如何避免在我的RRDTool圖表中獲取空格？

Question

我創建了很多RRDTool圖表來監視Raspberry Pi服務器的各個方面。

我顯示36小時，10天，45天及18個月之類的東西傳送的數據，CPU溫度，平均負載等

然而，唯一的「連續」尋找圖分別是10天圖表中，所有其他人都有差距。我每隔一段時間記錄每個數據點。

有28（29）的圖像，所以我不打算把他們都在這裏，所以我把它們放在imgur for your perusal

但這裏是我談論的例子：

10天工作正常！

45天，沒有這麼多。

這裏是我的.rrd創建腳本：

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

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

rrdtool create load.rrd   \

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

rrdtool create mem.rrd   \

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

rrdtool create pitemp.rrd  \ 
--start N      \

我的整個抽獎腳本是像900線長，所以我就在這裏包括實際的抽獎代碼爲一組圖形（$RRDTOOL是一個包含路徑/usr/bin/rrdtool一個變量）：

是的，我知道，標題上的一個圖表是錯誤的，我已經解決了這個問題，但只有在將所有圖像保存爲imgur後。

如果您選擇60秒內的--step，我會選擇120秒的mrhb，而不是60秒，因爲rrdtool會忽略超過60秒的任何更新。

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'  \
