This article will explain in detail how to achieve the trigger interval in nagios. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Go back to the important alarm section and mention it again:

The default detection time for nagios3.4.1 is every 5 minutes.

Check_interval 5 detection time

Retry_interval 1 retry interval

It was changed in the templates.cfg file.

2. The default time for sending email is 30 seconds. There is a parameter called notification_timeout=30 in nagios.conf.

3.

You can define the parameter normal_check_interval in define service, which overrides the default definition in the service inheritance template.

3min check once and write: define service {... Normal_check_interval 3... }

Only one of these four states can send an alarm message, and those that are not needed can be removed.

Maximum number of retries for max_,. That is, the number of times to retry the check when a fault is found. When the set value is still abnormal, an alarm is issued.

The interval between normal_check_, checks. That is, how often do you check?

The interval between retry_, retries and max_ can be understood.

4. Change the interval of information frequency.

Vim nagios.cfg

Insert a sentence

Cfg_file=/usr/local/nagios/etc/objects/escalations.cfg

Vim / usr/local/nagios/etc/objects/escalations.cfg

Add the following

Define hostescalation {

Host_name 192.168.10.21 # monitored host name, consistent with hosts.cfg, with multiple hosts separated by commas

First_notification 5 # Article 5 message, change the frequency interval

Last_notification 0 # Article n message, recovery frequency interval

Notification_interval 600 # Notification interval (10 hours)

Contact_groups mygroup

}

Note: from the 5th tone warning all servers recover before the warning is sent to mygroup. The time is 10 hours.

Define serviceescalation {

Host_name 192.168.10.21 # monitored host name, consistent with Hosts.cfg

Service_description check_http,check_uptime # monitored service name, which is the same as in services.cfg

First_notification 5

Last_notification 0

Notification_interval 600

Contact_groups mygroup

}

Add completion test whether the configuration file is correct

/ usr/local/nagios/bin/nagios-v / usr/local/nagios/etc/nagios.cfg

If there is no problem with the test, just restart the nagios service and OK.

Service nagios restart
