Chart from Prism with blank interval

Hi 

By the looks of it, it seems like a service responsible for polling stats crashing/restarting at a fixed interval but it might need further debugging to further understand this issue.

I would request you to open up a support request with Nutanix Global support team.

Do you know the services name that could be responsible of this ? I'm thinking of hyperint but not sure.

Hyperint service is responsible for getting stats from hypervisor which are then polled by arithmos service. Artihmos service publishes all stats to prism.

So most likely it will be arithmos but we would need to take a look at the logs to confirm our diagnosis.

After reading from arithmos log, I cannot found any intel indicating a malfunction of this service.
There's a lot of line like this:
