Hi Stuart,
Thanks to all the knowledge and guidance you have imparted on me, I
have decided to go with the below approach:
1. For the scenarios where aggregation of metrics is desired, I will
implement Prometheus Federation
2. For viewing the metrics of multiple Kubernetes clusters
individually, I will implement a Central Grafana dashboard with
individual AKS clusters added as datasources
3. For long term retention of the metrics or back up of the metrics, I
will use the option of *remote_write* to write all the metrics from
individual Kubernetes clusters to an InfluxDB instance. In case of any
data loss, I can have the new Prometheus server instance created and
have its *remote_read *pointed to this instance of InfluxDB - so that
the same Grafana dashboards with the same PromQL queries be used.
If a *remote_write* based back up is not desired due to any reasons,
then the simple option of taking disk snapshots of the Prometheus
server can be done ... although the snapshots have to be taken at a
higher frequency if the loss of the metrics data is to be minimized.
Does this sound like a plan?
That sounds perfectly reasonable.
I hope you get it all working and it does what you are hoping for :-)
