I am currently planning the monitoring of a switch and would like to consider beforehand what I need to be closely monitored in order to obtain errors and warnings are also useful.
I have a Cisco SG200-50 and activated with the current firmware also SNMP. With snmpwalk I can already read the properties are only so many that it is very confusing. It would be tedious to go through each leave and so to gather the information together. I would like the CPU load and the traffic as a graph yet also monitor errors and warnings for all ports can be output.
Now to my questions.
- With what SNMP objects can I monitor the traffic
- To what object I find Packet error or CRC Errors
- How can I display the CPU load and see what process is responsible
This information I would like to represent as a graph, because someone has already practical examples or do I really need the search all together yourself?
