[Nagios-users] Query on check_http timeout option
Hello, I want to understand the timeout option in check_http. From the help option, it states : -t, --timeout=INTEGER Seconds before connection times out (default: 10) I monitor a webservice to check for connectivity and also pass some parameters to get some content back. Usually the download transfer takes around 20 seconds and occasionally it takes well over a minute or two. I have configured my check in this fashion. $ROOT/libexec/nagios/check_http -u 'some URL' -I API Hostname -t 10 -c 20 -p 4080 -A 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; pagechecks mon)' I am seeing the check error out with the message 'Socket timeout after 10 seconds' quite often. When I manually connect ( telnet/curl) the URL the connection time is well below 10 seconds. Is the timeout parameter used to check the time it takes to establish a TCP connection or to govern the time the check took to complete ?

I believe it is the time the check_http took to connect, and download the page. Is the total time when you manually connect using curl greater than 10 seconds?

But the check times out in the host ( passive check). Nagios has never complained of not receiving info from this check ( UNKNOWN) state. My concern is whether the timeout in check_http applies to only the connection part in establishing a TCP connection or the overall completion of the check ( time to connect + connect download .. ) .

Re: [Nagios-users] a bit [OT] PNP4nagios help
Thanks for the help , but managed to solve the issue .
The problem was that the pnp4 was looking in the wrong place for the rrd
data provided by nagios .
Once i fixed the paths - the graph resumed their work.
Thanks for the nudge .

Hi Assaf,
Have you restarted nagios lately?
Have the permissions on the pnp4nagios files (or the directory they
reside in) changed?
Has anything changed in nagios.cfg that might affect this?
How are you running pnp4nagios? Synchronous mode, bulk mode or bulk
mode with NPCD? Are the nagios perfdata files being populated
correctly etc.?
Cheers,

When i execute the script manually - perl -d

Re: [Nagios-users] Large Installation
Nagios does have some scalability issues, but for the most part you won't run into them until you get to truly huge installations. I can see three main scalability issues: config file maintenance and the need for one central server, and firewall issues. Config file maintenance can be improved to some extent with careful design of the config files, as well as tools. It is an issue that I am running into with a relatively small installation with 80+ hosts and 400+ services. My installation is highly heterogeneous and very dynamic, which makes config file maintenance a nightmare. Having to restart Nagios after a configuration change doesn't help either. On the other hand, a network with 2000 identical machines is probably going to be much easier to manage than my type of network. The central server is an obvious bottleneck. No matter how powerful the machine and the network connection, there are only so many checks results it can handle. Fortunately, Nagios doesn't require much horsepower. Distributed monitoring helps with this issue because the most expensive part of Nagios is running active checks. With distributed monitoring, the active checks can run on multiple smaller boxes, and then send the check results back as passive checks. Of course distributed monitoring compounds the config file maintenance issue, because you have to configure each check multiple times. The third issue is not directly a scalability issue. Nagios is built with the assumption of a local and mostly trusted network. It's non-trivial to securely get checks to work on remote machines without pretty gaping poking holes into firewalls, and/or frequently establishing and tearing down encrypted connections with the attendant processing load. There are some third-party solutions for this issue, though.

[Nagios-users] Strange fluctuation in load average
Hi all, When I first installed nagios-3.2.0 with embedded perl enabled, nagios experienced increasing latency, starting at 1 sec and climbed upto 300 within a few hours until restarting nagios. I read on one of the older post suggesting to recompile nagios *without* embedded perl, and that resolved the latency issue, with latency consistently at less than 1 sec. However, ever since, the system load average has fluctuated wildly from 1 to 12 and down to say ... 3 within a minute. This fluctuation happens 3-10 minutes each time and calms down for ... say an hour. There doesn't seem to be any cron jobs that can cause this kind of load, and cpu (1-quad core) is usually at least 50% idle , with plenty of free memory, no IO blocks, on Centos 5-2. What's strange is with nagios compiled with embedded perl, the load was consistently at 2-4. Could this be nagios related? Please let me know if you need more information. -- Trisha Hoang | IT/Operations | Rockyou, Inc. | Phone: 408-472-3989 | AIM: rockyoutrisha -- ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.

The child then runs the check, updates that file and then creates a file with the same name, plus '.ok' in that directory, letting the parent process know the check is completed. So, take a look at the contents of several of those files, if you're lucky, you'll see that either they are for the same host, or the same service check. If so, there might be something in the way that host or service is getting polled that is causing the forked child to die.

Re: [Nagios-users] Large Installation
I can't say that I've solved the scalability problem, but I I don't have it, just because I've implemented a policy such that I never check any server over a WAN link, with the exception of another Nagios server (plus both ends of all of the WAN links themselves). This does require one Nagios server per site, but to me, that's an appealing idea anyway, because I don't have a single point of failure. Any of my Nagios installations could die completely, and I'd be alerted by the others, just like any one internet connection could die, and I'd still get alerts about it. In the event of a weird failure, I can pretty much construct the network diagram based on which links are reporting up, and from where. It does require a certain amount of configuration overhead, but most of that is done with templating anyway. I don't have my system laid out exactly like I want, but I'm implementing version control (subversion, in my case) and I have a different Nagios repository for each site. If I had more templates (or more shared configuration files), I would probably have a 'nagios-shared' repository, so I wouldn't have to replicate everything manually. As for the arrangement of my configs, it mostly follows this howto that I did a year ago: http://www.standalone-sysadmin.com/blog/2009/07/nagios-config/ Hope it can help someone --Matt On Thu, Jun 10, 2010 at 3:55 PM, Kevin Keane subscript...@kkeane.com wrote: Nagios does have some scalability issues, but for the most part you won’t run into them until you get to truly huge installations. I can see three main scalability issues: config file maintenance and the need for one central server, and firewall issues. Config file maintenance can be improved to some extent with careful design of the config files, as well as tools. It is an issue that I am running into with a relatively small installation with 80+ hosts and 400+ services. My installation is highly heterogeneous and very dynamic, which makes config file maintenance a nightmare. Having to restart Nagios after a configuration change doesn’t help either. On the other hand, a network with 2000 identical machines is probably going to be much easier to manage than my type of network. The central server is an obvious bottleneck. No matter how powerful the machine and the network connection, there are only so many checks results it can handle. Fortunately, Nagios doesn’t require much horsepower. Distributed monitoring helps with this issue because the most expensive part of Nagios is running active checks. With distributed monitoring, the active checks can run on multiple smaller boxes, and then send the check results back as passive checks. Of course distributed monitoring compounds the config file maintenance issue, because you have to configure each check multiple times. The third issue is not directly a scalability issue. Nagios is built with the assumption of a local and mostly trusted network. It’s non-trivial to securely get checks to work on remote machines without pretty gaping poking holes into firewalls, and/or frequently establishing and tearing down encrypted connections with the attendant processing load. There are some third-party solutions for this issue, though.
