77 #define NOTES "\
78 - This plugin uses the 'snmpget' command included with the NET-SNMP package.\n\
79 If you don't have the package installed, you will need to download it from\n\
80 http://net-snmp.sourceforge.net before you can use this plugin.\n\
81 - Multiple OIDs may be indicated by a comma- or space-delimited list (lists with\n\
82 internal spaces must be quoted) [max 8 OIDs]\n\
83 - Ranges are inclusive and are indicated with colons. When specified as\n\
84 'min:max' a STATE_OK will be returned if the result is within the indicated\n\
85 range or is equal to the upper or lower bound. A non-OK state will be\n\
86 returned if the result is outside the specified range.\n\
87 - If specified in the order 'max:min' a non-OK state will be returned if the\n\
88 result is within the (inclusive) range.\n\
89 - Upper or lower bounds may be omitted to skip checking the respective limit.\n\
90 - Bare integers are interpreted as upper limits.\n\
91 - When checking multiple OIDs, separate ranges by commas like '-w 1:10,1:,:20'\n\
92 - Note that only one string and one regex may be checked at present\n\
93 - All evaluation methods other than PR, STR, and SUBSTR expect that the value\n\
94 returned from the SNMP query is an unsigned integer.\n"
