Question

我已经创建了很多监控Raspberry Pi服务器各个方面的RRDTool图。

我显示36小时，10天，45天和18个月的内容，例如转移数据，CPU温度，平均负载等。

然而，唯一的＆＃34;连续＆＃34;看图是10天图，所有其他图都有差距。我以微小的间隔记录每个数据点。

有28（29）张图片，所以我不打算把它们全部放在这里，所以我把它们放在imgur for your perusal上

但这是我所谈论的一个例子：

10天的工作正常！

45天，而不是那么多。

这是我的.rrd创建脚本：

rrdtool create data.rrd         \
--start N --step '60'           \
'DS:rx:GAUGE:60:0:U'            \

rrdtool create load.rrd         \
--start N                       \
--step '60'                     \

'RRA:AVERAGE:0.5:300:12960'     \
'RRA:AVERAGE:0.5:3600:13140'    

rrdtool create mem.rrd          \
--start N                       \

'RRA:AVERAGE:0.5:300:12960'     \
'RRA:AVERAGE:0.5:3600:13140'    

rrdtool create pitemp.rrd       \
--start N                       \
--step '60'                     \

我的整个绘制脚本长度超过900行，所以我在这里只包含一组图形的实际绘图代码（$RRDTOOL是一个包含路径/usr/bin/rrdtool的变量）：

是的，我知道其中一个图表上的标题是错误的，我已经解决了这个问题，但只是在将所有图像保存为imgur之后。

Answer 1

如果您选择60秒的--step，我会选择120的mrhb而不是60秒，因为rrdtool会忽略任何超过60秒的更新。

rrdtool create data.rrd         \
--start N --step '60'           \
'DS:rx:GAUGE:120:0:U'            \
'DS:tx:GAUGE:120:0:U'            \
'DS:rxc:COUNTER:120:0:U'         \
'DS:txc:COUNTER:120:0:U'         \
'DS:wrx:GAUGE:120:0:U'           \
'DS:wtx:GAUGE:120:0:U'           \
'DS:wrxc:COUNTER:120:0:U'        \
'DS:wtxc:COUNTER:120:0: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'

如何避免在RRDTool图形中出现空格？
