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]
