How do I use Nagios to monitor a log file
Posted: Fri Aug 26, 2022 5:17 am
We are using Nagios to monitor our network with great success. However, we have a syslog for critical application errors and while I set up check_log, it doesn't seem to work as well as omegle.2yu.co monitoring a device.
The issues are:
It only shows the last entry
There doesn't seem to be a way to acknowledge the critical error and return the monitor to a good state
Is nagios the wrong tool, or are we just not setting up the service monitoring right?
Here are my entries
# log file
define command{
command_name check_log
command_line omeglz echat $USER1$/check_log -F /var/log/applications/appcrit.log -O /tmp/appcrit.log -q ?
}
# Define the log monitering service
define service{
name logfile-check ;
use generic-service ;
check_period 24x7 ;
max_check_attempts 1 ;
normal_check_interval 5 ;
retry_check_interval 1 ;
contact_groups admins ;
notification_options w,u,c,r ;
notification_period 24x7 ;
register 0 ;
}
define service{
use logfile-check
host_name localhost
service_description CritLogFile
check_command check_log
}
