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
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.
Live Monitoring cannot be enabled on a system with less than 6 CPUs and less than 16 GB RAM.
Live Monitor data purging occurs on either a disk-space or age basis:
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.
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:
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:
You can customize the graph output by adjusting its settings. Each type of graph can be set individually. The type of settings depend on the graph contents and include options such as specifying a time duration, or filtering the output for a specific license type or disconnect reason. Click Settings at the top-right of the graph to configure its settings. The following is an example of the control used to set time duration.
Select a 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.
Filter Capabilities:
This graph displays the number of calls on all the zones and trunk groups for the selected time duration.
Active - Licensed Calls:
The time duration and licensed entities to include in the graph are defined in Settings, as shown below.
Licensed Service Usage Graph Settings:
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:
This graph displays the number of short duration calls for the specified time duration. Calls shorter than the specified duration are classified as short duration calls.
Short Duration Calls:
A short duration call is defined using the Show calls shorter than field under Settings, as shown below. Show calls shorter than field value range is 1 second to 45 seconds.
Show Calls Shorter Than:
Viewing CDRs
To view the CDRs for a specified duration, click and drag the duration.
After making the selection, click Troubleshoot.
The CDR Viewer screen is displayed with the relevant data. Click Back to Live Monitor to go back to Live Monitor window.
This graph displays the number of long duration calls for the specified time duration. Calls longer than the specified duration are classified as long duration calls.
To view the CDR data, follow the same procedure as in Short Duration Calls.
Long Duration Calls:
A long duration call is defined using the Show calls longer than field under Settings, as shown below. Show calls longer than field value range is 5 mins to 120 mins.
Show Calls Longer Than:
This graph displays the number of disconnected calls for a specified reason and time duration.
To view the CDR data, follow the same procedure as in Short Duration Calls.
Figure 14: Call Disconnect Reason
The reason can be selected from the Call Disconnect Reason drop-down list opened from Settings, as shown below.
Figure 15: Call Disconnect Reason Field
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.
Call Attempts - Call Completions per Zone - Trunk Group:
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 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.
Bandwidth Usage Per Zone - Trunk Group:
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.
Tool Tip on Hovering:
Graph variables are color-coded for clarity.
Color Coded Graphs:
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.
