What’s New in MPA: Voice Quality Cause Visualization

Mitel Performance Analytics lays the groundwork for successful voice quality (VQ) troubleshooting with visualizations that tie performance data points together and point you towards the cause of a problem.

For most, troubleshooting voice quality (VQ) problems takes time, can be difficult to pinpoint and is a constant challenge for IT professionals. Often, these issues arise because of other problems on the network but the bottom line is that it’s your responsibility to find and fix them.
Mitel Performance Analytics does the work for you, gathering voice quality data and displaying it in a way that helps you spot trends and identify root causes.

Call Quality by Call Volume: See what happens to call quality as call volume increases and decreases through the day. This graph can help point you towards a capacity problem, when call volume and the number of bad or poor calls increase at the same time.

VQ Metrics Include:

• number and percentage of good, fair, poor, or bad calls
• hour of the day they occurred
• total number of calls

Call Quality by Directory: Displays as a table or chart showing the number of calls with bad or poor quality for the 10 worst directory numbers associated with a device.

Worst Performing Directory Numbers: See at-a-glance the percentage of poor quality calls for the 10 worst directory numbers associated with a device.

Worst Voice Quality Devices: This query displays as a table or chart the number of calls with bad quality for the 10 worst devices in a container, helping to point you towards the devices that need attention.

Diagnosing and correcting your VQ problems can have a significant and positive impact on your user’s experience.

We know that monitoring and managing performance offers a better user experience, decreases downtime, and lowers the cost of support. MPA’s voice quality graphs help to point you towards the cause of a problem for faster resolution.

What’s New in MPA – Network Diagrams

How long did it take you to troubleshoot your last voice quality problem? 90% of the time it takes to resolve a problem is spent identifying its source. The introduction of Network Diagrams for MPA makes it easy to visualize the source of a voice quality problem by teaming a clear ‘birds eye’ view of your network with health status icons, so you can see where the problems are at-a-glance.

With Network Diagrams You:

• Use your own Network Diagram (Visio).
  Get a different perspective on viewing collected alarms.
• Have a quick reminder of what your network looks like.
• Can see the health status over the devices being shown.
• Can filter container and device alarms and quickly jump to the container or device to see more detail.

How Does it Work?
The Network Diagram panel lets you upload your own network diagram to MPA with network devices and containers arranged to your preferences.

As an administrator, you might want to see a diagram of:

• devices based on the physical location
• devices based on the logical distribution
• separating groups of devices based on either VLANs, as a cluster, or as a nested grouping
• monitored devices with surrounding equipment not monitored by MPA

In the Network Diagram panel, MPA overlays health status icons over the devices being monitored. The health status icons are linked to the alarm filter, just like the Location Map panel, the Alarms panel, and the device hierarchy at the left of the dashboard. This means you’ll see only the alarms that are most important to you: for example, only major or critical.

From the Network Diagram panel, you can display the alarms of a specific container or device. You can also jump to a container or device dashboard to see more detail.
Quickly gain insight into:

1. Which device is experiencing a problem?
2. What’s causing the problem:
       Is it a capacity issue?
       Is something misconfigured?
       Do I have a network fault?

With Network Diagrams you can visually identify at a glance, where issues are located on the network.
