Python rrdtool.OperationalError:无效的x网格格式
提问于 2018-07-09 17:52:32
graph.py的代码是：
# -*- coding: utf-8 -*-
#!/usr/bin/python
import rrdtool
import time定义图表上方的标题
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,

"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(最近一次调用)：
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
我怎样才能解决这个问题呢？

这是错误：
rrdtool.OperationalError: invalid x-grid format
X轴
-x|--x-grid GTM:GST:MTM:MST:LTM:LST:LPR:LFM
X轴标签的配置相当复杂。如果您没有非常特殊的需求，最好是依靠自动配置来实现这一点。可以指定字符串none以同时禁止显示栅格和标签。
网格是通过在TM位置指定一定的时间来定义的。您可以选择秒、分钟、小时、日、周、月或年。然后，您可以定义每行或标签之间应该传递多少个这样的值。需要为基础网格(G??)、主网格(M??)指定此对(?TM:?ST)。和标签(L??)。对于标签，还必须在LPR中定义精度，在LFM中定义strftime格式字符串。LPR定义了每个标签的放置位置。如果它是零，标签将被放置在相应的行的正下方(适用于小时、日期等)。如果您在此处指定秒数，标签将以此间隔为中心(适用于星期一、一月等)。
如您所见，您的x-grid选项太短，因为您省略了标签间隔：
"--x-grid", "MINUTE:12:HOUR:1:0:%H",
试试这个，它每隔4小时标记一次：
"--x-grid", "MINUTE:12:HOUR:1:HOUR:4:0:%H
