A three node, three rack, one data center Cassandra cluster is running! It has a few configuration values that require IP addresses, yuck!
All the cluster software is up! What’s left?
- Install the Docker monitor for Prometheus (cAdvisor).
- Install BLEK.
- Cross-reference build scripts against written instructions.
- Throw it all away and rebuild from scratch.
- Make the github repository public.
Then, of course, there is actually using it, which is the end goal of this exercise. It’s been a great learning experience and I don’t regret spending the time on it, but it is all infrastructure, not anything personal.
Changed the VM size to 4 CPUs and 12GBs (and cleaned up the dashboard).
The metrics chop off because changing the VM configuration did very strange things to the time series, so I erased it all.
It’s still not bed time!
