Charts are used to plot various data sources like number of concurrent calls or quality of calls over time. Data sources can be combined to one chart allowing the viewer to see the correlation of desired data sources like SIP 4XX/5XX responses on ASR. The graph itself is interactive – clicking on a particular legend hides the datasource. Hovering on a datasource highlights it and shows the local value.
Charts are also present in the CDR window in the right mini-window sharing the same functionality with only difference that in CDR section the graph takes data from the current filter.
Add chart
To create new graph click on the + button.
Chart configuration
Chart configuration contains three tabs at the top – base chart data, filters – common and filters – rtp. The filters tab is used to filter data sources by various criteria – for detailed description please refer to CDR chapter.
The chart configuration panel is divided to three sections. Date range, series and description.
Templates
template field contains predefined chart configurations and custom templates which you can create / modify. To create new template - write name of it to description title field which shows save template button next to templates combo box.
Date range
Time interval
Time axes is density on the X axis.
series
Series section contains data sources for the charts.
series column
Series column chooses which data source will be plotted.
number of calls shows min/max/avg simultaneous calls distribution and total calls distribution *MOS / jitter / delay / packet loss shows RTP statistics *RTCP shows RTCP protocol values*ACD, ASR, PDD, SIP responses shows signalization related values*codecs shows codec distribution
ACD average shows averaged call duration for all calls which started in the given interval.
ACD immediate shows averaged call duration for all calls which are ongoing in the given interval. Thus this chart will show higher ACD for short intervals.
param
Param column specifies SIP response code
axis side
Axis side is used to assign data source to the left Y axis or to the right Y axis.
primary
Primary checkbox is used in case where more datasources are drawn on left or right Y. The primary checked datasource fills the whole Y axe and non-primary datasources use that scale. Here is example:
type
Type of graph
Line
Decoration for line type chart
Color
Color of chart
Fill / Markers / Smooth
Fill fills area below the line type chart
Markers plot dots at line
Smooth draw smoothes line instead of straight lines between points
Description
Description names graph, axis and sets legend position (top/left/right/bottom or no legend).
Setting your own title will allow to save a created graph for repetitive use. Once the title is filled or changed, the save button will appear next to type chart.
Filters - common
Filters CDR data in the same way as CDR filter formular except date range which is in the first base chart data section.
Filters - RTP
Filters CDR data in the same way as CDR filter formular
