2.11.2 Filtering of error information

Errors that HDLM detects are classified into error levels. Table 2-8 Error levels lists the error levels, in order of adverse effect on the system.

Table 2-8 Error levels

Error level	Meaning	Level shown in Event Viewer
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 3.7.2 Setting the HDLM functionality by using the Options window and the set operation.
