esxcli_env_ - Plugin to monitor ESXi host temperature or power via esxcli.
This plugin should be linked as esxi_env_temp or esxi_env_power.
Configuration variables (/etc/munin/plugin-conf.d/):
Munin native:
host_name - Name of you ESXi host as defined in munin.conf
timeout - Plugin specific timeout
Plugin specific:
env.esxi_host - (REQUIRED) hostname/ip esxcli connect to
env.esxi_user - (REQUIRED) ESXi username to connect
env.esxi_password - (REQUIRED) password for user given above
env.cache_file - path to cache file (we do not want two or more sequential reconnections to ESXi host)
env.cache_max_age - if cache file is an older than this, we will fetch new data from ESXi host
env.warning - warning limit
env.critical - critical limit
env.margin_warning - warning limit for temperature margin values
env.margin_critical - critical limit for temperature margin values
Please be aware that Munin has a 10 second default timeout on plugins. On some hosts esxcli can take longer
than that, but you could set timeout in plugin config.
