vmware-exporter

This is a simple prometheus exporter that collects various metrics from a vCenter.

How to use

Run the exporter in a docker container (or start as a process) with all the settings necessary. Scrape it..

Exporter scrapes single vCenter host when /metcis path is used. Multiple vCenter hosts can be scraped using /probe, however these vCenter hosts must share credentials.

Settings

The exporter can be configured via command line options, environment variables, a yaml config file or a combination of all three. The environment variables set will be overwritten by the contents of the config file, which then will be overwritten by any command line option set at startup. The options available are:

key	description
-envflag.enable	Tells the exporter to use enviromnent flags in its configuration
-envflag.prefix	This allows to prefix the environment variables that will be used for configuration
-file	Path to a yaml configuration file that follows the structure of command line options
-http.address	The address and port the the exporter will bind to in host:port format (default: ":9169")
-log.format	Can be either json or logfmt (default: logfmt)
-log.level	One of debug,info,warn or error (default: debug) - Don't expect much..
-prim.maxRequests	Max concurent scrape requests (default: 20)
-disable.exporter.metrics	Disables exporter process metrics
-disable.exporter.target	Disables exporter default target - /metrics will only return exporter data - use /probe
-disable.default.collectors	Disables all collectors enabled by default
-collector.datacenter	Enables or disables DataCenter metrics collection (default: enabled)
-collector.cluster	Enables or disables Cluster metrics collection (default: enabled)
-collector.datastore	Enables or disables Datastore metrics collection (default: enabled)
-collector.host	Enables or disables Host metrics collection (default: enabled)
-collector.vm	Enables or disables Virtual Machine metrics collection (default: enabled)
-collector.esxcli.host.nic	Collects ESXi NIC firmware information using esxcli invoked through the vCenter (default: disabled)
-collector.esxcli.storage	Collects ESXi storage firmware information using esxcli invoked through the vCenter (default: disabled)

The esxcli collectors are a very specific use case that probably is not going to be needed by anyone. Left the code in here as an example on how custom information can be collected using esxcli command tool remotely via vCenter SOAP API
