=head1 NAME
emc_vnx_file_stats - Plugin to monitor Basic, NFSv3 and NFSv4 statistics of
EMC VNX 5300 Unified Storage system's Datamovers

=head1 DESCRIPTION
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.
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'.
At the moment data is gathered from the following statistics sources:
* nfs.v3.op - Tons of timings about NFSv3 RPC calls
* nfs.v4.op - Tons of timings about NFSv4 RPC calls
* nfs.client - Here new Client addresses are rescanned and added automatically.
* 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.
The plugin has been tested in the following Operating Environment (OE):
File Version T7.1.76.4
Block Revision 05.32.000.5.215
=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 NFS Client B/s
EMC VNX 5300 NFS Client Avg uSec/call
=head1 COMPATIBILITY
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.
=head1 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. After that, copy .bash_profile from /home/nasadmin to a newly created
/home/operator1
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_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.
For example, assume your storage system is called "VNX5300".
Make a configuration file at
/etc/munin/plugin-conf.d/emc_vnx_file_stats_VNX5300
[emc_vnx_file_*]
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
