I've used Nagios for a few years, but my new installation is really racking my brain. I was testing with my first host and first service, but they are never checked or scheduled to be checked. I want both active and passive checks, because I'm experimenting with my own distributed monitoring system (which is a first for me). I'm including the important parts of my config files. # cat /etc/nagios/nagios.cfg # Written by NagiosMainExporter from Lilac Configurator 1.0.3 on February 7, 2010, 3:19 pm log_file=/var/log/nagios/nagios.log temp_file=/var/nagios/nagios.tmp status_file=/var/nagios/status.dat status_update_interval=10 nagios_user=nagios nagios_group=nagios enable_notifications=1 execute_service_checks=1 accept_passive_service_checks=1 enable_event_handlers=1 log_rotation_method=d log_archive_path=/var/log/nagios/archives check_external_commands=1 command_check_interval=-1 command_file=/var/nagios/rw/nagios.cmd lock_file=/var/run/nagios.pid retain_state_information=1 state_retention_file=/var/nagios/retention.dat retention_update_interval=60 use_retained_program_state=1 use_syslog=1 log_notifications=1 log_service_retries=1 log_host_retries=1 log_event_handlers=1 log_initial_states=0 log_external_commands=1 log_passive_checks=1 external_command_buffer_slots=4096 sleep_time=0.25 service_interleave_factor=s max_concurrent_checks=0 service_reaper_frequency=10 interval_length=60 use_aggressive_host_checking=1 enable_flap_detection=1 low_service_flap_threshold=5 high_service_flap_threshold=20 low_host_flap_threshold=5 high_host_flap_threshold=20 soft_state_dependencies=0 service_check_timeout=60 host_check_timeout=30 event_handler_timeout=30 notification_timeout=30 ocsp_timeout=5 perfdata_timeout=5 obsess_over_services=1 process_performance_data=0 check_for_orphaned_services=1 check_service_freshness=1 date_format=us illegal_object_name_chars=()= illegal_macro_output_chars=`~$&|' admin_email=<a href="mailto:admin@dougware.net">admin@dougware.net</a> admin_pager=pagenagios@localhost execute_host_checks=1 service_inter_check_delay_method=s use_retained_scheduling_info=1 accept_passive_host_checks=1 max_service_check_spread=30 host_inter_check_delay_method=s max_host_check_spread=30 auto_reschedule_checks=1 auto_rescheduling_interval=30 auto_rescheduling_window=180 obsess_over_hosts=1 check_host_freshness=1 host_freshness_check_interval=60 service_freshness_check_interval=60 use_regexp_matching=0 use_true_regexp_matching=0 event_broker_options=-1 daemon_dumps_core=0 object_cache_file=/var/nagios/objects.cache precached_object_file=/var/nagios/objects.precache retained_host_attribute_mask=0 retained_service_attribute_mask=0 retained_process_host_attribute_mask=0 retained_process_service_attribute_mask=0 retained_contact_host_attribute_mask=0 retained_contact_service_attribute_mask=0 check_result_reaper_frequency=2 max_check_result_reaper_time=30 check_result_path=/var/nagios/spool/checkresults max_check_result_file_age=3600 translate_passive_host_checks=1 passive_host_checks_are_soft=1 enable_predictive_host_dependency_checks=1 enable_predictive_service_dependency_checks=1 cached_host_check_horizon=15 cached_service_check_horizon=15 use_large_installation_tweaks=1 enable_environment_macros=1 additional_freshness_latency=15 enable_embedded_perl=1 use_embedded_perl_implicitly=1 p1_file=/usr/bin/<a href="http://p1.pl">p1.pl</a> debug_file=/var/log/nagios/nagios.debug debug_level=0 debug_verbosity=1 max_debug_file_size=1000000 resource_file=/etc/nagios/resource.cfg cfg_dir=/etc/nagios/objects cat /etc/nagios/objects/services.cfg # Written by NagiosServiceExporter from Lilac Configurator 1.0.3 on February 7, 2010, 3:19 pm define service { host_name Server1 service_description SSH initial_state o check_command check_ssh max_check_attempts 3 normal_check_interval 2 retry_interval 1 first_notification_delay 5 active_checks_enabled 1 passive_checks_enabled 1 check_period 24x7 parallelize_check 1 obsess_over_service 1 check_freshness 1 freshness_threshold 120 notification_interval 15 notification_period 24x7 notifications_enabled 1 display_name SSH notification_options w,c,r,s } cat /etc/nagios/objects/hosts.cfg # Written by NagiosHostExporter from Lilac Configurator 1.0.3 on February 7, 2010, 3:19 pm define host { host_name Server1 initial_state o check_command check_ping retry_interval 1 first_notification_delay 15 max_check_attempts 3 check_interval 2 passive_checks_enabled 1 check_period 24x7 obsess_over_host 1 check_freshness 1 freshness_threshold 120 active_checks_enabled 1 event_handler_enabled 0 notification_interval 15 notification_period 24x7 notifications_enabled 1 failure_prediction_enabled 0 alias <a href="http://server1.dougware.net">server1.dougware.net</a> display_name Server1 address <a href="http://server1.dougware.net">server1.dougware.net</a> notification_options d,u,r,s contact_groups DougWare hostgroups DougWare } I'm sure that I have a really simple issue, but I just can't put my finger on it.
