The "Monitor" tab is the first UI that appears after connecting the Web Client. It provides a consolidated view of current state of the VoIP network as seen in the selected view port. It is like a dashboard from where you can get to know about all the important parameters at a glance - that is, everything needed to monitor the health of your VoIP infrastructure from a single screen.
The dashboard view loaded by default shows a summary of vital quality parameters over a user-defined time period. By default, the present day’s call details are shown. You can have a summarized view of calls that have happened over a defined time period by selecting the required date range from the calendar component on the top left hand corner.
The "Monitoring tab" has the following:
The Call Volume graph showing the volume of calls that were successful or unsuccessful, of good, tolerable or poor quality, the peak and low usage periods, the Average Call duration and overall ASR(Answer Seizure Ratio) etc..
The Voice Quality graph that shows snapshot of the QoS metrics with their Min, Max and Avg values and whether good, tolerable or poor as defined by the user.
The Call Quality Trend graph shows the quality parameter - Good, Tolerable and Poor quality calls on an hourly basis
The Call by Status is a pie chart showing the percentage and number of Successful, Unanswered, Error and Un-monitored calls.
The Traffic Monitor graph showing a split-up of bandwidth for each VoIP traffic component. Available only for Sniffer configuration.
The Total Alarms section shows a summary of alarms generated over the chosen time-frame.
Displays the statistics of all the calls that were initiated in the chosen time frame as set in the calendar.
The bar graph has the green areas representing the successful calls while the red areas denote unsuccessful calls.
Provides the number of call attempts, successful and unsuccessful as a linked number. When these linked number are clicked you can view the information of the respective calls.
The successful calls are divided into calls based on quality - Good, Tolerable and Poor quality calls. Calls with MOS (Mean Opinion Score) greater than 3.6 are classified as Good Quality Calls. Calls with MOS less than 3.1 are marked as Poor Quality Calls. Calls with MOS between 3.1 and 3.6 are marked as Tolerable Quality calls.
Answer Seizure Ratio(ASR) - ratio of successfully connected calls to attempted calls is displayed
Lists the time period at which there were a maximum number of calls - its peak usage ; Similarly, time period at which the call volume was minimum - low usage
Provides the average call duration time across all the calls during the selected time period
The Call Rate is provided showing the rate at which the calls are being made in the VoIP network
Output Formats
The call volume graph can be generated in three formats - a simple bar diagram, a three-dimensional bar diagram and a simple line graph
Click the respective icon on the top-right corner of 'Call Volume Graph' to get the respective view
Choosing the Time Interval
The Call Volume graph represents a summary of the calls that have happened over the time period as chosen in the calendar. You can split this time-period into intervals according to your requirement.
For example, if you have set the calendar to display past one month’s call summary, you have the option of splitting the graph into intervals of 7 days (4 bars), or 15 days (2 bars) or for the whole month (1 bar) itself.
You can select the required time-interval using the drop-down "Plot data every" available under the graph.
Provides trends of vital quality parameters – Delay, Jitter, Packet Loss, MOS and R Factor over the defined time period as set in the calendar.
A table of information shows the "Min", "Max" and "Avg" values for each quality parameter and also which of these values were "Good", "Tolerable" or "Poor" as defined by the user.
Trend graphs are displayed for each parameter. Up to three graphs can be displayed at the same time by selecting the respective check-box next to each parameter. On reaching the maximum of three graphs displayed, you need to de-select parameters to have the required additional parameter’s trend graph displayed.
Each individual QoS value plot on the graph can be clicked to provide details of the calls that have contributed to the respective QoS value.
Choosing the Time Interval
The Voice Quality graph represents a summary of the QoS statistics of the calls that have happened over the time period as chosen in the calendar. You can split this time-period into intervals according to your requirement.
For example, if you have set the calendar to display past one month’s call summary, you have the option of splitting the graph into intervals of 7 days (4 plot-points), or 15 days (2 plot-points) or for the whole month (1 plot-points) itself.
You can select the required time-interval using the drop-down "Plot data every" available under the graph.
Configure QoS
The QoS metrics can be customized according to the your VoIP quality requirements. The system administrators can define the threshold value for the Delay, Jitter, Packet Loss, MOS and R Factor value. The minimum and maximum value of tolerable value helps in determining the good and poor quality score. QoS metrics below the minimum threshold level would be classified as "Good" while the metrics exceeding the maximum threshold value will be termed "Poor".
To configure QoS metrics tolerable range
Go to "Monitor" Tab
Click on the "Configure" link, below the "Voice Quality" graph
A screen to "Configure QoS Min/Max thresholds" pops up
Fill in the tolerable range of various metrics like Delay, Jitter, Packet Loss, MOS
Click on "Update" button
to confirm the values
Note: 1. QoS metrics below the minimum threshold level would be classified as "Good" while the metrics exceeding the maximum threshold value will be termed "Poor". However for MOS metrics vice versa of this rule will apply. 2. After re-configuring the QoS thresholds in Configure link, the changes will take effect in the latest data to be collected. The history data will not get altered inline with new thresholds. This may lead to data mismatch on the day of re-configuring |
Call Quality Trend shows the quality parameter - Good, Tolerable and Poor quality calls on an hourly basis.
Each individual Quality Trend plot on the graph can be clicked to provide details of the total number of calls for the selected time period.
Helps to identify the percentage and number of Successful, Unanswered, Error and Unmonitored calls on a day to day basis as set in the calendar.
These parameters are represented in a pie chart with respective color codes.
The successful calls is shown in green and includes Good and Poor quality calls.
The Unsuccessful calls are divided into Unanswered calls and Error calls. Calls that were not answered by the user (user busy, user not available etc.,) fall into the Unanswered Call category. Other calls that failed due to errors in server or client are marked as Error Calls
Unmonitored calls are those that VQManager has abruptly stopped monitoring - this could be due to an abrupt stop and restart of the VQManager server, or because there were no voice packets that were received for a continuous duration(30 seconds) of time.
Hover over the pie chart to view the total number of successful, unanswered, error and unmonitored calls for a day.
When the linked percentage for the parameter is clicked you can view the information summary of the respective calls.
Note: The Traffic Monitoring Graph is available only for Sniffer data input option. |
Helps in finding out the traffic details (Bandwidth utilization) of the network managed by VQManager in a specific time interval as set in the calendar.
The traffic information is plotted in two sets of graphs. One set depicts the total size(in kbps) of the packets transmitted and the other set provides the total number of packets transmitted per second(packets/sec).
The bandwidth utilized by various components such as SIP, Skinny, H.323, Voice and Others are depicted each by individual graphs.
A table of information shows the " Min", "Max" and "Avg" values for each traffic component.
Output Formats
The Traffic Monitor graph can be generated in two formats - an area graph and a three-dimensional pie diagram.
Click the respective icon on the top-left corner of 'Traffic Monitor Graph' to get the respective view
Choosing the Time Interval
The Traffic Monitor graph represents the bandwidth summary of the calls made during the time-period as set in the calendar. You can split this time-period into intervals according to your requirement.
For example, if you have set the calendar to display past one month’s call summary, you have the option of splitting the graph into intervals of 7 days (4 plot-points), or 15 days (2 plot-points) or for the whole month (1 plot-point) itself.
You can select the required time-interval using the drop-down "Plot data every" available under the graph.
This summary of alarms is found in the left side of the UI, below the "Quick Links".
Provides the summary of alarms generated for the time period as set in the calendar. All categories of alarms: "Clear", "Warning", "Major" and "Critical" are shown including the "Total Alarms" generated in the selected time period.
You can view more details of respective alarms by clicking on the linked number next to the alarm name.
