List commands
URI Template
GET /api/mdb/{instance}/commands
{instance}
Yamcs instance name.
Query Parameters
q
The search keywords. This supports searching on qualified name or alias.
system
List only direct child sub-systems or commands of the specified system. For example when querying the system "/a" against an MDB with commands "/a/b/c" and "/a/c", the result returns the sub system "/a/b" and the command "/a/c".
When
system
andq
are used together, matching commands at any depth are returned, starting from the specified space system.details
next
Continuation token returned by a previous page response.
pos
The zero-based row number at which to start outputting results. Default:
0
limit
The maximum number of returned commands per page. Choose this value too high and you risk hitting the maximum response size limit enforced by the server. Default:
100
noAbstract
Exclude abstract commands
Response Type
