NAME

corosync-cmapctl: - A tool for accessing the object database.

DESCRIPTION

usage: corosync-cmapctl [-b] [-DdghsTt] [-m map] [-p filename] [params...]

	-b show binary values
	-m select map to use

The default map is ’icmap’ which contains configuration information and some runtime variables used by corosync. A ’stats’ map is also available which displays network statistics - in great detail when knet is used as the transport. Tracking of individual keys (but not prefixes) works on the stats map but notifications are sent on a timer, and not every time a value changes.

Set key:

corosync-cmapctl -s key_name type value

where type is one of ([i|u][8|16|32|64] | flt | dbl | str | bin) for bin, value is file name (or - for stdin)

Load settings from a file:

corosync-cmapctl -p filename

the format of the file is: [ˆ[ˆ]]<key_name>[ <type> <value>]

Keys prefixed with single caret (’ˆ’) are deleted (see -d).

Keys (actually prefixes) prefixed with double caret (’ˆˆ’) are deleted by prefix (see -D).

<type> and <value> are optional (not checked) in above cases.

Other keys are set (see -s) so both <type> and <value> are required.

Delete key:

corosync-cmapctl -d key_name...

Delete multiple keys with prefix:

corosync-cmapctl -D key_prefix...

Get key:

corosync-cmapctl [-b] -g key_name...

Quiet output:

corosync-cmapctl [-b] -q -g key_name...

Display all keys:

corosync-cmapctl [-b]

Display keys with prefix key_name:

corosync-cmapctl [-b] key_name...

Track changes on keys with key_name:

corosync-cmapctl [-b] -t key_name

Track changes on keys with key prefix:

corosync-cmapctl [-b] -T key_prefix

Clear statistics (-mstats is implied)

corosync-cmapctl -C [ipc|totem|knet|all]
