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:
+---------------+-----------------------+-----------------------+
| Measurement | Fields | Tags |
+===============+=======================+=======================+
| cpu | user | hostname |
| | system | |
| | iowait... | |
+---------------+-----------------------+-----------------------+
| network | read_bytes | hostname |
| | write_bytes | disk_name |
| | time_since_update... | |
|  | | |
+---------------+-----------------------+-----------------------+
| diskio | rx | hostname |
| | tx | interface_name |
| | time_since_update... | |
|  | | |
+---------------+-----------------------+-----------------------+
| docker | cpu_percent | hostname |
| | memory_usage... | name |
+---------------+-----------------------+-----------------------+
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
# Followings 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==
# Prefix will be added for all measurement name
# Ex: prefix=foo
# => foo.cpu
# => foo.mem
# You can also use dynamic values
#prefix=foo
# Followings 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.

To use it, just import the file in your ``Grafana`` web interface.
