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.

PARAMETERS¶

-o, --action=[action]

Fencing action (Default Value: reboot)

-m, --method=[method]

Method to fence (onoff|cycle) (Default Value: cycle)

--ping-count=[number]

The number of ping-probes that is being sent per target (Default Value: 10)

--ping-good-count=[number]

The number of positive ping-probes required to account a target as available (Default Value: 8)

--ping-interval=[seconds]

The interval in seconds between ping-probes (Default Value: 1)

--ping-maxfail=[number]

The number of failed ping-targets to still account as overall success (Default Value: 0)

--ping-targets=tgt1,[inet6:]tgt2

A comma separated list of ping-targets (optionally prepended by 'inet:' or 'inet6:') to be probed (Default Value: )

--ping-timeout=[seconds]

The timeout in seconds till an individual ping-probe is accounted as lost (Default Value: 2)

-q, --quiet

Disable logging to stderr. Does not affect --verbose or --debug-file or logging to syslog.

-v, --verbose

Verbose mode. Multiple -v flags can be stacked on the command line (e.g., -vvv) to increase verbosity.

--verbose-level

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).

-D, --debug-file=[debugfile]

-V, --version

Display version information and exit

-h, --help

Display help and exit

--plug-separator=[char]

Separator for plug parameter when specifying more than 1 plug (Default Value: ,)

--delay=[seconds]

Wait X seconds before fencing is started (Default Value: 0)

--disable-timeout=[true/false]

Disable timeout (true/false) (default: true when run from Pacemaker 2.0+)

--login-timeout=[seconds]

Wait X seconds for cmd prompt after login (Default Value: 5)

--power-timeout=[seconds]

Test X seconds for status change after ON/OFF (Default Value: 20)

--power-wait=[seconds]

Wait X seconds after issuing ON/OFF (Default Value: 0)

--shell-timeout=[seconds]

Wait X seconds for cmd prompt after issuing command (Default Value: 3)

--stonith-status-sleep=[seconds]

Sleep X seconds between status calls during a STONITH action (Default Value: 1)

--retry-on=[attempts]

Count of attempts to retry power on (Default Value: 1)
