I have installed nagios successfully also able to monitor windows hosts. but not able to monitor linux hosts. i have follow below procedure, installation part and evertything was ok.but still i am not able to see linux host under nagios. i followed below url for monitor linux hosts on nagios.URL...
View 3 Replies View RelatedIs this possible that a process running on a remote-host only inform nagios when some thing is wrong. Rather then nagios-monitoring-server checking through NRPE every so often. Reason is I want to add too many alerts in the application. And I don't want a whole list of ok messages.
View 1 Replies View RelatedI'm trying to setup my test nagios to check the disk space of another linux box. I've got it setup and checking. But to my surprise, it was checking the nagios server's local disk space instead of the remote linux.
Here is my services.cfg.
define service{
use basic-service
name disk-space
check_command check_local_disk!20%!10%! /

View 5 Replies View RelatedI installed Nagios following the Quick Install method from the Nagios.org web site but now I would like to add and monitor another host.I don�t find a way , I have for example replaced the ip number of the localhost(127.0.0.1 localhost.cfg) for another ip number and I am able to monitor another computer that way. But then I no longer MONITOR the localhost unless I replace the ip number in the localhost.cfg file. what I would like to do is to monitor both or more computers.

And they not be anle to access other group.
View 1 Replies View RelatedSince a week or 2 Nagios is constantly marking hosts (servers mainly but also a few Serial-over-IP converters) down for anything up to a few minutes. Typically, all services stay in OK status. Looking closer at a host in such state, it's status information is
CRITICAL - Packet Filtered (<IP address of host in question>)
in soft state. Sometimes services are in critical state with the host in OK status. Almost always the status information is "No route to host". Further checking shows no problems. Rarely this state lasts longer than one check interval. This started after a link was down, putting, correctly, all hosts and services on red for being unreachable. The link problems were solved within a few hours but Nagios only showed this after 2 reboots. Since then the problems has lessened in frequency gradually, from 5 to 10 of the 34 hosts being reported down at any given moment (the same for the 150-ish services monitored) to where I am now, 1 to 5 problem statuses (counting both hosts and services) and the occasional 'all green' screen. A week ago, when the problems were going a week already, Nagios updated from 3.2.0 to 3.2.1. This showed no apparent improvement.
Still, the Host Groups screen is not stable. A read or yellow status initially signified a problem to be looked at, right now it is likely a false alarm to will go away. Whenever the "packet filtered" or "no route to host" is followed up by a ping test, no problems, not even with the slightest delay or packt loss are found.

View 1 Replies View RelatedI believe that I need to disable the host check, I'm checking a public FTP service and ping is disabled on that FTP host. This is resulting in Nagios reporting the host as down, but the service shows as OK.
Is there any way to disable the host check?

View 14 Replies View RelatedMy question is about checking remote services under Nagios. I have installed nrpe and the standard plugins on my Nagios server (RHEL 5.4) and the systems I want to monitor. I have been able to create hostgroups. I am somewhat confused as to how to add a new service. I want to check to see if tomcat is running on the remote servers. I found a plugin check_procs. If I run the following command on one of the remotes it works.
Quote:
check_procs -u tomcat6
PROCS OK: 1 process with UID = 101 (tomcat6)[code].....
It doesn't work. I'm not sure how to format the service.I've found gobs of documentation on how to setup and install Nagios, done. I've not been so lucky on how to setup a new service.

Q=What will this do?
A=This will read from /root/Desktop/iplist (or anywhere you want to put the list) after it reads the ip it will ping the ip two times. If the remote host is up then it will write the ip to a log. If the ping fails it will display it on the screen, write the ip to syslog so that you can do remote logging, and last it will send the ip by email to a user or a group of users.
Code:
#!/bin/bash
#wrote by Zach Underwood feb-12-2011
#test and wrote on centos 5.5 with sendmail
rm -f /root/Desktop/iplog #This will remove the good iplog
exec 9</root/Desktop/iplist #put full path the file where ip list is. Make sure that the ips are listed one per line.
while read -u9 ip
do
ping -c 2 $ip > /dev/null 2> /dev/null # ping and discard output
if [ $? -eq 0 ]; then # check the exit code
echo "$ip is up" >> /root/Desktop/iplog #write the ip of the hosts that are up
else
echo "$ip is down" # will show on the screen the ips that are not up
logger -p auth.notice "$ip is down" # will write the down host to syslog
echo "$ip is down" | mail -v -s alert user@anydomain.com > /dev/null 2> /dev/null #will send mail users about host down

Is there a way to monitor a wall outlet with nagios.I want to check if we got some power out of a wall outlet.This is to check whether we are running on the electricity network or on our diesel power generator.The wall outlet is connected only to the electricity network, so if there is no more power coming out of the outlet that mean that we are running on the diesel power generator.
