looks like this function is never used...

[stcheng]

could you update this pull request to compare it with the current master?

Could we have more document/comment on the meaning and usage of those sample files?

Hi Taoyu,
The usage of files is described in https://github.com/Azure/SONiC/wiki/LogAnalyzer#analysis-of-log-messages

I was talking about the log files in samples/sample1 folder. Shall we modify the sample string and runID there to be more meaningful? I'm feeling current sample difficult to follow

Hi Taoyu,
Following the description in the wiki page it should be clear I think, but if you'd like to suggest different content, you can send through mail and I can add it.

Hi Hrachyam,

What I mean is that we might be able to do some modification in the details to make the sample easier to read. Such as

• In command_line.txt, modify the file paths to relative path in repo instead of /home/hrachya/projects/… so that user knows that those files can be found in the repo
• Rename command_line.txt to README.txt or other obvious name so readers know this is the first file they need to read
• Rename runID to something meaningful instead of myTest116
• Write some descriptive message in ignore string sample instead of random strings like “67hello8"

i removed the sample directory, added sample to https://github.com/Azure/SONiC/wiki/LogAnalyzer. I'm also going to open new pull request for ansible files invoking loganalyzer which should help understanding its usage better.
