In the process of using CactiEZ, it is often impossible to add monitoring host or add host when SNMP information SNMP error occursFirst, the first is to determine that the cacti monitoring host can ping the monitored host, if not ping, please confirm the network configuration and the monitored host IP settings are correct. Second, if you can ping through, then confirm that the monitored Host is enabled SNM
Several methods for testing network SNMP connections (several solutions that I normally use to debug SNMP programs)
1. How to know which ports on this machine are active.There are two tools to help you understand which ports are open in your system.One is to enter "Netstat-an" at the command line to see which ports are active.The other is using the FPort tool, which is also used under the command line to
Objective: To obtain desired information from the snmp Agent device through the development of the net-snmp snmpget source code
Prepare: Download The net-snmp-5.6.1.1.tar.gzsource code package from http://www.net-snmp.org/net.
Development Process:
1. decompress the source code
2. Go to the directory for extracting the source code.

1. Four components of TCP/IP-based network management
(1) Management Information Library (MIB), which contains all the parameters that the Agent process may query or modify, that is, the parameters of the managed object.
(2) management information structure (SMI). management information is a collection of managed objects. SMI defines a rule set maintained by a device and is used to name and encode managed objects.

SNMP protocol Overview
SNMP (Simple Network Management Protocol) is a Simple Network Management Protocol, which provides a framework for the network management system to manage the underlying network. The SNMP protocol is widely used in many types of network devices, software, and systems, mainly because it has the following features:

In large network management, the headache for network administrators is how to know the running status of network devices that are not around in real time. To view the running status of network devices on one machine, it is obviously not very realistic. Here I will introduce you to a method that uses the SNMP protocol to automatically help administrators collect network running conditions. In this way, the network administrator only needs to sit on hi
Protocol-SNMP.
Elements of the network management system
A typical network management system includes four elements: Administrator, management proxy, management information database, and Agent service device. Generally, the first three elements are required, and the fourth element is only optional.
1. Administrator)
One of the important functions of the network management software is to assist the network administrator in managing the entire network.
Snmp Simple Network Management Protocol
The predecessor of the Simple Network Management Protocol (SNMP) is the Simple gateway monitoring Protocol (SGMP), which is used to manage communication lines. Subsequently, SGMP was greatly modified, especially when SMI and MIB compliant with Internet definitions were added: the improved protocol was the famous SNMP.
