I think i foregot to explain a crucial point that nagios is running in my router not in my machine. If i had told u my machine, then I really apolagise for stealing your precious time. And is there anyway that I can trigger the check_uptime (plugin written by me) all the time when the router is up???. If so please do tell me. If the router is down and nagios doesnt run then its ok for me. Since that is a different issue. But from your reply I came to understand that check_uptime will be called for the first time when the nagios is started and then if any of the services fails then again the check_uptime is called.

You're getting the difference in the uptime output in Nagios and the console because Nagios hasn't run the uptime command for the host for over a day. If you're not retaining status information, then when you restart Nagios, it re-runs all it's checks, hence why it then gets updated. After that it is only run when a service fails. What I still don't understand is how your uptime command ensures the router is up? If the router is not up, then Nagios won't be running (as you're running it on the same host) so it seems quite pointless really. If the Lanlink checks that the LAN interface is up and connected - that makes sense, but then a check_ping to <a href="http://127.0.0.1" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">127.0.0.1</a> as your host check_command would give the same result as the uptime, then you could have an "Uptime" service with your check_uptime command. That way you could be confident that the status detail in Nagios is reasonably up-to-date.

I have my router in which nagios is installed. I have to monitor a few services like Lanstatus of net1 interface, Webserver, and DNS. Well now for this I have a host.cfg and services.cfg file where I had configured this way: Host.cfg define hostgroup{ hostgroup_name Enpaq alias Enpaq members sujith } define host{ host_name sujith alias Enpaq Router address <a href="http://127.0.0.1" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">127.0.0.1</a> max_check_attempts 1 check_command check_uptime check_period 24x7 contact_groups admin notification_interval 0 notification_period 24x7 notification_options d,u,r,f } And services.cfg define service{ host_name sujith service_description LAN LINK check_command check_link!net1 max_check_attempts 1 normal_check_interval 1 retry_check_interval 1 check_period 24x7 notification_interval 2 notification_period 24x7 notification_options w,u,c,r,f contact_groups admin } define service{ host_name sujith service_description WEB SERVER check_command check_procs!1:!1:!apache2!SNSlSsRl max_check_attempts 1 normal_check_interval 1 retry_check_interval 1 check_period 24x7 notification_interval 2 notification_period 24x7 notification_options w,u,c,r,f contact_groups admin } define service{ host_name sujith service_description DNS check_command check_dig!sujith.elina.in max_check_attempts 1 normal_check_interval 1 retry_check_interval 1 check_period 24x7 notification_interval 2 notification_period 24x7 notification_options w,u,c,r,f contact_groups admin } This is all about the 2 files. And let me give the output also. When I type the command uptime in my router I see like this: sujith@sujith:~$uptime 15:15:50 up 4 days, 4:54, 1 user, load average: 0.76, 0.70, 0.59 And when I see the nagios page for the Host Detail section, the Status Information shows me: 20:17:46 up 3 days, 9:56, 1 user, load average: 0.89, 0.86, 0.71 But the output that I had given you is from the running nagios page. If i would restart nagios then everything will be ok for a while. This is what I want to know why this output comes like this. Again in the /var/nagios/status.dat file is there which when I do ls -lt command , it shows me that its getting updated in each and every minute. Now if u again have any doubt on what I am trying to tell please do mail me. Again I do repeat that when I do /usr/local/nagios/bin/nagios -v /etc/nagios/etc/nagios.cfg It doesn't give me any error. But this misbehaviour is worrying me....

You cannot possibly determine which server is responding using it's uptime output. A more sensible option surely would be it's hostname? #!/bin/bash hostname exit 0 However you're going to run into a lot of trouble trying to use Nagios to monitor a server using its dynamic IP address. I think to start with you need to be looking at a solution such as Dynamic DNS (e.g. No-IP, DynDNS for commercial services, or Bind with DNSSEC/TSIG if you use Bind within your organisation.) Your machines would then change their DNS address when they detect their IP address has changed, and you would definite it's dynamic DNS hostname as the host_name directive to Nagios. Only thing you'd have to watch would be if your DNS service fails, Nagios will fail on everything. Re your last e-mail, please give example outputs of what you see on the command-line and what Nagios says.

The Service Details > are running good as if now. Are you running this command as both a host check and a service check? If so, that's why you're seeing different output. The host check will only run if a service on it goes to a non-OK state, and probably hasn't run for a few days, when the host had only been up for two minutes. It looks like you've defined the same plugin for two checks. If that's the case, they are never going to match. </blockquote> </div> </div> </div> </div><div> <pre><hr size="4" width="90%"> ------------------------------------------------------------------------- Take Surveys.
