# The following Fluentd parser plugin, aims to simplify the parsing of multiline
|
|
# logs found in Kubernetes nodes. Since many log files shared the same format and
|
|
# in order to simplify the configuration, this plugin provides a 'kubernetes' format
|
|
# parser (built on top of MultilineParser).
|
|
#
|
|
# When tailing files, this 'kubernetes' format should be applied to the following
|
|
# log file sources:
|
|
#
|
|
# - /var/log/kubelet.log
|
|
# - /var/log/kube-proxy.log
|
|
# - /var/log/kube-apiserver.log
|
|
# - /var/log/kube-controller-manager.log
|
|
# - /var/log/kube-scheduler.log
|
|
# - /var/log/rescheduler.log
|
|
# - /var/log/glbc.log
|
|
# - /var/log/cluster-autoscaler.log
|
|
#
|
|
# Usage:
|
|
#
|
|
# ---- fluentd.conf ----
|
|
#
|
|
# <source>
|
|
# @type tail
|
|
# path ./kubelet.log
|
|
# read_from_head yes
|
|
# tag kubelet
|
|
# <parse>
|
|
# @type kubernetes
|
|
# </parse>
|
