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 Monitor tab has two main views: The "Summary Report" and the "Live Report".
This view is loaded by default and shows a summary of vital quality parameters over a user-defined time period. By default, the summary view shows the present day’s call details. 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 "Summary Report" has:
The Call Volume graph showing the volume of calls that were successful or unsuccessful, of good 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 Traffic Monitor graph showing a split-up of bandwidth for each VoIP traffic component
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, unsuccessful and waiting 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 and Poor quality calls. Calls with MOS (Mean Opinion Score) greater than 3.1 are classified as Good Quality Calls. Calls with MOS less than 3.1 are marked as Poor Quality Calls
The unsuccessful calls are further 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
The number of Unmonitored Calls during the chosen time-period is listed. 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
Answer Seizure Ratio(ASR) - ratio of successfully connected calls to attempted calls is displayed
The waiting calls are the number of calls that remain or remained in waiting mode at the chosen time frame. Calls in waiting mode are those that have been initiated but are yet to get connected with the called party.
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 – R Factor, Delay, Jitter, Packet Loss and MOS 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. Upto 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 deselect parameters to have the required additional parameters 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 R Factor, Delay, Jitter, Packet Loss and MOS 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 and get to the Summary Report view
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, R Factor, MOS
Click on Update button to confirm the values
Note: 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.
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.

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.
This view shows you the latest state of all vital quality parameters of your network. The information presented here is as on the time displayed next to the “Page Generated On” label found just below the line of tabs, on the right side of the screen. The ‘page generated’ time is given in the format: yyyy-mm-dd hh-mm-ss. You can have the Monitor tab generate the latest information by clicking on the “Refresh Page” button found next to the 'Page Generated On' time display.This setting for the live report's data display can be done using the two fields “Show Last” and “Refresh Every” found just below the line of tabs.
The "Live Report" view has:
The Live Calls graph which shows the number of Active calls and Attempted calls happening in the network
The Voice Quality graph having the recent values of important voice QoS metrics
The Traffic Monitor graph showing the the split-up of bandwidth for each VoIP traffic component
The Total Alarms section shows a summary of alarms generated over the chosen time-frame.
The Live Report can have data of the last 5 minutes to the last one hour to be displayed in the various graphs. Also, you can define the rate at which this view refreshes. This is done from the two fields “Show Last” and “Refresh Every” found just below the line of tabs.
To change the time interval for which the various graphs display the data, click on the Edit icon next to the "Show Last" field. On clicking this, a drop-down list is opened from which you can choose the required time interval. Select the interval and click the "Set" button. If no change is needed, you can click on the "Cancel" button to return to the existing setting.
To change the rate at which the Live Report view refreshes, click on the linked entry next to the "Refresh Every" field. You can choose the required page refresh rate from the entries in the drop-down list. Select the interval and click the "Set" button. If no change is needed, you can click on the "Cancel" button to return to the existing setting.
It displays the live calls as they happen in the network. Both Active calls and Attempted Calls are displayed.
Active calls are those that have both participant and initiator connected and exchanging data. These calls are distinctly referred to with Status Code 999 in the product.
Attempted calls are those that have been started off by the Initiator. These calls may progress to be Active/Successful/Error/Unanswered calls.
A green line shows "Active Calls" while the "Attempted Calls" are shown by an orange line. With this graph, you can know when individual calls were attempted, when calls became active and the progress of these calls in the defined time-period.
Provides also a count of the total number of currently active calls and the attempted calls over the defined time-period.
The "Call Rate" gives the rate at which calls are attempted over a given time period. You can find the rate at which calls happen on a per-hour/ per-minute/ per-second duration. This duration is chosen from the "Call Rate" drop-down list .
Provides trends of vital quality parameters – R Factor, Delay, Jitter, Packet Loss and MOS over the defined time period as set in the Live Report’s "Show Last" field
Upto 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 deselect parameters to have the required additional parameter’s trend graph displayed.
The Poor Value for all quality parameters is shown. (These values are those that were least in quality, during the "Show Last" period, for each QoS metric.)
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. The calls thus listed will contain both the active calls and the completed calls over the last 'x' duration as set in the "Show Last" field found on top of the Live Reports page.
Helps in finding out the traffic details (Bandwidth utilization) of the network managed by VQManager in a specific time interval as set in the 'Show Last' field of the Live Report view.
