Linux snmp+ monitoring treasure to achieve simple server performance monitoring

Monitoring treasure recommended use of NET-SNMP, so this article also take this as an example.

First, we install NET-SNMP.

The code is as follows	Copy Code
Yum Install Net-snmp net-snmp-devel net-snmp-utils

Next we start to configure NET-SNMP.

Before configuring, we need to confirm that SELinux is turned off (CentOS system attention), and then temporarily stop NET-SNMP

The code is as follows	Copy Code
Service SNMPD Stop

Then, add a read-only account (such as vpsaa.com), create a password (such as 123456), and transmit it in MD5

1	Net-snmp-config--create-snmpv3-user-ro-a 123456-a MD5 vpsaa.com

Next, start NET-SNMP

The code is as follows	Copy Code
Service SNMPD Start

Add NET-SNMP to the startup item

The code is as follows	Copy Code
Chkconfig snmpd on

Then we check the NET-SNMP

^? View Code LANGUAGE

1	Snmpwalk-v 3-u vpsaa.com-a md5-a "123456"-l authnopriv 127.0.0.1 SYSDESCR

If everything works, you'll see some information about the output.

Finally, because Zhao Jong here the server opened the iptables, so you need to add the monitoring IP address in the rule: 60.195.252.107 60.195.252.110

The code is as follows	Copy Code
Iptables-i input-p udp-s 60.195.252.107–dport 161-j ACCEPT Iptables-i input-p udp-s 60.195.252.110–dport 161-j ACCEPT

OK, finish the above work, we login our monitor treasure account (if not, please register, address: www.jiankongbao.com)

As shown above, select "Monitor" in the account-"server performance Monitoring", then click on the right "add Server", fill in the following figure the necessary information, and finally Add.

When you are done, you can click on the "Add Monitoring item" on the next page.

Finally, complete the server monitoring add, here should be noted that if you use to monitor the VPs, based on the OpenVZ architecture, the last disk IO will prompt "Your server does not support the monitoring project, please add Diskio module for the SNMP agent", OpenVZ users please cancel this item.
