Sharepoint ULS multiline entries

Elastic Stack Logstash
1

Hi

I'm trying to configure Logstash to merge multiline messages into one, but I think this is a little different case than described on https://www.elastic.co/guide/en/logstash/current/multiline.html#_timestamps

SharePoint logs multilines by adding asterisk character after timestamp, duplicating all columns other than message and adding three-dots to the end of first part and at the beginning of second part.
Here are two lines of 1 log entry:

Do you have any idea how to merge second message with asterisk into previous one and get rid of three dots?

You can still use that example with the pattern "^%{mm/dd/yyyy hh:MM:ss.SS} " (two spaces at the end) because the second line does not have two spaces.

Then your (very long) line will look like:

You can use the gsub feature of the mutate filter to remove everything from the newline to the triple dots.

filter {
  mutate {
    gsub => [
      "message", "\\n.+\.\.\.", ""
    ]
  }
}

Hi guyboertje

Thanks for the reply. I've tried to use your pattern but it gave me an error "pattern %{mm/dd/yyyy hh:MM:ss.SS} not defined". So I replaced it with pattern => "^%{DATESTAMP} " (with one space) and now it merges log files with asterisk.

Is there any way to remove duplicated timestamp, process and columns other than message from merged entry to have one long message?

Actually you need to replace between the first ... <guid>\n to the second ...

filter {
  mutate {
    gsub => [
      "message", "\.{3}\s+\h{8}-\h{4}-\h{4}-\h{4}-\h{12}\n.+?\.{3}", ""
    ]
  }
}

guyboertje, your answer gave me a hint and here is my working solution

mutate {
    gsub => [
        "message", "\.{3}\s\w{8}-\w{4}-\w{4}-\w{4}-\w{12}", ""
    ]
	gsub => [
		"message", "\d{2}/\d{2}/\d{4}\s\d{2}:\d{2}:\d{2}.\d{2}\*.+?\.{3}", ""
	]
	gsub => [
		"message", "\.{3}", ""
	]
}

the first gsub removes ... {guid}\n (from logs in the middle)
the second gsub removes from the date with an asterisk to first three dots
the third gsub removes all other three dots occurrences

Now message is clear and fully concatenated

Thanks guyboertje, you are awesome! :slight_smile:
