Probably it can also be compatible with +# other Isilon or Celerra systems. It uses SSH to connect to Control Stations, then remotely executes +# /nas/sbin/server_stats and fetches and parses data from it. It supports gathering data both from active/active +# and active/passive Datamover configurations, ignoring offline or standby Datamovers. If all Datamovers are +# offline or absent, the plugin returns error. +# This plugin also automatically chooses Primary Control Station from the list by calling /nasmcd/sbin/getreason and +# /nasmcd/sbin/t2slot. +# +# Data is gathered from basic-std Statistics Group +# +# It's quite easy to comment out unneeded data to make graphs less overloaded or to add new statistics sources. + +##################################### +# Configuration # +##################################### + +# The plugin uses SSH to connect to Control Stations. It's possible to use 'nasadmin' user, but it would be better +# if you create read-only global user by Unisphere Client. The user should have only Operator role. +# I created "operator" user but due to the fact that Control Stations already had one internal "operator" user, +# the new one was called "operator1". So be careful. +# +# On munin-node side choose a user which will be used to connect through SSH. Generally user "munin" is ok. Then, +# execute "sudo su munin -s /bin/bash", "ssh-keygen" and "ssh-copy-id" to both Control Stations with newly created +# user. +# +# Make a link from /usr/share/munin/plugins/emc_vnx_dm_basic_stats to /etc/munin/plugins/emc_vnx_dm_basic_stats_, +# where is any arbitrary name of your storage system.
