FENCE_AGENT(8) System Manager's Manual FENCE_AGENT(8)

NAME

fence_heuristics_ping - Fence agent for ping-heuristic based fencing

DESCRIPTION

fence_heuristics_ping uses ping-heuristics to control execution of another fence agent on the same fencing level.

This is not a fence agent by itself! Its only purpose is to enable/disable another fence agent that lives on the same fencing level but after fence_heuristics_ping.

fence_heuristics_ping accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_heuristics_ping can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
