We should found all SNMP relatives topics at here.

RFC 1157 Simple network management protocol

RFC 1158 Management information base for network management of TCP/IP-based internets.

RFC 1161 SNMP over OSI

Traditional Chinese version wiki of SNMP.

The SNMP V2 was defined in RFC3416,RFC3417 and RFC3418.

The SNMP V3 is defined in RFC

You can found MIB information in RFC1213

Sometimes,we using remote monitoring to control a remote-host via RMON which protocol is defined in RFC 2819.

Network management :

What is FCAPS : Fault Management, Configuration Management,Accounting Management,Performance Management and Security Management.these conceptual areas were created by ISO(International Organization of Standardization)

Fault Management:

The goal of FM is to detect, log, and notify user of system of networks of problems.In many environment,downtime of any kind is not acceptable.

FM dictates that these steps for fault resolution be followed:

1. Isolate the problem by using tools to determine symptoms.

2. Resolve the problem.

3. Record the process that was used to detect and resolve the problem.

While step3 is important, but is often not used! Not using this step 3 may cause new engineers who following step 1 and step 2 being in the dark , at this time, they have to consult the DBA or the manager.

Configuration Management

The goal of CM is to monitor network and system configuration information,so that the effects on network operation of various versions of hardware and software can be tracked and managed.

Any system may have number of interesting parameters that engineer my be interested in capturing,including:

1.Version of operating system,firewall, etc.

2.Number of network interface and speeds, etc.

3.Number of hard disks.

4.Amount of RAM.

This information generally is stored in a database of some kind. As configuration parameters change foe systems ,the database is updated. An added benefit to having this data stores is that it can aid in problem resolution.

Accounting Management

The goal of AM is to ensure the computing and network resources are used fairly by all groups or individuals who access them.

Throught this form of regulation,network problem can be minimized since resources are divided base on capacities.

Performance Management

The goal of PM is to measure and report on various aspects of network or system performance.

The steps of Performance Management:

1.Gather performance data.

2.Establish baseline levels based on the data gathered.

3.Establish thresholds,and when these thresholds are exceeded, it is indicative of a problem that requires attention.

Security Management

The goal of SM is twofold.First,we wish to control access to some resource.Second ,we wish to help detect and prevent attacks that can compromise networks and hosts.

SM encompresses not only network security but also physical security.
