Example Program Containing Error Information
Example Program Containing Error
Information
Given a vendor_code, the following example creates a log filter file
(/tmp/input_file) that the troubleshooting tool osidump uses to check for
errors (via log instances in the log file). The file created records a time
period (during which the error is assumed to have occurred), the log class
to filter on, and the log instance. Following the program is sample
output.
/* This routine creates a input FORMAT file for use by the “osidump”
* command. The FORMAT file is created with two time lines, time_from
* and time_to. A log class of ERROR is used to search on, and if a
* log instance is present (upper 16 bits of the vendor code), then
* the instance will also be added to the filter file.
