fluent-plugin-ping-message

Fluentd plugins:

  • to generate ping messages for monitoring of heatbeats
  • to check ping messages not arrived, and emits notifications

Configuration

PingMessageInput

To generate 1 ping message per 60seconds(default):

<source>
  @type ping_message
</source>
#=> tag: 'ping'
#   message: {'data' => 'your.hostname.local'}

Change ping message interval into 30 seconds, and fix tag and data:

<source>
  @type ping_message
  tag ping.webserver
  interval 30
  data ping message from ${hostname}
</source>
#=> tag: 'ping.webserver'
#   message: {'data' => 'ping message from your.hostname.local'}

PingMessageCheckerOutput

To receive ping messages and checks ping message in-arrival, use @type ping_message_checker:

<match ping.**>
  @type ping_message_checker
  tag missing.ping
  check_interval  3600   # 1hour by default
  notification_times 3   # 3 times by default
</match>

With this configuration, this plugin save the list of ping messages' data field values. And then, at the time of ping message missing, notification message emitted with the specified tag and record like {"data": "failing.hostname.local"}.
