print_usage();
print <<EOT;
By default, plugin will monitor %used on drives :
warn if %used > warn and critical if %used > crit
-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)
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)
-x, --passwd=PASSWD
Password for snmpv3 authentication
-p, --port=PORT
SNMP port (Default 161)
-m, --name=NAME
Name in description OID (can be mounpoints '/home' or 'Swap Space'...)
This is treated as a regexp : -m /var will match /var , /var/log, /opt/var ...
Test it before, because there are known bugs (ex : trailling /)
No trailing slash for mountpoints !
-q, --storagetype=[Other|Ram|VirtualMemory|FixedDisk|RemovableDisk|FloppyDisk
CompactDisk|RamDisk|FlashMemory|NetworkDisk]
Also check the storage type in addition of the name
It is possible to use regular expressions ( "FixedDisk|FloppyDisk" )
-r, --noregexp
Do not use regexp to match NAME in description OID
-s, --sum
Add all storages that match NAME (used space and total space)
THEN make the tests.
-i, --index
Parse index table instead of description table to select storage
-e, --exclude
Select all storages except the one(s) selected by -m
No action on storage type selection
-T, --type=TYPE
pl : calculate percent left
pu : calculate percent used (Default)
bl : calculate MegaBytes left
bu : calculate MegaBytes used
-w, --warn=INTEGER
percent / MB of disk used to generate WARNING state
you can add the % sign
-c, --critical=INTEGER
percent / MB of disk used to generate CRITICAL state
you can add the % sign
-f, --perfparse
Perfparse compatible output
-S, --short=<type>[,<where>,<cut>]
<type>: Make the output shorter :
0 : only print the global result except the disk in warning or critical
ex: "< 80% : OK"
1 : Don't print all info for every disk
ex : "/ : 66 %used (< 80) : OK"
<where>: (optional) if = 1, put the OK/WARN/CRIT at the beginning
<cut>: take the <n> first caracters or <n> last if n<0
-t, --timeout=INTEGER
timeout for SNMP in seconds (Default: 5)
-V, --version
prints version number
Note :
with T=pu or T=bu : OK < warn < crit
with T=pl ot T=bl : crit < warn < OK
If multiple storage are selected, the worse condition will be returned
i.e if one disk is critical, the return is critical
example :
Browse storage list : <script> -C <community> -H <host> -m <anything> -w 1 -c 2 -v
the -m option allows regexp in perl format :
Test drive C,F,G,H,I on Windows : -m ^[CFGHI]:
Test all mounts containing /var : -m /var
Test all mounts under /var : -m ^/var
Test only /var : -m /var -r
Test all swap spaces : -m ^Swap
Test all but swap spaces : -m ^Swap -e
