@zhugw Can you confirm your specific versions of mloginfo
and MongoDB server? Can you also include some additional log lines?
With mloginfo --queries
(v1.5.1) I get output for your sample log line:
namespace
operation pattern count min (ms) max (ms) mean (ms) 95%-ile (ms) sum (ms)
()
foo.bar update {"guid": 1} 1 186 186 186 186.0 186
@stennie
$ mloginfo --version
mtools version 1.3.2
$ mongo 127.0.0.1:27017
MongoDB shell version: 3.2.17
additional log lines

Does there are some special character(e.g.\n
) in text field affect mloginfo ? e.g. actually the text field in mongodb
"text" : "\n\n\n格林格抽油烟机相比其它牌子还是挺不错的。我家里用的那款格林格抽油烟机就是当年我买的,真正免清洗的功能,到现在应该也用了3年左右了吧,基本上没有什么大毛病,价格挺实惠",

@zhugw Log lines with embedded newlines (\n
) aren't well handled as at mtools 1.5.1 so your mloginfo --queries
output is unfortunate but expected. This is the same issue as #416, but we haven't had anyone keen to address it yet.
Log lines with embedded \n
will be treated as multiple log lines but only the first line (which includes the leading timestamp) will match for extracting log details.
There are some assumptions about line-based parsing and matching in the current code that make this more involved than a quick fix, but if you are interested in fixing a PR would be welcome.
I'm going to close this as a dupe of #416.

@stennie Today I cloned the code and tried to debug the mloginfo.py
tried to find where to parse the raw log file. But very frustrating, I even cannot start mloginfo.py
it successfully . When I run it I got below error:
this tool can't parse input from stdin.
So how could run it successfully in pycharm
?
Although I could run nosetests on test_mloginfo
in terminal
nosetests --tests=test_mloginfo
but in this case I cannot debug it
After executing
mloginfo mongo.log --queries
a little confused with some resultswhy some count of update records could be 0 and the other statistics item is
-
?In mongo.log the detail like this
