Based on MongoDB exporter for prometheus.io, written in go (https://github.com/dcu/mongodb_exporter), but forked for full sharded support and structure changes.
The exporter is in beta/experimental state and field names are very likely to change and features may change or get removed!
- MongoDB Server Status metrics (cursors, operations, indexes, storage, etc)
- MongoDB Replica Set metrics (members, ping, replication lag, etc)
- MongoDB Replication Oplog metrics (size, length in time, etc)
- MongoDB Sharding metrics (shards, chunks, db/collections, balancer operations)
- MongoDB WiredTiger storage-engine metrics (cache, blockmanger, tickets, etc)
export GO_VERSION=1.5.1 # if you wish to use your system version
make
The exporter can be started by running the 'mongodb_exporter' binary that is created in the build step. The exporter will try to connect to 'mongodb://localhost:27017' (no auth) as default if no options are supplied.
It is recommended to define the following options:
- -mongodb.uri - The URI of the MongoDB port (default: mongodb://localhost:27017)
- -auth.user - The optional auth username (default: none)
- -auth.pass - The optional auth password (default: none)
- -web.listen-address - The listen address of the exporter (default: ":9001")
- -log_dir - The directory to write the log file (default: /tmp)
For more options see the help page with '-h' or '--help'
Point the process to any mongo port and it will detect if it is a mongos, replicaset member, or stand alone mongod and return the appropriate metrics for that type of node. This was done to preent the need to an exporter per type of process.
