 emc_vnx_block_lun_perfdata - Plugin to monitor Block statistics of EMC VNX 5300

 Unified Storage Processors

=head1 DESCRIPTION

 The plugin monitors LUN of EMC Unified Storage FLARE SP's. Probably it can also

 from it. Obviously, it's easy to reconfigure plugin not to use Control Stations'

 and /nasmcd/sbin/t2slot.

 The plugin has been tested in the following Operating Environment (OE):

 old-style Clariion systems.

 First of all, be sure that statistics collection is turned on. You can do this

 by typing:

 navicli -h spa setstats -on

 Without these workarounds "Load" and "Queue Length" would not work.

 For example, assume your storage system is called "VNX5300".

 /etc/munin/plugin-conf.d/emc_vnx_block_lun_perfdata_VNX5300. For example:

 [emc_vnx_block_lun_perfdata_VNX5300]

 env.username operator1

 or:

 [emc_vnx_block_lun_perfdata_VNX5300]

 env.username operator1

 env.localcli /opt/Navisphere/bin/naviseccli

 env.sp_addr 192.168.0.3 192.168.0.4

 env.blockpw foobar

 user - SSH Client local user

 env.username - Remote user with Operator role for Block or File part

 env.cs_addr - Control Stations addresses for remote (indirect) access.

   variable is set, env.cs_addr is ignored, and local 'navicli' is used.

   Requires env.blockpw variable.

   Storage Processors, their addresses/hostnames are written here.

 env.blockpw - Password for connecting to Storage Processors

 from both SP's, but after we divide them independently by load of SPA and SPB.

 Anyway, in most AAA / ALUA cases the formula is correct.
