-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 or v2c with option)
|
||
|
-2, --v2c
|
||
|
Use snmp v2c
|
||
|
-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
|
||
|
-1 for no warning, MAX must be >0. Ex : -w-1,50
|
||
|
-c, --critical=MIN[,MAX]
|
||
|
number of process that will cause an error (
|
||
|
-1 for no critical, MAX must be >0. Ex : -c-1,50
|
||
|
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
|
||
|
-g, --getall
|
||
|
In some cases, it is necessary to get all data at once because
|
||
|
process die very frequently.
|
||
|
This option eats bandwidth an cpu (for remote host) at breakfast.
|
||
|
-t, --timeout=INTEGER
|
||
|
timeout for SNMP in seconds (Default: 5)
|
||
|
-V, --version
|
||
|
prints version number
|
||
|
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
