# 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) #

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

\nUsage: ./check_storcenter -H host -U user -t type [-w warning] [-c critical]
\nRequirements: snmpwalk, tr\n
\nOptions: \t-H hostname\n\t\t-U user (to be defined in snmp settings on Storcenter)\n\t\t-t Type to check, see list below
\t\t-w Warning Threshold (optional)\n\t\t-c Critical Threshold (optional)\n
\nTypes: \t\tdisk -> Checks hard disks for their current status
\t\traid -> Checks the RAID status
\t\tcpu -> Check current CPU load (thresholds possible)
\t\tmem -> Check current memory (RAM) utilization (thresholds possible)
\t\tinfo -> Outputs some general information of the device"
