Monitoring Fluree

[Tr3yb0]

How do you monitor a deployed Fluree cluster? Are there logs or metrics you can turn on to monitor performance, uptime, etc. (trying to think how i'd set up monitoring like AWS Aurora cloudwatch has but for fluree) and hopefully hook into those metrics to do disaster recovery or autoscaling

We have currently have an /nw-state endpoint to get information about the running network.
You would want to have health checks on the instances as well for memory, network, storage alerts as well. If an instance of a cluster was not responsive or in alarm, you can remove it and add a new instance to a cluster and raft consensus can get it back up to date.
We also have our native implementation of fuel, which is included as a response header on all queries (and as metadata on accepted transactions), actually clarifies the computational cost of queries/transactions. You can even set maximum fuel-limits on transactions/queries to guarantee that they experience an upper-limit threshold. In this regard, fuel is a great way to measure query expense and optimize accordingly in order to improve complex filters/aggregates on your queries
