SG300-28PP FindIT Network Probe causes high CPU load and https error log entries

Hi guys,

 

first of all I want to apologize my bad English, I´m German and it´s not my mother language.

 

I am owner of a SG300-28PP with newest firmware and it runs smoothly in our house. Some weeks ago I thought of changing the switch into a unifi product (us-24-150W) just because its is easier to track errors or see whats going on. But, i love my cisco and it´s performance especially when moving big data from one VLAN to another. So after weeks of taking research I found the FindIT Manager and Probe. I downloaded and configured the Virtualbox versions which run on a Debian 9 PC.

 

As soon as I start the Probe i get high CPU load of about 60-80%. Yes, just the Probe. Same happens if I start only the Manager. I get every 5 minutes (i think so) entries in the error log. I tried everything i found worldwide. HTTPS and HTTP as service are enabled, am using SNMPv2, network is getting discovered and shown (only VLANS/"clouds" aren´t showing all subnets).

 

How can I get rid oh these errors please, any help would be appreciated much.

IP .31 is the manager, 32 the probe, 30 the host, switch .254

 

I don´t understand where it comes from. Certificate error ? I have no own signed certificates or changed anything belonging this. In addition to this, I am getting multiple "Warning health level" notifications in FindIT and whole switch/webgui is getting slower. I wouldn´t need to change the switch if I could get this to work.

Is it possible to view in console or by snmp query the CPU temp and memory usage ? Also, is it possible to view VLAN to VLAN traffic with Findit ?

 

Many thanks in advance and beste Gruesse ! :-)
