Hi Morty,

Apologies for the delay in getting back to you.

I investigated the solution a bit further.  LogViewPlus can parse this file with:

%d{MM-dd %H:mm:ss.fff} %3s{PID} %3s{TID} %p %c: %m%n

In this scenario, we are using format modifiers in an unusual way.  We are using them to skip forward and ignore the variable spacing.  This is a much cleaner solution than the development work proposed above.  It is also backwards compatible with earlier versions of LogViewPlus. 

We have also released LogViewPlus v2.5.53 as a BETA release.  The new release will treat the 'E' priority level as an error.  

Hope that helps,

Toby

Thanks for the update Morty. 

I appreciate the help you left for others - nice one!  I have applied some additional formatting to make that more clear.

The sample log entries are also really helpful.  Unfortunately, I am still not happy with how this file is being parsed as some log entries are not being parsed correctly with the pattern I provided above.  I can see that the logger column is sometimes missing and log entries are being joined together:

  

These files have a very strange format.  Sometimes a minimum length is used and sometimes it is not.  Format modifiers should probably not be used here because the format does not actually follow any minimum / maximum character rules.

LogViewPlus does not have a good solution for this at the moment.  I think what is needed is the ability to say that this field is required.  The problem with the empty spaces is that LogViewPlus thinks the field is missing.  If I have " %s " and the log entry contains just two spaces at this position, then the field I am looking for is missing.  In these logcat files, the field is not missing and we need to keep reading.

So I think we need the ability to tell the parser that this field will never be missing.  Just keep reading until you find it.  Maybe * would be a good way to indicate this?  Something like:

%d %*t %*s{Column1} %p %c: %m%n

It is not very pretty, but this is a real edge case.  I have never seen it before.  I will need to have a think about it and get back to you. 

Thanks,

Toby

for me is working great with your recommendation, thank you for that,
i dont need more support but in case you want to look further into this im adding a bigger piece of the log,
And for those who wonder how to get the android log live into a file here is the command i use in windows terminal:

adb logcat all > yourfile.txt

my device is connected to my pc with a usb and i had installed android studio (which installs adb),
and using logviewplus i open "yourfile.txt"

Log sample::

Hi Morty,

It looks like the Thread and String1 columns are left padded to be a minimum length of 5 characters.  I can get a good parse of the sample log entries provided with:

%d %5t %5s{Column1} %p %m%n

It looks like you could even add the logger with:

%d %5t %5s{Column1} %p %c: %m%n

Please see our documentation for more information on fixed length fields.

However, from your screenshot it looks like the log entries above these are also 4 characters long.  If you still have problems, it may help if you could provide some additional log entries.

You needed to add 'E' as a global log level because there is also an 'Emergency' level declared as fatal - so there is a conflict.  I will take a look to see if we can handle 'E' as a special case.

Hope that helps,

Toby

im using this
%d %t %s{Column1} %p %m%n
i had to add a global log level in configuration so the "E" gets recongnized as error.
and sometimes i get a bad parsing when there is only one space between the numbers (after the timestamp) as the next two lines show :
01-09 13:24:22.251  4826  4826 I SurfaceFlinger: SFWD update time=19495346470633
01-09 13:24:23.125 26402 26402 I SoundAlivePolicyManager: isGlobalEffectSupportCurrentAudioPath, currentDeviceType : 2

Thanks for the update Alex.  Glad to hear you got it working.

Were you able to find the underlying issue?  It would be good to know why LogViewPlus was having difficulty with this file.

Hi Toby,

Thanks for your checking and answer, finally I wrote one parser dll and resolved this problem

Have a nice day.

Hi Alex,

What version of LogViewPlus are you using?  Using v2.4.41, if I parse the file with the pattern you provided, I get a different result.


Which looks like the file was parsed correctly.  Maybe the parser is getting confused before the actual problem is visible?  In which case, I will not be able to reproduce the problem with the lines provided.

There appears to be a little bit of weirdness happening with the colon.  Sometimes it is proceeded with a space, and sometimes it isn't.  It does not appear to mark a place holder for an optional field.  This is a bit strange and might be part of the problem.   

Also, your pattern has "%t" twice.  This is saying you have two sets of data which both belong in the 'Thread' column.  This is not supported and the first set of data would be overwritten by the second.  

Putting this all together, I would recommend parsing the file with:
%d{MM-dd %H:mm:ss.fff} %s{Column1} %t %p %c: %m%n

This is very similar to the pattern you suggested, so I think the problem may be somewhere else.

Hope that helps,

Toby

Hi,

I'm trying to parse a logcat file, which is like below:

01-01 00:03:31.788 591 591 W SELinux : Multiple same specifications for qti.ims.ext.
06-16 12:49:15.390 734 1334 I abc : type=1400 audit(0.0:18414): avc: denied { read } for abc
06-16 12:49:15.390 734 734 I e : something here
06-16 12:49:15.403 1502 1668 I Engine: vs_get_temperature: read[0] skin-therm 33922 mC, weight[0] 553


I create one parse rule like below:
%d{MM-dd %H:mm:ss.fff} %t %t %p %c:%m%n

but the output is not correct, as below, output exist 3 problem:
1. line 2,3,4 mixed
2. subpid is missing.
3. the space between pid and subpid is not fixed value. It may be 2 or 3, depends on the length of subpid. I can't find one way to handle such case.


Could you please kindly help me here? 

Thanks!
