[Nagios-users] GUI front in for nagios.
Hi, Does a client exists that runs on Linux, Windows, and Macs that can poll a Nagios server and display information about the servers rather than using the web interface? - Using Tomcat but need to do more?

[Nagios-users] NSCA only accepts first check
Hi all, I'm trying to configure nsca, and I've run into a problem: NSCA only accepts the first passive check that is sent to it, and all subsequent checks fail. first check: [18:05:02]$ echo -e "vmp161.vampire\tMyrinet Connectivity\t0\tBLAH\n" | ./src/send_nsca -H monitor -c nsca.cfg 1 data packet(s) sent to host successfully. second try: [18:11:29]$ echo -e "vmp161.vampire\tMyrinet Connectivity\t0\tBLAH\n" | ./src/send_nsca -H monitor -c nsca.cfg Error: Timeout after 10 seconds After restarting the nsca daemon on the monitoring host, it will again accept a single check, and all subsequent checks will timeout. The nsca.cfg on the remote host has only a password entry. Here are the relevant bits from the nsca.cfg on the nagios server(monitor): pid_file=/var/run/nsca.pid server_port= server_address= nsca_user=nagios nsca_group=nagios debug=1 command_file=/var/log/nagios/rw/nagios.cmd alternate_dump_file=/var/log/nagios/rw/nsca.dump aggregate_writes=0 append_to_file=0 max_packet_age=30 password= decryption_method=1 Any help would be appreciated.

Yes, The service_check_timout in nagios.cfg is a last-resort timeout. If a plugin hasn't terminated itself in that period of time then nagios will kill it. All of the standard plugins (I believe) can be passed a timeout value in their command line, usually via -t. If none is passed they'll use whatever value is hard coded (usually 10 seconds). You can use '--help' for the plugins you use to see the timeout parameters. > I know that I should work on my dns first, but I want to understand what > decisions Nagios makes there.

[Nagios-users] servicegroup shortcut in servicedependency doesn't quite work that way in the code?
If one attempts to specify the following in Nagios:
define servicedependency {
servicegroup_name X
dependent_host_name Y
dependent_service_description Z
execution_failure_criteria w,u,c
notification_failure_criteria w,u,c
}
it generates the error:
Error: Could not expand master hostgroups and/or hosts specified in service
dependency
(config file 'config.cfg', starting on line
If I'm reading the code correctly in xodtemplate.c it looks like the code
starting
at line 4119 should consider the possibility that no hosts/hostgroups are
specified
even though a dependent host name is, and allow a fall-through to the code at
line
4179 which appears to be designed to handle just this case.

Re: [Nagios-users] ocsp slows nagios a great deal
Not sure if this was discussed (I didn't find later threads), but I would suggest that you need to batch your send_nsca requests. Realize that *every* transaction that nagios does invokes OCSP if it is defined. This means there is a fork, exec, and then whatever that app does. If you have a perl ocsp script for example, perl has to compile that script, execute your code, and most likely then fork/exec send_nsca. Send_nsca has the ability to accept batch input. I streamline my ocsp script so that the data is batched up in a file that at some point later in time will be sent using send_ncsa. Given that you have a good number of checks, nagios is making the ocsp call very frequently. You can use that to your advantage. Each time you run your script: 1) stat the queue/batch file (if it exists) 2) flock the batch file (if it exists) 3) If it is older then an acceptable amount of time (make this a configurable parameter), set a flag to remember you will be pushing the data on this iteration. 4) If the file is larger then an acceptable size, set your flag again. 5) write your ocsp args to the end of your batch queue file. 6) if the flag is set, run send_nsca and pipe your batch queue file into it. 7) truncate the file to zero length 8) unlock it You will dramatically cut down on the send_nsca fork/exec's and you will also cut down on the network traffic and system noise that you create as a result of making so many connections. Go back over your code and streamline it. An alternate implementation could be to start a perl demon that does 1-8 that reads from a FIFO and simply make your OCSP routine an "echo $@ >>fifo" You could also then have the perl program wake up more regularly and flush the queue rather then having to rely on the next OCSP request to come through (you could also use a cron job or a nagios plug-in to periodically flush the queue by making the ocsp command both a plug-in and ocsp compatible, simply call the OCSP command with a zero timeout to cause the flush and allow null args which would skip adding them to the queue when called as a plug-in) -FredC - Original Message From: loren jan wilson <[EMAIL PROTECTED]> To: nagios-users@lists.sourceforge.net Sent: Friday, August 11, 2006 10:38:31 AM Subject: [Nagios-users] ocsp slows nagios a great deal dear nagios users, I'm in the process of trying to set up a distributed nagios environment monitoring about 9,000 services on 2,500 hosts. i'm using Sunfire V210 servers running Solaris 10. i've found that the distributed servers which monitor the active services can run about 1700 checks every 5 minutes if ocsp isn't enabled, but once I enable ocsp, the number of active checks I can do goes WAY down. here's a breakdown: - ocsp disabled: 1700 checks / 5 min. - ocsp command set to /bin/true: 1200 checks / 5 min. - ocsp command set to a perl program that forks, then pipes output to send_nsca: 800 checks / 5 min. - ocsp command set to a shell program that pipes output to send_nsca: 500 checks / 5 min.

Re: [Nagios-users] submitting external commands remotely
Hi, I doubt you can use sockets over NFS, someone correct me if i am wrong. What you could do is to execute the script on the nagios host, via ssh. If you normaly do this on the nagios host: scheduledowntine.sh host ServerA 13:00 14:00 You could do this on a remote machine: ssh nagioshost "scheduledowntine.sh host ServerA 13:00 14:00" You would be prompted for a password every time you do this, but you could use rsa/dsa keys, then there would be no need to enter a password each time. Safe and simple :) Cheers, Peter Iphtashu Fitz wrote: I have a handful of scripts that I've written that submit commands to our Nagios monitor remotely, so I'm pretty comfortable with working with external commands.

[Nagios-users] Web Event Log View can crash IE?
Hello List, I just wondered whether I'm alone in having the Web "Event Log" sometimes appear to make IE stop responding (need to do forced close of IE). This is most evident when attempting to view an earlier log than the one being displayed, but often occurs on the current event log too. I don't get the problem with Firefox, but I do get it with IE (on multiple client systems). I've had the problem with Nagios 2.4 & now 2.5. Thanks Giles - Using Tomcat but need to do more?
