[Q] - How to mask IPv6 on ingestion

[mark_forrester]

Hi Community

I'm trying to mask a IPv6 address on log ingestion but struggling to get the commad right

I find the IPv6 in the logs using the following command
// detect ip
| parse content, "LD IPADDR:ip LD"
| fieldsAdd ip = if(ipIsPublic(ip), ip, else: null)

However when trying to mask using a similar command I get the below error, can anyone advise the right command to mask a IPv6 detected string in a log entry.

USING(INOUT content)
| PARSE (content,"LD IPADDR:ip LD")
| FIELDS_ADD(content: REPLACE_PATTERN(content, ip,"*** DT MASKING ***"))

Hi,

Maybe, can you share some logs lines content where you want to extract that information?

Here is an edited sample content output in DT @DanielS your example fails on this example as no matches found.

Hello @mark_forrester using this regex in regex101 works perfect with all examples:

(?:[a-fA-F0-9]{1,4}:){7}[a-fA-F0-9]{1,4}

and also in Dynatrace:

let me know how it goes.
