Re: [Nagios-users] Looking for a plugin to check print spool queues on Windows 2003 server.
2009/4/23 Matthew Stier matthew.st...@us.fujitsu.com: I've adapted a Perl script to do a per-queue check of Solaris print server. I'd like to have the same functionality for my site's Windows 2003 print server. There seems to be a plethora of CPU and DISK plugins, but nothing as simple as checking the status of a printers queue size. (Or that the queue may be stuck. [Same job a the top of the stack after 'X' checks.]) At my site all Sun and Linux workstations print jobs are routed to a single Unix print server, and then to the network attached printers. Dittos for the Windows side. There are various performance counters in Windows which you can query using NSClient++, nc_net or whatever. In my nsc.ini (NSClient++) config for example, I have: PrintQJobsSpooling=inject CheckCounter Counter:jobs=\Print Queue(_Total)\Jobs Spooling ShowAll MaxWarn=10 MaxCrit=25 PrintQJobs=inject CheckCounter Counter:jobs=\Print Queue(_Total)\Jobs ShowAll MaxWarn=250 MaxCrit=500 PrintQNotRdyErrs=inject CheckCounter Counter:queues=\Print Queue(_Total)\Not Ready Errors ShowAll MaxWarn=25 MaxCrit=50 Although looking at my graphs, I'm not convinced I've ever seen anything useful from the Print Queue(_Total)\Not Ready Errors counter. hth, Jim -- Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.

[Nagios-users] Host shows down due to ping block on firewall
Hi All, I have started to do monitoring of some hosts which are behind the firewall and PING (ICMP) is block on firewall. so I have exculded ping service in localhosts.cfg file and as well as check-host-alive option also from host template but still Nagios web interface shows host as DOWN RED Color in host status web interface. I think this is happening due to PING block on firewall. However ssh and nrpe port are opened on firewall to do monitoring of host resources. other services are showing OK in green color associate to this host. Please let me know how can we enforce nagios to shows that HOST is UP in host status web interface.

Re: [Nagios-users] scripts in python
Make your script executable whith (chmod +x your_script.py)
And declare a nagios command like this:

define command{
command_namecheck_blabla
command_linepath_to_python_bin $USER1$/your_script.py $ARG ...
}
(path_to_python_bin is optional since your script is executable)

Can anybody tell me how I use domains names instead of IP address in the

}
And my hosts.allow looks like

#
nrpe: 17.0.0.1 monitor.domain.co.uk
But I'm still getting Could not complete SSL handshake, is the above
configuration correct or can I not use domain names instead of IP's

[Nagios-users] Multiple host service detail on one page
Hi All, I was wondering if anybody had anything place to see multiple hosts services on one page. For example I'm monitoring 3 individual exchange servers. I can add these to a hostgroup then check each individually : http://SERVER/nagios/cgi-bin/status.cgi?host=HOSTNAMEstyle=detail http://SERVER/nagios/cgi-bin/status.cgi?host=HOSTNAME2style=detail http://SERVER/nagios/cgi-bin/status.cgi?host=HOSTNAME3style=detail Is there any way to have 3 different host details such as the above but on one page ? So I can have a quick glance of exchange 1, 2 and 3 Thanks in advance, Nick http://SERVER/nagios/cgi-bin/status.cgi?host=HOSTNAMEstyle=detail Connaught plc is one of the UK's top 250 companies on the London Stock Exchange and the leading provider of integrated services operating in the compliance, social housing and public sector markets.

You have to adjust the olny_from line, your hosts.allow allows 17.0.0.1 to
connect to nrpe, but xinetd rejects the request, because you just allows
connections from 127.0.0.1 (or is there the 2 missing in the hosts.allow
line?)
you can simply write the domain name to only_from.
If you use the hosts.allow you could even exclude the only_from line from the
xinetd configuration by setting 3 in front of the line.

Christian

You have to adjust the olny_from line, your hosts.allow allows 17.0.0.1 to
connect to nrpe, but xinetd rejects the request, because you just allows
connections from 127.0.0.1 (or is there the 2 missing in the hosts.allow
line?)
you can simply write the domain name to only_from.
If you use the hosts.allow you could even exclude the only_from line from
the xinetd configuration by setting 3 in front of the line.

As I've written in the first mail, hosts.allow is the first instance which
looks if the IP is allowed to connect to this service, then xinetd looks at
the only_from and compares the IPs.
Your only_from contains just 127.0.0.1, thats localhost, nothing else as your
server itself is allowed to connect to nrpe.
This has nothing to do with nagios/nrpe, please read about networking, xinetd,
and linux in generall if you are not familiar with it.

But I'm still getting Could not complete SSL handshake, is the above
configuration correct or can I not use domain names instead of IP's
You have to adjust the olny_from line, your hosts.allow allows 17.0.0.1
to
connect to nrpe, but xinetd rejects the request, because you just allows
connections from 127.0.0.1 (or is there the 2 missing in the hosts.allow
line?)
you can simply write the domain name to only_from.
If you use the hosts.allow you could even exclude the only_from line from
the xinetd configuration by setting 3 in front of the line.

Christian

[Nagios-users] NLG but first..
Hi group, I'm a new user here so first of all I would like to thank you for providing this group for us all to ask questions and hopefully down the line reply to them too, I would also like to say what a phernominal tool Nagios is, I can not beleive how powerful it is and its free to boot; amazing. OK on with my first question. i'm up and running in 15 minutes as suggested (no bull), I have host being monitored along with a number of servers too, my alerts are set up and its just sitting there happy as Larry, What I'm after doing is separating users out along with their Server, I want user A to be able to see Hosts A but not allow User B to ba able to see Hosts A. I have heard that Nagios Looking Glass is the way to go but as the site is down I can not gather any information from there, I beleive from various posts that it users filter but I'm not sure if these filters are what I need, does anybody know if NGL is the add-on I need and that the filters will work for me or is there a different solution out there that I could use.

Re: [Nagios-users] Firewall Rules
It would seem obvious, but there are no minimum required firewall rules. You simply need to open a firewall hole for the remote server for every service you plan to monitor by the HQ machine. If you are monitoring the remote host via ICMP and SNMP, then you need to open up those two holes on the remote firewall. If you are using NRPE on the remote host, you'll need to open that as well, etc, etc. By default, most folks monitor their host-alive states using check_ping (ICMP), so at a minimum you'll need to open up ICMP on the remote to allow the HQ box to ping those hosts. This assumes that all outbound traffic is allowed from each host and that your HQ box is behind a firewall that performs stateful inspection (which is helpful for things like DNS, etc) James Moseley Gabriel - IP Guys gabr...@impactteachers.com wrote: Dear all, I’ve got my Nagios server up and running, and for some reason, I cannot get the two servers, NagiosHQ, and RemoteServer, to talk to each other.

Re: [Nagios-users] only_from = 127.0.0.1
Top-posting means that you put what you have to say at the top of the reply the way I do it here. Bottom-posting means that you put your reply below the original message. Which of the two styles is preferred is largely a matter of personal taste, rather than right or wrong, actually*. Both have advantages, and some people tend to get very passionate about their particular style. I have seen moderators on both sides of the issue admonish members don't top-post or don't bottom-post. In the original Internet culture, bottom-posting was preferred, and some people still like it better. Bottom posting makes most sense when you combine multiple thoughts in a single post, and want to be able to respond to each one individually. In my mind, most of the time top posting actually is better because the reply stands out more than the original question - which usually is what you want. The majority of mailing lists that I am on seems to have switched to primarily top-posting, though, and most of the big email programs make it quite difficult to do bottom-posting. When you hit Reply, the cursor is usually positioned at the top of the page, not at the bottom. My personal rule: if there already is a longer thread, stick with whatever style it has. The one thing you don't want to happen is having to look for the next reply because somebody switched style in the middle. If there is no pattern to follow (such as in this case), and I only want to respond to a post as a whole rather than individual points, I use top posting. * technically speaking, there is a still-valid RFC that specifies bottom-posting, but in practical terms it has been obsoleted by history.

[Nagios-users] Permissions problem
Hello List, I'm using Nagios and NRPE to monitor some system logs on a remote system via check_logfiles. Here's the setup: -user 'nagio's is part of the 'adm' group -/var/log/syslog is readable by the 'adm' group -manually executing check_logfiles as nagios (sudo -u nagios ./ check_logfiles etc) works -executing remotely via NRPE fails -NRPE is being started via xinetd and running as 'nagios' changing syslog to be world readable fixes the problem, however it does just that; leaves the syslog file world readable. This behavior is being repeated for several other log files as well (mysql, apache) where despite nagios being part of the appropriate groups still not remotely readable. This is clearly a problem of something running as a different user.

Re: [Nagios-users] NLG but first..
Hi Craig, Thanks for the reply and for the welcome.. I like the look and feel of NLG 110, the more I look at it the more I like it, I have mailed Andy asking for help on the filters as their was no documentation with this verion, however with his site being down I don't hold out much hope of his return mail. I'm still around, I've been busy on some other projects so my personal website had taken a back seat unfortunately and when the database server died a few weeks ago I didn't see much point in reviving it. I keep meaning to put a page up to redirect people to Nagios Exchange for NLG until I get around to putting up a new version of the site. I don't recall having received any e-mails off you but they may not have been getting through before the database server went pop! Anyway feel free to e-mail me off-list (remove -lists from my mailing list e-mail address.) Has anybody in this group got the filters working at all. If you describe what you're looking to achieve with the NLG filters I'll guide you as best I can. I'd recommend reading the filters-howto.txt file in the root of the NLG distribution and examining the samples in the server/sync-files/s3_filter.inc.php and server/sync-files/s3_filter_auth.inc.php files. If you're looking to restrict users to certain hosts/services/filters, you'll also need to have enabled Apache authentication for both the NLG server and client.

Re: [Nagios-users] Permissions problem
By the way, for further info see the xinetd man page, which (on my system, anyway) states: group determines the gid for the server process. The group name must exist in /etc/group. If a group is not specified, the group of user will be used (from /etc/passwd). This attribute is ineffective if the effective user ID of xinetd is not super-user. Note that it's only going to use the primary group. Other group rights are dropped. On Thu, 23 Apr 2009, Adam Mooz wrote: No, it's not, but that doesn't matter.

Any ideas?
Need expert advise please.

Hi all,
Hoping someone can give me guidance on this.
I'm trying to set-up monitoring on our routers in which I already followed
this doc:
http://nagios.sourceforge.net/docs/3_0/monitoring-routers.html
I'm doing snmp at this point and trying to define the service to my hosts
then I get this error when verifying:
Error: Service check command 'check_snmp' specified in service 'PING-NET' for
host 'cisco-router' not defined anywhere!
Here's a sample of my cfg:
define service{
use local-service ; Inherit
values from a template
host_name cisco-router ; The name
of the host the service is associated with
service_description PING-NET ; The service
description
check_command check_snmp!-C public -o sysUpTime.0
; The command used to monitor the service
normal_check_interval 5 ; Check the
service every 5 minutes under normal conditions
retry_check_interval1 ; Re-check
the service every minute until its final/hard state is determined
}
Any ideas?

Thank you!
Each check_command you use needs to also be defined in your
configuration somewhere:

[Nagios-users] SNMP Service Uknown
Hi all,
I got the first part set-up on monitoring my network equipment.
Ran the verify and everything was OK.
However when I go to the Nagios page, I see these logs in my network equipment:
SNMP problem - No data received from host
This is the notification email I got:
Notification Type: PROBLEM
Service: PING
Host: CISCO
Address: 172.168.2.1
State: UNKNOWN
Date/Time: Thu Apr 23 21:29:00 EDT 2009
Additional Info:
SNMP problem - No data received from host
This is a sample of my cfg file:
define service{
use local-service ; Inherit
values from a template
host_name cisco-router ; The name of
the host the service is associated with
service_description PING ; The service
description
check_command check_snmp!-C public -o sysUpTime.0
normal_check_interval 5 ; Check the
service every 5 minutes under normal conditions
retry_check_interval1 ; Re-check the
service every minute until its final/hard state is determined
}
Not sure on this but is there anything in the router/switch that need to
enable?
I'm sure it supports snmp.
Please advise.
Thanks!

Yes, you'll probably need to configure your router to accept SNMP polls
from your Nagios box.
