==================================
|
||||
|
||||
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.
|
||||

||||
