Question

graph.py的代码是：

# -*- coding: utf-8 -*-
#!/usr/bin/python
import rrdtool
import time

＃在图表上方定义标题

title="Server network traffic flow ("+time.strftime('%Y-%m-%d',time.localtime(time.time()))+")"

＃生成Flow.png文件

rrdtool.graph("Flow.png", "--start", "-1d", "--vertical-label=Bytes/s",\
"--x-grid", "MINUTE:12:HOUR:1:0:%H",\
"--width", "650", "--height", "230", "--title", title,
"DEF:inoctets=Flow.rrd:eth0_in:AVERAGE",      #Specify the NIC inflow data source DS and CF 
"DEF:outoctets=Flow.rrd:eth0_out:AVERAGE",    #Specify the network card outgoing traffic data source DS and CF
"CDEF:total=inoctets,outoctets,+",            #Combine the incoming and outgoing traffic through the CDEF to get the total traffic total

"LINE1:total#FF8833:Total traffic",           #Draw total flow in lines
"AREA:inoctets#00FF00:In traffic",            #Draw inflow in area
"LINE1:outoctets#0000FF:Out traffic",         #Draw outflow in lines

"CDEF:inbits=inoctets,8,*",                   #Convert incoming traffic to bit, ie *8, calculate the result to inbits
"CDEF:outbits=outoctets,8,*",                 #Convert the outgoing traffic to bit, ie *8, and calculate the result to outbits
"COMMENT:\\r",                                #Output a line break below the grid
"COMMENT:\\r",
"GPRINT:inbits:AVERAGE:Avg In traffic\: %6.21f %Sbps",  #Draw inflow average
"COMMENT:   ",
"GPRINT:inbits:MAX:Max In traffic\: %6.21f %Sbps",      #Draw inflow maximum
"COMMENT:   ",
"GPRINT:inbits:MIN:MIN In traffic\: %6.21f %Sbps\\r",   #Draw inflow minimum

"COMMENT:   ",
"GPRINT:outbits:MIN:MIN Out traffic\: %6.21f %Sbps\\r")  #Draw outflow minimum

当我执行“ python graph.py”时

错误报告：

回溯（最近通话最近一次）：

文件“ graph.py”，第31行，位于

"GPRINT:outbits:MIN:MIN Out traffic\: %6.21f %Sbps\\r")

rrdtool.OperationalError：无效的X网格格式

我该如何解决这个问题？

Answer 1

这是错误：

rrdtool.OperationalError: invalid x-grid format

来自RRDTool Manual：

X轴

[-x | --x网格GTM：GST：MTM：MST：LTM：LST：LPR：LFM]

x轴标签的配置非常复杂。如果你没有   特殊需求可能最好依靠自动配置   得到这个权利。您可以指定字符串none抑制网格   和标签。

通过在？TM中指定一定的时间来定义网格   职位。您可以选择第二，分钟，小时，天，周，月   或YEAR。然后定义每个之间应通过多少个   线或标签。需要为基数指定这对（？TM：？ST）   网格（G25），主网格（M25）和标签（L25）。对于标签   您还必须定义LPR的精度和strftime格式的字符串   在LFM中。 LPR定义每个标签的放置位置。如果是零   标签将被放置在相应行的正下方（有用   时间，日期等）。如果您在此处指定秒数   标签以该间隔为中心（对一月星期一有效）   等）。

如您所见，您的x网格选项太短，因为您省略了标签间隔：

"--x-grid", "MINUTE:12:HOUR:1:0:%H",

请尝试此操作，它每4小时贴一次标签：

"--x-grid", "MINUTE:12:HOUR:1:HOUR:4:0:%H
