Finally, I found the door.
SuggestionsFirst, the theoretical knowledge of network management must be available, and RFC.Second, let's take a look at the essence area. There is also a friendly connection, especially the snmplink website, where you will find a lot of things.Third, you must have programming skills for engineering purposes (this is something I lack and it costs a lot)

SNMP is the abbreviation of "Simple Network Management Protocol" in English, and the Chinese meaning is "Easy network Management Protocol". SNMP is currently the most commonly used environmental management protocol. SNMP is designed to be protocol-independent, so it can be used on Ip,ipx,appletalk,osi and other transport protoco
This article describes in detail how to configure the snmp framework for the cisoc router. I believe I have read this article to understand the SNMP management framework and SNMP notification.

snmp is certainly the first choice. After all, it can obtain too much information!
The following describes how to install, configure, start snmp, and perform remote testing on Ubuntu.
The operating system used here is: Ubuntu 15.10
--------------------------------------------------------------------------------
1. Install
We need to install the following three software packages:
Snmpd: snmp server software
Snmp: snmp client software
Snmp-mibs-downloader: software used to download and update the
information about the device. Note that all the information we get is windows and does not involve linux.
Note: here we also use the MIB asoning MIB Browser to work with our experiments.

This command indicates that the v1 version is used and the Community is public to walk the. 1.3.6.1.2.1.25.1.6 branch of
the local mib Library
Although I will use another host for remote testing, at the beginning, I installed the snmp client software on the server to facilitate some basic tests.
Run the following command to install the three software:
Ubuntu @ bkjia :~ $ Sudo apt-get install snmpd snmp-mibs-downloader

DescriptionAbout a complete tutorial, or that sentence, the domestic is either incomplete, or too old, and the idea is not clear, so here to write a complete for everyone to share.While the monitoring of Linux hosts can be done by executing specific commands, it is easier to get the Linux host's information by SNMP than after, but it is definitely worth the time it takes to configure the configuration before using it. And if you need to develop a Linux host monitoring software, that use of SN

When you run the above script, the data received and sent from your network device after the last restart is output in MiB. As shown below:

network management Workstation monitoring node is implemented by reading data on the managed node, while the management workstation can control it by writing data to the managed node. When a particular event is generated by the managed node, the managed node can send a simple network event message to the management workstation, which is called sending a trap and communicating between the management station and the managed node through the Network Management protocol.The basic principles of SNMP
. In the file is the network interface name, the second and third columns show the bytes received and transmitted (such as the total bytes sent, the number of packets, error statistics, and so on). We are interested in how to get the total data sent and received by different network devices. The next code listing shows how we can present this information from/proc/net/dev:

This is because PHP loads the above DLL (php_oci8.dll, php_pdo_oci.dll, and so on) at startup, and these DLL have external dependency information, for example, php_oci8.dll depends on the client component of Oracle8i, for detailed dependency information, refer to "dependencies ". This is because we installed all the compo
