HAProxy monitoring with Netdata

Monitors frontend and backend metrics such as bytes in, bytes out, sessions current, sessions in queue current. And health metrics such as backend servers status (server check should be used).

Plugin can obtain data from url OR unix socket.

Requirement: Socket MUST be readable AND writable by the netdata user.

It produces:

  1. Frontend family charts

    • Kilobytes in/s
    • Kilobytes out/s
    • Sessions current
    • Sessions in queue current

  2. Backend family charts

    • Kilobytes in/s
    • Kilobytes out/s
    • Sessions current
    • Sessions in queue current

  3. Health chart

    • number of failed servers for every backend (in DOWN state)

Configuration

Edit the python.d/haproxy.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/haproxy.conf

Sample:

via_url:
  user       : 'username' # ONLY IF stats auth is used
  pass       : 'password' # # ONLY IF stats auth is used
  url     : 'http://ip.address:port/url;csv;norefresh'

OR

via_socket:
  socket       : 'path/to/haproxy/sock'

If no configuration is given, module will fail to run.
