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.

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

PARAMETERS

Fencing action (Default Value: reboot)
Method to fence (onoff|cycle) (Default Value: cycle)
The number of ping-probes that is being sent per target (Default Value: 10)
The number of positive ping-probes required to account a target as available (Default Value: 8)
The interval in seconds between ping-probes (Default Value: 1)
The number of failed ping-targets to still account as overall success (Default Value: 0)
A comma separated list of ping-targets (optionally prepended by 'inet:' or 'inet6:') to be probed (Default Value: )
The timeout in seconds till an individual ping-probe is accounted as lost (Default Value: 2)
Disable logging to stderr. Does not affect --verbose or --debug-file or logging to syslog.
Verbose mode. Multiple -v flags can be stacked on the command line (e.g., -vvv) to increase verbosity.
Level of debugging detail in output. Defaults to the number of --verbose flags specified on the command line, or to 1 if verbose=1 in a stonith device configuration (i.e., on stdin).
Write debug information to given file
Display version information and exit
Display help and exit
Separator for plug parameter when specifying more than 1 plug (Default Value: ,)
Wait X seconds before fencing is started (Default Value: 0)
Disable timeout (true/false) (default: true when run from Pacemaker 2.0+)
Wait X seconds for cmd prompt after login (Default Value: 5)
Test X seconds for status change after ON/OFF (Default Value: 20)
Wait X seconds after issuing ON/OFF (Default Value: 0)
Wait X seconds for cmd prompt after issuing command (Default Value: 3)
Sleep X seconds between status calls during a STONITH action (Default Value: 1)
Count of attempts to retry power on (Default Value: 1)
