I'm using Nagios 1.2 and the situation is: Sometimes Nagios receives the passive check but it does nothing with it, as the following example from nagios.log : "om nagios: EXTERNAL COMMAND: PROCESS_SERVICE_CHECK_RESULT;om;BILLING;0;BILLING stopped" And Sometimes it does what it should do, as the following example from nagios.log : "om nagios: EXTERNAL COMMAND: PROCESS_SERVICE_CHECK_RESULT;om;BILLING;0;BILLING stopped" "om nagios: SERVICE ALERT: om;BILLING;OK;HARD;1;BILLING stopped" "om nagios: SERVICE EVENT HANDLER: om;BILLING;OK;HARD;1;myhandler" The configurations for this service is that one: "define service{ use generic-service ; Name of service template to use host_name om service_description BILLING active_checks_enabled 0 check_period none check_command check_dummy!0 } " And the general configuration for the services is this one: "define service{ name generic-service ; The 'name' of this service template active_checks_enabled 1 ; Active service checks are enabled passive_checks_enabled 1 ; Passive service checks are enabled/accepted parallelize_check 1 ; Active service checks should be parallelized (disabling this can lead to major performance problems) obsess_over_service 1 ; We should obsess over this service (if necessary) check_freshness 0 ; Default is to NOT check service 'freshness' notifications_enabled 0 ; Service notifications are disabled notification_options w,u,c,r notification_interval 0 notification_period 24x7 event_handler_enabled 1 ; Service event handler is enabled event_handler myhandler flap_detection_enabled 1 ; Flap detection is enabled failure_prediction_enabled 1 ; Failure prediction is enabled process_perf_data 1 ; Process performance data retain_status_information 1 ; Retain status information across program restarts retain_nonstatus_information 1 ; Retain non-status information across program restarts normal_check_interval 1 retry_check_interval 1 max_check_attempts 1 check_period 24x7 contact_groups admins register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL SERVICE, JUST A TEMPLATE! } " Other relevant configuration from nagios.cfg: check_external_commands=1 command_check_interval=-1 accept_passive_service_checks=1 Does anyone know how to solve this problem?
