Subject: [Nagios-users] Using SEC with Nagios for SNMP trap processing

I am thrilled with the prospect of using SEC to process SNMP traps, but 
I am wondering the best way to send the received trap(s) to sec.pl.

Should I setup a "traphandle default" in snmptrapd.conf to pipe each 
trap separately to SEC, or use the traphandle to append to a log file 
then have that log file read by SEC. If it is the latter, then how or 
when does SEC get instantiated so it can read the file and how does 
being able to perform time-based correlation come into play with how 
the traps are read by SEC?

I know I am missing a part of the puzzle here. Otherwise I think I 
understand how to integrate SEC into Nagios as far as setting up the 
passive service and using SEC to write to nagios.cmd.

I use some perl to query switches and define ports as services, so that 
as new ports are brought into use they are added to Nagios. I guess one 
could do something similar for system hosts and the services run on 
them. If it would help I can send you an example but you would have to 
wade through perl and modify it to be useful.

Subject: [Nagios-users] check_nt memuse - can I separate RAM from swap

Hi

When I use check_nt to see the memory usage I get the overall value of RAM
and swap. This isn't really helpfull because there is no way that the
system can use entire swap - especially when there's about 500MB
dynamically assigned. Is there a way to configure nagios or the NT 4.0
server to see RAM and swap info separatly?

Subject: [Nagios-users] Respond to pages

I did a quick search of the mailing list archives and didn't find
anything.

Before I start on this, I'd like to see if anyone has done something
similar.

Currently I have pages going to our admins skytel accounts. I'd like
them to reply with an "Ok" or "Thank You" (two default options) which
would go to nagios on the server. Then a procmail script (for example)
would take those replies and, if an "Ok" page was returned, disable
further pages. One additional page would go out to the page group
indicating the admin who said "Ok" would handle the incident.

Perhaps "Thank You" would page out acknowledgement of the page to the
page group members.

Anyway, has any work on such a beast been done? Is someone else perhaps
working on this idea and I can test?

Thanks,

Carl

To answer your question: I don't know.

However, what I did was to figure out the percent usage that would equal
the value I was looking for less the swap space. Here's an example,
because that is worded so poorly.

I have 1 gig of RAM and a 2 gig swap or pagesys. Total that is 3 gig.
However, I want to know when my RAM reaches 75% utilization. So take
the 768 MB, plus your minimum pagesys size (for me 2048 MB) and you get
2816 which is 92%. Maybe I've got some bad logic here, but I'm sure
I'll hear about it if I do.

NSClient is dependent on the available Windows performance
counters. The normal ones are a rather odd bunch, none of
which seem to be able to answer the simple question "how
much physical memory is being used?".

You can ask "how much physical memory is left?" by using

-v COUNTER -l "\\Memory\\Available Mbytes"

in your check_nt command. You can also use "Available
Bytes" and "Available Kbytes".

The explanation of the counter is ... "Available MBytes is the
amount of physical memory available to processes running on the
computer, in Megabytes (Bytes / 1,048,576). It is calculated
by summing space on the Zeroed, Free, and Stand by memory
lists. Free memory is ready for use; Zeroed memory are pages
of memory filled with zeros to prevent later processes from
seeing data used by a previous process. Standby memory is
memory removed from a process' working set (its physical
memory) on route to disk, but is still available to be
recalled. This counter displays the last observed value
only; it is not an average."

Subject: [Nagios-users] How many passive service check results per second ?

Hi,

we have set up Nagios with ditributed monitoring.
The Nagios-Master gets only passive service check results
fron the distributed monitors (about 8000 per hour)
and does not run any eventhandler.

We see a lot of failed send-nsca commands on the disributed monitors
and the external command file at the master is most of the time
nearly 4k big (is this the maximum for a FIFO-stack ?)

Setting the command check interval to 2s results in an increasing
number of nagios processes, but the external command file becomes
only 1.5k big and most send-nsca are successful.

What is the maximum number of passive service check results nagios
can handle ? It is running on a dual PII 1,26Ghz with 1GB RAM.

Thanks
Bernhard

Subject: [Nagios-users] Notification Specifics on V1.1

Afternoon,

Running Nagios on an OS X.2.8 server. Runs fine,
however all the talk about send mail and the
alternatives has me curious how Nagios actually
forwards notifications. I'm assuming Nagios utilizes
the misccommands.cfg but I would like to know if can
simply call to any email program for notifications.

For example, this install of nagios is deployed in a
university enviroment and establishing sendmail or
alternative would be completly redundant with the
university supporting mail services. Or my
inexperience with sendmail has me confused.

I can't imagine that I'm the only one with the
privilege and perhaps the pitfall of a managed mail
service. With that said, I simply want nagios to
forward notifications to a unix based email program
(mta) which will email the notifications via the
university smtp server.

I believe i have provided enough information so I look
forward to the responses.

Regards

axiom

Subject: [Nagios-users] Whoops!

yo instale nagios y ya esta corriendo, cuando verifico antes de iniciar
me dice que no hay problemas ninguno, 0 errores y 0 warnings, cuando lo
arranco me dice 

No lock file found in /usr/local/nagios/var/nagios.lock

al parecer arranca sin problemas 


en la interface web, la parte de la ayuda funciona sin problemas, pero
la parte de los cgi, no funciona bien, me sale el cartel que dice
Whoops! 

The most common cause of this error message (especially for new users),
is the fact that Nagios is not actually running. If Nagios is indeed not
running, this is a normal error message. It simply indicates that the
CGIs could not obtain the current status of hosts and services that are
being monitored. If you've just installed things, make sure you read the
documentation on starting Nagios. 

Some other things you should check in order to resolve this error
include: 

Check the Nagios log file for messages relating to startup or status
data errors. 
Always verify configuration options using the -v command-line option
before starting or restarting Nagios! 
Make sure you've compiled the main program and the CGIs to use the same
status data storage options (i.e. text file or database). If the main
program is storing status data in a text file and the CGIs are trying to
read status data from a database, you'll have problems. 

Make sure you read the documentation on installing, configuring and
running Nagios thoroughly before continuing. If all else fails, try
sending a message to one of the mailing lists. More information can be
found at http://www.nagios.org.

Hm. Maybe this is why my parents aren't working as I'd hoped.

Are you saying that if I have:

nagios host -> router1 -> router2 -> router3 -> monitored host

...and router1 is a parent of router2, and router2 is a parent of
router3, and router3 is a parent of monitored host, then all four have
to be down before nagios will mark monitored host as unreachable?

If that's the case, then I'm getting rid of router1 and router2 from my
setup.

Or do you mean:

router1 -
\
- monitored host
/
router2 -

?

You're asking two different questions. The arguments for each check
command are specific to that command. For example, running check_http
--help shows all the possible command arguments for check_http which are
very different than for check_ntp (check_ntp --help). You may or may not
need/want to use $ARGx$ macro substitution for one or more of the
command options entirely at your discretion.

$ARGx$ macros are not complicated. The only documentation that should be
necessary is=20

http://nagios.sourceforge.net/docs/1_0/configmain.html#resource_file

and the examples in resource.cfg.
http://nagios.sourceforge.net/docs/1_0/macros.html shows where you can
use each of the pre-defined macros and the user specified $ARGx$ macros
(at the bottom).

Nagios doesn't speak SMTP so it needs to pass the email off to some
program on your linux box that can do mail delivery. Typically this is
/bin/mail which then processes it with whatever SMTP daemon it is
configured to use (typically sendmail). You have two primary options:

1) configure sendmail or other MTA on your linux box to smarthost to
your managed mail servers or
2) http://www.nagios.org/faqs/viewfaq.php?faq_id=3D150=20

This.

The logic is that if router1 is down, monitored host should still be reachable
via router2, and so both routers must be down for Nagios to consider monitored
host to be unreachable.

I believe that someone did some type of calculation for this last year.
For what it's worth, I have 2559 services at 5 minute intervals (all
passive using 4 data collectors reporting all checks to 2 centralized
host for duplication) which equates to about 31,000 per hour and nagios
doesn't even break a sweat. It's currently running on a quad P3 500mhz
with a gig of ram but nagios rarely uses significant resources on the
box and I've had it running on lesser boxen.

Passive Checks: Time Frame Checks Completed=20
<=3D 1 minute: 219 (8.6%)=20
<=3D 5 minutes: 2545 (99.5%)=20
<=3D 15 minutes: 2559 (100.0%)=20
<=3D 1 hour: 2559 (100.0%)=20
Since program start: 2559 (100.0%)=20
=20

You don't say how often you are checking your services and that will
have a _big_ impact on nagios performance. If I were doing the same
checks above at 1 minute intervals I'd probably be killing nagios. Some
of my pertinent nagios.cfg settings are below --

service_reaper_frequency=3D5
retention_update_interval=3D5
aggregate_status_updates=3D1
command_check_interval=3D-1

Subject: [Nagios-users] Byzantine configs? Or am I doing it wrong?


We have eight backup servers in several different locations. We've got
multiple people responsible for their care and feeding. We want to check
pings to all of these servers and ssh access to some of them. Some of the
servers are more critical than others and -one- guy gets paged if these
aren't pingable.

So, I add all this to Nagios... 

* A contact for each back admin including a separate pager contact for the
guy who gets pages.
* A contact group that includes the backup admins.
* A separate contact group that only includes the pager contact.
* Host entries for each of the 8 servers.
* A hostgroup so that the backup-admins can see their servers grouped nicely
together in the web interface.
* A ping service containing the hosts that we don't want to send pages for.
* A ping service containing the hosts that we do want to send page for.
* An ssh service containing the hosts that we need to check ssh on.

Am I making it harder than it needs to be?

utils.pm is normally fixed by the configure/make process.

change the "use lib utils.pm;" line to point to the directory containging 
utils.pm - usually "use lib /usr/local/nagios/libexec;"

Hi!

I need to query nagios about the status of services, but an host
different from the nagios host.

Is there a command with this function??

Es.:

# check_service_status 

# check_service_status mynagios.foo.it dns.foo.it DNS
STATUS OK (exit 0)

Thanks, Massimo.

Massimo,

There's no such thing that I've found. The solution I've taken is having =
an event handler create a zero-byte file on the machine that's =
concerned.

For example:
- Monitor machine A's disk space because machine B needs to put stuff =
there
- Write an event handler so that if A.disk goes critical, write a 0 byte =
file on machine B=20
(like /var/tmp/a_disk_full) saying so. When the service goes back to =
normal, rm the file.
- Update whatever program needs to know, to look for that file.

I think it'll work just fine.

Does this mean that in 2.x you will be able to have sub-groups (groups
