Nagios Support Forum

Back in March, I reported in these pages a bug in the way that passive service check data is written to the nagios.log file: Nagios logs bad service-check data https://support.nagios.com/forum/viewtopic.php?f=7&t=61914 For reasons I do not understand, that posting is now locked, and it appears t...

Nagios 4.4.5 is logging inappropriate data in the PASSIVE SERVICE CHECK lines. Specifically, it is logging state and plugin-output data as they existed BEFORE the passive service check is processed, instead of representing data which is the actual incoming service-check result. That is highly confus...

The Nagios Plugins 2.3.0 release added this stanza to the configure.ac file, which is still present at this location in the file in the Nagios Plugins 2.3.3 release: 789 dnl jails on FreeBSD: 790 elif ps -axwo 'stat comm vsz rss user uid pid ppid jid args' 2>/dev/null | \ 791 egrep -i "^ *STAT ...

In nagios-4.4.5/base/broker.c: 535 /* sends contact status updates to broker */ 536 void broker_contact_status(int type, int flags, int attr, contact *cntct, struct timeval *timestamp) { 537 nebstruct_service_status_data ds; Line 537 should be this instead: 537 nebstruct_contact_status_data ds;

In Nagios 4.4.4 base/commands.c , we have the following code fragments: 2358 int process_passive_service_check(time_t check_time, char *host_name, char *svc_description, int return_code, char *output) { 2359 check_result cr; 2360 host *temp_host = NULL; 2361 service *temp_service = NULL; 2362 struct...

I'm not a Github guy (no account there, don't need or want one). No doubt you can copy the info here into such a posting there. This particular issue has not caused a problem in my own usage of Nagios Core; I found it in the source code while looking for something else. But one can easily impute fro...

I'm looking at nagios-4.4.2/base/nebmods.c, lines 421-422 and the surrounding code. The neb_register_callback() routine looks suspect to me in its processing of priority information as it adds event brokers to the callback lists. Specifically, if there is already an existing event broker in the call...

I'm looking at Nagios 4.4.2 code. main() calls daemon_init() [base/nagios.c, line 614] which in turn calls broker_program_state() [base/utils.c, line 2026] to make a NEBTYPE_PROCESS_DAEMONIZE callback. But all of that now happens before neb_init_callback_list() ever gets called [base/nagios.c, line ...

The top-level Nagios-distribution Makefile has a bug: make contrib believes that the contrib directory satisfies the make target by merely existing, as opposed to causing a descent into the contrib directory and building there. The make target should probably be renamed to contribs , and named as su...
