modifications for EMC Lenovo storcenter

Hi,

I modified some OID for best compatibility with EMC LENOVO StorCenter version.

Hope it helps!

# Script: check_storcenter #
# Author: Claudio Kuenzler www.claudiokuenzler.com #
# Description: Plugin for Nagios (and forks) to check an EMC/Iomega #
# Storcenter device with SNMP (v3). #
# License: GPLv2 #
# History: #
# 20111010 Created plugin (types: disk, raid, cpu, mem) #
# 20111011 Added info type #
# 20111013.0 Corrected uptime (but device returns strange value?) #
# 20111013.1 Corrected uptime (using hrSystemUptime.0 now) #
# 20111020 Disk type now doesnt return CRITICAL anymore if disks missing #
# 20111031 Using vqeU in mem type (if response comes with kB string) #
# 20120425 Add port as variable #

# Usage: ./check_storcenter -H host -P port -U user -t type [-w warning] [-c critical]

nUsage: ./check_storcenterv2 -H host -P port -U user -p password -t type [-w warning] [-c critical]
nRequirements: snmpwalk, trn
nOptions: t-H hostnamentt-U user (to be defined in snmp settings on Storcenter)ntt-t Type to check, see list below
tt-P snmp portn
tt-w Warning Threshold (optional)ntt-c Critical Threshold (optional)n
nTypes: ttdisk -> Checks hard disks for their current status
ttraid -> Checks the RAID status
ttcpu -> Check current CPU load (thresholds possible)
tthrProcessorLoad -> Check current CPU Load with OID = hrProcessorLoad
ttmem -> Check current memory (RAM) utilization (thresholds possible)
ttinfo -> Outputs some general information of the device”
