Mongodbatlas exporter for Prometheus

Archived: NO LONGER MAINTAINED

Atlas released a prometheus integration that provides much more reliable metrics without having to circumvent API rate limits.

See Introducing MongoDB’s Prometheus Monitoring Integration.

Limitations

• Exporter supports up to 30 processes (mongod and mongos)

number of process calculation:
1 sharded cluster with 3 shards = 3x3 shards mongod processes + 3x3 mongos processes + 3x1 config mongod processes = 21
1 non-sharded cluster (replica set) = 3x1 mongod processes

• Minimal scrape interval should be 1m
