I don't know why the net-snmp built-in in centos cannot catch a lot of information, and the CPU network traffic memory cannot catch it.
After a while, I decided to use the code to compile and pull it down.
Wget http://downloads.sourceforge.net/project/net-snmp/net-snmp/5.4.4/net-snmp-5.4.4.tar.gz? R = http % 3A % 2F % 2Fsourceforge.net % 2 Fprojects % 2Fnet-snmp % 2 Ffiles % 2Fnet-snmp % 2F5. 4.4% 2F & ts = 1316244916 & use_mirror = switch
. /Configure-sysconfdir =/etc/snmp-bindir =/usr/bin-sbindir =/usr/sbin-prefix =/usr-with-default-snmp-version = "2 ″ -disable-snmptrapd-subagent; make; make install
Note that make-j8 is not supported; otherwise, an error is reported.
The configuration file is in/etc/snmp/snmpd. conf. The content is as follows:
Agentaddresses udp: 161
