Re: [Nagios-users] NAGIOS NRPE issue
Finally I managed to run the script with NRPE using root privilegies. The script didn't work. I tried with one of the NRPE samples adding sudo to the command definition: command[check_users]=sudo /usr/lib/nagios/plugins/check_users -w 5 -c 10 I commented the command_prefix option and I commented require_tty in the sudoers file #Defaultsrequiretty I think this last option is needed If you're passing parameters to the script.

Re: [Nagios-users] HTTP server authentication requirements for accessing this CGI.
Hi Shahid & Ankush, Thanks for your replies. But, I guess, these directives are not meant for Nagios on Ubuntu (if one follows the Quickstart Guide). For Ubuntu, the path is "/usr/local/nagios/share". Moreover, I do not have a 'nagios' directory under "/usr/lib/". *New observation*: If the cgi.cfg file is edited to enable 'default_user=nagiosadmin', then I can access the Process Info screen, etc. However, I if try stopping or restarting the nagios service from within the Process Info screen, it errors out stating this: =-=-=-= Error: Could not open command file '/usr/local/nagios/var/rw/nagios.cmd' for update! The permissions on the external command file and/or directory may be incorrect. Read the FAQs on how to setup proper permissions. An error occured while attempting to commit your command for processing. *Return from whence you came* =-=-=-= So, I think it has to do something with authentication.

Thanks for the explanation Michael - this should be very helpful.
Ahh...
Sorry, when you mentioned C++ I assumed you were writing extensions.
External scripts can be used "as normal programs" without any specific
NSClient++ code at all.
Then just follow the regular "writing extensions" guideline for nagios
and you should be fine.
The difference between external script and extensions are that
extensions are running "inside" NSClient and thus can do "more" things
but all in all it is not that much difference so there is no real
benefit (apart from maybe the forking and such).
// Michael Medin
I'm curious though, what are the guidelines around writing a C++
program to be executed as an external script? I've written a simple
program for checking if the driver name supplied as an arg is loaded
in the system, but I'm not using any of the above "glue" to do so, I
just make the checks and printf the output and return the result code.
Is this sufficient? Here's the code;
#include
#include
#include
#include
#include
#define ARRAY_SIZE 1024
int main(int argc, char* argv[])
{
LPVOID drivers[ARRAY_SIZE];
DWORD cbNeeded;
int cDrivers, i;
if(EnumDeviceDrivers(drivers, sizeof(drivers), &cbNeeded) && cbNeeded
< sizeof(drivers))
{
TCHAR szDriver[ARRAY_SIZE];
cDrivers = cbNeeded / sizeof(drivers[0]);;
for (i=0; i < cDrivers; i++ )
{
if(GetDeviceDriverBaseName(drivers[i], szDriver,
sizeof(szDriver) /
sizeof(szDriver[0])))
{
if(argv[1] != NULL && _tcscmp ( szDriver,
_T(argv[1])) == 0)
{
printf("Driver is loaded");
return 0; // OK
}
}
}
printf("Driver is not loaded!");
return 2; // CRITICAL
}
else
{
printf("EnumDeviceDrivers failed; array size needed is %d\n",
cbNeeded / sizeof(LPVOID));
return 3; // UNKNOWN
}
}
It's based off the code here;
http://msdn.microsoft.com/en-us/library/ms682619(VS.85).aspx
I just drop the compiled program into "ExternalScripts" and add this to nsc.ini;
[External Scripts]
check_driver = ExternalScripts\Check_Driver.exe
Is this an appropriate way to carry-out this check? It works perfectly
fine so far, but I'm just curious to see if this is a proper way of
doing things?
Cheers,
Chris

[Nagios-users] hint on service dependency configuration
Hi list,
I need a little input on a configuration problem. I've got a list of
hosts, which are running NRPE to check local services. So, if the nrpe
daemon on one of these hosts stops working, I get alarms for every
configured nrpe-check. Now I thought that the service dependency would
be the configuration of my choice to suppress multiple alarms. But I'm
a bit confused how to configure this correctly.
I'm checking the nrpe service itself on these hosts, and want to
suppress alarms for the other nrpe-based services if the nrpe check
fails. Is there a way to configure this in an optimized way, without
having one servicedependency block for each host and each nrpe check ?
As far as I understand servicedependency config, there can be multiple
hosts as dependent, but only one dependent service with one depending
host and service, which would be a pain to configure with 130 hosts :)
I would imagine doing something like that (for example):
# Suppress notifications for nrpe-based services if nrpe check itself fails
define servicedependency {
host_name *
service_description NRPE
dependent_host_name $self
dependent_service_description DISKS,SWAP,USERS
execution_failure_criteria w,u,c,p
notification_failure_criteria o,w,u,c,p
}
Does anyone have an idea how to create something like that?

Re: [Nagios-users] Customising colours

My boss is wondering if there is some way to adjust the colour scheme so that when something becomes 'Acknowledged' it displays as blue, instead of red. So far I've changed the values for items such as .statusHOSTDOWNACK background-color to #33 in the status.css file, however it only shows that blue colour on certain windows, and not the Service Overview window which is our main one. Is what I'm trying to do possible? I only have a passing knowledge of css and html, so if it requires an extensive re-write it's probably not going to be practical. Hi, May be you can try another theme for Nagios: http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F1723.html;d=1 http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F2969.html;d=1 http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F2737.html;d=1 Regards -- Cédric Temple | Chef de Projet -- Unfortunately those theme's have the same problem, and my feeble attempts at editing them only solve half the problem. In the HostGroup Overview page, it still highlights the Down but Acknowledged host as red, when I edit the status.css file so that any line that references something as being acknowledged shows blue, it only shows that blue on particular pages. Interestingly, on the Host Detail page, where it lists every host in a large table, the hostname part of the line is still red, but the rest of the info (last check, duration, info etc) is highlighted in blue. And it's the hostname part of the display in the Hostgroup overview page that I'm trying to get blue. Would what I'm asking for require a total rewrite of how the acknowledgments are referenced in the web interface?

[Nagios-users] Voice Alerts
Hi Group, Has anybody successfully got voice alerts working on Nagios whether it be through a hosted company or other. I have my mail alerts working fine, they escalate to SMS and if the fault is still there I would like it to call up-to 3 different mobiles and play an alert through another escalation step, I'm not bothered if its a pre recorded message or one that is converted and synthesised. If need be I can use our Asterisk box to make the outgoing calls, but at the minute I can not find any solution via Google, maybe I'm searching for the wrong phrase. Once I have this working then I have a complete system up and running that my bosses are happy with. Thanks and looking forward to you replies.

Nothing in cgi.cfg *restricts* what can be seen. The parameters here
only grant full access to particular types of objects.
The OP needs to look at the docs for enabling authorization for the
CGI's. That will allow him/her to restrict based on contact settings.

Re: [Nagios-users] Nagios Web interface show hosts/services status to specific/contacts user only, not all hosts/services
Hi Marc,
You are right. we can not restrict to look all hosts/services in Nagios
web interface by modifying cgi.cfg file. can you please share any related

Nothing in cgi.cfg *restricts* what can be seen. The parameters here
only grant full access to particular types of objects.
The OP needs to look at the docs for enabling authorization for the
CGI's. That will allow him/her to restrict based on contact settings.

What you want is like what you put in the example above but you want to change
it to
define servicedependency {
host_name *
service_description NRPE
dependent_host_name *
dependent_service_description DISKS,SWAP,USERS
execution_failure_criteria w,u,c,p
notification_failure_criteria o,w,u,c,p
}
also you may want to change the notification criteria to a more suitable like
c,w,u ( that means in
the case of the NRPE being critical , unknown, or warning , you will not get a
n alert) .
you can also do it with hostgroups
define servicedependency {
hostgroups_namegroup1,group2
service_description NRPE
dependent_hostgroups_name group1,group2
dependent_service_description DISKS,SWAP,USERS
execution_failure_criteria w,u,c
notification_failure_criteria o,w,u,c

[Nagios-users] Binding Nagios to a single domain
Hello, I have installed Nagios on a machine which has more than one domain; all is working fine, but I reach Nagios login form from all domains hosted in the machine. I'd like to set Nagios in the way that it will be accessible only via one specified domain (for example testingtools.mydomain.com/nagios) and absolutely not from others; it is possibile? If yes, how I can make this? Another question: it is possible to switch Nagios first page (immediately after the login) to a specified one (for example the tactical view)? Thank you in advance!

[Nagios-users] What are the reasons to use NRPE?
Hi all I just wonder what the reasons are to use NRPE in favour of checks over ssh with ssh keys. To me, NRPE seems just one more piece of software that may potentioally be broken and more hassle with firewalls. Why do people still use it when ssh checks are just as simple and (in my opinion) far more secure?

Configure your webserver accordingly. It's hard to guess how you set it up to serve multiple domains, but the mechanisms apply when you want to configure the access to nagios. Most likely you have a /etc/httpd/conf.d/nagios.conf which defines scripts and aliases. Those are apache-wide defined and not bound to a special virtualhost. Move the definitions of nagios.conf inside the virtualhost definition of your choice and nagios will only be served there. > Another question: it is possible to switch Nagios first page (immediately > after the login) to a specified one (for example the tactical view)?

Therefor a check_by_ssh check takes longer then a check_nrpe check. This _is_ significant if you are running 2k checks per minute like me and some other people. Lots of check_by_ssh checks slow down the machine by a big degree and check latency will skyrocket.

Hmmm, you're right, this is indeed working. Didn't think so, because
my first tests failed, but after all, it looks like there were some
other configuration mistakes in it.
However, given the above example, wouldn't that mean, that - if I
define two hosts named web01 and web02 for example - that if the nrpe
check on web01 fails, it would also suppress DISKS notifications of
web02 ? I'm not sure how this is handled internally by nagios to
prevent such scenarios ... and I think it wouldn't be good if a full
disk on one of the servers wouldn't generate notifications if another
host's nrpe daemon check is suppressing this.

Yes. Obtain the URL for the page you want displayed (by right clicking on the link to it and 'copy link location' for example).

If you search back through recent lists there was some talk of using ssh connection master which will make SSH greatly faster than NRPE. As for security...not so much. Both (can) use the same encryption algorithms. What really differs is SSH uses asymmetric encryption to setup the shared keys whereas with NRPE you give it the shared key (hence NRPE being faster, for the most part). A shared key VS a certificate I'm not feeling a real win with either side. In one case I need to grab a config file, in the other I need to grab a ssh-key file... The default to setup NRPE with explicit commands vs just allowing a user to run arbitrary over SSH, NRPE comes out ahead here. But its not really any harder to setup SSH so each key corresponds to a particular check. And you can setup NRPE to allow you to execute any command, which defeats the initial security you gain by limiting which commands it can run. As for having passwords on your keys and loading up a ssh-agent...pffft. If I can read your private key, I can read your ssh-agent socket and the unencrypted SSH key stored in RAM from said ssh-agent process. The latter might actually be easier if we want to go down the road of silly security (think firewire and DMA) since the agent process is always going to be in RAM... .r' -- Register Now & Save for Velocity, the Web Performance & Operations Conference from O'Reilly Media.

Apparently wilcards for the names of services can be used [1] although I
am not sure if also it is possible to be done for the hostnames. Will
wildcards (or .*) be valid with Nagios 3.0.6?
These are the definitions that I was thinking to use:
define hostescalation{
host_name *
first_notification1
last_notification 3
escalation_period none
notification_interval 60
contact_groupsadmins
}
define hostescalation{
host_name *
first_notification4
last_notification 0
escalation_period none
notification_interval 60
contact_groupsadmins
}
define serviceescalation{
hostgroup_name
linux-servers,solaris-servers,windows-servers
service_description *
first_notification1
last_notification 3
notification_interval 60

}

You could even publish it on a public Web site without compromising your security. With a shared key, a hacker that gets a hold of either end of the connection has compromised the connection, and you wouldn't even know it. If all the clients use the same shared key, a hacker would even compromise the whole network. With a public ssh key, the connection remains secure even when the SSH server is compromised (with NRPE, the SSH server is of course the monitored host). Only when the private key is stolen (which should never be on the SSH server, only on the client - which in this case is the single central Nagios server) do you have a compromise. The second security benefit of SSH is that every time you connect, it uses a different shared key for the actual connection. With a shared-key file, you would be using the same shared key for months. In a pinch, with SSH, you could even use the same private/public key pair for all monitored clients and still only moderately compromise security. With a shared-key file, if you use the same shared key for all clients, a hacker who compromises any of the machines in the network has full control over everything. Not what you'd want to see. > The default to setup NRPE with explicit commands vs just allowing a > user to run arbitrary over SSH, NRPE comes out ahead here. SSH also has the capability to restrict what commands you can execute; you can specify it in the authorized_keys file on the client. In fact, I sometimes establish a (semi-)permanent tunnel by forwarding some ports via SSH, and prohibit executing any commands on the remote end. Here is a line from the authorized-key that I use to lock down on one of my servers to only allow forwarding a few ports (in this case, for mysql and LDAP), and not execute any commands at all. > from=" IP>",no-X11-forwarding,no-pty,permitopen="localhost:3306",permitopen="localhost:389",command="/bin/true" > > ssh-rsa But its not really any harder to setup SSH so each key corresponds to a > particular check. The problem with that is both performance and maintenance. In Sean's example, you have 220 hosts and 1550 active checks. That means managing either 220 key pairs (or if you aren't too concerned, you can get away with a single key pair), or 1550 key pairs if you use one for each check. You also defeat the master-connection approach suggested earlier. > And you can setup NRPE to allow you to execute any > command, which defeats the initial security you gain by limiting which > commands it can run. > > As for having passwords on your keys and loading up a > ssh-agent...pffft. Agreed on that. Just leave the private keys without a passphrase and store them in a well-protected location. The agent would defeat the whole point of having a passphrase on the key anyway, AND, as you point out, make it available through a well-documented interface in RAM. And it makes rebooting th

http://wiki.bacula.org/doku.php?id=howtos There are two HOWTOs there. I wrote the one for the passive checks. Somebody else wrote the one using active checks, which I believe actually queries the database. Eduardo Barreto wrote: > Hi all, > > Does anybody know how to check a Bacula Server?

[Nagios-users] Monitor file size through nagios
Hi, I am aware of monitoring disk space using nagios (disk partitions --> check_disk). Now, I have a situation that I would like to monitor size of an individual file through nagios. Ex, /var/log/custom-snmpd.log -- > this file will grow very fast and i would like to monitor if the size of this file crosses 1.5 G Is there anyway we can do this?
