====== AIX diagnostic tools ======


==== Data gathering tools ====

=== devscan ===

    The devscan tool facilitates the debugging of storage problems by rapidly gathering a great deal of information about the SAN. It then displays the information in an easy-to-understand manner. You can run devscan from any AIX host, including VIO clients, or from a VIOS.
    
=== pdump ===

    The pdump script extracts information from the running process by using the kdb command, and other AIX tools.
    
=== perfpmr ===

    The perfpmr tool is used extensively by the AIX technical support centers. This package contains a set of tools and instructions for collecting the data needed to analyze performance problems. IBM might ask you to download and use this tool.

=== snap ===

    The snap command is included with the operating system. Snap captures system configuration information for AIX and PowerHA. Product technical support centers regularly request snap output to identify and resolve problems. Snap output can be delivered to IBM in portable archive exchange format (pax).

=== summ ===

    The summ utility is a diagnostic tool used by IBM Support to decode Fibre Channel and SCSI disk AIX error report entries. "summ" generates single-line error messages enhancing the readability of AIX error report and it can aid in diagnosing storage array or SAN fabric-related problems.

=== zsnap ===

    The zsnap utility delivers all the benefits of the standard snap command and captures additional debugging data in an easily understood format. IBM's world-class AIX support centers have teamed up to deliver a more fully integrated tool for data gathering, one that has already been proven to reduce the time needed to resolve customer problems. 

==== Collecting data ====

=== Collecting data ===

    A set of helpful MustGather documents to assist you in gathering testcase information that can be delivered to IBM.

==== Recommendation tools ====

=== VIOS Performance Advisor ===

    The VIOS Advisor application runs on the PowerVM Virtual I/O Server partition. The application collects key performance metrics before analyzing the results. It then provides a health check report listing recommended changes or areas requiring further investigation.

=== FLRT ===

    The Fix Level Recommendation Tool website provides fix recommendations for AIX, PowerHA, VIOS, System Firmware and many key components of your Power Systems server.

=== pstree (rpm) replaced by proctree (bff) ===
