1. Can PRTG monitor how many clients currently connect to a server (linux preferably)?

2. I got probem when trying to add sensor for Bandwidth/Traffic for Linux/MacOS. It says SNMP error #222. How to solve it? Below is the log of my SNMP Tester.

To monitor the number of linux users you will need to create a custom SSH sensor since there are no built-in sensors for this.

Custom SSH Sensor

Show linux logged in users

From the output that you posted here, it looks like SNMP isn't enabled for that Linux or Mac computer. To read SNMP values from a Linux system, the SNMP subsystem has to be activated.

for the case error #222.

is there any different SNMP setting between SNMP uptime and traffic? because I can monitor the SNMP uptime for such machine.

This is another snmp walk on 1.3.61.2.1.1 | I hope there is answer why I still can't monitor the bandwidth/trafic on my linux machine.
