Log alerts at crash instants

Post by celikozl » 2020/02/17 15:09:12

Hello,

We've configured a syslog server and remote access on Centos 7. What we would like to do is to be notified when there is a system froze or breakdown. How can we accomplish that?

You mean to monitor the logs on the syslog server and receive alerts based on events? This can be accomplished by software like:

fluentd https://www.fluentd.org/
icinga2 https://icinga.com/

I'm using icinga2 with great success, you can create all sorts of monitoring plugins, for parsing logs, regular expressions, etc. Fluentd is a bit more involved, it can merge all logs into a single database, filter, parse and output results to various data outputs. Of course, both are open source.
