Hello all. Somewhat new to PRTG and rolling out sensors to monitor switches, firewalls, and Windows servers throughout our environment. About 100 Windows servers, and probably about that many network devices.
Anyway, I've started with WMI sensors for Windows servers and I've been using SNMPv3 for network devices. I am using a single Windows Server VM with 4 vCPU and 6Gb RAM. It's an older VM still running Windows Server 2012 R2. We have 2019 licensing and I'll likely upgrade that soon.
I have about 1400 sensors (60 devices) total out there now and am seeing the "PRTG Probe Service" (32 bit) fluctuate between 40 and 68% CPU utilization. I have a long way to go before rollout is complete and it appears my PRTG infrastructure isn't sized appropriately.
Question is.... (1) should I just give up on SNMPv3 and go to 2c? Will this save huge CPU on the PRTG server or does it not make a difference? (2) How many remote probes am I going to have to plan on deploying to get through this deploying approximately? Assuming moving to SNMP 2c won't allow me to stick with a stand alone PRTG server/probe.
