I am attempting to use a gsub mutate to remove words that are less than 4 characters in length.
mutate { gsub => [ "[tag][cloud][chat]", "(\S+){1,3}", "" ] }
But it is removing everything. Any suggestions?
I am also attempting to remove URLs but that doesn't seem to be working either.
mutate { gsub => [ "[tag][cloud][chat]", "(http:\S+)", "" ] }
mutate { gsub => [ "[tag][cloud][chat]", "(https:\S+)", "" ] }But these two gsubs ARE working.
mutate { gsub => [ "[tag][cloud][chat]", "(\[emote=\S+\])", "" ] }
mutate { gsub => [ "[tag][cloud][chat]", "(@\S+)", "" ] }If you have a word of seven characters in that field then I would expect that pattern to remove 3, then to remove 3 again, and then to remove 1. Which would remove the entire word. You need to anchor the patterns.
Perhaps "(^|\b)\S{1,3}(\b|$)" ?...
That worked for the words less than 4 characters.
Thank you!!!
Do you have a suggestion for removing any URLs?? Nothing seems to work for me, at this point. I was trying to cover http and https but I am going to need to make sure I cover ftp as well.
I suggest you look at the grok patterns for URLs and maybe extract parts of those. A complete URL would be

I actually have it working now
