How does CNA work?
It relies on IoT sensors to gather reachability information to online services from the user point of view and proactively report on service degradation. The service provided is fully managed and does not require change to your current environment.
IoT sensors are used to emulate user activity and measure IT service responses.
Each element in the path is analysed to gain full visibility.
Online
Online is today’s default status. Everything we do, watch, buy, sell is online. The shift to the cloud and the advent of SaaS has made us cloud dependant, and with that, reliable connectivity is a must.
Slow is the new down
Business Critical Applications
Application reachability monitoring is the foremost use for CNA. The sensors emulate user consumption, often browser requests to websites, and business-critical applications.
When a single application is impacted, the issue is reported in the Top-Level dashboard with a change of colour (Red-Amber-Green) in the application tile. The example below shows four application tiles with SharePoint reporting problems.
The user experiences delay in loading the webpage, and – in SharePoint case - with uploading and downloading items.
A more detailed view shows how the problem manifests in high response time.
Name resolution
Humans can remember names, such as www.google.com, but the internet operates with numbers called IP addresses. DNS failure means delay or no IP address resolution for the destination name requested.
CNA sensors consume DNS services the same way the end-user does. The service intelligence is in the ability to report and validate the DNS response.
The graph below was captured during a DNS malfunction that affected all customer services. The graph shows that the DNS was responding with delays up to 1.5 seconds.
The DNS responses were also erroring – this can be seen in the “DNS1 – RCODE” table, and in the graph pop-up. DNS Response CODE is insightful information on what is affecting the DNS service.
Wireless
The floorplan view is very intuitive when representing the wireless service. The sensors report on the WiFi signal reading, and colour-changing icons can be used to represent the quality of the signal received. These can be made interactive, with pop-up graphs when hovering on top with the mouse.
The detailed view can highlight issues with the signal broadcasted and the availability of the Wi-Fi service to the users.
The graph below was capture during an intermittent availability of wireless signal, this was due to a code issue with the access-point.
Connectivity
Connectivity is the enabler for all the online activities. When compromised, access to the IT services is undermined and users experience is degraded.
Monitoring of connectivity is often isolated to the network devices, limiting visibility of the bigger picture. This is exacerbated by the disjointed support teams from the multiple providers.
CNA uses the data collected from the IoT sensors and data captured from the cloud monitoring system to evaluate the performance of the connectivity of your office, school, coffeeshop, etc.
The graphs in the pictures below show how the applications are affected by WAN problems. The WAN packet loss, reported on the bottom right graph, is reflected on the WAN Performance, bottom left graph, and on the application graphs on the top.
Connectivity has to be able to serve the required amount of throughput demanded by the user’s traffic.
If the bandwidth is suddenly reduced, the user’s traffic is constrained at a higher contention rate, resulting in drops and retransmissions. CNA sensor can monitor the bandwidth available on the WAN by running periodical speed tests.
