Service Status

A status for every purpose

There are 7 statuses in total. These can be distinguished by their name and color:

OK
INFO
NOTICE
WARNING
ALERT
CRITICAL
UNKNOWN

The numerical value (exit code) of each status is

  • OK = 0
  • INFO = 0
  • NOTICE = 1
  • WARNING = 2
  • ALERT = 3
  • CRITICAL = 4
  • UNKNOWN = 5

Each status has a special meaning, which we would like to explain below.

OK

This status is set when the service is healthy.

INFO

The status INFO is a special status and is set when a service has been newly set up or when the monitoring of the service is suspended for a planned reason, e.g. when maintenance work is carried out. While the service is in the status INFO, no notifications are sent.

NOTICE
WARNING
ALERT
CRITICAL

Status NOTICE to CRITICAL is used when setting thresholds of services.

The recommended use of each status is:

  • NOTICE: the service does not require any attention at first
  • WARNING: the service should be checked
  • ALERT: the service should be urgently checked
  • CRITICAL: the service is down or does not respond within a certain time

Status CRITICAL plays a special role in reports, since only this status is included in the calculation of the percentage availability of services.

UNKNOWN

Like status INFO, status UNKNOWN is a special status that is set when an error occurred during the execution of the service checks.
