Martin, can you list the verbs that mom is using?
Easily:
Those below are currently used by MOM directly:
getAllVmStats
vmSetCpuTuneQuota
vmSetCpuTunePeriod
getIoTunePolicy
getIoTune
setIoTune
setKsmTune
We also have some verbs that are used by the engine and forwarded to MOM:
setMOMPolicyParameters
setMOMPolicy
updateVmPolicy
Btw, about stats collection:
Balloon stats are collected by VDSM
KSM stats are collected by MOM and VDSM grabs them in
vdsm.momIF.MomClient#getKsmStats
Martin
Removing the verbs that nobody is using now can be nice progress.
