[Xen-API] How to get the host (slave) and vm real-time metrics(e.g. cpu_utilization)

[Will Sun <willsun810@xxxxxxxxx>]

HiÂall,

IÂbuildÂaÂpoolÂincludesÂ3ÂhostsÂÂ:ÂvGate7ÂvGate8ÂvGate9.ÂÂvGate9ÂisÂtheÂmaster,othersÂareÂslaves.

IÂbuildÂaÂpageÂtoÂshowÂtheÂhostÂandÂvmÂmetrics(e.g.Âcpu_utilization)ÂonÂtheÂsameÂpage.ItÂworksÂfineÂforÂtheÂmasterÂ(vGate9)Â.ButÂitÂcannotÂgetÂtheÂslaveÂmetrics.

AsÂfollows:

InÂpython,IÂuseÂtheÂfollowingÂcodes to get the CPU Usage:

IÂattemptÂtoÂmakeÂanÂAPIÂcallÂtoÂaÂslaveÂ(evenÂsomethingÂtrivialÂlikeÂpool.get_all()),ÂIÂgetÂthe ['HOST_IS_SLAVE' ] exception,ÂalongÂwithÂtheÂmaster'sÂIPÂaddress.

TheÂmainÂproblemÂisÂtoÂget three hostsÂreal-timeÂperformingÂmetricsÂandÂtoÂshowÂthemÂonÂtheÂsameÂpage.Â

IsÂthereÂanyÂworkaroundÂtoÂsolveÂthisÂproblem?ÂThankÂyouÂinÂadvance!

Best Regards!
