Log Query (CSUALGQ)
Use the Log Query verb to retrieve system log (SYSLOG) message data and CCA log message data from the coprocessor. Syslog data is available for one of the five latest boot cycles (current boot cycle and up to four previous boot cycles). CCA log message data is optionally available during the current boot cycle. The verb supports service personnel and developers in testing and debugging issues.
The SYSLOG for a boot cycle is initially populated with operating system messages and other startup messages, but more messages are written as CCA encounters errors at log level 12 or above. A log level of 12 means, that if an error at return code value 12 or higher occurs during the processing of an operation or during general system processing, then a descriptive message is sent to the SYSLOG. The log level is configurable, with a default value of 12. If configured to be logged, messages for return code 4 and return code 8 are saved in volatile memory (CCA log) separately from messages in the SYSLOG. This keeps these messages from overwhelming more important errors and system messages. Each new boot cycle wipes out any previous CCA log, while the current SYSLOG and up to four previous boot cycle SYSLOGs are maintained. The CCA log is a circular log. When the log is full, the oldest messages are replaced as needed with any new messages.
