The SNMP service is often used in routine monitoring, while the snmpwalk command is the most effective method to test the system information. Some common methods are summarized as follows:
1. snmpwalk-C public-V 1-m all 192.168.30.49. 1.3.6.1.2.1.25.1.
2. snmpwalk-C public-V 1-m all 192.168.30.49. 1.3.6.1.2.1.25.2.2 get the total system memory

For the installation process, see the official documentation. The cacti requires an SNMP package for use. The installation method in centos is yum install net-snmp. This is no problem. When installing cacti, refer
, Snmpwalk will be used. The yum method is generally unable to install this file. Baidu later found that it is generally recommended to delete the snmp package installed on the small yum, then download the complete SNMP source code and
The Snmpwalk command is the most effective way to test the various information of the system, commonly used in the following ways:1, snmpwalk-c public-v 1-m all 10.0.1.52.1.3.6.1.2.1.25.1 get the number of system processes users on the Windows side, etc.2, snmpwalk-c public-v 1-m all 10.0.1.52.1.3.6.1.2.1.25.2.2 Get Total system memory3,
SNMP functions are not discussed, mainly to implement equipment monitoring.Installation of SNMP on the OpenWrt network is also a lot of the introduction of monitoring, but only through the Snmpwalk command to obtain the status of other devices are not introduced.Take a look at OpenWrt's wiki and find the installation method.The key is one sentenceInstall snmp-utilsThe status of the remote device can be tested after successful installation192.168. 1.1O
