We've run into another use case leveraging the Prometheus integration for Ops Manager to integrate with Grafana and noticed that there are some metrics missing compared to the Percona metrics exporter.
More specifically, the metrics from dbStats does not seem to be available for the Prometheus integrator, as well as these following metrics:
- Total DB size (sum of size of all individual DBs)
- Individual DB size history
- Total indexes
- Indexes per DB
- oplog size: mongodb_mongod_replset_oplog_size_bytes
- oplog length and replication lag - mongodb_mongod_replset_oplog_head_timestamp
- total cache evictions - mongodb_mongod_wiredtiger_cache_evicted_total
