Manually modifying monitors

All configured monitors are stored in the monitors table in the database. The various monitor commands manipulate the data that table:

  • monitor:create adds a row
  • monitor:delete deletes a row
  • monitor:enable and monitor:disable change the value of the enabled field
  • monitor:list lists all rows

You can also manually manipulate the table rows instead. Here’s a description of the fields you can manipulate:

  • url: the url to perform uptime and ssl certificate checks on. Take care not to insert duplicate values.
  • uptime_check_enabled: determines if the uptime check should be performed for this monitor.
  • certificate_check_enabled: determines if the ssl certificate check should be performed for this monitor.
  • look_for_string: if this string is not found in the response the uptime check will fail. You may set this to an empty string to disable the check.
  • uptime_check_interval_in_minutes: if the uptime check was successful that site won’t be checked again for at least this number of minutes. When a monitor is created this field is filled with the value of uptime_check_interval_in_minutes in the config file.
  • uptime_check_method: the http method used by the uptime check. If look_for_string is specified when creating the monitor this will be set to get, otherwise this will be head.

All other fields in the monitors table are managed by the package and should not be manually modified.
