cdist-type__prometheus_exporter(7)
==================================
NAME
----
cdist-type__prometheus_exporter - install some Prometheus exporters
DESCRIPTION
-----------
Install and configure some exporters to be used by the Prometheus monitoring system (https://prometheus.io/).
This type creates a daemontools-compatible service directory under /service/$__object_id.
Daemontools (or something compatible) must be installed (in particular, the command `svc` must be executable).
This type installs and builds the latest version from git, using go get. A recent version of golang as well
as build tools (make, g++, etc.) must be available.
REQUIRED PARAMETERS
-------------------
None
OPTIONAL PARAMETERS
-------------------
exporter
Which exporter to install and configure. Default: $__object_id.
Currently supported: node, blackbox, ceph
BOOLEAN PARAMETERS
------------------
add-consul-service
Add this exporter as a Consul service for automatic service discovery.
EXAMPLES
--------
.. code-block:: sh
__daemontools
__golang_from_vendor --version 1.9 # required for prometheus and many exporters
require="__daemontools __golang_from_vendor" __prometheus_exporter node
