In this section:

Live Monitor is a configurable dashboard tool that displays a range of graphs for both real-time monitoring and historical performance monitoring. Each graph can be configured individually to change the time range and other parameters, such as, call cause codes and call duration. Some graphs can be customized to show data for specific zones, trunk groups, or IP Interfaces. All users except Security Auditors and CALEA users have the ability to view the Live Monitor window.

Live Monitor can be opened either from the Live Monitor link on the home EMA window, or using the following path:  Monitoring > Dashboard > Live Monitor

Enabling or Disabling Live Monitoring (Polling)

Data collection for Live Monitor can be enabled or disabled at any time. By default data collection is disabled. When enabled, data is retrieved from the Call Count Status table to retrieve all the active calls on SBC. The Data is polled at frequent intervals (every minute).  To retrieve active calls for specific zones and trunk groups, the Call Current Statistics table is used. This data is polled every 15 minutes. 

 To enable/disable Live Monitoring, on the Live Monitor window, click the desired option as shown in the following figure.

Enable-Disable Live Monitor

 
Note:

Live Monitoring can't be enabled on a sytem with less than 6 CPUs and less than 16 GB RAM.

 Live Monitor data purging occurs on either a disk-space or age basis: 

  • Disk-based purge - Occurs when the database reaches a system-defined percent of the overall partition size. Disk-based purging takes precedence over aged-based purging.
  • Age-based purge - Occurs when the data is older than a system-defined time period.
Note:

In HA deployments, Live Monitoring configuration parameters and data on the Active system are also available on the Standby system. However, during a failover, some of the Live Monitor data may not be saved to the database.

Configuring Live Monitor Settings

Administrators and Operators have the ability to change the settings for Live Monitor and for the individual charts on the page.

To select which Live Monitor metrics appear on the Live Monitor window and optionally specify data targets:

  1. Click Configure Live Monitor. A configuration pop-up window opens. 
  2. Click on metrics to move them between the Available Metrics and Selected Metrics lists. Live Monitor displays charts for the metrics in the Selected Metrics list.
  3. Use the drop-down list of numbers on the right of each metric to select the number of instances (up to 5) of the chart to display. The default is 1.
  4. Select Collect data from selected zones and trunk groups below to open lists where you can select the data targets if you want to collect data from specific zones, trunk groups or IP interfaces.
  5. Click OK.

Live Monitor Settings

 The settings for the Live Monitor screen apply to all users. If one user changes the settings for Live Monitor or for an individual chart, the same change is applied for all EMA users.

The following metrics can be monitored by Live Monitor:

  •  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

Configuring Time Duration for Each Graph

Click Settings on top of the graph to configure.

Settings

Select the time duration from the Display graph for drop-down list and click OK. The minimum time period is 1 hour and the maximum is 7 days.

Types of Graphs

Licensed Service Usage

This graph displays the number of calls on all the zones and trunk groups for the selected time duration. 

Active - Licensed Calls

Active Calls per Zone/Trunk Group

This graph displays the number of calls for the selected zones and trunk groups for the specified time duration. Maximum of 4 zones and/or trunk groups can be shown on each chart. 

Active Calls

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.

Viewing CDRs

  1. To view the CDRs for a specified duration, click and drag the duration.

    Selected Short Duration Calls

  2. After making the selection, click Troubleshoot.

  3. The CDR Viewer screen is displayed with the relevant data. Click Back to Live Monitor to go back to Live Monitor window.

Long Duration Calls

This graph displays the number of long duration calls for the specified time duration. A long duration call is defined using the Show calls longer than field under Settings. Calls longer than the specified duration are classified as long duration calls. Show calls longer than field value range is 5 mins to 120 mins.

To view the CDR data, follow the same procedure as in Short Duration Calls.

Call Disconnect Reason

This graph displays the number of disconnected calls for a specified reason and time duration. The reason can be selected from the Call Disconnect Reason drop-down list under Settings.

To view the CDR data, follow the same procedure as in Short Duration Calls.

Call Attempts/Call Completions and Call Attempts/Call Completions per Zone/Trunk Group

Call Attempts/Call Completions graph displays the number of calls attempted and the number of calls completed for a specified time duration.

Call Attempts and Call Completions

 

Call Attempts/Call Completions per Zone/Trunk Group graph displays the number of calls attempted and the number of calls completed for a specified time duration and zone/trunk group.

Bandwidth Allocated and Bandwidth Allocated Per IP Interface

Bandwidth Allocated graph displays the available bandwidth for all the IP interfaces for the specified duration.

Bandwidth Allocated

 

Bandwidth Allocated Per IP Interface graph displays the available bandwidth for the specified IP interfaces and duration.

Bandwidth Allocated Per IP Interface

Bandwidth Usage and Bandwidth Usage Per Zone/Trunk Group

Bandwidth Usage graph displays the usage for all the zones and trunk groups for a specified duration.

Bandwidth Usage

Bandwidth Usage Per Zone/Trunk Group displays the usage for specified zone and trunk group.

Graph Characteristics

Live Monitor graphs have the following general usability characteristics.

Tool Tips are enabled on the graphs to provide details when a mouse is hovered on it.

Auto-refresh rates: The data in charts auto-refreshes at regular intervals based on the range selected for the chart. For example:

    • If the 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 the range is 3, 6 or 12 hours, the charts refresh every 15 min.

    • If the range is in days, the charts refresh every hour.

Persistence: Every individual chart is persistent. The settings for each chart and the number of charts is saved automatically between logins.

  • No labels
