With this value, all goes OK. When I put a timeout in check_icmp of 40s, I receive this message Warning: The check of host 'teste' looks like it was orphaned (results never came back). I'm scheduling an immediate check of the host... And nagios will ignore the max_attempts value.

So this is hard to trace, but once I have more than 100 hosts I monitor with this configuration, the problem occurs at least once a day (we don't have many down hosts per day). With lab tests, nagios usually runs as expected, and I don't understand why (murphy's law?). :) Regards, <div class="moz-signature"> <meta http-equiv="Content-Type" content="text/html; "> <title>Emanuel Massano</title> Emanuel Massano FCCN Av. do Brasil, n.º 101 1700-066 Lisboa Tel: +351 21 844 0100 Fax: +351 21 847 2167 E-Mail: <a moz-do-not-send="true" href="mailto:emanuel.massano@fccn.pt">emanuel.massano@fccn.pt </a><a moz-do-not-send="true" href="http://www.fccn.pt/" title="http://www.fccn.pt">www.fccn.pt</a> Aviso de Confidencialidade Esta mensagem é exclusivamente destinada ao seu destinatário, podendo conter informação CONFIDENCIAL, cuja divulgação está expressamente vedada nos termos da lei.

To show only the configuration that's important for this case, here are the configurations for the type of hosts that I monitor this way First, the host define host { name WAN-Instituicao check_command check_instituicao max_check_attempts 10 check_interval 0 check_period 24x7 obsess_over_host 0 active_checks_enabled 1 notification_interval 10 notification_period 24x7 notifications_enabled 1 register 0 notification_options d,r hostgroups WAN contact_groups admins,prevencao } define host { use WAN-Instituicao host_name test alias test.fccn.pt address x.x.x.x (not shown) parents gw-fw01-Outside check_command check_instituicao hostgroups WAN contact_groups admins,prevencao } Then, the only service I have for this kind of hosts: define service { name ping-wan-instituicoes use _template-base check_command check_ping_ip4!1000.0,100%!2000.0,100%!5 max_check_attempts 8 normal_check_interval 5 retry_check_interval 1 active_checks_enabled 1 check_period 24x7 notification_interval 10 notification_period 24x7 notifications_enabled 1 register 0 notification_options c,r servicegroups rcts contact_groups admins,prevencao } define service { use ping-wan-instituicoes service_description ping host_name test servicegroups rcts contact_groups admins,prevencao } And finally, the commands: define command{ command_name check_instituicao command_line $USER1$/check_icmp -H $HOSTADDRESS$ -w 2s,80% -c 9s,100% -n 20 -i 1.5s -t 40s -l 0 } define command{ command_name check_ping_ip4 command_line $USER1$/check_icmp -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -n $ARG3$ } If you would like to see other configuration files, I can send them.
