# Telegraf plugin: MongoDB
|
|
|
|
|

|
|
|
|
#### Configuration
|
|
|
|
|
|
|
|
|
|
```toml
|
|
|
|
|
[[inputs.mongodb]]
|
|
|
|
|
## An array of URI to gather stats about. Specify an ip or hostname
|
|
|
|
|
## with optional port add password. ie,
|
|
|
|
|
## mongodb://user:auth_key@10.10.3.30:27017,
|
|
|
|
|
## mongodb://10.10.3.33:18832,
|
|
|
|
|
## 10.0.0.1:10000, etc.
|
|
|
|
|
servers = ["127.0.0.1:27017"]
|

|
|
|
gather_perdb_stats = false
|
2016-04-15 15:10:30 +00:00
|
|
|
```
|
|
|
|
|
|
|
|
|
|
For authenticated mongodb istances use connection mongdb connection URI
|
|
|
|
|
|
|
|
|
|
```toml
|
|
|
|
|
[[inputs.mongodb]]
|
|
|
|
|
servers = ["mongodb://username:password@10.XX.XX.XX:27101/mydatabase?authSource=admin"]
|
|
|
|
|
```
|
|
|
|
|
This connection uri may be different based on your environement and mongodb
|
|
|
|
|
setup. If the user doesn't have the required privilege to execute serverStatus
|
|
|
|
|
command the you will get this error on telegraf
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
Error in input [mongodb]: not authorized on admin to execute command { serverStatus: 1, recordStats: 0 }
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
#### Description
|
|
|
|
|
|
|
|
|
|
The telegraf plugin collects mongodb stats exposed by serverStatus and few more
|
|
|
|
|
and create a single measurement containing values e.g.
|
|
|
|
|
* active_reads
|
|
|
|
|
* active_writes
|
|
|
|
|
* commands_per_sec
|
|
|
|
|
* deletes_per_sec
|
|
|
|
|
* flushes_per_sec
|
|
|
|
|
* getmores_per_sec
|
|
|
|
|
* inserts_per_sec
|
|
|
|
|
* net_in_bytes
|
|
|
|
|
* net_out_bytes
|
|
|
|
|
* open_connections
|
|
|
|
|
* percent_cache_dirty
|
|
|
|
|
* percent_cache_used
|
|
|
|
|
* queries_per_sec
|
|
|
|
|
* queued_reads
|
|
|
|
|
* queued_writes
|
|
|
|
|
* resident_megabytes
|
|
|
|
|
* updates_per_sec
|
|
|
|
|
* vsize_megabytes

|
|
|
|
|

|
If gather_db_stats is set to true, it will also collect per database stats exposed by db.stats()
|
|
|
|
|
creating another measurement called mongodb_db_stats and containing values:
|
|
|
|
|
* collections
|
|
|
|
|
* objects
|
|
|
|
|
* avg_obj_size
|
|
|
|
|
* data_size
|
|
|
|
|
* storage_size
|
|
|
|
|
* num_extents
|
|
|
|
|
* indexes
|
|
|
|
|
* index_size
|
|
|
|
|
* ok
