【问题描述】:
我创建了很多 RRDTool 图表来监控 Raspberry Pi 服务器的各个方面。
我将显示 36 小时、10 天、45 天和 18 个月的数据,例如传输的数据、CPU 温度、平均负载等。
但是,唯一看起来“连续”的图表是 10 天图表,所有其他图表中都有空白。我每隔一分钟记录每个数据点。
有 28 (29) 张图片,所以我不会把它们都放在这里,所以我把它们放在了imgur for your perusal
但这是我所说的一个例子:
10 天效果很好!
45 天,没那么多。
这是我的 .rrd 创建脚本:
rrdtool create data.rrd \
--start N --step '60' \
'DS:rx:GAUGE:60:0:U' \
'DS:tx:GAUGE:60:0:U' \
'DS:rxc:COUNTER:60:0:U' \
'DS:txc:COUNTER:60:0:U' \
'DS:wrx:GAUGE:60:0:U' \
'DS:wtx:GAUGE:60:0:U' \
'DS:wrxc:COUNTER:60:0:U' \
'DS:wtxc:COUNTER:60:0:U' \
'RRA:AVERAGE:0.5:1:129600' \
'RRA:AVERAGE:0.5:2:64800' \
'RRA:AVERAGE:0.5:60:14400' \
'RRA:AVERAGE:0.5:300:12960' \
'RRA:AVERAGE:0.5:3600:13140'
rrdtool create load.rrd \
--start N \
--step '60' \
'DS:load:GAUGE:60:0:4' \
'RRA:AVERAGE:0.5:1:129600' \
'RRA:AVERAGE:0.5:2:64800' \
'RRA:AVERAGE:0.5:60:14400' \
'RRA:AVERAGE:0.5:300:12960' \
'RRA:AVERAGE:0.5:3600:13140'
rrdtool create mem.rrd \
--start N \
--step '60' \
'DS:mem:GAUGE:60:0:100' \
'RRA:AVERAGE:0.5:1:129600' \
'RRA:AVERAGE:0.5:2:64800' \
'RRA:AVERAGE:0.5:60:14400' \
'RRA:AVERAGE:0.5:300:12960' \
'RRA:AVERAGE:0.5:3600:13140'
rrdtool create pitemp.rrd \
--start N \
--step '60' \
'DS:pitemp:GAUGE:60:U:U' \
'RRA:AVERAGE:0.5:1:129600' \
'RRA:AVERAGE:0.5:2:64800' \
'RRA:AVERAGE:0.5:60:14400' \
'RRA:AVERAGE:0.5:300:12960' \
'RRA:AVERAGE:0.5:3600:13140'
我的整个绘制脚本大约有 900 多行,所以我只在此处包含一组图形的实际绘制代码($RRDTOOL 是一个包含路径 /usr/bin/rrdtool 的变量):

是的,我知道其中一张图上的标题是错误的,我已经修复了这个问题,但只是在将所有图像保存到 imgur 之后。
