Best practice use of probes to reduce system load.



Hi everyone,

I feel like my PRTG System is a little overloaded. The CPU and RAM usage is at 50% but still the overload protection kicks in (at least PRTG says that it does) and a few sensors got trouble receiving data.

I guess the problem here are the hundreds of WMI sensors we are using. To solve this, I thought about outsourcing the sensors of those systems by using Probes. That how every raises the question: What is the "best practice" to do this?

a.) Install an independent server with a probe to act like a satellite and collect Data from multiple other servers.

b.) Install a probe on each server itself to monitor that particular server.

c.) both or something else?

If the answer is b.) here is a follow up "issue": We have an exchange server and to monitor the DBs I have to use the Exchange-Database-Sensor (PowerShell). But I am not allowed to use this sensor (and probably some others too) since it requires an FQDN, but the probe seams monitor itself via IP (, how can I work around that?

Hi there,

I would recommend to choose option a). In this way you can split the load to multiple Remote Probes. In addition I would recommend to take a look at our guide for speeding up installations here.

Kind regards
