Re: [Nagios-users] Any numbers on sizing a nagios server?
We're using a similar hardware config to the one Jake mentioned below and nagios 2.10. We push nagios slave servers to anywhere between 6000 and 7000 services per slave (though service latency starts to climb quickly around 7000.) Most services are checked every 5 minutes. The master server handles all host checks. We've been able to scale this config up to about 7800 hosts and 5 services in a single datacenter. This includes 1 nagios master and 8 nagios slaves. Your mileage will vary and as Jake mentioned, your environment may have a large impact on expected performance. -Aaron Devey Paulus, Jake wrote: > Nagios performance is very much specific to your environment.

Re: [Nagios-users] Hosts reboots too fast for check_alive notification
You could have the server fire a script during reboots that submits a check result to nagios via NSCA. It might be a little more elaborate than what you were looking for, but it will always catch a reboot even when a host check misses it. -Aaron Rodrick Brown wrote: > When one of my hosts reboots I’m never notified about the outage. > Currently I’m using a custom script S99bootnotify to alert me when a > host comes online, is there any way to shorten the polling for > check_alive?

Re: [Nagios-users] Host checks under Nagios 1.x
I had a similar problem to this. I only wanted to know if a not-so-important device had been down for an hour or more. Here's what I ended up doing: I disabled the host check (by having it call an "always-ok" checkcommand that always returns 0.) I then added a 'PING' service to the host with a max_check_attempts of 7, and a retry_check_interval of 10 minutes. The pitfall being that I no longer receive 'HOST DOWN' alerts for that host. I instead receive alerts for a failing 'PING' service. -Aaron Andrew Cruse wrote: > I've got an interesting problem with a particular setup.

Re: [Nagios-users] Notifications
What are your notification options set to? In 2.9 the default is "none" so if you didn't specify them for that service, it won't alert. If that's not the answer, perhaps you can paste your the definitions for your service, contact, and notification command? -Aaron Jerad Riggin wrote: > > I have a nagios 2.9 install.

Re: [Nagios-users] how to use servicedependency?
If I am reading your question right, the dependency works, but currently
you get alerts for sv1.dummy1 AND sj2.router1, and you only want alerts
for sj2.router1. If this is the case, you could try setting up
sv1.dummy1 so that it doesn't alert. Unfortunately, you might run into
problems with getting sj2.router1 to recognize a recovery if sv1.dummy1
recovers first. You could try a circular dependency (and I'm not even
sure if you can do that in nagios) where sj2.router1 only runs if
sv1.dummy1 is failing, and sv1.dummy1 only runs if sj2.router1 is
passing. But then you might get a problem where neither check runs
because sv1.dummy1 is passing, and sj2.router1 is failing.
This is a difficult problem to solve with service dependencies.
Basically you want to go critical if both AND fail. But recover if either OR pass.
Unfortunately, the way your service dependency works, the status of
is directly tied to the status of . And
never updates if passes. So you really need to
determine the status of both checks and alert accordingly, or you need
an event handler for to submit an 'OK' status for
when it's passing.
The first of those two options is definitely the easiest. It simply
consists of a small shell script that runs and if
fails, returns the status of . Consider a script such as the
following:
#!/bin/bash
CHECK_ONE="/path-to-checks/check_ping -H $1 -t 2 -p 2 -w 500,50% -c 999,99%"
CHECK_TWO="/path-to-checks/check_ping -H $2 -t 2 -p 2 -w 500,50% -c 999,99%"
if $CHECK_ONE >/dev/null 2>&1; then
echo "Check one OK."
exit 0
else
exec $CHECK_TWO
fi
Replacing your own check commands in CHECK_ONE and CHECK_TWO of course.
The first one would be the equivalent of your "check-link" command. The
second would be the equivalent of your "check_nrpe!check_router1"
command. Note that in this case I used $1 and $2, so the first argument
to the script would be the first host to check, the second argument
would be a second hostname. You don't have to use arguments and could
just hard-code the values into your script, but it makes the script more
scalable if your installation grows. The second check is ONLY executed
if the first one fails.
This way you only need one host, one service, and no dependencies. If
you named your checkcommand "check_double" the service would be
something like:
define service {
use service-template
host_name sj2
service_description sj2.router1
check_command check_double!first_hostname!second_hostname
}
Good luck!

Re: [Nagios-users] Notification on Stalk
The event handler might work but doesn't it stop executing after the service enters a hard state? 0 (At least, that's how I understood nagios 2.x to work, perhaps nagios 3.x differs in this regard.) A clever workaround to this might be to use the performance processing options built into nagios. Perhaps by using the 'service_perfdata_command' and 'process_performance_data' nagios options, and the 'process_perf_data' service directive, you could call a script to process the data, log to a database, send emails, etc. This is not 100% ideal, since nagios should be handling the notifications/emails. Instead of sending the emails, the above said script could also submit a 'critical' passive check to a single volatile service if the status is critical AND has changed... but at this point I think I'm making this more complicated than it needs to be. -Aaron Patrick Morris wrote: > Why not use an eventhandler that parses the plugin output? > > > - > This SF.net email is sponsored by DB2 Express > Download DB2 Express C - the FREE version of DB2 express and take > control of your XML.

Re: [Nagios-users] Notification on Stalk
For what it's worth, I have been looking for a solution similar to this as well. What I'd really like to see is an "event_stalking_options" parameter in nagios where the event handler is called based on the stalking options. In your case, the easiest (but probably most annoying) solution might be to set the notification interval to the same value as your check interval. If your check is running every 5 minutes, and your notification interval is set to fire off every 5 minutes, then each notification sent out will have the latest check results. -Aaron Petersen, Mark wrote: > I've searched high and low for the answer to this.

Re: [Nagios-users] Using nagios for reporting on non-machine data such as employees?
Kelly, I admire your determination to use nagios in many versatile ways. Unfortunately, nagios is probably not the best fit in this case. This is especially true if you really intend to use passive checks instead of leveraging nagios' powerful scheduling or notification features. Plus, adding a new employee could be a potential nightmare if many systems are involved. The effort spent in getting nagios services set up and reto-fitted the way you need would be much better spent on a more conventional solution. Your situation is fairly unique, so I am unable to think of any ready-to-go solutions. In the long run it's probably easiest to periodically upload all this data to a database and put some php scripts together so you can view reports on that data over a web interface. -Aaron Devey Kelly Jones wrote: >We have various systems that keep track of employee data: when an >employee was last paid, hours of sick/vacation leave accrued, >employee's laptop's last IP address (from DHCP server), last time >employee's laptop was backed up (from backup server), whether employee >is on-lave/traveling, whether the employee has been receiving email >(vs employee's mailbox being full, account not setup properly, etc), >etc. > >I realized we could use nagios' "passive service checks" to have the >various systems upload employee data to our nagios server, but was >wondering if this was fitting a round peg into a square hole. > >Is nagios a good tool for monitoring things that aren't machines?
