Thanks Bryan,
Exploring the links you gave.
In the meantime, rolled out my own server to setup Prometheus and grafana.
Wrote a custom exporter to get counts for indic Wikipedia sites.

Check the above dashboard.
Will check if we can get the similar comparative graphs with wikistats2.
If this really goes well and community like to keep the dashboards for long time, will check with cloud vps team to host it.
Thanks. Shrini
