Telegraf Module
|
|
===============
|
|
The Telegraf module collects and sends statistics series to a Telegraf agent.
|
|
|
|
The Telegraf agent can buffer, aggregate, parse and process the data before
|
|
sending it to an output which can be InfluxDB, ElasticSearch and many more.
|
|
|
|
Currently the only way to send statistics to Telegraf from this module is to
|
|
use the socket listener. The module can send statistics over UDP, TCP or
|
|
a UNIX socket.
|
|
|
|
The Telegraf module was introduced in the 13.x *Mimic* release.
|
|
|
|

|
|
Enabling
|
|
--------
|
|
|
|
To enable the module, use the following command:
|
|
|
|
::
|
|
|
|
ceph mgr module enable telegraf
|
|
|
|
If you wish to subsequently disable the module, you can use the corresponding
|
|
*disable* command:
|
|
|
|
::
|
|
|
|
ceph mgr module disable telegraf
|
|
|
|
-------------
|
|
Configuration
|
|
-------------
|
|
|
|
For the telegraf module to send statistics to a Telegraf agent it is
|
|
required to configure the address to send the statistics to.
|
|
|
|
Set configuration values using the following command:
|
|
|
|
::
|
|
|
|
ceph telegraf config-set <key> <value>
|
|
|
|
|
|
The most important settings are ``address`` and ``interval``.
|
|
|
|
For example, a typical configuration might look like this:
|
|
|
|
::
|
|
|
|
ceph telegraf config-set address udp://:8094
|
|
ceph telegraf config-set interval 10
|
|
|
|
The default values for these configuration keys are:
|
|
|
|
- address: unixgram:///tmp/telegraf.sock
|
|
- interval: 15
|
|
|
|
----------------
|
|
Socket Listener
|
|
----------------
|
|
The module only supports sending data to Telegraf through the socket listener
|
|
of the Telegraf module using the Influx data format.
|
|
|
|
A typical Telegraf configuration might be
|
|
|
|
::
|
|
|
|
[[inputs.socket_listener]]
|
|
# service_address = "tcp://:8094"
|
|
# service_address = "tcp://127.0.0.1:http"
|
|
# service_address = "tcp4://:8094"
|
|
# service_address = "tcp6://:8094"
|
|
# service_address = "tcp6://[2001:db8::1]:8094"
|
|
service_address = "udp://:8094"
|
|
# service_address = "udp4://:8094"
|
|
# service_address = "udp6://:8094"
|
|
# service_address = "unix:///tmp/telegraf.sock"
|
|
# service_address = "unixgram:///tmp/telegraf.sock"
|
|
data_format = "influx"
|
|
|
|
In this case the `address` configuration option for the module would need to be set
|
|
to:
|
|
|
|
::
|
|
|
|
udp://:8094
|
|
|
|
|
|
Refer to the Telegraf documentation for more configuration options.
