Live Monitor screen is available as a configurable dashboard tool for displaying a range of graphs for both real-time monitoring and historical performance to aid fault-finding and troubleshooting at network wide and device level. Each graph settings can be configured to change the time range and other parameters on a per-graph basis, such as, call cause codes and call duration. Some graphs are can be customized to show data for specific zones, trunk groups, or IP Interfaces.
Live Monitor provides a snapshot view of the device at a quick glance. Data Collection for Live Monitor can be enabled or disabled at any time. By default Data Collection is disabled.
Calls are retrieved from Call Count Status table to retrieve all the active calls on SBC. To retrieve the calls, the Data is polled at frequent intervals (every minute). The data is fed to the database too for the users to view the Historical Data.
To retrieve Active Calls for specific Zone and Trunk Group, the Call Current Statistics table is used. The Data is polled at frequent intervals (every 15 minutes). This data is also available in the database for the users to view.
On the main screen, go to Monitoring > Dashboard >Live Monitor.The following metrics are monitored:
- Licensed Service Usage
- Active Calls per Zone/Trunk Group
- Short Duration Calls
- Long Duration Calls
- Call Disconnect Reason
- Call Attempts/Call Completions
- Call Attempts/Call Completions per Zone/Trunk Group
- Bandwidth Allocated
- Bandwidth Allocated per IP Interface
- Bandwidth Usage
- Bandwidth Usage per Zone/Trunk Group
Live Monitor supports High Availability:
- All Live Monitoring configuration parameters on the Active system are also be available on the Standby system.
- All Live Monitoring data on the Active system are also available on the Standby system.
| Note |
|---|
During the failover process, some of the Live Monitor Data may not be saved to the database. |
Live Monitor data purge on Disk basis and Age basis:
- Disk-based purge - When the database reaches a system-defined percent of the overall partition. Disk-based purging takes precedence over aged-based purging.
- Age-based purge - When the data that is older than a system-defined time period.
The settings for the Live Monitor screen apply to all users. If any one user changes the settings for the Live Monitor screen or for an individual chart, the same change is applied for all EMA users.
Access to Live Monitor page:
- All users except Security Auditors and CALEA users have the ability to view the Live Monitor page.
- Administrators and Operators have the ability to change the settings for the Live Monitor and for individual charts on the page.

The screen has the following features:
Ability to display live chart for the above mentioned statistics (list) over time.
Ability to enable or disable live monitoring (polling) for all the charts. By default, the polling is disabled.
- Ability to specify which Zones, Trunk Groups, and IP Interfaces from which data should be collected.
- Ability to add one or more charts to the Live Monitor Dashboard. A minimum of 1 and a maximum of 10 charts are allowed to display on the Dashboard.
- Ability to remove one or more charts from the Live Monitor Dashboard. At least one chart must be displayed on the Live Monitor Dashboard.
- Ability to select a specific area of a chart. Area selection is used to zoom in for all charts, and is also used for troubleshooting data for selected charts.
- Ability to allow selection of a range in a chart and analyze Data to CDRs to aid troubleshooting for Short Duration Calls, Long Duration Calls, and Call Disconnect Reason charts.
Ability to configure the time period for the data collection for each chart. The minimum time period is 1 hour and the maximum is 7 days.
Ability to add multiple instances (up to 5) for each chart.
Enabling or Disabling Live Monitoring (Polling)

Short Duration Calls
This graph displays the number of short duration calls for the specified time duration. A short duration call is defined using the Show calls shorter than field under Settings. Calls shorter than the specified duration are classified as short duration calls. Show calls shorter than field value range is 1 second to 45 seconds.

Auto Refresh: The data in the charts auto-refresh at regular intervals based on the range selected for the chart. For example:If display range is one hour, Trunk group, Zone, and IP Interface based charts refresh every 15 minutes, while all other charts refresh every one minute.
If range is 3 h, 6 h, or 12 h then the charts refresh every 15 min.
If range is 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days then the charts refresh every hour.
Persistent Charts: Every individual chart is persistent. That is, the settings for each chart and the number of charts are saved automatically between login
