style="orphans:2;text-align:-webkit-auto;white-space:normal;margin-top:10px;margin-bottom:15px;border:0px;color:#333333;font-family:Helvetica, arial, freesans, clean, sans-serif;font-size:14px;line-height:22.3999996185303px;"> Cacti是用php语言实现的一个软件，它的主要功能是用snmp服务获取数据，然后用rrdtool储存和更新数据，当用户需要查看数据的时候用rrdtool生成图表呈现给用户。因此，snmp和rrdtool是cacti的关键。 </p> <p style="orphans:2;text-align:-webkit-auto;white-space:normal;margin-top:15px;margin-bottom:15px;border:0px;color:#333333;font-family:Helvetica, arial, freesans, clean, sans-serif;font-size:14px;line-height:22.3999996185303px;"> Snmp关系着数据的收集，rrdtool关系着数据存储和图表的生成。snmp抓到数据不是存储在mysql中，而是存在rrdtool生成的rrd文件中（在cacti根目录的rra文件夹下，一般以rra为后缀名称）。 </p> <h3
