Re: [Nagios-users] Nagios configuraion best practice
Hi all,
I'm picking up this old tread, as I'm about to start restructuring
parts of my Nagios configuration. In my current configuration I've
created host groups to which I've linked both hosts and services.
Example: I have a host group called linux-servers, to which all
linux servers are linked. A number of service checks common for all
linux servers are also linked to this host group. When adding new
linux boxes I simply link them to the linux-servers host group. In a
similar fashion I have a host-group called application-servers to
which all application servers and related service checks are linked.
When adding a new application server, I make sure it links to both
linux-server and applications-servers.
This setup works pretty well, but it really clutters up the host
groups web page. Is this the way others have structured their nagios
configuration?
Regards,
Kenneth

I should have been more precise regarding the cluttering of the display - it
was the hostgroup display I was referring to. :/
Would it be an idea to as much as possible use this configuration method:
hosts --- hostgroups --- services? To elaborate some: Hosts are always
connected to host groups, and the same for services. This way one will
avoid linking services to specific hosts, making the service definitions
more clean.
Also, I'm thinking about having a host group called for example
linux-servers, to which all linux servers are linked. A number of service
checks common for all linux servers are also linked to this host group. When
adding new linux boxes I simply link them to the linux-servers host group,
and add extra services checks where needed. In a similar fashin I would
create a host-group called for example dell-servers to which all Dell
hosts and related service checks are linked. New Dell servers are then
linked to this host group.
I'm thinking this may be a good idea, but would like to hear how others have
structured their configuration and if there may be some hidden pitfalls in
my proposed configuration method.

Not quite sure what you're trying to do. If you monitor a service,
it's going to be on the nagios
service details pagre regardless, That's the whole point. There are
some tricks to slim down
some other displays eg I define a whole bunch of services under a host
without defining the
hosts these services run on explicitly. I just feed the IP address as
part of the check_command.
This reduced the hostgroup grid page. I don't think that will work for
you.
If you're asking how to most efficiently code this in your configs,
the timesaving tips page
mentions ganging together services. ie you don't need a service stanza
for each host you want
to run this on. Rather, use a wildcard or group.
define service{
use generic
host_namehosta, hostb
hostgroup special-ones,!webguy
.
}
Run the service on hosts hosta, hostb, all hosts in the hostgroup,
special-ones but not webguy
One other thing you should consider. Where will the plugins live? The
easy answer is to put them
on an NFSmounted partition that all hosts can access and that you can
easily update. This is a
bad practise. What happens when NFS breaks? You should really copy the
plugins to each
host st they run locally.

Thanks for the reply. I'll read the documents you listed.
Meanwhile, I have a design question: What's the best way to set up a
service
check to be executed on a selected few (or maybe all for that matter)
nodes?
Say I need to monitor a particular process (lets call this service A) on
a
number of systems, how would I implement this? I guess one way would be
to
link service A to a hostgroup, say hostgroup A, and add the selected
systems
to that hostgroup. This, however, will somewhat clutter up the web
display,
so I'm looking for alternative approaches.
Any suggestions?

[Nagios-users] Network and machine resource consumption for Nagios
Hi. Is there any resource consumption with regards to network or server/client machines to worry about when running Nagios? We're running active checks, i.e. the Nagios server uses SSH to run plugins on the client side and gather the information. I guessing that the per service per check interval load on the network is a matter of a couple of very small packets travelling between the Nagios server and the Nagios client. And on the client side it is only a matter of running small, simple scripts that causes very little processing overhead. Thus, all in all there shouldn't be much of a overhead to talk about when running Nagios? Of course, it all depends on the check interval and the number of checks, and if anyone knows any nagios check per processing/network capacity ratio please speak up.

I does indeed seem like the notifications are sent out just like I was

It should be left at 0 to get the behavior you're expecting. With
notification_interval 0, a notification for a {WARNING | CRITICAL | OK/
RECOVERY} state will only be sent once per problem. That's what you
want. When set at 1440, you'll receive repeat notifications every 24
hours until recovery.
http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#service
notification_interval: This directive is used to define the number
of time units to wait before re-notifying a contact that this
service is still in a non-OK state. Unless you've changed the
interval_length directive from the default value of 60, this number
will mean minutes. If you set this value to 0, Nagios will not re-
notify contacts about problems for this service - only one problem
notification will be sent out.
This is my current definition:
define service {
use generic-service
service_description Current load for virtual
servers
servicegroups performance
hostgroups virtual-servers
is_volatile 0
check_period24x7
max_check_attempts 3
normal_check_interval 5
retry_check_interval1
notification_interval 0
notification_period 24x7
check_command check_remote_load!/home/
nagios/.ssh/id_rsa!nagios!13.0,8.0,3.0!15.0,10.0,5.0
}
This isn't the entire service definition (no contacts specified, no
notification_options, what's in the template?, etc). That's why I
suggested getting that (and more) from objects.cache. You might also
want to include the log entries for the service and notifications to
exemplify the problem.
Setting this attribute to a higher value should make me get a lot
less notifications, but I will still get more or less duplicate
notifications. Help on avoiding this will be appreciated.
You just made it worse by saying you _should_ get repeat notifications
once a day at least. ;)
Regarding your specific questions: I think the service definition
above answers most of them.
Not really, it's missing the key bits of information about who gets
notified for what, when and how.
We don't run multiple Nagios daemons on the same machine.

Re: [Nagios-users] Limiting mail notification for clock drift
I think I found one of the causes for the excessive notifacations - the
notification_interval was set to 0. For almost all our services we have a
high number (such as 1440), but this current value of zero must have made
it's way into the code somehow. This is my current definition:
define service {
use generic-service
service_description Current load for virtual servers

check_command
check_remote_load!/home/nagios/.ssh/id_rsa!nagios!13.0,8.0,3.0!15.0,10.0,5.0
}
Setting this attribute to a higher value should make me get a lot less

That's interesting. That's about the only option that would cause the
behavior you are reporting that I can think of. Are you using event
handlers for notifications? Is your notification_interval the same or
similar to your normal_check_interval? Make sure that you don't have
multiple nagios daemons running at the same time and that the service
definition in objects.cache is as you expect it to be.
The only case in which nagios cares about the _text_ of the plugin
output is when state stalking is enabled. Even then, it only provides
logging of that change, not a notification. There are only two
conditions under which notifications will be sent out (
http://nagios.sourceforge.net/docs/3_0/notifications.html)--
When Do Notifications Occur?
The decision to send out notifications is made in the service check
and host check logic. Host and service notifications occur in the
following instances...
* When a hard state change occurs. More information on state
types and hard state changes can be found here.
* When a host or service remains in a hard non-OK state and the
time specified by the notification_interval option in the host or
service definition has passed since the last notification was sent out
(for that specified host or service).
I think it would be correct to sum up what I'm in need of like this:
Whenever there is a transition from one hard error state to another
hard error state, or when there has been a recovery from such an
error, I'd like a notification.
Yup. Standard Operating Procedure for nagios. You have to do something
unusual to not get this behavior. Perhaps you should post some config
information from objects.cache for inspection. service definition,
contact definition and notification command definition.

[Nagios-users] Limiting mail notification for clock drift
Hello. I'm using Nagios 3.0.3 to monitor things such as time (synchronized with NTP) on our servers, and are getting a lot of semi-duplicate notification mails: As long as there is an error/warning, I get a mail notification every time the clock drift increases or decreases. Is there an option I can set to limit the notification to _one_ mail whenever we enter or leave an error/warning state, and thus not for every time a new drift time is calculated? The same problem also applies to things such as disk space.

Re: [Nagios-users] Monitoring 64-bit and 32-bit servers - plugin path problem
Quite a lot of ways to solve this issue, it seem. :)
I have a working configuration in which the $USER macro is defined with
/usr/lib*64*/nagios/plugins/check_disk, and on 32-bit systems I make a
symlink from /usr/lib64/nagios to /usr/lib/nagios. This works like a charm,
and doesn't seem to be very messy.
I may consider the Gavins approach setting the PATH environment though,
since it looked like a very neat solution.

Kenneth,
Here are two more ideas for you:
1) You could add some test logic into your command def, like so:
$USER1$/check_by_ssh args -C if [ -e /usr/lib64/nagios/plugins/ ] ; then
/usr/lib64/nagios/plugins/check_disk remote args ; else
/usr/lib/nagios/plugins/check_disk remote args ; fi
Rather ugly, but I think that would do what you want.
2) configure the remote ssh client to know it's local path to the plugins;
you
could do this either in the public key, by using something like
'environment=NAGIOSPATH=/usr/lib64/plugins' after your command and host
restrictions (you _are_ using command and host restrictions in your public
keys, right? ;-), or in ~/.ssh/environment on the remote host. Note that
to
use either of those, you'd need to set PermitUserEnvironment=yes in your
sshd_config - see sshd(8) and sshd_config(5). Once that's set, you should
be
able to run:
$USER1$/check_by_ssh args -C \$NAGIOSPATH\/check_disk remote_args
...which would also get you there, I think.
Couple of disclaimers...
- allowing user environments to be set via sshd can be a security risk
- I've only tried this from the command line; you'll likely need to do some
interesting escaping to get it to work correctly.
Also,

Re: [Nagios-users] Nagios configuraion best practice
I should have been more precise regarding the cluttering of the display - it
was the hostgroup display I was referring to. :/
Would it be an idea to as much as possible use this configuration method:
hosts --- hostgroups --- services? To elaborate some: Hosts are always
connected to host groups, and the same for services. This way one will
avoid linking services to specific hosts, making the service definitions
more clean.
Also, I'm thinking about having a host group called for example
linux-servers, to which all linux servers are linked. A number of service
checks common for all linux servers are also linked to this host group. When
adding new linux boxes I simply link them to the linux-servers host group,
and add extra services checks where needed. In a similar fashin I would
create a host-group called for example dell-servers to which all Dell
hosts and related service checks are linked. New Dell servers are then
linked to this host group.
I'm thinking this may be a good idea, but would like to hear how others have
structured their configuration and if there may be some hidden pitfalls in
my proposed configuration method.

part of the check_command.
This reduced the hostgroup grid page. I don't think that will work for you.
If you're asking how to most efficiently code this in your configs,
the timesaving tips page
mentions ganging together services. ie you don't need a service stanza
for each host you want
to run this on. Rather, use a wildcard or group.
define service{
use generic
host_namehosta, hostb
hostgroup special-ones,!webguy
.
}
Run the service on hosts hosta, hostb, all hosts in the hostgroup,
special-ones but not webguy
One other thing you should consider. Where will the plugins live? The
easy answer is to put them
on an NFSmounted partition that all hosts can access and that you can
easily update. This is a
bad practise. What happens when NFS breaks? You should really copy the
plugins to each
host st they run locally.
