[Nagios-users] Nagios v2.9 disappearing hosts/services
Hi all, We're trying to upgrade our nagios monitor from v1.1 to v2.9, however I'm having problems with hosts disappearing from the service details. If I stop nagios and remove the state retention file, then restart nagios all hosts appear again until the status checks start going - at which point hosts disappear again. There is only one nagios process running (as per the FAQ). Without removing the retention file, the host list will still be missing a lot of hosts. Verifying the config using nagios2 -v does not show any errors. Does anyone have any ideas what is going on here?

Re: [Nagios-users] Nagios v2.9 disappearing hosts/services
Replying to myself again... Interestingly enough, it seems that this error seems linked to the number of failures of various services/hosts. I haven't managed to pin out a number as yet, but I can replicate it by adding a dud config file with 20+ services that will always fail (ie become critical). After doing this, I always lose hosts from the Service Detail page. Removing the config file and restarting Nagios makes the problem go away. Enabling it, and the hosts go missing again. Is there any way I can debug this further? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steven Haigh Sent: Monday, 7 May 2007 3:37 PM To: nagios-users@lists.sourceforge.net Subject: Re: [Nagios-users] Nagios v2.9 disappearing hosts/services Hi again all, I am still having an issue with disappearing hosts from the nagios service detail page.

[Nagios-users] Nagios 2.9 and Escalations.
Hi all, I'm currently upgrading our Nagios monitoring system from v1.1 to v2.9 and I notice that the hostgroupescalation functions that we were previously using no longer exist in v2.9. I've read through the docs of serviceescalation and hostescalation and there's one thing that remains unclear to me. If a hostescalation is defined, does this ONLY activate when the host check fails (ie check-host-alive) or if any of the services on the host fails? If it's only triggered on the check-host-alive failing, is there an easy way (ie a wildcard or similar) to activate escalation based on ALL services for a host? Does this require a serviceescalation definition for EVERY service on a host? I sure hope not!

Re: [Nagios-users] Nagios 2.9 and Escalations.
A Thanks Robert. I think it would be of great help if the wildcard
information was on the pages detailing service and host escalations! :)

Re: [Nagios-users] using Nagios to detect rogue DHCP servers?
Indeed. Looking at the source of dhcpdetector.pl
(https://svn.bountysource.com/roguedetect/trunk/dhcpdetector.pl) it shouldn't
be too hard to modify it into a nagios plugin (trivial even).
The relevant code block:
sub send_log {
my $severity = shift @_;
my $message = shift @_;
if (!$message) {
$message = 'ERROR: No Message Recieved, logging failure';
}
# If the above conditions are met and
# the send_msg is set then go ahead and
# log it using the specified log mojo
if ($syslog_level >= $severity) {
syslog('LOG_INFO',$message);
}
if ($email_level >= $severity) {
send_mail($alert_email,"[RogueDetect] Log Report",$message);
}
if ($page_level >= $severity) {
send_mail($page_email,"RogueDetect Failure!",$message);
}
if ($print_level >= $severity) {
print $message . "\n";
}
Should be fairly easy to hook into this, print the correct message and set an
exit code from here

Subject: Re: [Nagios-users] using Nagios to detect rogue DHCP servers?
requires a whole new plugin written from scratch, I haven't seen a
tcpdump like plugin. Therefore much more difficult and more time
required, as well as more computationally intensive to watch all traffic
for another dhcpoffer, when actually you'll get the same result.
What about writing a custom plugin that uses this GPL prog to return the
warning/critical/ok/pending values?
https://roguedetect.bountysource.com/
From the website:
Rogue Detect sends DHCPDISCOVER packets to the network and listens for DHCP
servers to respond and checks responses against authorized dhcp servers. It’s
written in Perl. By default it supports sending reports to syslog, email,
standard out or a customer script of your chosing. Each reporting method has
it’s own independent reporting level.
Their wiki is here: https://roguedetect.bountysource.com/wiki
notes at the bottom of the wiki:
"Sending a DHCPDISCOVER packet causes any DHCPSERVERS listning to allocate an
IP address for a few seconds, while they wait for the detector to ACK their
offer. Since we never do send an ACK, the IP is not allocated to us. Hence, it
should be ok to run this on the network.. but do so at your OWN RISK!!
This package is nice in that you do not have to have a clear view of the
network to run it (ie, it works behind a switch). You DO have to be within
broadcast range, which usually means on the same subnet as the DHCP server. In
some cases scaning port 68 (67?) on every machine may be the better answer to
finding dhcp servers, but with this program, as apposed to a passive one like
snort, you do not have to be able to see traffic not destined for you."
