VRF support for syslog

An overview of VRF support for syslog and example commands.

You can configure syslog on any routing instance. If a routing instance is not specified for logging, the default routing instance is used to access the remote host. You can also configure a facility override value that replaces the facility fields in all log entries that are sent to a remote host. For example, you can specify multiple facility values for a set of log entries that are sent by the vRouter to a log remote host. Before sending the entries to the remote host, the facility values are replaced with the override value.

The following examples show syslog configurations that use these values:

  • Routing instance = BLUE
  • IP address of the host = 10.10.10.10
  • Facility value = auth (Authentication and authorization)
  • Level = crit (Critical)

The following example shows how to configure syslog for the default routing instance.

vyatta@R1# set system syslog host 10.10.10.10 facility auth level crit
vyatta@R1# commit
vyatta@R1# run show configuration
system {
        syslog {
                host 10.10.10.10 {
                        facility auth {
                                level crit
                        }
                }
        }
}

The following example shows the same configuration sequence for the BLUE routing instance.

vyatta@R1# set routing routing-instance BLUE system syslog host 10.10.10.10 facility auth level crit
vyatta@R1# commit
vyatta@R1# run show configuration
routing {
        routing-instance BLUE {
                system {
                        syslog {
                                host 10.10.10.10 {
                                        facility auth {
                                           level crit
                                        }
                                }
                        }
                }
        }
}
