Critical Fatal errors that may stop the system. Error
Error Errors that crucially affect the system. This type of error can be avoided by using
failover or other countermeasures.
Error
Warning Errors that enable the system to continue but, if left, might cause the system to
operate improperly.
Warning
Information Information that indicates the operating history when the system operates
normally.
Information
Error information is filtered according to the error level, and then collected.
The error information in error logs and in the event log is collected based on a user-defined
collection level. The collection levels are as follows:
Collection levels for error logs and event logs: The event log always collects error
information at the Error level or higher.
The error log can use any of the following logging levels to collect error information:
– Collects no error information.
– Collects error information at the Error level and higher.
– Collects error information at the Warning level and higher.
– Collects error information at the Information level and higher (that is, all levels).
– Collects error information at the Information level and higher (including
maintenance information).
Collection levels for log information in trace files:
– Outputs no trace information.
– Outputs error information only.
– Outputs trace information on program operation summaries.
– Outputs trace information on program operation details.
– Outputs all trace information.
For details on how to set the collection level, see section 3.5.2.
