Log file monitoring


Log files can be a valuable source of information. Zabbix provides a way to monitor log files using the Zabbix agent. For that, two special keys are provided:

  • log: Allows us to monitor a single file

  • logrt: Allows us to monitor multiple, rotated files

Both of the log monitoring item keys only work as active items. To see how this functions, let's try out the Zabbix log file monitoring by actually monitoring some files.

Monitoring a single file

Let's start with the simpler case, monitoring a single file. To do so, we could create a couple of test files. To keep things a bit organized, let's create a directory /tmp/zabbix_logmon/ on A test host and create two files in there, logfile1 and logfile2. For both files, use the same content as this:

2016-08-13 13:01:03 a log entry
2016-08-13 13:02:04 second log entry
2016-08-13 13:03:05 third log entry

Tip

Active items must be properly configured for log monitoring to work—we did that in Chapter 3, Monitoring with Zabbix Agents and...
