Onionprobe features

Monitor from anywhere

Onionprobe can monitor Onion Services from the "outside", i.e, it does not need to run on the same premises the Onion Services are running: the monitoring tool can be set anywhere on the Internet, as long as the Tor network can be reached.

Monitor any public service

Onionprobe allows monitoring any public Onion Service website: you don't have to be that onionsite operator in order to monitor it. The only thing you need is to know it's address.

Monitor many services at once

A single Onionprobe instance can monitor many Onion Services, making it suitable for large infrastructures as well as for researchers interested in collecting public available data on service reachability.

Get data that represents the user experience

Onionprobe's collected data better represents the actual user experience in terms of Onion Service reachability and performance. It does not collect fine grained server data like those exposed directly by the Tor daemon (like the MetricsPort option on C Tor), but it experiments the effective network latencies and intermittencies a user would face.

Runs out-of-the box

Onionprobe's standalone monitoring node comes with everything needed to test, measure and visualize Onion Service connectivity data, all batteries included.

Still, advanced Onion Service Operators can run just the core Onionprobe service, or even use it as a library in other applications. Check out the installation options for details.
