transforms.conf not working

prashant_kumar_ — Mon, 24 Jan 2022 13:04:16 GMT

I have events like this comin from Heavy forwarder

"geo": {"continent": "NA", "country": "UK", "city": "LONDON"}, "hostname": "xxxx xxx xxxx"

I have to override the host metadata with the hostname field from the event.

my transforms.conf

[hostoverride]
SOURCE_KEY = hostname
REGEX = (.*)
DEST_KEY = MetaData:Host
FORMAT = host::$1

props.conf
[sourcetypename]
.
.
.
TRANSFORMS-hostoverride = hostoverride

In some of the events I am still getting the Heavy forwarder name.
Thanks for the help in Advance

@prashant_kumar_ use this transforms

[hostoverride]
REGEX = hostname\"\:\"(.*)\"
DEST_KEY = MetaData:Host
FORMAT = host::$1

props.conf

[override]
TRANSFORMS-ooo = hostoverride
INDEXED_EXTRACTIONS = json
DATETIME_CONFIG = CURRENT
LINE_BREAKER = ([\r\n]+)
NO_BINARY_CHECK = true
disabled = false
pulldown_type = true

my test file

{"geo":"NA","city":"UK","country":"London","hostname":"lp5cd8213yt4"}

Regex was right, due to the size of data the hostname at the end of the events greater than 4096 character were missed and HF name was showing up.
changes I made in transforms.conf:
[hostoverride]
REGEX = hostname\"\:\s\"(.*)\"
DEST_KEY = MetaData:Host
FORMAT = host::$1

LOOKAHEAD = 10000

and it worked!!!
