# Plugin to monitor basic statistics of EMC VNX 5300 Unified Datamovers #
######################################################################################################################
# Author: Evgeny Beysembaev <megabotva@gmail.com>
#####################################
# Description #
#####################################
# The plugin monitors basic statistics of EMC Unified Storage system Datamovers. 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_<NAME>,
# where <NAME> is any arbitrary name of your storage system. The plugin will return <NAME> in its answer
# as "host_name" field.
# Assume your storage system is called "VNX5300".
#
# Make a configuration file at /etc/munin/plugin-conf.d/emc_vnx_dm_basic_stats_VNX5300
#
# [emc_vnx_dm_basic_stats_VNX5300]
# user munin # SSH Client local user
# env.username operator1 # Remote user with Operator role
# env.cs_addr 192.168.1.1 192.168.1.2 # Control Stations addresses
# env.nas_servers server_2 server_3 # This is the default value and can be omitted
#####################################
# Errata #
#####################################
# Since LUN names can be long, the plugin can be affected by this bug: http://munin-monitoring.org/ticket/1352
