softnet-stat

Parse the /proc/net/softnet_stat file into something more readable. For more information about /proc/net/softnet_stat, I suggest reading Monitoring and Tuning the Linux Networking Stack: Receiving Data.

Compatible Systems

This parser should work on all Linux kernels since v2.6.32. In later versions of the kernel, more fields were added. Currenty, the parser will default these fields to a value of 0 if they are not found in the file.

Distribution

The softnet-stat binary is distributed via the hjr3/softnet-stat repository on packagecloud.io
