Usage: ./check_snmp_load.pl [-v] -H <host> -C <snmp_community>
[-2] | (-l login -x passwd [-X pass -L <authp>,<privp>])
[-p <port>] -w <warn level> -c <crit level>
-T=[stand|netsl|netsc|as400|cisco|cata|nsc|fg|bc|nokia|hp|lp]
[-f] [-t <timeout>] [-V]
-v, --verbose
print extra debugging information
-h, --help
print this help message
-H, --hostname=HOST
name or IP address of host to check
-C, --community=COMMUNITY NAME
community name for the host's SNMP agent (implies v1 protocol)
-2, --v2c
Use snmp v2c
-l, --login=LOGIN ; -x, --passwd=PASSWD
Login and auth password for snmpv3 authentication
If no priv password exists, implies AuthNoPriv
-X, --privpass=PASSWD
Priv password for snmpv3 (AuthPriv protocol)
-L, --protocols=<authproto>,<privproto>
<authproto> : Authentication protocol (md5|sha : default
md5)
<privproto> : Priv protocole (des|aes : default des)
-P, --port=PORT
SNMP port (Default 161)
-w, --warn=INTEGER | INT,INT,INT
1 value check : warning level for cpu in percent (on one minute)
3 value check : comma separated level for load or cpu for
1min, 5min, 15min
-c, --crit=INTEGER | INT,INT,INT
critical level for cpu in percent (on one minute)
1 value check : critical level for cpu in percent (on one
minute)
3 value check : comma separated level for load or cpu for
1min, 5min, 15min
-T, --type=stand|netsl|netsc|as400|cisco|bc|nokia|hp|lp
CPU check :
stand : standard MIBII (works with Windows),
can handle multiple CPU.
netsl : linux load provided by Net SNMP
netsc : cpu usage given by net-snmp (100-idle)
as400 : as400 CPU usage
cisco : Cisco CPU usage
cata : Cisco catalyst CPU usage
nsc : NetScreen CPU usage
fg : Fortigate CPU usage
bc : Bluecoat CPU usage
nokia : Nokia CPU usage
hp : HP procurve switch CPU usage
lp : Linkproof CPU usage
-f, --perfparse
Perfparse compatible output
-t, --timeout=INTEGER
timeout for SNMP in seconds (Default: 5)
-V, --version
prints version number
