InfluxDB
|
||
========
|
||
|
||
You can export statistics to an ``InfluxDB`` server (time series server).
|
||
|
||
In Glances version 3.2.0 and higher, the way Glances exports stats to
|
||
InfluxDB changes. The following fields will be added as tags:
|
||
|
||
- key stats (for example *interface_name* for network, container *name* for docker...)
|
||
- hostname (shortname)
|
||
- tags
|
||
|
||
Glances InfluxDB data model:

||

InfluxDB (up to version 1.7.x)
|
||
------------------------------
|
||
|
||
The connection should be defined in the Glances configuration file as
|
||
following:
|
||
|
||
.. code-block:: ini
|
||
|
||
[influxdb]
|
||
host=localhost
|
||
port=8086
|
||
protocol=http
|
||
user=root
|
||
password=root
|
||
db=glances
|
||
# Prefix will be added for all measurement name
|
||
# Ex: prefix=foo
|
||
# => foo.cpu
|
||
# => foo.mem
|
||
# You can also use dynamic values
|
||
#prefix=foo
|
||
# Following tags will be added for all measurements
|
||
# You can also use dynamic values.
|
||
# Note: hostname is always added as a tag
|
||
#tags=foo:bar,spam:eggs,domain:`domainname`
|
||
|
||
and run Glances with:
|
||
|
||
.. code-block:: console
|
||
|
||
$ glances --export influxdb
|
||
|
||
Glances generates a lot of columns, e.g., if you have many running
|
||
Docker containers, so you should use the ``tsm1`` engine in the InfluxDB
|
||
configuration file (no limit on columns number).
|
||
|
||
Note: if you want to use SSL, please set 'protocol=https'.
|
||
|
||
|
||
InfluxDB v2 (from InfluxDB v1.8.x/Flux and InfluxDB v2.x)
|
||
---------------------------------------------------------
|
||
|
||
Note: The InfluxDB v2 client (https://pypi.org/project/influxdb-client/)
|
||
is only available for Python 3.6 or higher.
|
||
|
||
The connection should be defined in the Glances configuration file as
|
||
following:
|
||
|
||
.. code-block:: ini
|
||
|
||
[influxdb2]
|
||
host=localhost
|
||
port=8086
|
||
protocol=http
|
||
org=nicolargo
|
||
bucket=glances
|
||
token=EjFUTWe8U-MIseEAkaVIgVnej_TrnbdvEcRkaB1imstW7gapSqy6_6-8XD-yd51V0zUUpDy-kAdVD1purDLuxA==
|
||
# Set the interval between two exports (in seconds)
|
||
# If the interval is set to 0, the Glances refresh time is used (default behavor)
|
||
#interval=0
|
||
# Prefix will be added for all measurement name
|
||
# Ex: prefix=foo
|
||
# => foo.cpu
|
||
# => foo.mem
|
||
# You can also use dynamic values
|
||
#prefix=foo
|
||
# Following tags will be added for all measurements
|
||
# You can also use dynamic values.
|
||
# Note: hostname is always added as a tag
|
||
#tags=foo:bar,spam:eggs,domain:`domainname`
|
||
|
||
and run Glances with:
|
||
|
||
.. code-block:: console
|
||
|
||
$ glances --export influxdb2
|
||
|
||
Note: if you want to use SSL, please set 'protocol=https'.

Grafana
|
||
-------
|
||
|
||
For Grafana users, Glances provides a dedicated for `InfluxQL`_ or `Flux`_ InfluxDB datasource.
|
||
|
||
.. image:: ../_static/glances-influxdb.png
|
||
|
||
To use it, just import the file in your ``Grafana`` web interface.
