Re: [Nagios-users] How to get reboot messages
You could also (if it's linux) just put a simple mail command with message in /etc/rc.local which executes after system boot and init. -Don On Thu, 2007-11-29 at 11:59 -0600, chris serafin wrote: > I have a bunch of devices which alert me fine up/down, but I'm looking > to find how to get messages when they reboot.

Re: [Nagios-users] Centralizing NRPE Configuration
This was a learning curve for me but once I got it up and going using Puppet to manage configs enterprise-wide is making things easier: http://reductivelabs.com/trac/puppet Not that this will be what you are looking for, but it will manage configs globally and with invidual nodes defined. It uses cfengine as it's backend. Good stuff, but is a bit of learning curve. -Donnell Lewis On Wed, 2007-11-28 at 09:07 -0500, Cipriani, Robert C wrote: > True, the nrpe config will be generic, and will only have to push nrpe.cfg > when I add new commands.

Re: [Nagios-users] Monitoring Nagios
Hey Jim, I use Monit which will monitor services and makes sure they stay running, there are alot of options and I have it making sure ssh, nagios and HTTP are running on the nagios box. Monit runs via the inittab and if it dies for any reason gets respawned using init and it has notifications it can send out about specific things. You can have it notify just for about anything, maybe this will help you out. http://www.tildeslash.com/monit/ -Donnell Lewis On Wed, 2007-11-28 at 14:52 +0100, Mohr James wrote: > Hi All! > > We had a problem the other day where the nagios process died and no one > noticed it for over 30 minutes.

Re: [Nagios-users] On-Call Rotation
Likewise here, we have a qmail server and I just setup a adminonduty contactgroup and defined a timeperiod for adminonduty contacts and then wrote a simple bash script that looks for the current adminonduty in the adminonduty.cfg file that holds the group definition and according to what the current one is changes that to the next in the list and reloads nagios, then it logs in to the mailserver and sets the adminonduty forwarder to the current email addy of the contact. -Don On Mon, 2007-10-15 at 10:30 -0500, Steve T wrote: > I just created a contactgroup for each of us on call and manually > changed the notification every week.

Re: [Nagios-users] separate webfront
Or you could use the distributed monitoring method: have a master nagios server (running the web front-end) running at one locationa and then have another (or multiple) nagios daemons running on the other boxes that actually check the local machines at that colo and send passive check results via nsca to the master hosting the frontend. -Don On Mon, 2007-09-10 at 17:24 -0400, Cassandra Pugh wrote: > Hugo, perhaps you can elaborate?

[Nagios-users] Hosts/service Acknowledgement comment staleness?
Hey All, I am using version 2.9 currently and am noticing that when I ack a host/service and leave a comment and unchecked the persistent option that when the service or host changes states the acknowledgment comment is not being removed. I know that before I upgraded (was using 2.5) when I left a comment on acknowledging an alert and unchecked the "persistent" option the comment would automatically be removed when the host/service changed states. I'm not referring to the sticky acknowledgment which I know keeps the acks there across program restarts, I'm referring to the 3rd box under send notifications for the persistent option. Anyone else experience this behavior ?

Just out of curiousity have you tried:
# 'check_dns1_random' command definition
define command{
command_namecheck_dns1_random
command_line$USER1$/contrib/check_dns_random.pl "127.0.0.1"
}
and make sure the perms of course are correct on the plugin check.
Don't know if that will help but sometimes I have had to use "" for

You would make your .htaccess or auth schema user the same as the user you put them into contacts.cfg as. Then you would have to create a group just for them in contactgroup.cfg. After that you would then add their contactgroup to the host/services for which they have with you. The ISP cloud will basically show as the central nagios host that's doing the checks, unless you add a host and just name it that for viewing purposes on the map. Then, after you have added them to the auth files, contacts.cfg, contactgroups.cfg and put their group name into the hosts/services they are to see you would also need to make sure that in the hosts/services definitions that you are using the 'parent ' option so that things will fall correctly on the map.

Re: [Nagios-users] nagios startup options
I run it as a user allowed to startup nagios process and have it run as a cronjob. Could also dump as a cron in like /etc/cron.d*, for me I have the nagios user able to startup the nagios process using a sudo ability letting the nagios user just execute that command to startup the process via root. I have our checking on crontab like every 5 or 10 minutes, can't remember which. -Donnell Lewis On Tue, 2006-11-14 at 16:46 -0600, Brian Loe wrote: > On 11/14/06, Donnell Lewis <[EMAIL PROTECTED]> wrote: > > I always like using the nagios process check myself rather than checking > > for the ".pid" file as I have had nagios die off and the ps wasn't > > telling me anything, I use this which works pretty good for me, I also > > use this along with additonal and modified to check our nagios primary > > to make sure it's up and if not startup slave etc. > > > > Where do you run this from?

Re: [Nagios-users] nagios startup options
I always like using the nagios process check myself rather than checking
for the ".pid" file as I have had nagios die off and the ps wasn't
telling me anything, I use this which works pretty good for me, I also
use this along with additonal and modified to check our nagios primary
to make sure it's up and if not startup slave etc.
Might want to give this a try, edit according to your install of
course :
#!/bin/bash
plugindir="/usr/local/nagios/libexec"
cmdstart='/sbin/service nagios start'
#Check nagios with check_nagios plugin
$plugindir/check_nagios -e 5 -F /usr/local/nagios/var/nagios.log
-C /usr/local/nagios/bin/nagios
if [ "${?}" != 0 ] ; then
echo "CRITICAL:Nagios not found running..."
$cmdstart
else
echo "OK:Nagios runnning..."
fi
exit

Re: [Nagios-users] nagios startup options
Well, This would solely depend on what distro you are running it on I would imagine. I run mine on redhat, so when I installed it it put the proper files in the /etc/rc.d directories and /etc/init.d and all I had to do was chkconfig --add nagios. Not sure what distro you are using but you could add it to your init/rc directories the old POSIX way if you aren't using a package manager or service control files, otherwise you could start it up in /etc/rc.local file. As for making sure to restart if it dies, well, that could be done by writing a little bash script that check to see if the nagios process itself is running and if not start it up through the service control or command line string. You really needed to provide a little more info like what distro etc you are running, but that's the gist of it. -Donnell Lewis On Tue, 2006-11-14 at 13:55 -0600, Brian Loe wrote: > What is the best, safest way to have Nagios start at boot?

Re: [Nagios-users] How can you set service check execution time? (aside from passive cron)
Should be able to create another timzperiod config in the timeperiods.cfg I would imagine and in the service definition use the check_period Could have additional timeperiod definition for a certain time each day which would execcute the service checks JUST between those times. Think I am on the right track with that. -Don Lewis On Mon, 2006-11-13 at 10:11 +, Peter Farrell wrote: > How can you set service check execution time?

Re: [Nagios-users] Running check_nagios by ssh
Here is a script I wrote for checking that the master is running or not
and it will ENABLE/DISABLE the service checks and notifications
accordingly on the slave depending on it's check results of the master.
You will need to edit the variables accordingly and remove the rsync
stuff as I used it to automatically turn the rsync cron ON/OFF. I run
this on a cron. The use of sudo in this script is because I am running
it as the nagios user and it needed it for adjusting the rsync cron, but
you can remove the rsync stuff and add your own if you want it to do any
additional functions beyond ENABLING/DISABLING service checks and notifs
on the slave. Please keep in mind this script is rudimentary and could
be streamlined alot, I just haven't gotten around to it..

be able to locate a running
# Nagios process on the primary it will send commands to the nagios.cmd
file on the slave that will
# enable "service checks" and "notifications" and disable the companion
rsync script. Once this

will send commands to

Oh, and a side note, make sure of course that you add the same username to the web auth that you use for the contact in contact.cfg. -Don Lewis On Wed, 2006-10-25 at 14:30 +0100, Wheeler, JF (Jonathan) wrote: > I have a Nagios installation with ~700 hosts and ~11000 services.

Re: [Nagios-users] Viewing a subset of systems checked by Nagios
Yes this is possible. You would need to add the client(person) to the contacts.cfg file and then either to an existing contact group in contactgroups.cfg or make a new contactgroup specifically for that client. Unless given ALL privs in cgi.cfg every each user that has been added to the authentication mechanism will only be allowed to see hosts/services for which they are contacts for. So remember to add the contactgroup you create to the host & the services for that host ( in services.cfg ) and they will then be able to see the host and associated services for it. By adding this new contact and contactgroup you can even specifically send them alerts of their own at intervals they want them at, and when they log in through the web interface they will only be able to see the hosts/services you have given them access to, and when they look at the status map they will only see the hosts/services you have assigned them, the rest will be ? marks on the map, everywhere else they will just see theirs. Hope that helps. -Don Lewis On Wed, 2006-10-25 at 14:30 +0100, Wheeler, JF (Jonathan) wrote: > I have a Nagios installation with ~700 hosts and ~11000 services.

Re: [Nagios-users] Bizarre Behavior: Nagios Runs of Redhat Linux, but not Fedora
Well, as for permissions, if I'm not mistaken in the docs somewhere it states to make sure you have SELinux disabled. So you also may want to make sure that is the case on your box as well. -DL On Fri, 2006-09-15 at 10:50 -0700, Vern Kyle wrote: > I doubt it's a permission issue.
