A few weeks ago I wrote about the Performance Data Collectors in IBM i; you can collect many different kinds of performance data, but once you have the data, what is the best way to view and analyze that data? Use the Performance Data Investigator. If you are on 6.1 or 7.1 you already have it.
The Performance Data Investigator was introduced with the 6.1 release and is found in the Navigator for i web console; it is not available in System i Navigator (and it will never be in System i Navigator).
Within the Navigator browser console, you will find the Performance tasks in the left-hand navigation pane. When you select the Performance tasks, you will see the following options:
The Investigate Data option is how you access the Performance Data Investigator. When you take the Investigate Data option, you will see something like the following image:
The initial list of perspectives shows you the set of content packages that are available; a content package is simply a grouping of perspectives for the same type of performance data. The Collection Services content package contains all the graphs and tables for Collection Services data. Which content packages you see depends upon what options of the Performance Tools licensed program product are installed.
You will always see Collection Services and Health Indicators; the capability to view and analyze Collection Services data is part of the base operating system and no other product is necessary.
However, if you want to analyze Disk Watcher or Performance Explorer data, you will need to have the Performance Tools product, Manager feature installed. To analyze Job Watcher data, you need to have the Performance Tools product, Job Watcher feature installed. Below is a screen capture of the Performance Tools product with all the options installed:
On the main Investigate Data panel, open the type of performance data you want to analyze – for example, you can expand the Collection Services folder to show the following navigation:
You can see that the list of perspectives (which is simply a fancy name for a graph or table) is organized by the type of information you want to see. You can further expand the folders to find the perspective you want to view. Once you have identified the view you want to see, you can display it.
Note at the bottom of the screen you have the capability to select which performance data collection you want to display, so you can have various performance data collections in different libraries.
Once you have identified the graph or table you want to display along with the performance collection you want to use, you display the data. An example of what a graph looks like is below:
The Performance Data Investigator has a wealth of capabilities; for a more complete article on the Performance Data Investigator, please refer to the IBM i Performance Data Investigator article on the developerWorks site.
Finally, here is a list of prior blogs with information related to the Performance Data Investigator:

Hi,
I am having an issue with PDI, after clicking on performance on the left tab, nothing appears on the right and eventually I would get a timeout message. I have all the latest i7.1 ptf installed. Any idea how to solve this issue? I am using QSECOFR to signin.

Hi Tan, sorry to hear about that. Without more information, it is hard to tell. I would be glad to hear back on the email I sent asking for some details. Here are a couple things to try: First try logging out and back in or closing your browser and logging in again. Second, there could be something not installed correctly, so make sure all your group PTFs are up to date (HTTP & Database). The third step would be to contact service. They can then gather the details required to provide a full response.
