You can use the API endpoint
/mgmt/tm/sys/provision/stats
as Satoshi gave previously.
Mgmt information is represented by the 'host' line in the iControlREST response.
In the example below,
host
is given 10% CPU, this is what is remaining after
tmos
has 84% and each module has 1%. (I have formatted the output below as the response is given as a one liner)
{
"kind": "tm:sys:provision:provisioncollectionstats",
"selfLink": "https://localhost/mgmt/tm/sys/provision/stats?ver=12.1.3.7",
"apiRawValues": {
