Instant Graphs

The Data tab enables you to select the indicators for which you want to view, analyze, and interact.

Perform the following steps to set the instant graph settings for Data tab.

Example

The Analyze tab enables you to define settings for the data you retrieve (such as, aggregation, baseline, time-over-time, units, work hours, etc.) and to use data analysis features.

Perform the following steps to set the widget settings for Analyze tab.

1. Units
   1. Select Bits for network-oriented data or Bytes for server-oriented data.
   2. Select the Use percentage check box to compare capacity or leave clear to compare the relative values of the different metrics.
2. AGGREGATION
   1. Enable Enable aggregation to aggregate the data to produce more readable graphs. Disabling this option displays the raw data. If Enable aggregation is disabled or if you are using custom aggregation, it may hinder the performance or prevent from producing results / rendering the widget.
   2. Enable the Use auto check box to have SevOne Data Platform use the aggregation that best fits your screen resolution.
      Warning: The Use auto option is enabled by default. If you disable auto-aggregation (by clearing the check box), you may experience significant performance issues. If necessary, only advanced users should disable auto-aggregation.
   3. Click the Type drop-down and select one of the following options:
      • Average - to display an average aggregation that is true to the data.
      • Maximum - to graph the highest value.
      • Minimum - to graph the lowest value.
      • Percentile - to show the percentile value.
      • Total - to aggregate all data.
   Important: If the Use auto option is not enabled, then configure the following fields.

   • In the Size Period field, enter the amount of time you want to collect data before data is saved and a new bucket is created.
   • Click the Size Units drop-down and select the unit of measure for the aggregation size time period.
3. SUMMARY SERIES

   Summary Series aggregates and summarizes alike series in the chart. Series with matching indicator types are summarized.

   1. Enable Summarize Series to view a summarized aggregation of the data.
      Note: This option is not supported when graphs are split (Instant Graphs) or if more than one unit type is present in the data.
      • Enable Hide Original Series to only show new aggregated series. When disabled, Hide Original Series shows both the original and the new aggregated series.
      • Click the Summary Aggregation drop-down and select which aggregation function you want to use for the summary. Periodicity matches the AGGREGATION setting. Select one of the following options:
        • Average - to display an average aggregation that is true to the data.
        • Maximum - to graph the highest value.
        • Minimum - to graph the lowest value.
        • Total - to aggregate all data.
4. DOWNSAMPLING
   1. Enable Enable downsampling to present the most important information while maintaining responsiveness when working on very large data sets or smaller graph spaces. While preserving meaningful peaks and valleys, downsampling intelligently excludes extraneous data points that do not impact visualization. For additional details on downsampling algorithm, please refer to the Ramen-Douglas-Peucker Algorithm.
5. BASELINES
   1. Enable Enable baselines to display each indicator's baseline on the graph. SevOne Data Platform automatically computes baselines. Baselines appear on the graph as dashed, light colored, box shaped lines. The Number of standard deviations enables you to enter a standard deviation multiplier that displays the measure of dispersion in a frequency distribution equal to the square root of the mean of the squares of the deviations from the arithmetic mean of the distribution. This applies to Line Graphs and Bar Graphs.
6. TIME-OVER-TIME
   1. Enable Enable time-over-time to display comparative data for a previous relative time span on the graph. For example, you may run a report for Monday with a time over time period of 10 weeks to display a line on the graph of the past 10 Monday's aggregated data.
   2. From the time over time type drop-down, select one of the following options:
      • Average - to display the average value for each aggregated data point in the corresponding timespan.
      • Maximum - to display the highest value for each aggregated data point in the corresponding timespan.
      • Minimum - to display the lowest value for each aggregated data point in the corresponding timespan.
      • Total - to display the sum of all aggregated data points in the corresponding timespan.
   3. In the Period field, enter the number of previous occurrences to aggregate for time over time comparison. Then, click the drop-down and select the Units of measure for the time period.
   4. Select Display only time over time data check box to display only the time over time line on the graph without any other indicator data. Clear the check box to display both indicator data and time over time data.
7. TREND
   1. Enable Enable trend to set trend Type and trend Algorithm. It computes a trend line using the data points in the graph.
   2. Click the trend type drop-down and select one of the following options:
      • Historical Trend - to trend data from the past to put data into perspective.
      • Projected Trend - to use past data to predict future data values.
        • In Days to project field, enter the number of days into the future to project the trend. The default value is 7 days and the valid input range is 1 - 3650 days.
        • Lookback Aggregation - choose Aggregated to smooth the data used for calculating the projections or Raw to choose the raw data.
        • Lookback Time - specify the time range of data you want to be used to calculate the projection.
      • Standard Trend - to use the data within the specified time span to create a trend line.
   3. Click the Algorithm drop-down and select one of the following trend types from the list:
      • Exponential - to display a curved trend line for data values that rise or fall at increasingly higher rates.
      • Linear - to display in linear trend line. Data is linear if the data point pattern resembles a line. A linear trend line typically shows that something increases or decreases at a steady rate.
      • Logarithmic - to display a logarithmic trend line for a curved line that is most useful when the rate of change in the data increases or decreases quickly and then levels out.
      • Power - to display a curved trend line to compare measurements that increase at a specific rate.

8. PERCENTILE

   1. Enable Enable percentile to determine the percentile value at which <x> percent of the data lies below. This is a useful statistical mechanism to remove data spikes to assist telecom companies, Internet Service Providers, etc. with billing their customers and to provide for true quality data. If enabled, enter the percentile value in the Percentile field for SevOne Data Platform to use to compute data.
   2. Only Show - allows you to show percentile results where the conditions meet Above or Below the value entered. Or, you can leave it as N/A to show all results.
9. WORK HOURS & MAINTENANCE WINDOWS
   1. Enable Enable maintenance windows to draw maintenance windows that affect the current resources.
      • Select the View global windows check box to show maintenance windows that do not have any associated resources.
   2. For Work hours, choose from one of the following options to select the work hours group for the data to appear in the report attachment.
      • None - to include all data for the device.
      • Device - to include data for the work hours that you associate with the device on the SevOne NMS Edit Device page. For additional details, please refer to SevOne NMS User Guide.
      • Custom - to display fields that enable you to define custom work hours.
   3. For Time, by default timespan / time zone selected is Past 24 hours New_York. Click the button to change the timespan / timezone. Select one of the following options:
      • Past n hours, days, weeks, months, quarter, year to display data from hours, days, weeks, months, quarter, or year ago until now.
      • Today - to display data from 12:00am today until now.
      • Yesterday - to display data from 12:00am yesterday until 12:00am today.
      • Last week, month, quarter, year - to display data from 12:00am on the first day of the last completed week, month, quarter, or year to 11:59pm on the last day of the last completed week, month, quarter, or year.
      • This week, month, quarter, year - to display data from 12:00am on the first day of the week, month, quarter, or year until now.
      • Customize the time span with From and To date / time.
      • Click Select button to choose the modified timespan / time zone.

• Click to force a refresh on the graphed metrics. Or, click in to select the time based on which the graphed metrics will refresh. For example, 30 seconds, 1 minute, 2 minutes, 5 minutes, or 10 minutes. By default, it is set to Off.
• displays the data coming from the selected resources for all the indicators in the past 24 hours.
• allows you to split the graph by Indicator Type, Unit, or Device.

  Let's say that Graph split is set to Indicator Type. Data series that share the Indicator Types are grouped onto the same chart.

  Once a Graph split option is selected, new charts are rendered based on the option and the resources selected. You can find the number of graphs in the upper left of the control bar based on the option chosen.

  Under Data tab in the example above,

  • Datasource = SevOne
  • Device group = All Device Groups
  • Device = Armonk-1, Armonk-2, Armonk-3
  • Object = IP of device - Device IP
  • Indicator Type = Average ping time, Maximum ping time, and Minimum ping time for each device selected

  This created statistical graphs for the object (IP of device - Device IP) and indicators (Average ping time, Maximum ping time, and Minimum ping time) on devices, Armonk-1, Armonk-2, and Armonk-3.

  

  Note: In the example above, it returns 9 rows; 3 rows for Armonk-1 - one for each indicator type, 3 rows for Armonk-2 - one for each indicator type, and 3 rows for Armonk-3 - one for each indicator type.

  Now, split the graph by Indicator Type.

  3 Graphs Total in the control bar indicates that the graph has been split into 3 graphs based on the option and resources selected in this example.

  

  By default, the graphs will appear as a List.

  

  To display the graphs as a Grid, click .

  

  Note: Graph split splits the data into multiple graphs based on the option chosen from the drop-down. Indicator Type as shown in the example above.

  List mode displays graphs in one column whereas, Grid mode displays graphs in two columns.

  To display as a List, click .

• Click to reset the options back to their default values i.e., selected resources, data analysis settings, display mode, page refresh, graph split, etc.
