    Summary of Performance Analytic Indicators to Measure Application Performance

    Performance Analytic (PA) indicators provide valuable insights into the performance of business applications by tracking incidents, problems, changes, and closed change requests. This helps organizations enhance application performance through informed decision-making. Application Portfolio Management (APM) utilizes these indicators sourced from Performance Analytics (PA).

    Key Features

    • Scheduled PA jobs must be run in a specific order for accurate performance evaluation:
      • [PA Incident] Daily Data Collection
      • [PA Change] Daily Data Collection
      • [PA Problem] Daily Data Collection
      • [APM Scheduled job] Load Application Indicators and compute Application Scores
    • For historic data retrieval (older than six months), the Performance Analytics Premium for APM plugin is required.
    • Scores are generated based on the scheduled job runs, with specific frequencies for monthly, quarterly, and yearly data collections.
    • APM frequency for collecting data must be equal to or greater than the data source indicator frequency.

    Key Outcomes

    By effectively utilizing PA indicators, APM customers can:

    • Monitor application performance through incident and change metrics.
    • Regenerate APM scores to ensure they reflect current data, deleting previous scores as needed.
    • Adjust system properties to accommodate a larger number of business applications for comprehensive performance breakdowns.

    This ensures that APM customers can make data-driven decisions to optimize their application portfolio effectively.

    Use performance analytic (PA) indicators to know the count of incidents, problems, and changes logged against a business application and use this insight to improve the performance of your applications.

    Application Portfolio Management uses indicators that are sourced from Performance Analytics (PA). These indicators give a count of incidents, problems, changes, and the number of change requests that were closed on a given day. Follow the given order to run the PA jobs at the scheduled time, and get the scores of the indicators to evaluate the performance of your business applications.

    Order in which to run PA jobs and generate scores

    You should run the scheduled jobs in the following order:

    1. [PA Incident] Daily Data Collection.
    2. [PA Change] Daily Data Collection.
    3. [PA Problem] Daily Data Collection.
    4. [APM Scheduled job] Load Application Indicators and compute Application Scores.

    If there are historic data, then run them in the following order:

    Note:

    You require Performance Analytics Premium for APM (com.snc.pa.premium.apm) plugin to retrieve historic data that are older than six months.

    1. [PA Incident] Historic Data Collection.
    2. [PA Change] Historic Data Collection.
    3. [PA Problem] Historic Data Collection.
    4. Regenerate APM scores for required time period. This action deletes the existing scores including daily scores and generates new scores instead of just updating the existing scores.

    Frequency at which indicator scores are generated

    Scores are generated as per the scheduled run of the job that executes the script. If the indicator frequency is:

    Monthly
    scores are generated only on the last day of a month.
    Quarter
    scores are generated only on the last day of a quarter.
    Yearly
    scores are generated only on the last day of a year.
    Note:
    Fiscal periods should be generated in the same time zone in which the scores are generated.

    Collection of PA indicator score data

    The period unit (days, weeks, or month) at which the PA indicator scores are collected and preserved depends on the frequency of the data source indicator. However, the frequency at which the application indicator collects the PA indicator data source scores varies.

    In APM, the frequency of the application indicator must be greater than or equal to the frequency of the data source indicator.

    The following table describes the frequency at which APM collects data from the data source indicators after the job runs:

    Table 1. APM data collection frequency
    APM frequency Data source indicator frequency
    Monthly Monthly
    Quarterly Monthly and Quarterly
    Yearly Monthly, Quarterly, and Yearly

    If you are an APM customer, who has upgraded to the Washington DC release, then the Daily frequency of Performance Analytics data source indicator is not available. RemoveDailyFreqAndUpdatePAIndicator fix script automatically removes the Daily frequency of PA indicators and updates the frequency to Monthly.

    Limitations to display application breakdowns in PA scoresheet

    If there is a large number of business applications installed, then all the breakdowns are not displayed in the Performance Analytics > Scoresheet, as there is a limitation set in the system properties: com.snc.pa.scoresheet.max_elements and com.snc.pa.scorecards.max_breakdown_elements. To reconfigure the property limitation:

    1. Navigate to Performance Analytics > System > Properties.
    2. Enter the maximum number in the Maximum number of elements of a breakdown in Scoresheet field. The number must be greater than or equal to the number of business applications installed in your system.
