In this generation if you are using an Linux System then you should have basic knowledge to debugging on performance side, Hence here I am providing you few commands list with the information of how to use and how the output of that. As a QA Engineer in Networking domain I am very well aware of the how is hard and needed to know debug an Linux System Performance related problems are coming in the client side along with needed to check during the Performance Testing after being withing the 3 years in IT industry.

SNMP or the Simple Network Management Protocol first emerged as a solution for managing nodes within a network. Since then SNMP data has been used to measure the performance of devices across countless vendors to help ensure that networks stay up and running. Today SNMP is one of the most popular networking protocols in the world and snmpwalk has become a go-to method for scanning multiple nodes at once. How Does SNMP Work? You can go through my article for this as How snmp work.

There are many different commands that...
