[Nagios-users] Monitoring Performance: Not sure what is good or bad
Below is a snapshot of monitoring performance as shown on the Tactical Monitoring Overview Page Monitoring Performance Service Check Execution Time: 0.04 / 14.14 / 3.036 sec Service Check Latency: 0.00 / 85.15 / 9.604 sec Host Check Execution Time: 4.30 / 16.05 / 8.263 sec Host Check Latency: 0.02 / 112.41 / 30.940 sec # Active Host / Service Checks: 43 / 244 # Passive Host / Service Checks:0 / 0 Now, I know that I'm not monitoring that many hosts, but I'm not sure what 'good' performance is. My nagios server had an extremely high load this morning, and the only service on that box, is nagios. What type of performance should I reasonably expect from my monitoring server?

[Nagios-users] How to graph historical data
Dear All, I would like to know if it's possible to graph the historical data that Nagios produces - I am about to rebuild an old Linux box that has nagios installed on it, but I would like to at least see some trends what actually has been going on. I'm in the rare position where nothing on my network has so much as farted in the last few months, so I'd like to see those trends which we don't notice through everyday usage. --- Kind Regards, Mr Gabriel -- Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!

Re: [Nagios-users] Create a template host. Howto?
Just to clarify, and I thank you and all who replied for taking the time. It's easier to create hostgroups, and assign checks to the host groups, then assign the hosts to those same hostgroups, in order to make sure for example, all linux based servers have their uptime, swap space, SSH, and free disk space all checked? If my understanding is correct, a host can belong to many hostgroups? In which case, a host that is running a webserver, mysql server, and FTP service, will be checked for those services not by its host definition, but by its host group definition? I half hope that I'm not right, because it means I have to reconfigure all my host defs! --- Kind Regards, Mr Gabriel -Original Message- From: Andy Shellam [mailto:andy-li...@networkmail.eu] Sent: 10 May 2009 14:24 To: Gabriel - IP Guys Cc: nagios-users@lists.sourceforge.net Subject: Re: [Nagios-users] Create a template host. Howto? Gabriel, From experience, you're better off using host groups. For example all your hosts will have certain checks (ping, disk space etc) so I have a group all hosts which all hosts are added to. We also have hosts that perform their own functions - e.g. database servers, DNS servers, web servers, which all have relevant checks of their own. So we have other host groups called, for example, DNS servers, web servers etc which each host is added to the group depending on the function it performs. All service checks are then added to the host groups, instead of individual hosts. Then if we come up with a new service check, it gets added to the host group it needs to be in, and is automatically added to all hosts in that group. Similarly if we add a new server, it gets added to the host groups it needs to be in, and inherits all the service checks of that group without any additional configuration.

[Nagios-users] Nagios Monitor Server, and NRPE clients, giving funny results
Dear All, I'm trying to get my Nagios instance to behave properly! It seems to be monitoring my servers just fine, but for some reason, all my servers, which are different from each other show the same swap space, and the same free disk space to within 10 megs. Now the above tells me that there is a config error somewhere. In order to test this, I log into my monitor server, and issue the following command; ./Check_nrpe -H client_ip -c check_disk 50 80 My understanding tells me that the following happens * The check_nrpe plugin on the nagios monitor server runs, and accesses the client at client_ip * It initiates its local check_disk plugin with the parameters of 50 and 80. * This causes the check_disk plugin on the client to run, as if typed locally in this manner check_disk -w 50 -c 80 Running check_disk 50 80 on client_ip returns data on the disk state Running ./Check_nrpe -H client_ip -c check_disk 50 80 on Nagios monitor server returns unknown argument I cannot figure out what is causing this discrepancy - check_nrpe -H client_ip returns Nagios version so I know the communication works.

Re: [Nagios-users] Nagios Monitor Server, and NRPE clients, giving funny results
I get the concept, NRPE is installed on my client servers, and nagios itself is installed on ate server designated the monitor server. This server itself also has NRPE installed as it's monitored by a separate nagios install, but that's above and beyond this issue. I've been told that I cannot pass arguments to NRPE from the monitor server. For example, check_nrpe -H client_IP check_disk - is the most that I can issue on the monitor server. I guess this then means that in the *.cfg files on nagios, everywhere it says check_nrpe!check_disk - there should be no arguments after it? If this is the case, then I think I found where the guy I replaced made a mistake! -Original Message- From: Assaf Flatto [mailto:assaf.fla...@ssp-intl.com] Sent: 08 May 2009 11:00 To: Nagios User list Subject: Re: [Nagios-users] Nagios Monitor Server, and NRPE clients,giving funny results Gabriel I believe you may be confusing the two components .

[Nagios-users] NRPE/Firewall issues: Assistance required.
Dear All, I've managed to install my Nagios server (monitor), and it seems that all is well with it. The box to be monitored(client) has NRPE running on it. On monitor, I run $ CHECK_NRPE -H *client ip* I get the CHECK_NRPE: Socket timeout after 10 seconds error message On client I've run the command $ iptables -A INPUT -p tcp -dport 5666 -j ACCEPT This should allow all traffic directed to port 5666 to be accepted, which in turn should kick NRPE into life and have it return NRPE v2.12 I can't tell what I'm doing wrong here - as I'm sure I've done the right thing. Any advice on getting client talking to monitor via NRPE, things I should think about that could scupper the process would be appreciated. --- Kind Regards, Mr Gabriel -- Register Now Save for Velocity, the Web Performance Operations Conference from O'Reilly Media.

[Nagios-users] Any firewall gotchas for NRPE?
I've just finished configuring a Nagios instance, and I have also install NRPE locally on the same machine. I have configured NRPE and checked that it's working by running the following, # /usr/lib/nagios/plugins/check_nrpe -H 127.0.0.1 NRPE v2.12 The result comes back as expected. Also, checking swap returns the following. # /usr/lib/nagios/plugins/check_swap -w 20% -c 10% SWAP OK - 100% free (1983 MB out of 1983 MB) |swap=1983MB;396;198;0;1983 So I know that NRPE itself is working, what I can't figure out is why Nagios not giving me the extra data, I just get the error msg CHECK_NRPE: Socket timeout after 10 seconds.
