# MongoDB Input Plugin
|
|
|
|
### Configuration:
|
|
|
|
```toml
|
|
[[inputs.mongodb]]
|
|
## An array of URLs of the form:
|
|
## "mongodb://" [user ":" pass "@"] host [ ":" port]
|
|
## For example:
|
|
## mongodb://user:auth_key@10.10.3.30:27017,
|
|
## mongodb://10.10.3.33:18832,
|
|
servers = ["mongodb://127.0.0.1:27017"]
|
|
|
|
## When true, collect per database stats
|
|
# gather_perdb_stats = false
|
|
## When true, collect per collection stats
|
|
# gather_col_stats = false
|
|
## List of db where collections stats are collected
|
|
## If empty, all db are concerned
|
|
# col_stats_dbs = ["local"]
|
|
|
|
## Optional TLS Config
|
|
# tls_ca = "/etc/telegraf/ca.pem"
|
|
# tls_cert = "/etc/telegraf/cert.pem"
|
|
# tls_key = "/etc/telegraf/key.pem"
|
|
## Use TLS but skip chain & host verification
|
|
# insecure_skip_verify = false
|
|
```
|
|
|
|
#### Permissions:
|
|
|
|
If your MongoDB instance has access control enabled you will need to connect
|
|
as a user with sufficient rights.
|
|
|
|
With MongoDB 3.4 and higher, the `clusterMonitor` role can be used. In
|
|
version 3.2 you may also need these additional permissions:
|
|
```
|
|
> db.grantRolesToUser("user", [{role: "read", actions: "find", db: "local"}])
|
|
```
|
|
|
|
If the user is missing required privileges you may see an error in the
|
|
Telegraf logs similar to:
|
|
```
|
|
Error in input [mongodb]: not authorized on admin to execute command { serverStatus: 1, recordStats: 0 }
|
|
```
|
|
|
|
Some permission related errors are logged at debug level, you can check these
|
|
messages by setting `debug = true` in the agent section of the configuration or
|
|
by running Telegraf with the `--debug` argument.
