Hello,
I have a core switch with 2 Cisco 3750G that doesn't support Netflow, which is the best way to configure PRTG in order to monitoring Bandwidth, CPU usage, memory, network performance etc.
thanks

The lack of Netflow shouldn't be a problem, there's still a lot of stuff you can monitor since this model supports SNMP. You can employ at least the following sensors:
- Ping Sensor, to check whenever the device is reachable/accessible.
- SNMP System Uptime Sensor, to confirm that the device wasn't unexpectedly rebooted.
- SNMP Cisco System Health Sensor, to monitor various general metrics, memory, temperatures, etc.
- SNMP Traffic Sensor, to check for bandwidth and to get alerted regarding the status of interface (disconnected, disabled)
- SNMP RMON Sensor, for detailed packed-related statistics
And if that's not sufficient, you can always resort to custom sensors or MIB files from the vendor:
- Can't find a sensor for my device in PRTG but I believe it supports SNMP. How to proceed?
- What can I monitor with the SNMP Custom Table Sensor?
