Re: iDoctor

I would like to add, that while iDoctor is indeed a powerful tool, there is also the Performance Data Investigator (PDI) that comes with the operating system.
PDI is a graphical interface over the IBM i performance data and has a rich set of charts for Collection Services included with the base OS (no additional products are needed).
I.e., it’s FREE.

In fact, many of the charts in PDI are the exact same ones you get with iDoctor (but iDoctor does have many additional features, mostly needed for deep performance diagnostics).

If you have the 5770-PT1 product, you also have charts available for Disk Watcher data, PEX profile collections, and Database charts.
With the 5770-PT1 Job Watcher feature, you also have charts for Job Watcher data.

While iDoctor does have more features, it is more difficult to use (imo). PDI is a formal IBM product; iDoctor is a service offering.

If you are interested in learning more about PDI, feel free to contact me offline.

sounds very interesting... yes just produced reports (splf's) for *profile,
*stats, *trace and they all lend nothing of real value from a "text report"
standpoint... unless you know EXACTLY what you are looking for.

but this is good to explore and understand the inner workings of what
iDoctor will be using

You certainly can do that, and I do frequently, however when I have access
to iDoctor I'll use it in a heartbeat since it makes the tasks that much
easier. Then there are the pretty graphs it makes. When we present data
to
the execs saying ya, you need to spend some money, those graphs usually do
the job for me.

Sometimes the thing you are looking for is something that's not there. You
expect 1 million I/O and you only see 300,000. Hmmm, that's a pause point.
The graphs help you see things of that nature more easily.

Have fun which ever you choose, performance investigation is the best part
of my job since it's fun to find and correct an issue.

thanks jim - just did a bit of research myself and why not start with PEX
and utilize iDoctor only if you have to for the *trace data?

I'll start with PEX and proceed towards the possibility of iDoctor

Thanks

After spending some time to learn what it can do, it's worth many
times what you pay for it.

It makes getting through the performance data significantly easier.
You are able to find performance problems you otherwise would need
keen insight in to the performance files for.

When you need a PEX trace, it analyzes it for you.

Last question: What do you think our friends in Rochester use when
you send performance data to them?

Has anyone any experience or testimonials regarding iDoctor?

I know it comes with a price and wondering its value and if there are
any similar products also worth investigating?
