40 -H, --hostname=HOST\n\
41 Name or IP address of the device you wish to query\n\

43 Object identifier(s) whose value you wish to query\n\
44 -w, --warning=INTEGER_RANGE(s)\n\

48 -C, --community=STRING\n\
49 Optional community string for SNMP communication\n\
50 (default is \"%s\")\n\
51 -u, --units=STRING\n\
52 Units label(s) for output data (e.g., 'sec.').\n\
53 -p, --port=STRING\n\
54 UDP port number target is listening on. Default is \"%s\"\n\
55 -d, --delimiter=STRING\n\
56 Delimiter to use when parsing returned data. Default is \"%s\"\n\
57 Any data on the right hand side of the delimiter is considered\n\
58 to be the data that should be used in the evaluation.\n\
59 -t, --timeout=INTEGER\n\
60 Seconds to wait before plugin times out (see also nagios server timeout).\n\
61 Default is %d seconds\n\

64 -s, --string=STRING\n\
65 Return OK state (for that OID) if STRING is an exact match\n\
66 -r, --ereg=REGEX\n\
67 Return OK state (for that OID) if extended regular expression REGEX matches\n\
68 -R, --eregi=REGEX\n\
69 Return OK state (for that OID) if case-insensitive extended REGEX matches\n\
70 -l, --label=STRING\n\
71 Prefix label for output from plugin (default -s 'SNMP')\n"
73 #define NOTES "\
74 - This plugin uses the 'snmpget' command included with the UCD-SNMP package.\n\
75 If you don't have the package installed, you will need to download it from\n\
76 http://ucd-snmp.ucdavis.edu before you can use this plugin.\n\
77 - Multiple OIDs may be indicated by a comma- or space-delimited list (lists with\n\
78 internal spaces must be quoted)\n\
79 - Ranges are inclusive and are indicated with colons. When specified as\n\
80 'min:max' a STATE_OK will be returned if the result is within the indicated\n\
81 range or is equal to the upper or lower bound. A non-OK state will be\n\
82 returned if the result is outside the specified range.\n\
83 - If spcified in the order 'max:min' a non-OK state will be returned if the\n\
84 result is within the (inclusive) range.\n\
85 - Upper or lower bounds may be omitted to skip checking the respective limit.\n\
86 - Bare integers are interpreted as upper limits.\n\
87 - When checking multiple OIDs, separate ranges by commas like '-w 1:10,1:,:20'\n\
88 - Note that only one string and one regex may be checked at present\n\
89 - All evaluation methods other than PR, STR, and SUBSTR expect that the value\n\
90 returned from the SNMP query is an unsigned integer.\n"
