print <<EOT;
-v, --verbose
print extra debugging information (and lists all storages)
-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 SNMP v1)
-l, --login=LOGIN
Login for snmpv3 authentication (implies v3 protocol with MD5)
-x, --passwd=PASSWD
Password for snmpv3 authentication
-p, --port=PORT
SNMP port (Default 161)
-n, --name=NAME
Name of the process (regexp)
No trailing slash !
-r, --noregexp
Do not use regexp to match NAME in description OID
-f, --fullpath
Use full path name instead of process name
(Windows doesn't provide full path name)
-w, --warn=MIN[,MAX]
Number of process that will cause a warning
-c, --critical=MIN[,MAX]
number of process that will cause an error
Notes on warning and critical :
with the following options : -w m1,x1 -c m2,x2
you must have : m2 <= m1 < x1 <= x2
you can omit x1 or x2 or both
-m, --memory=WARN,CRIT
checks memory usage (default max of all process)
values are warning and critical values in Mb
-a, --average
makes an average of memory used by process instead of max
-u, --cpu=WARN,CRIT
checks cpu usage of all process
values are warning and critical values in % of CPU usage
if more than one CPU, value can be > 100% : 100%=1 CPU
-t, --timeout=INTEGER
timeout for SNMP in seconds (Default: 5)
-V, --version
prints version number
-g (--rrdgraph) Create a rrd base if necessary and add datas into this one
--rrd_step Specifies the base interval in seconds with which data will be fed into the RRD (300 by default)
-S (--ServiceId) Oreon Service Id
Note :
CPU usage is in % of one cpu, so maximum can be 100% * number of CPU
example :
Browse process list : <script> -C <community> -H <host> -n <anything> -v
the -n option allows regexp in perl format :
All process of /opt/soft/bin : -n /opt/soft/bin/ -f
All 'named' process : -n named
