Scrutinizer NetFlow Analyzer

Scrutinizer NetFlow Analyzer is a comprehensive software application that provides you with detailed information about network usage for the hosts and apps which take up the most bandwidth.
It's accessible from a web browser and features a wide range of reports which you can study, together with alarms.

Configurable installer and web interface

In custom setup mode you can modify the default TCP port that the web server will listen for requests, and it's advisable to change it if you have Skype installed.
Furthermore, you can enter the TCP port that MySQL will listen and serve requests, the root password to the MySQL Server, and the default Scrutinizer user name and password for the administrator. Optionally, you can specify a read-only SNMPv1 community as your default community string (can be later changed).
Once launched in a web browser with the local host address, you are prompted for the admin user name and password, which can be remembered by the app for future logins. The tool contains multiple themes for the interface appearance, so you can select the preferred one.

Rich dashboard gadgets for network monitoring

The dashboard shows top interfaces, applications, countries, hosts, network transports and subnet traffic, in addition to recent alarms. Using flow analytics, the program is capable of filtering applications by flow version, device, interface, inbound or outbound traffic, or group. You can add as many filters as you want.
Likewise, the recent alarms shown in the graph may be filtered by policy, board name, violations, TI, HI, first or last event, or last notification. Moreover, Scrutinizer compiles a crosscheck list with each host, flow, poller and fault index, enabling you to define thresholds and third-party methods (Flow, Poller, WhatsUp, or custom).

Customizable gadgets, network maps, and alarms

You can examine a service level report and a graph with the crosscheck summary, along with data on CPU and RAM utilization, available storage, and the flow metric by exporter and listening port. New tabs can be added with database statistics, jitter or latency by interface, network volume, port utilization or errors, and other templates.
Another section of Scrutinizer is dedicated to creating network maps (Flash or Google groups) and populating them with other members. It's possible to tinker with connections (sending and receiving members, network interface), objects, the background image, dependencies, animation speed, font size and colors, labels, and other general aspects. What's more, you can check out alarms.

Evaluation and conclusion

The tool didn't hang, crash or display error messages in our tests. However, it was high-demanding in regard to the system resources, slowed down the web browser, and took a long time to load its modules. Nevertheless, Scrutinizer comes packed with feature-rich options and configuration settings for compiling detailed reports about network usage, dedicated to expert users.
