Capacity Planner Release Notes 100

Overview

Released: May 2019

This release introduces improved visibility on server drive utilization, modelling of ‘residuals’ and enhanced capabilities to standard reports.

Highlights

Cluster headroom

Drive time series information can now be viewed from the headroom dialog window. To access it, open the window using the right-click option. A new tab will be presented on the lower half of the window.

The menu options for each drive allow you to view the time series data for that drive utilisation.

Residuals

A residual workload is one that represents work that the server is doing that is not captured by a monitoring tool and not reflected in the sunburst visualization. It is particularly important when modelling purely physical environments and multi-process applications. In this case, the sunburst will show servers and workloads representing processes running on that server. However, there may be a difference between the perceived activity of the server and the combined activity of the processes. This difference is known as the residual. The residual is not shown or accessible directly via the sunburst but can be visualized using reports.

High values of residual activity indicate that monitoring is not necessarily sufficient to capture workload on a server.

Reports

Enhancements have been made to the standard reports, allowing for further flexibility and visualization of data. A number of efficiency improvements have also been made to reduce execution times.

The changes introduce further parametrised options to tailor the report to your needs and adds the ability to run reports on all entity types with metric data in Capacity Planner, including residuals and networking entities (routers, switches, interfaces etc.) where appropriate.

Value-based filtering has been added on some reports to allow metric series or summaries to be reported on only where user-specified thresholds have been reached or exceeded. Date ranges can now be specified as relative to the date of the latest data received by Capacity Planner as well as relative to today’s date.

When filtering entities using grouping values, most charts now allow multiple values to be selected for each filter applied.

RAG operators now have a default option of [None] which means that RAG indicators are switched off. This will mean that amber and red RAG threshold lines will not be shown and the RAG indicator column in the Metric Analysis – Multi Chart report will be hidden. Setting the operators and specifying RAG threshold values will cause the lines and indicators to appear. Note that behaviour is slightly different in the Linear Trend and Scatter Plot chart types

Metric Analysis reports now have options to show or hide capacity values to give more control over report appearance.

Metric analysis — multi-chart

This report has been enhanced to allow for further visualisations with a single chart presented per selected entity type (VM, cluster, host, drive, etc). Two of these (Linear Trend and Scatter Plots) calculate linear regression lines and associated intercept, gradient and R2 values.

Reports can be filtered and ordered by R2 values to allow the most significant to be identified. In these reports red and amber threshold values are used to calculate values on the best fit line allowing projected dates and values to be displayed. For example, in the Linear Trend report, the report display will show the projected dates at which amber and red threshold values would be reached.

The new chart types are:

  • Box plot — this chart can be used for daily summaries and above (day, week, month etc.). It shows percentile values as a box with whiskers above and below to indicate the range of value distribution. This is the only chart type that can show more than one percentile value. However, the Percentile/Value selector still controls the metric used for RAG thresholds.
  • Bar chart — values are shown as vertical bars.
  • Line chart — values are plotted as points on a line.
  • Linear trend — this chart plots metric values and linear regression line for any given metric. This chart should be used with hourly average or unaggregated data for shorter term trends. Longer term trends can make use of daily summary values.
  • Radar chart — this chart plots all entities on a single radar visualization. This chart works well for comparing metrics but we recommend to use it with a relatively small number of entities to improve readability.
  • Scatter plot (metric pairs) and scatter plot (metric pairs reversed) — these chart types appear in the drop-down list if two metrics are selected. They calculate linear regression lines based on metric pair values. Switching between these two report types reverses the X and Y axes of the report. Red and Amber threshold values calculate X axis values from the given Y axis values based on the regression line.
  • Stacked bar chart — this chart presents a single bar per date showing the relative metric values.

Metric analysis — single-chart

This report which shows all entities in a single chart has had further visualisations added:

  • Bar chart — values are represented as horizontal bars. The entity names, dates, and values can be sorted on the chart using the sort indicator .
  • Treemap — entities are shown as areas in a rectangle, with size of area representing the value.

Fixed issues

Previously it was not possible to filter the exported CSV list of events. A bug has been fixed that ensures only the visible events are exported. The user has the option to export all events or visible events.

When new grouping values are added to a project, any previously created baseline views that filter on that grouping would have the new value automatically selected. This has been resolved.

Physical Servers can now be found in sunburst searches.
