安装SNMP

#yum install net-snmp net-snmp-utils -y

#service snmpd start

#snmpwalk -v 2c -c public localhost

#snmpnetstat -v 2c -c mypublic -Can -Cp tcp 127.0.0.1

RRDtool

#yum install rrdtool -y

#rrdtool create test.rrd --step 5 DS:testds:GAUGE:8:0:U RRA:AVERAGE:0.5:1:17280 RRA:AVERAGE:0.5:10:3456 RRA:AVERAGE:0.5:100:1210

#rrdtool info test.rrd //查看

#vim rrd.sh

#!/bin/bash

while true;do

rrdtool update test.rrd N:$RANDOM

sleep 5

done

#rrdtool fetch -r 5 test.rrd AVERAGE //查看每隔5秒的平均数据

#rrdtool graph a.png --step 5 -s 1486666900 -t Test -v vtest DEF:vtest=test.rrd:testds:AVERAGE LINE1:vtest#ff0000:testline

#rrdtool graph b.png -s 1486666900 -t Test -v vtest DEF:vtest=test.rrd:testds:AVERAGE:step=5 DEF:vartest2=test.rrd:testds:AVERAGE:step=50 LINE1:vtest#ff0000:testline LINE1:vartest2#00FF00:testline2
