Those sample events look like syslog with JSON message fields.  Since they're not pure JSON, the _json sourcetype won't work.  If you onboard the data using these props.conf settings

[ eset_syslog ]
CHARSET=UTF-8
LINE_BREAKER=([\r\n]+)
MAX_TIMESTAMP_LOOKAHEAD=32
NO_BINARY_CHECK=true
REPORT-syslog=syslog-extractions
SHOULD_LINEMERGE=false
TIME_FORMAT=%Y-%m-%dT%H:%M:%S.%3N%Z
TIME_PREFIX=\d\s
TRANSFORMS=syslog-host
TRUNCATE=10000
disabled=false

then this search will extract the fields.

index=foo sourcetype=eset_syslog | rex "(?<json>\{.*)" | spath input=json

@richgalloway  thanks for your swift response .. in the meantime , i changed the logs format from the server  to leef and and made extraction at index time rather than search time using propos.conf and transforms.conf

Did you miss .conf21 Virtual?

Good news! The event's keynotes and many of its breakout sessions are now available online, and still totally FREE!
