Puppet is using high CPU usage!!!

[Amrit Atmajit]

Hi,

We are using high end setup for our Puppet and foreman in CentOS server: RAID5, 198GB RAM, 64 cores Processor.

But, after installation of Foreman-installer puppet is eating the CPU like anything. We can observe CPU usage% is spiking > 4000!!!!!

Is it because of RAID5 processor? Can anyone help on this to resolve this issue?

At 64 cores, the load average comes out to .4 per core. Somebody correct me, but that actually seems fairly low.

That said, if you want to pursue this further, I would suggest implementing something like this to give you a better idea of your Puppet Server health:
