32Bit to 64Bit



How can we update a probe from 32bit to 64bit on the same server to improve performance. Can this be done on the main server without losing the devices too?

only the server part of PRTG can be installed as 64bit! The probe part of PRTG will stay 32bit.

When you install pr update PRTG on a 64bit OS that has 6GB RAM or more PRTG will automatically install as 64bit.

Only the PRTG Server.exe needs to benefit from the possibility to use more memory which the 64bit makes possible.

The PRTG probe.exe does not need this and would not benefit from it as well.

What performance issues are you facing?

We have a probe that monitors various VM's, hardware and network devices for a client (about 400 sensors 5 min poll) and setup dependencies on the ping polls so if the ping is lost the other sensors are paused. Since the upgrade to the latest version we keep on getting false positives many times through out the day. The CPU on the server which runs the probe often spikes with the prtg process (100%). We know that it isn't a network issue, but also have some probes installed with 600+ sensors with out any issue.

Would you recommend we split the probe?, as in install another probe to take the load of the initial one. Or could this be main server specific.

are all the VMware sensors on one probe?

Maybe we should make a support ticket out of this.
