rrdtool.OperationalError:无效的x-grid格式
如何解决此问题?这是错误:
rrdtool.OperationalError:无效的x网格格式
从:
X轴
[-x |--x-grid全球技术手册:商品及服务税:中期技术手册:中期技术手册:长期技术手册:长期技术手册:长期技术手册:长期技术手册:长期技术手册:长期技术手册:长期技术手册:长期技术手册:长期技术手册:长期技术手册
x轴标签的配置相当复杂。如果你没有足够的时间
特殊需求可能最好依靠自动配置来实现
把这个弄对。可以指定字符串“无”以抑制栅格
和标签
通过在TM中指定一定的时间量来定义网格
位置。您可以选择秒、分钟、小时、天、周、月
或者一年。然后,您定义其中有多少应该在每个
线条或标签。需要为底座指定这对(?TM:?ST)
网格(G??),主网格(M??)和标签(L??)。对于标签
您还必须定义LPR中的精度和strftime格式字符串
在LFM中。LPR定义每个标签的放置位置。如果是零,
标签将放置在相应行的正下方(有用
时间、日期等等)。如果在此处指定秒数
标签以该间隔为中心(适用于1月1日星期一)
等等)
如您所见,您的x-grid选项太短,因为您忽略了标签间隔:
“--x-grid”,“分钟:12:HOUR:1:0:%H”,
改为试试这个,每4小时贴一次标签:
“--x-grid”,“分钟:12:HOUR:1:HOUR:4:0:%H
当我尝试此方法时,它每4h标记一次:“--x-grid”,“分钟:12:HOUR:1:HOUR:4:0:%H”,然后我执行“python-graph.py”。它报告错误:回溯(最近一次调用):文件“graph.py”,第31行,“GPRINT:outbits:MIN:Out-traffic\:%6.21f%Sbps\\r“”)rrdtool.OperationalError:“平均流量:%6.21f%sbps”中的GPRINT格式错误。如何解决此问题?这是一个单独的错误,看起来您有%6.21f
,而您可能打算有%6.2lf
。正如错误所述,这是GRPRINT格式字符串中的错误。
