When it comes to network management protocols, the Simple Network Management Protocol (SNMP) is probably one of the best known. It is commonly used in networks and several applications internally support SNMP for monitoring purposes.
In this section, we will only provide a short overview of SNMP because its full workings are beyond the scope of this book.
