What is SNMP?SNMP is a series of protocol groups and specifications. It provides a method to collect Network Management Information from devices in the network. SNMP also provides a way for devices to report problems and errors to network management workstations. The network mana

Java heap is not the same as the method area, where memory allocations are uncertain, and only when the program is running can you know which objects are being created, and this part of the memory and recycling is dynamic, and the garbage collector is concerned about this part of memory.Memory allocation and recycling in the "static" area is clear, but how does the "dynamic" area determine which memory to recycle and which memory should not? As we al
Java heap memory is divided into two parts of the new generation and the old generation, the new generation mainly uses the replication and labeling-clearing garbage collection algorithm, the old generation mainly use tag-sorting garbage collection algorithm, so in Java virtual for the new generation and the old generation of different garbage collectors, JDK1.6 in sun The garbage collector for the hotspot virtual machine is as follows:If the two garb

It is also necessary to perform basic monitoring on a single server or VPS. In the past, Zhao Rong did not monitor VPS, because when some servers were added, his performance became even more tense. There are also a lot of foreign server performance monitoring websites, but it is a little difficult for people like Zhao Rong who rely on Google to read English. Therefore, we will share with you the simple server performance monitoring implemented by using SNMP
Configure SNMP on Debian or Ubuntu
To install the SNMP agent (SNMPD) on a Debian based system, run the following command:
The code is as follows:
root@server:~# Apt-get Install SNMPD
Then, edit the configuration file as follows.
The code is as follows:
root@server:~# vim/etc/snmp/snmpd.conf
# Make SNMPD listen and all the interfaces

First of all: to define their own MIB, first familiar with the ASN.1 syntax, which has a foreigner's MIB book is very good, MIB's RFC document is it defined as if.
Second: See more other MIB, in fact, the definition is relatively simple, is type, scalar, table three main things.

early January 2015. I got a call from a teacher in Huawei and asked me to help with the app they used at the Beijing show, which can show Huawei's network equipment running state and set up some simple parameters, including AP, LSW, AP, AR and so on. The Huawei teacher told me that they were managed using the V2C version of the SNMP protocol, which meant that I had to implement the Protocol on my Android device and interact with their network devices.
