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 or v2c with option)
-l, --login=LOGIN ; -x, --passwd=PASSWD, -2, --v2c
Login and auth password for snmpv3 authentication
If no priv password exists, implies AuthNoPriv
-2 : use snmp v2c
-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)
-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)
-A, --param
Add parameters to select processes.
ex : "named.*-t /var/named/chroot" will only select named process with this parameter
-F, --perfout
Add performance output
outputs : memory_usage, num_process, cpu_usage
-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
-d, --delta=seconds
make an average of <delta> seconds for CPU (default 300=5min)
-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.
-o, --octetlength=INTEGER
max-size of the SNMP message, usefull in case of Too Long responses.
Be carefull with network filters. Range 484 - 65535, default are
usually 1472,1452,1460 or 1440.
-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
