From 024d268386353133af1a9ff5c0b5879397c19b1c Mon Sep 17 00:00:00 2001 From: Sven Nierlein Date: Wed, 17 Nov 2021 11:58:41 +0100 Subject: check_snmp: fix performance thresholds when using multiple oids when using check_snmp with multiple oids it simply printed the unparsed content from -w/-c into the thresholds for each oid. So each oid contained the hole -w from all oids. ./check_snmp ... -o iso.3.6.1.2.1.25.1.3.0,iso.3.6.1.2.1.25.1.5.0 -w '1,2' -c '3,4' before: SNMP ... | HOST-RESOURCES-MIB::hrSystemInitialLoadDevice.0=393216;1,2;3,4 HOST-RESOURCES-MIB::hrSystemNumUsers.0=24;1,2;3,4 after: SNMP ... | HOST-RESOURCES-MIB::hrSystemInitialLoadDevice.0=393216;1;3 HOST-RESOURCES-MIB::hrSystemNumUsers.0=24;2;4 This also applies to fixed thresholds since check_snmp translates negative infinities from: '~:-1' to '@-1:~' --- plugins/check_snmp.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) (limited to 'plugins/check_snmp.c') diff --git a/plugins/check_snmp.c b/plugins/check_snmp.c index afc568b2..58d46b11 100644 --- a/plugins/check_snmp.c +++ b/plugins/check_snmp.c @@ -468,6 +468,9 @@ main (int argc, char **argv) /* Process this block for numeric comparisons */ /* Make some special values,like Timeticks numeric only if a threshold is defined */ if (thlds[i]->warning || thlds[i]->critical || calculate_rate) { + if (verbose > 2) { + print_thresholds(" thresholds", thlds[i]); + } ptr = strpbrk (show, "-0123456789"); if (ptr == NULL) die (STATE_UNKNOWN,_("No valid data returned (%s)\n"), show); @@ -581,14 +584,16 @@ main (int argc, char **argv) if (warning_thresholds) { strncat(perfstr, ";", sizeof(perfstr)-strlen(perfstr)-1); - strncat(perfstr, warning_thresholds, sizeof(perfstr)-strlen(perfstr)-1); + if(thlds[i]->warning && thlds[i]->warning->text) + strncat(perfstr, thlds[i]->warning->text, sizeof(perfstr)-strlen(perfstr)-1); } if (critical_thresholds) { if (!warning_thresholds) strncat(perfstr, ";", sizeof(perfstr)-strlen(perfstr)-1); strncat(perfstr, ";", sizeof(perfstr)-strlen(perfstr)-1); - strncat(perfstr, critical_thresholds, sizeof(perfstr)-strlen(perfstr)-1); + if(thlds[i]->critical && thlds[i]->critical->text) + strncat(perfstr, thlds[i]->critical->text, sizeof(perfstr)-strlen(perfstr)-1); } strncat(perfstr, " ", sizeof(perfstr)-strlen(perfstr)-1); -- cgit v1.2.3-74-g34f1
