Arachne is a packet loss detection system and an underperforming path detection system. It provides fast and easy active end-to-end functional testing of all the components in Data Center and Cloud infrastructures. Arachne is able to detect intra-DC, inter-DC, DC-to-Cloud, and DC-to-External-Services issues by generating minimal traffic:
There are two ways to use the Arachne package.
Run Arachne as a standalone program (it's Debian packaged already too).
Import this package and call Arachne from your program/service with
where the option provided above is among the few optional ones.
Below is the list of all the CLI options available, when Arachne is used as a standalone program. The default options should be good enough for most users.

Arachne is granted access to raw sockets without the need to run with sudo or
as root user, by being granted
When receiving packets, Arachne attempts to apply a BPF filter to the raw socket so that processing of packets occurs on a much smaller set (ones destined specifically for Arachne agent testing). This is currently supported only on Linux and thus performance will be worse on BSD-based systems where a larger number of packets must be inspected.
