With this check you can monitor the number of failures across all indices of a
Graylog instance. It outputs the total number of failures and the number of
failures in a given timeframe (default: last 30m). Also the number of affected
indices of the last failures are shown. The long output shows detailed
information of the last 30 failures.
Needs the datasource "Check state of Graylog" to be configured.
One service is created.
