Monitor Network Performance
from Anywhere

Troubleshoot network performance issues from your smartphone with our free mobile app for Android and iOS, or our web app.

Experience the next generation of network monitoring and debugging. Sonar Lite gives you complete visibility of your domains from dozens of geographically unique locations within the Constellix network. Identify bottlenecks, verify connectivity from different locations, and root out network latency.



View all the network hops between your desired monitoring location and any server or FQDN (Fully Qualified Domain Name). This tool is great for troubleshooting location specific latencies. Just run a few traceroutes from different monitoring nodes to narrow down the source of network issues. You can also use traceroutes to identify bottlenecks and points where traffic is falling off.
