2.3 Nagios Configuring message Alarms

Currently Nagios can only view the state of each machine's services on a browser, and when a machine goes down or a service goes down, we don't know because we can't stare at the service at all times. At this point, you need to use the alarm system, let it automation, when the problem is found in time to notify us. The following configuration uses e-mail to implement the alarm.

operate on the service side!

The message recipient is defined first.

[[email protected] ~]# vim /etc/nagios/objects/contacts.cfgdefine contact{         contact_name                     test1         use                              generic-contact         alias                            email1         email                            [ Email protected]}define contact{        contact_name                     test2         use                               generic-contact        alias                             email2        email                             [email protected]}define contactgroup{         contactgroup_name               common         alias                            common         members                          TEST1,TEST2}

Description: Contact.cfg can define either user or group, define two user test1 and Test2, and then add the two user to the common group. e-mail will be sent to the common group, then [email protected] and [email protected] will receive mail.

Then add Contactgroup to the service that needs to be alerted.

[Email protected] ~]# vim/etc/nagios/conf.d/192.168.56.128.cfg

Increased alarm configuration for check_load services

define service{   use             generic-service   host_name       192.168.56.128   service_description  check_load   check_ Command    check_nrpe!check_load   max_check_attempts   5    normal_check_interval   1   contact_groups    common   notifications_enabled  1   notification_period    24X7   NOTIFICATION_OPTIONS  W,U,C,R} 

Description: notifications_enabled 1 Indicates whether the alert function is turned on. 1 is on, 0 is disabled. In general, this option is defined in the main configuration file (Nagios.cfg), with the same effect. Notification_period 24x7 Indicates the time period when reminders are sent. If you are not within the defined time period, no reminders will be sent for any issues. Notification_options:w,u,c,r represents the status of the service. W is warning,u for unknown,c and critical,r for recovery. Similarly, there is a status of host: D,u,r,f,n. The D status indicates that the down,u for the Unreachable,r state reverts to ok,f for Flapping,n to not send reminders. Need to be added to the host's defined configuration to take effect.

After editing the configuration file, restart the Nagios service
