MongoDB exporter
https://github.com/percona/mongodb_exporter/actions/workflows/go.yml/badge.svg?branch=main](https://github.com/percona/mongodb_exporter/actions/workflows/go.yml?query=branch%3Amain)  is moved to the release-0.1x branch. |
| If you ***ing migrating from the old version of the exporter - you can |
use flag --compatible-mode to expose metrics in the old metric names. This |
| will simplify migration to the new version for you. |
Flags
| Flag | Description | Example |
|---|---|---|
| -h, --help | Show context-sensitive help | |
| --compatible-mode | Exposes new metrics in the new and old format at the same time | |
| --discovering-mode | Enable autodiscover collections from databases which set in collstats-colls and indexstats-colls | |
| --mongodb.collstats-colls | List of comma separated databases.collections to get stats | --mongodb.collstats-colls=testdb.testcol1,testdb.testcol2 |
| --mongodb.direct-connect | Whether or not a direct connect should be made. Direct connections are not valid if multiple hosts are specified or an SRV URI is used | --mongodb.direct-connect=false |
| --mongodb.indexstats-colls | List of comma separated database.collections to get index stats | --mongodb.indexstats-colls=db1.col1,db1.col2 |
| --mongodb.uri | MongoDB connection URI ($MONGODB_URI) | --mongodb.uri=mongodb://user:pass@127.0.0.1:27017/admin?ssl=true |
| --mongodb.global-conn-pool | Use global connection pool instead of creating new connection for each http request. | |
| --web.listen-address | Address to listen on for web interface and telemetry | --web.listen-address=":9216" |
| --web.telemetry-path | Metrics expose path | --web.telemetry-path="/metrics" |
| --log.level | Only log messages with the given severity or above. Valid levels: [debug, info, warn, error] | --log.level="error" |
| --disable.diagnosticdata | Disable collecting metrics from getDiagnosticData | |
| --disable.replicasetstatus | Disable collecting metrics from replSetGetStatus | |
| --disable.dbstats | Disable collecting metrics from dbStats | |
| --version | Show version and exit |
Build the exporter
The build process uses the dockerized version of goreleaser so you don't need to install Go.
Just run make release and the new binaries will be generated under the build directory.
├── build │ ├── config.yaml │ ├── mongodb_exporter_7c73946_checksums.txt │ ├── mongodb_exporter-7c73946.darwin-amd64.tar.gz │ ├── mongodb_exporter-7c73946.linux-amd64.tar.gz │ ├── mongodb_exporter_darwin_amd64 │ │ └── mongodb_exporter <--- MacOS binary │ └── mongodb_exporter_linux_amd64 │ └── mongodb_exporter <--- Linux binary
Running the exporter
If you built the exporter using the method mentioned in the previous section, the generated binaries are in mongodb_exporter_linux_amd64/mongodb_exporter or mongodb_exporter_darwin_amd64/mongodb_exporter
Docker
A docker image is available on https://hub.docker.com/repository/docker/percona/mongodb_exporter.
Permissions
Connecting user should have sufficient rights to query needed stats:
{ "role":"clusterMonitor", "db":"admin" }, { "role":"read", "db":"local" }
More info about roles in MongoDB documentation.
Example
mongodb_exporter_linux_amd64/mongodb_exporter --mongodb.uri=mongodb://127.0.0.1:17001
Enabling collstats metrics gathering
--mongodb.collstats-colls receives a list of databases and collections to monitor using collstats.
Usage example: --mongodb.collstats-colls=database1.collection1,database2.collection2
mongodb_exporter_linux_amd64/mongodb_exporter --mongodb.uri=mongodb://127.0.0.1:17001 --mongodb.collstats-colls=db1.c1,db2.c2
Enabling compatibility mode.
When compatibility mode is enabled by the --compatible-mode, the exporter will expose all new metrics with the new naming and labeling schema and at the same time will expose metrics in the version 1 compatible way.
For example, if compatibility mode is enabled, the metric mongodb_ss_wt_log_log_bytes_written (new format)
# HELP mongodb_ss_wt_log_log_bytes_written serverStatus.wiredTiger.log. # TYPE mongodb_ss_wt_log_log_bytes_written untyped mongodb_ss_wt_log_log_bytes_written 2.6208e+06
will be also exposed as mongodb_mongod_wiredtiger_log_bytes_total with the unwritten label.
HELP mongodb_mongod_wiredtiger_log_bytes_total mongodb_mongod_wiredtiger_log_bytes_total # TYPE mongodb_mongod_wiredtiger_log_bytes_total untyped mongodb_mongod_wiredtiger_log_bytes_total{type="unwritten"} 2.6208e+06
Cluster role labels
The exporter sets some topology labels in all metrics. The labels are:
- cl_role: Cluster role according to this table:
| Server type | Label |
|---|---|
| mongos | mongos |
| regular instance (primary or secondary) | shardsvr |
| arbiter | shardsvr |
| standalone | (empty string) |
- cl_id: Cluster ID
- rs_nm: Replicaset name
- rs_state: Replicaset state is an integer from
getDiagnosticData()->replSetGetStatus.myState. Check the official documentation for details on replicaset status values.
