Logging

Icinga 2 supports three different types of logging:

• File logging (local Icinga 2 log file)
• Syslog facility logging (system's syslog application)
• Console logging (STDOUT on tty)

Note

You can define multiple logging objects at once.

The most common scenario will be logging Icinga 2's output to syslog with severity information.

object SyslogLogger "syslog" {
  severity = "information"
}

For debugging purposes you can install a FileLogger object and forward the debug severity into an Icinga 2 debug file.

object FileLogger "debug-file" {
  severity = "debug",
  path = "/var/log/icinga2/debug.log"
}
