We are trying to figure out which monitoring options will be suitable for our environment.
We have two clusters in GCP and we installed Istio (with Helm) in both of them. We are also using Workload Identity and Stackdriver Monitoring.
Now, we would like to create dashboards (or charts) for kubernetes objects (such as, deployments, containers, cronjobs, services, etc.) and want to set alerts on them. So can anyone suggest free monitoring options to achieve these all? We don't want to go with any third party paid software.
Thank you in advance.
If you are using GCP GKE then default stack driver logging & monitoring is best option.
It's free if you are using GCP service and using stack driver monitoring you can monitoring and creat respective dashboards as per need.
For alerts, you can use the GCP Uptime check option available in monitoring itself which sends the email. For call alerts, you may have to use some custom or third applications.
