Hi
on logstash need to override timestamp, here is the scenario input file, output as http.
here is the string must be send via “http output”:
mymeasure,tag=mytag field="myfield" 1689682934
FYI: this part "1689682934" is timestamp.
now question is how can i extract date from filename, and time from log line and create epoch time format like 1689682934 and put in end of line.
here is file name:
/tmp/log.cus.20230720
here is log line:
00:00:13.441 cus module: A[srv1]B[551]C[000]
expected timestamp
20230720 00:00:13.441
expected timestamp in epochtime format
1689682934
Any idea?
Thanks
