| Hi. I'm not exactly an expert on the subject, but this excerpt from
the Web pretty much summarizes key differences for Perf Advisor on UNIX
and OpenVMS -- that is, analysis and recommendations:
POLYCENTER Performance Advisor for Digital UNIX analyzes data through
the application of expert system technology. It identifies specific
performance problems, presents detailed supporting evidence, and makes
recommendations to improve Digital UNIX system performance.
STATUS - POLYCENTER Performance Advisor V3.1 Supported on: DIGITAL UNIX
V3.0-3.2D, 4.0 Status: In Beta now; release planned for March 1997
POLYCENTER Performance Advisor for OpenVMS (formerly known as
DECperformance Solution, or DECps) analyzes data through the
application of expert system technology. It identifies specific
performance problems, presents detailed supporting evidence, and makes
recommendations to improve OpenVMS system and VMScluster performance.
STATUS - POLYCENTER Performance Advisor V2.3 Supported on: OpenVMS VAX
V5.5-2, 6.0, 6.1, 6.2, 7.0 OpenVMS Alpha V6.1-6.2, 7.0 Status: In Beta
now; release planned for March 1997
Now, Serverworks collects data, and can set threshold alarms on CPU,
File system utilization, temperature, and network activity. It's more
of an operational, "ooops, there's something going haywire, tell me
abut it!". Polycenter Perf Advisor & DC on the other hand is a much
more cerebral approach (for which you'll pay $$ to Computer Associates,
believe me) that uses expert system technology to gather data and
analyze the results, AND give you specific recommendations on how
to fix the problem(s).
Does that help?
Suggest you also go to the WEB IR web page, select SPDs, and enter
SP4697 in the search box. It will bring up the UNIX Perf Advisor
SPD for you. Then check out the Serverworks Whitepaper (nicely
redone) at
http://www.digital.com/info/alphaserver/sworks/sworkswp.html.
This will help you position for the customer.
And remember, Serverworks does a decent job of reporting, but when you
want a performance "doctor", you gets what you pays for.
