Ingesting JSON Data Samples w/ Logstash

It is finding no files that match the value of @path. Could be a permissions issue.

Also @file_completed_log_path should be a file, not a directory.

Badger please don't be upset with me, but it was a misspelling of the file name. :man_facepalming:

Do you know how I can fix this?

JSON parse error, original data now in message field {:error=>#<LogStash::Json::ParserError: Unexpected character (',' (code 44)): Expected space separating root-level values

Look at the [message] field. Is it valid JSON?

There are @message within the JSON, but they aren't necessarily used as a field. It's apart of the string in the field.

What is in the [message] field?

When I grep for it this is what I find and I see the comma that the error points out.

cat train_features_0.json | grep '"message"'

Good news, is that I only found one occurrence.

No, I meant on stdout. But what you posted there indicates the problem. A json codec does not keep accumulating lines until it has a complete JSON object, it parses each line as an object. What you need is a multiline code to combine all the lines for one object into a single event, then parse it using a json filter.

If you want to ingest the whole file as one event see Merge Multiline json into single line json using codec multiline plugin - #2 by Badger. If a file contains multiple objects then this might work.

I was able to finally get data in, but now I'm having issues with my license and elasticsearch can't be reached.

Whenever I make some progress, I get stumped.

I suggest you ask a new question. This one has covered way too many issues.
