How to turn on a secure SNMP agent on a Linux server

Server monitoring tools help us to understand the performance and functionality of the server in real time from any location. Monitoring Bao Server monitoring suite, real-time CPU utilization, memory utilization, average load, disk I/O, network traffic, disk usage, etc., can bring you both short-term and long-term benefits.
Monitoring Bao currently provides the server monitoring projects include:
1. CPU utilization, monitor CPU usage ratio, including User State (username), kernel State (System), I/O wait (iowait), idle, etc.
2. CPU load, monitoring the average load of Linux servers (load average), including the last 1 minutes, 5 minutes, 15 minutes, etc.
3. Memory usage, monitoring memory usage, for Linux servers, including free memory, Buffer Cache, Page Cache, application memory, etc.
4. Disk I/O, monitor I/O traffic for all disk partitions, including write and read
5. Network traffic, monitoring the traffic of all network devices, including incoming and outgoing
6. Disk space usage, monitoring the space usage of all disk partitions, including total space and used space.
7. Number of system processes, monitoring the current number of processes in the system.

monitoring principle  
Monitoring Bao uses the standard SNMP protocol to provide server monitoring functionality to users, which means that the SNMP agent (SNMPD) must be running on the monitored server. Next we'll detail how to install, turn on the SNMP agent on a Linux server, and make the necessary security configuration.  
in the various Linux distributions, most of them have been integrated by default SNMPD, such as in Suse10, you can open snmpd: 
suse10:~ #/ETC/INIT.D/SNMPD start 
If there is no default installation, all you have to do is compile the snmpd yourself, follow the steps below, very simple.

compile, install, and security settings  
for Linux platforms, we recommend the use of NET-SNMP, which implements the standard SNMP protocol and includes agents as well as various SNMP tools.

Add a server to the surveillance treasure
Now let's take a look at how to add server monitoring in the monitoring treasure, through the new navigation, you will easily enter the page to add the server, here is divided into two parts, the first is to fill in the server information, including the server name and IP address, as well as the operating system type.
These are very simple, the reason to choose the operating system type, because there are some differences between Linux and Windows, so their SNMP repository is somewhat different, we need to provide the corresponding monitoring project according to different systems.

Next is the SNMP setup, which mainly selects different SNMP protocols and fills in authentication information.

Then click "Add Monitoring Project", you can select the monitoring project for this server, for Linux server, monitoring Bao currently provides the following monitoring items, you can check all, and then submit.

When you are finished, click the Submit button, and it will take some time for the monitor to use this information to try to connect to your SNMP monitoring agent, which is a very important step.

Bad, if you fill in the information can not connect to the server's SNMP agent, monitoring Bao will prompt you, this time, please carefully check the previous introduction of those configuration, as well as firewall policy, perhaps you do not open udp161 port.

If the connection is successful, you will see the success page when the problem is found.

then just wait for the data and charts, everything is so simple, if you have any questions or need help, please contact us: Http://www.jiankongbao.com/feedback
