Diagnostic Tools

SNAplus2 provides several diagnostics tools to help you diagnose and correct problems encountered during SNAplus2 operation:

•Any component detecting a problem or an exception (an abnormal condition that may indicate the cause of a problem) writes an entry to an error log file. In addition, all significant system events can be recorded in an audit log file. You can determine which types of events (problems, exceptions, or audits) are recorded. In a client/server network configuration, you can specify global settings for the types of events to record on all servers, and then override these on individual servers if necessary.

•You can specify the names and directories of the files used to hold error and audit log information; if preferred, you can send both types of information to the same file. On a client/server system, you can send messages from all servers to a central log file on one server (central logging), or send log messages to separate files on each server.

•Log files are generated as text files, and can be viewed using a standard ASCII text editor such as vi.

•You can choose full logging (which includes details of the cause of the log, and any action required, in the log file for each message), or succinct logging (which includes only a summary of the source of the log and the message text). When using succinct logging, you can use the snaphelp command-line utility to obtain the full cause and action text for a particular message number if you need further information.

•For some error conditions, SNAplus2 sends a message to the HP-UX console to warn the operator, in addition to writing a problem message to the error log file.

•Many components can produce a trace file that records the activity of that component. Tracing degrades the performance of SNAplus2 components, and so is normally disabled.
