From a1f328900049852d9a2b4c810c28b49e2101e337 Mon Sep 17 00:00:00 2001 From: Ken D Date: Mon, 19 Jun 2017 14:06:05 -0500 Subject: Added option for null zero length string exit codes When using a large distributed network with the same group of checks used against a large number of devices, occationally there are missing cards in a few devices that are present in other devices. Rather than having a large number of unknown results, disable active checking on those large number of result or having to create a unique check configuration for those devices. This option allows you to select an OK, WARNING, CRITICAL or UNKNOWN status while still retaining the default behavior when not present. This also allows a for the check to immediately start checks as intended should the hardware be added that the check is looking for. --- plugins/check_snmp.c | 30 +++++++++++++++++++++++++++--- 1 file changed, 27 insertions(+), 3 deletions(-) diff --git a/plugins/check_snmp.c b/plugins/check_snmp.c index abe54cfb..66d761c6 100644 --- a/plugins/check_snmp.c +++ b/plugins/check_snmp.c @@ -113,6 +113,7 @@ char *authproto = NULL; char *privproto = NULL; char *authpasswd = NULL; char *privpasswd = NULL; +int nulloid = 3; char **oids = NULL; size_t oids_size = 0; char *label; @@ -472,8 +473,16 @@ main (int argc, char **argv) print_thresholds(" thresholds", thlds[i]); } ptr = strpbrk (show, "-0123456789"); - if (ptr == NULL) - die (STATE_UNKNOWN,_("No valid data returned (%s)\n"), show); + if (ptr == NULL){ + if (nulloid == 3) + die (STATE_UNKNOWN,_("No valid data returned (%s)\n"), show); + else if (nulloid == 0) + die (STATE_OK,_("No valid data returned (%s)\n"), show); + else if (nulloid == 1) + die (STATE_WARNING,_("No valid data returned (%s)\n"), show); + else if (nulloid == 2) + die (STATE_CRITICAL,_("No valid data returned (%s)\n"), show); + } while (i >= response_size) { response_size += OID_COUNT_STEP; response_value = realloc(response_value, response_size * sizeof(*response_value)); @@ -661,6 +670,7 @@ process_arguments (int argc, char **argv) {"oid", required_argument, 0, 'o'}, {"object", required_argument, 0, 'o'}, {"delimiter", required_argument, 0, 'd'}, + {"nulloid", required_argument, 0, 'z'}, {"output-delimiter", required_argument, 0, 'D'}, {"string", required_argument, 0, 's'}, {"timeout", required_argument, 0, 't'}, @@ -705,7 +715,7 @@ process_arguments (int argc, char **argv) } while (1) { - c = getopt_long (argc, argv, "nhvVO46t:c:w:H:C:o:e:E:d:D:s:t:R:r:l:u:p:m:P:N:L:U:a:x:A:X:", + c = getopt_long (argc, argv, "nhvVO46t:c:w:H:C:o:e:E:d:D:s:t:R:r:l:u:p:m:P:N:L:U:a:x:A:X:z:", longopts, &option); if (c == -1 || c == EOF) @@ -816,6 +826,12 @@ process_arguments (int argc, char **argv) eval_method[j+1] |= CRIT_PRESENT; } break; + case 'z': /* Null OID Return Check */ + if (!is_integer (optarg)) + usage2 (_("Exit status must be a positive integer"), optarg); + else + nulloid = atoi(optarg); + break; case 's': /* string or substring */ strncpy (string_value, optarg, sizeof (string_value) - 1); string_value[sizeof (string_value) - 1] = 0; @@ -1181,6 +1197,14 @@ print_help (void) printf (" %s \"%s\"\n", _("Delimiter to use when parsing returned data.
