httpcheck

Module monitors remote http server for availability and response time.

Following charts are drawn per job:

  1. Response time ms
  • Time in 0.1 ms resolution in which the server responds. If the connection failed, the value is missing.
  1. Status boolean
  • Connection successful
  • Unexpected content: No Regex match found in the response
  • Unexpected status code: Do we get 500 errors?
  • Connection failed: port not listening or blocked
  • Connection timed out: host or port unreachable

configuration

Sample configuration and their default values.

server:
  url: 'http://host:port/path'  # required
  status_accepted:              # optional
    - 200
  timeout: 1                    # optional, supports decimals (e.g. 0.2)
  update_every: 3               # optional
  regex: 'REGULAR_EXPRESSION'   # optional, see https://docs.python.org/3/howto/regex.html
  redirect: yes                 # optional

notes

  • The status chart is primarily intended for alarms, badges or for access via API.
  • A system/service/firewall might block Netdata's access if a portscan or similar is detected.
  • This plugin is meant for simple use cases. Currently, the accuracy of the response time is low and should be used as reference only.
