[smokeping-users] Smokeping graphs from VMware slave is "choppy"

I don't know what operating system you are using, but make sure you have the guest tools for VMWare installed. Some operating systems like FreeBSD require you to disable APIC as well in order to correct issues with the clock. I use FreeBSD VM's with smokeping running on top of Windows quite regularly inside customers' networks, and those are the two keys to making it work.

Subject: [smokeping-users] Smokeping graphs from VMware slave is "choppy"

I'm running the latest code on both my Master and the Slave servers.

I suspect there is some time synching issue involved, but when I moved my slave to a VMware image, I started getting choppy graphs.
I don't see any errors in the logs, nor any loss of connectivity that the graphs are implying. I can ping continuously with no loss between the slave/master and between the slave and the targets during the blank periods on the graphs.  The logs show every 9-10 minutes the "Data Sent, server said OK" message from the slave.  The Master is also slated to be moved to a VMware image, but I'm holding off until I understand this issue.  The extra "smoke" is also a concern as the continuous pings don't show this variation in latency.

Has anyone else had anything similar?  Is there any additional data I can gather and send that will assist in getting this resolved (rrdtool dumps)?
