Hi hi, Disclaimer: "Not a linux guy, so I don't know the paths" You should be able to run (test really), the check commands from the install dir: root @ paranoid: cd /usr/local/nagios/libexec root @ paranoid: ./check_users -w 3 -c 10 USERS WARNING - 4 users currently logged in |users=4;3;10;0 root @ paranoid: ./check_by_ssh -H ironman -C "/usr/local/nagios/libexec/check_users -w 3 -c 10" USERS OK - 0 users currently logged in |users=0;3;10;0 Nagios does not need to be running to perform those commands successfully. If Nagios is already running, you need the correct definitions in your commands.cfg file (/usr/local/nagios/etc on Sun) as well as your localhost.cfg + whatever *.cfg you are using for remote checks. Lastly, you only need to start Nagios once via /etc/init.d/nagios stop|start|restart ... its not part of the command line execution templates or syntax. I hope my reply was clear enough to get you onto the right path. -Marc <div>On 3/20/07, Di Giambelardini Gabriele <<a href="mailto:g.digiambelardini-hYieKUmLjM+onA0d6jMUrA@public.gmane.org"> g.digiambelardini-hYieKUmLjM+onA0d6jMUrA@public.gmane.org</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">hi to all, i have nagios 2.8 installed on an redhat es 4. the problem is: some check work fine, only if i start nagios after login my server and i type /etc/init.d/nagios start/stop/restart. instead if i type che command service nagios start/stop/restart these check don't go... a the same time if nagios start at the boot when i reboot my server. some body can help me??? ------------------------------------------------------------------------- Take Surveys.
