Trends


Note: Trends are displayed on the Service Manager Home page via a Service Apps app. Service Apps must be installed. To find out more, please contact your EasyVista consultant.
Definition

A trend is a key figure related to the company's IT activity for a given period. It is based on directly observable and measurable quantities, or calculated using data.

It can be used as a monitoring tool to measure changes. It can also be used for forecasts and decision-making.

EndDefinition
  • The configuration of the trend will depend on its type.
  • When enabled, it will run based on the frequency defined.
  • Trends are displayed on the Home page via a Service Apps app (subject to access rights). You define the formatting, i.e. color, data format, charts, etc. in the app.
  • Trends can be stored in folders that are organized by function.

Type of trends

Standard trends

  • They are built around a parent query.
  • A filter enables you to extract only the data you want.
  • The result of the trend is calculated based on the number of records retrieved by the filter. It can also be the sum or the average of field values for the records retrieved by the filter.

example  

  • Number of immediate resolution incidents today trend ==> Result based on the number of records retrieved by the filter
  • Average late time for incidents solved today trend ==> Result calculated using the Late field for records retrieved by the filter

Ratio trends

  • The result of the trend is calculated using the values of two other trends.

example Define an objective of 20% of immediate resolution incidents ==> Ratio calculated using the following:

  • Number of immediate resolution incidents today: Trend 1
  • Number of incidents created today: Trend 2

Notes

  • You can create or modify a trend as long as you are authorized to access the Administration > Trends > Trends menu.
  • Display trends via an app:
    • To create the app, you must have Service Apps.
    • To display the app in Service Manager, you must have access rights to the app.
  • Parent query of a trend:
    • You can only create it without any specific user rights when creating a trend.
      • The new parent query will be available for all Service Manager internal reporting tools, e.g. trends, alerts, reports, and purges.
      • It will not be available for parent queries used to define standard Service Manager objects, e.g. forms, lists of values, filters, quick filters, views.
    • You can modify it as long as you are authorized to edit display presentations. Open url.png See User Profiles > Edit rights and display rights.
      • Manually added fields will be available for all reporting tools and purges.
      • They will not be available for parent queries used to define standard Service Manager objects.
  • Access rights to the app displaying the trends are defined in Service Apps.
  • If the calculation of a trend is not triggered, check that the Scheduler is started and correctly configured.

Caution

  • If you delete a trend, its history will be completely deleted. If you want to stop calculating it temporarily, you should disable it using the relevant wizard. This way, its history will not be lost.

Best Practice

  • Use a KPI widget to display the history of a trend. It provides a quick overview of changes using Widget KPI - Tendance Indicator.png icons and a miniature trend chart, EVApps - Widget KPI - Small Bar chart.png or EVApps - Widget KPI - Small Line chart.png.
  • When you create a trend, you should backdate its start date so that it will run immediately. This enables you to check the results immediately without waiting for the first execution date. This will also initialize its history and its display on the Home page.

    example  

    • Current Date: 10 February.
    • First execution date: 1 March.
      ==> In the Next Compute Date field, enter the first day of the month prior to the current date, i.e. 1 February.
  • If the running of trend B depends on the completion of trend A whose processing time is unknown (due to large data volumes, access time, etc.), we recommend that you schedule the tasks in a sequence instead of defining a specific time for running trend B.
     

Ensuring optimal network performance

  • Schedule the calculation of complex trends during periods where users do not need to access Service Manager, i.e. at night or on weekends.
  • If you work in an international organization with different service hours for each country, you may want to run the calculation of trends in a specific environment, instead of in the production environment.

Characteristics specific to versions 2016 and earlier

The trends in versions 2016 and earlier are different.

  • Edit rights are assigned to each user profile in the module associated with the menu item using the trend. Open url.png See User Profiles.
  • Trends are displayed on the Home page of the associated menu.
  • Once thresholds have been specified for each domain, users can analyze results quickly thanks to the icons (Smiley good value.png, Smiley average value.png, Smiley bad value.png, Trend - Arrow tendance positive Green.png, Trend - Arrow tendance negative Red.png) and quantitative scale that displays segments graphically in different colors. Open url.png See the description.
  • When a trend is recalculated, the value displayed is not stored in the database. It is displayed and stored as long as the session is open.
  • Calculation history
    • It can be displayed in a chart and exported in a CSV file.
    • You can manage its display or delete it on the Home page.
    • By default, the number of values displayed in the trend's history is 15. You can modify this value in Other Parameters.

Frequency: Used to define the frequency for calculating the trend.

  • The frequency will be applicable after the date specified in the Next Compute Date field. 
  • The parameters depend on the selected frequency.
    • Every [N] Months / Day / At (Hour): Define the relevant frequency using Universal Time (UT).
    • Depends on: Used to sequence the running of two trends successively. Select the trend whose processing precedes the execution of your trend from the drop-down list.

Next Compute Date (Note: Only if the frequency is not Depends on): Date and time at which the trend should next be calculated.

  • The date initializes the start of the frequency.

    example  Frequency: Every seven days at 7 am; the next compute date is a Saturday ==> The trend will run every Saturday

  • You can also update the date using the Enable wizard.

    Best Practice icon.png  Enter a date earlier than the current date in order to run the calculation of the trend immediately.

History Management: Used to indicate if the trend's calculation history should be stored (box is checked) or not (box is not checked).

  • You can click Delete history icon.png to delete the history in List mode.
    • You can reinitialize the start date of the history.
    • The last value in the history is stored.

Dividend / Divisor (Note: Only for  Ratio  trends): Trends used to calculate the percentage value of the current trend.

  • Percentage value of the trend = 100 * (Dividend trend / Divisor trend).
  • You must first define the trends.

example  % of unsolved incidents every month trend

  • Dividend trend = Number of unsolved incidents this month = 9
  • Divisor trend = Number of incidents created this month = 72
    ==> Percentage value of the trend = 100 * (9 / 72) = 12.5% unsolved incidents this month 

Note: The two fields below are not used in Service Manager versions later than 2016. You define the configuration in the Service Apps app displayed on the Service Manager Home page.

  • Domain: List of domains where quantitative thresholds are applicable.
  • Thresholds: Thresholds in a quantitative scale of values based on the result of the calculated trend.
     

Number of Records / Totals / Average (Note: Only for Standard trends): Used to indicate how the trend is calculated.

  • You can only choose one option.
  • The Totals and Average options only apply to numeric fields in the parent query.
  • Number of Records: The result is equal to the number of records that satisfy the filter criteria of the trend.

    example  Number of incidents created this week trend

    • Result = 61  ==>  61 incidents created this week
  • Totals: The result is equal to the sum of records that satisfy the filter criteria of the trend.

    example  Total intervention time for immediate resolution incidents today trend - Total calculated using the Solution Delay field 

    • Snapshot of today's incidents: Four immediate resolution incidents with an intervention time of 10 minutes; one with an intervention time of 30 minutes
    • Result = (4 * 10 min) + (1 * 30 min) = 70  ==>  Total intervention time is equal to 70 minutes.
  • Average: The result is equal to the average of values from the selected field for all records that satisfy the filter criteria of the trend.

    example  Average late time for incidents solved today trend - Average calculated using the Late field 

    • Snapshot of today's incidents: Four solved with a delay of 1 hour; one solved with a delay of 5 hours; one solved with a delay of 3 hours
    • Result = [(4 * 1h) + (1 * 5h) + (1 * 3h)] / 6 incidents = 2  ==>  Average late time for incidents solved is equal to 2 hours.
