I've got about 200 hosts and about 600 services, with a moderately complex parent/child setup. I'm not doing anything blatantly silly, so is it possible that I've simply done something wrong with my parents definitions, and instead of Nagios telling me so, it just hangs? Lemme know if an strace (or insert favourite debug approach here) will help.

I then use RTG's graphing tools to draw my bandwidth graphs (which is very fast). No MRTG/APAN/CRICKET needed. Also linked the graphs onto my nagios pages using the extended info config files. Part of the info I pull out of the router is the bandwidth statement (which I assume my network guys keep up to date when they change an interfaces BW). Nagios then uses a custom check to compare the current traffic with it's bandwidth and logs if it reaches my specified thresholds. Easy. ;) fred > -----Original Message----- > From: Anders Holm [<A HREF="mailto:anders.holm@elivefree.net">mailto:anders.holm@elivefree.net</A>] > Sent: 22 August 2003 12:30 PM > To: nagios-users@lists.sourceforge.net > Subject: [Nagios-users] Network Badnwidth utilization question > > > Hi Folks. > > I'm wondering, being new to Nagios and all, is there a way to > check a network > device to see if it is reaching it's maximum network > bandwidth?

If you believe this is an error, check the HTTP server authentication=20 requirements for accessing this CGI and check the authorization options in your CGI configuration file." Just for fun, I tried it as guest. No such problem. I tried it as nagiosadmin. No such problem. outages.cgi has mode 755. The parent directory has mode 775. Here are the relevant snippets from my cgi.cfg: use_authentication=3D1 authorized_for_system_information=3D* authorized_for_configuration_information=3D* authorized_for_system_commands=3Dnagiosadmin,jcarro10 authorized_for_all_services=3Dnagiosadmin,guest authorized_for_all_hosts=3Dnagiosadmin,guest authorized_for_all_service_commands=3D* authorized_for_all_host_commands=3D* (NB: I'm logged in as jcarro10.)

Summary: - host check of router fails - single failure notification is sent out - status is never acknowledged - subsequent notifications are never sent - host recovers - recovery notification sent out - host fails again - single failure notification - status is never acknowledged - subsequent notifications are never sent I'm sure you can see a pattern to this. The definition for this host belongs to a hostgroup. That=20 hostgroup belongs to an escalation where first_notification=20 is set to 1 and last_notification is set to 0.
