously, now need to be managed by terraform. Or it can be a situation where you Move code from one repo to another for reorganizing purpose and now you need to refer to exesting resource in Azure and map it to new repo terraform code. The state import can be performed with terraform import command manually. However, performin such task manually targeting production environments is not ideal and kind of impossible, in autmated deployment implementations. In this post let's discuss, a Azure pipeline task that can be used to perform the state imports in a rerunnable way.
Such task toupdate terraform state in Azure pipline should be placed between the terraform init and terraform plan tasks as shown below.
"Setup Redis Cluster with JSON and Search Modules on AKS with Binami Redis Using Custom Image" and "Setup Managed Prometheus for AKS via Terraform" are explained in the previous posts. To enable setting up monitoring and alerting for the Redis Custer deployed in AKS the first step is to enable Prometheus data scraping in the Redis cluster we deployed on AKS. Let's look at the steps in this post.
The expectation is to have redis metrices available to Azure managed grafana via the managed prometheus in AKS as shown below.
We have discussed "Deploying Azure Managed Grafana with Terraform" ealier. Now that we have managed grafana available in Azure for the AKS clsuters we can enable managed prometheus. You can setup prometheus on your own in AKS however it is beter to use Azure managed prometheus with AKS as it would leverage the capabilities of Azure monitor and Azure managed grafana to better monitoring and alerting abilities and avoid additional work required to setup full monitoring and observability on your own in an AKS cluster. The offcial documentation is here for leaning more information on the setup.
As we discusssed in "Setup Redis Cluster with JSON and Search Modules on AKS with Binami Redis Using Custom Image" the cluster deployemnt does not allow the redis to be accessed outside of AKS/kubernetes. To allow local development with redis we have to deploy redis standalone on AKS. Ideally the standalone should be setup in development environment and clsuter mode should be setup in QA and production environments. Let's look at how to setup redis standalone with json and search modules using custom image we built in "Build Custom Docker Images with Redis Json and Search Module Support for deploying Bitnami Redis Cluster and Standalone in AKS".
"Setup Redis Cluster with JSON and Search Modules on AKS with Binami Redis Using Custom Image" is explained in the prevous post. We can use redis insight to connect to redis cluster on AKS to explore data and add or update data. Let's look at how we can setup redis insight on AKS in this post.
The expectation is to have redis insight connected to redis clsuter on aks as shown below.
