In the thread below it says, "SNMP V1/V2, PING, PORT, and HTTP are the recommended sensor types for scenarios with thousands of sensors."
And, "For SNMP V3 PRTG is able to ... on a system with four cores, you can monitor around 10,000 sensors with 60 seconds interval."
I have just set up a probe on a dedicated machine with the following specs:
- 4 Core Intel Xenon E5620 2.4GHz Processor
- 4GB RAM
- 1TB HDD
On the probe I have 9700 sensors which are only ping and SNMP v2 sensors with a 60 second scanning interval. My issue is that the probe health sensor is down and 1/3 of the sensors on the probe are down.
The message said that there was:
- 700% Interval Delay non-WMI&SNMP
- 480% Interval Delay SNMP
- 499 Open Requests
My memory usage was 270MB and Probe Process CPU Load was around 18%
I left it like this over the weekend thinking that maybe the new probe needed time to catch up but there was no change when I came in this morning. I have just increased the scanning interval to 5 minutes to see what happens.
From what I've read the probe should be able to handle this load. Any ideas on what my be going wrong?
