cacti 流量超过100M的图像无法显示问题解决办法

cacti有的模板不能监控流量超过100M的网口，导致图像断断续续

 

我们可以通过rrdtool 来更改rrd文件。

现在进入查看该图像的rrd的位置console》Management》Data Source

 

首先查看1162.rrd的信息
[root@cacti bin]# ./rrdtool info /var/www/html/cacti/rra/99/1162.rrd |more
filename = "/var/www/html/cacti/rra/99/1162.rrd"
rrd_version = "0003"
step = 60
last_update = 1313657227
header_size = 3496
ds[traffic_in].index = 0
ds[traffic_in].type = "COUNTER"
ds[traffic_in].minimal_heartbeat = 120
ds[traffic_in].min = 0.0000000000e+00
ds[traffic_in].max = 1.0000000000e+07
ds[traffic_in].last_ds = "67776062880125"
ds[traffic_in].value = 1.0566749437e+08
ds[traffic_in].unknown_sec = 0
ds[traffic_out].index = 1
ds[traffic_out].type = "COUNTER"
ds[traffic_out].minimal_heartbeat = 120
ds[traffic_out].min = 0.0000000000e+00
ds[traffic_out].max = 1.0000000000e+09
ds[traffic_out].last_ds = "35061603641319"
ds[traffic_out].value = 3.9850907102e+07
ds[traffic_out].unknown_sec = 0
rra[0].cf = "AVERAGE"
rra[0].rows = 500

 

更改流量百兆为千兆

[root@cacti bin]# ./rrdtool tune /var/www/html/cacti/rra/99/1162.rrd -a traffic_out:1000000000
[root@cacti bin]# ./rrdtool tune /var/www/html/cacti/rra/99/1162.rrd -a traffic_in:1000000000

再次查看1162.rrd的信息

[root@cacti bin]# ./rrdtool info /var/www/html/cacti/rra/99/1162.rrd |more
filename = "/var/www/html/cacti/rra/99/1162.rrd"
rrd_version = "0003"
step = 60
last_update = 1313657227
header_size = 3496
ds[traffic_in].index = 0
ds[traffic_in].type = "COUNTER"
ds[traffic_in].minimal_heartbeat = 120
ds[traffic_in].min = 0.0000000000e+00
ds[traffic_in].max = 1.0000000000e+09
ds[traffic_in].last_ds = "67776062880125"
ds[traffic_in].value = 1.0566749437e+08
ds[traffic_in].unknown_sec = 0
ds[traffic_out].index = 1
ds[traffic_out].type = "COUNTER"
ds[traffic_out].minimal_heartbeat = 120
ds[traffic_out].min = 0.0000000000e+00
ds[traffic_out].max = 1.0000000000e+09
ds[traffic_out].last_ds = "35061603641319"
ds[traffic_out].value = 3.9850907102e+07
ds[traffic_out].unknown_sec = 0
rra[0].cf = "AVERAGE"
rra[0].rows = 500

cpu的图像也是一样，可以同理修改

./rrdtool tune /var/www/html/cacti/rra/113/1591.rrd -a cpu_idle:1000
./rrdtool tune /var/www/html/cacti/rra/113/1592.rrd -a cpu_nice:1000
./rrdtool tune /var/www/html/cacti/rra/113/1593.rrd -a cpu_system:1000
./rrdtool tune /var/www/html/cacti/rra/113/1594.rrd -a cpu_user:1000
