COROSYNC-CMAP(8)

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: [^[^]]<key_name>[ <type> <value>]
: Keys prefixed with single caret ('^') are deleted (see -d).
: Keys (actually prefixes) prefixed with double caret ('^^') 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]
