Update Assessment landing page in Pega Predictive Diagnostic Cloud

Suggest edit Updated on January 19, 2022

The Update Assessment landing page highlights differences in cases frequency in a monitored system after recent Pega Platform™ updates. You can use the page to assess the impact that the updates have on your system and to correlate changes in cases that Pega Predictive Diagnostic Cloud™ (PDC) creates with specific update packages.

The Update Assessment landing page shows the impact of updates on your application from the last 12 days. The Update to assess drop-down list displays packages that you imported into your system either manually or through the Deployment Manager, sorted from newest to oldest. The name of the update consists of the date and time of the update and the name of the package imported to Pega Platform.

Tip: You can find a more comprehensive list of updates in the Platform Imports section on the Changes Summary landing page. For more information, see the Changes Summary landing page in PDC.

You can select a specific update to see the detailed metrics. The following figure shows the Update Assessment landing page displaying information for a selected update:

Update Assessment highlights cases that illustrate ongoing or potential stability issues in your system. For each package, you can see new cases, cases that increased in frequency, and cases that decreased in frequency. You can analyze the changes using the following views:

  • New issues to see which cases in your system appeared first after the selected update. You can check when they first appeared, when they were last seen, and how many events were detected.
  • Less frequent to see which cases in your system appear less frequently after the selected update. You can check when they first appeared, when they were last seen, and the percentage of decrease in frequency for each case.
  • More frequent to see which cases in your system appear more frequently after the selected update. You can check when they first appeared, when they were last seen, and the percentage of increase in frequency for each case.

You can expand each case for additional insight. The following figure shows the information that PDC presents when you expand a case. The chart shows the change in frequency of events connected to the selected case across all updates from the last 14 days. The numbers correspond to each update visible in the Update to assess drop-down list.

Interpreting the Update Assessment data

You can use Update Assessment as a quality control tool for every Pega Platform application that you develop. PDC highlights the most important new issues with the NEEDS REVIEW tag. You should always analyze those issues first and immediately resolve any impactful exceptions. An increase in case frequency might be related to increased user traffic and does not always signify an issue, but you should analyze the increase to exclude a possible problem.

You should compare differences in case frequency after every import to accurately assess whether the update introduced or solved any issues. Although not every issue is equally important, as a best practice, you should address less significant issues after each update so that they do not overshadow the more important problems.

For more information on changes in your system after Pega Platform updates, see the Changes Summary landing page in PDC.
