AttacksProcess Killer Attack
The Process Killer Gremlin kills targeted processes over a supplied interval throughout the length of the attack. This Gremlin can select a set of processes identified by a regular expression, or specific processes identified by their process ID (PID).
Linux
The Process Killer Gremlin sends the signal supplied by --signal (defaults to KILL) to processes identified by the rest of the supplied arguments.
This Gremlin requires the KILL capability, which is enabled for Gremlin by default at installation time. See capabilities(7)
