 emc_vnx_file_stats - Plugin to monitor Basic, NFSv3 and NFSv4 statistics of 

 EMC VNX 5300 Unified Storage system's Datamovers

 The plugin monitors basic statistics of EMC Unified Storage system Datamovers 

 and NFS statistics of EMC VNX5300 Unified Storage system. 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. 

 This plugin also automatically chooses Primary Control Station from the list by

  calling '/nasmcd/sbin/getreason' and '/nasmcd/sbin/t2slot'.

  * basic-std Statistics Group - Basic Statistics of Datamovers (eg. CPU, Memory

  etc.)

 It's quite easy to comment out unneeded data to make graphs less overloaded or

 to add new statistics sources.

=head1 LIST OF GRAPHS

 These are Basic Datamover Graphs.

 Graph category CPU:

	EMC VNX 5300 Datamover CPU Util %

 Graph category Network:

	EMC VNX 5300 Datamover Network bytes over all interfaces

	EMC VNX 5300 Datamover Storage bytes over all interfaces

 Graph category Memory:

	EMC VNX 5300 Datamover Memory

	EMC VNX 5300 File Buffer Cache

	EMC VNX 5300 FileResolve

 These are NFS (v3,v4) Graphs.

 Graph category NFS:

	EMC VNX 5300 NFSv3 Calls per second

	EMC VNX 5300 NFSv3 uSeconds per call

	EMC VNX 5300 NFSv3 Op %

	EMC VNX 5300 NFSv4 Calls per second

	EMC VNX 5300 NFSv4 uSeconds per call

	EMC VNX 5300 NFSv4 Op %

	EMC VNX 5300 NFS Client Ops/s

	EMC VNX 5300 NFS Client B/s

	EMC VNX 5300 NFS Client Avg uSec/call

 The plugin has been written for being compatible with EMC VNX5300 Storage 

 system, as this is the only EMC storage which i have.

 By the way, i am pretty sure it can also work with other VNX1 storages, like

 VNX5100 and VNX5500.

 About VNX2 series, i don't know whether the plugin will be able to work with 

 them. Maybe it would need some corrections in command-line backend. The same

 situation is with other EMC systems, so i encourage you to try and fix the 

 plugin. 

 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. After that, copy .bash_profile from /home/nasadmin to a newly created

 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 

 Make a link from /usr/share/munin/plugins/emc_vnx_file_stats to 

 /etc/munin/plugins/. If you want to get NFS statistics, name the link as 

 "emc_vnx_file_nfs_stats_<NAME>", otherwise to get Basic Datamover statistics

 you have to name it "emc_vnx_file_basicdm_stats_<NAME>", where <NAME> is any

 arbitrary name of your storage system. The plugin will return <NAME> in its 

 answer as "host_name" field.

 Make a configuration file at 

 /etc/munin/plugin-conf.d/emc_vnx_file_stats_VNX5300

 user munin				

 env.username operator1				

 env.cs_addr 192.168.1.1 192.168.1.2		

 env.nas_servers server_2 server_3		

 Where: 

 user - SSH Client local user

 env.username - Remote user with Operator role

 env.cs_addr - Control Stations addresses

 env.nas_servers - This is the default value and can be omitted
