Alert History - nagios.log file does not display alert date

[fialae]

Nagios Core v 3.2.2
Is there a file that lists the alert history? I select Reports - Alerts - History. From the display i see the file is /usr/local/nagios/var/nagios.log. When I access the log i do see the alerts - but not the date they occured.

How can i get this information? I need a listing of alerts going back 3 months.

Thank you.

The reports menu in core pulls directly from the nagios.log file as you said, but it is parsed before it is dumped to the Web UI, this is where you get the chronological lists/graph from.

Is there a alert history download that lists the alert as well as the date the alert occured?

Additionally, you can run a grep on the archives folder (with wildcard) for "ALERT" to get a full list of alerts.

Code: Select all

root@localhost$  cat /usr/local/nagios/var/archives/* | grep ALERT  >> alerts

How can one get the date to appear next to the alert? Here is an example of what i receive. I need to see the date it occured with it.

[1329144231] SERVICE ALERT: dfw01-is02-006;cpu load maui;WARNING;HARD;4;WARNING - load average: 5.04, 4.67, 5.04

You will need to script a solution, or convert all unix time codes to date/time by hand. You can convert a unix time code string in bash with:

Code: Select all

date -d @[unixtime]
