Dezember 2005 08:56 An: nagios-users@lists.sourceforge.net Betreff: [Nagios-users] not able to get the status of some services from the remote machine even with net-snmp running </DIV>hey friends, I am not an expert in Nagios.I have configured Nagios to monitor few hosts in my Network. There is one FC3 server on which few services like (mysql,dns,apache,postfix) etc are running on that server.But through nagios I am not able to get the information about the disk & swap status from the remote machine even though snmp & snmptrapd services are running on this server. services.cfg define service{ host_name mail service_description swapspacechecking check_command check_swap max_check_attempts 5 normal_check_interval 5 retry_check_interval 3 check_period nonworkhours notification_interval 30 notification_period nonworkhours notification_options w,c,r contact_groups linux-admins } define service{ host_name mail service_description disk_checking_mail check_command check_local_disk_mail max_check_attempts 5 normal_check_interval 5 retry_check_interval 3 check_period nonworkhours notification_interval 30 notification_period nonworkhours notification_options w,c,r contact_groups linux-admins } checkcommands.cfg file define command{ command_name check_local_disk_mail command_line $USER1$/check_disk -w 10% -c 5% -p /var -p /usr -p /home -p / -p /opt } define command{ command_name check_swap command_line $USER1$/check_swap -w 35% -c 15% } In both the above cases the nagios is showing the status for the local machine on which the nagios is running not for the remote machine. But plugins for apache ,local load ,mysql on mail machine are working fine. Does local_disk and check_swap plugins requires some special configuration. Moreover I would like to monitor postfix(mailq) running on the machine.What I have to do to the get status of mailq ? The name of the machine which I am monitoring is mail and the machine name on which nagios is running is cluster1. Please guide me. Thanks & Regards Ankush Grover </BLOCKQUOTE></BODY></HTML>
