Getting Data In

how to configure splunk forwarder to monitor a file whose name changes on daily basis

Hi All,

I am trying to monitor a logfile which is generated in a path every day at 23:55 from a python script. My problem here is the file name of the log file changes everyday as the script is appending date to the file name.

Eg: Today the file name is "eswitch_16122019_235501_7000.log"
Tomorrow the file name will be "eswitch_17122019_235501_7000.log"

My inputs.conf is as below
[monitor:///opt/home/splunk_eswitch/eswitch_*.log]
disabled = false
index = test2
sourcetype = eswitch

Now when I run splunk list monitor I am seeing a below
/opt/home/splunk_eswitch/eswitch_*.log
/opt/delphi/splunk_eswitch/eswitch_16122019_235501_7000.log

My question is tomorrow does the forwarder sends the newly created file log to indexer with any issue as the yesterday's file will not be present in the same path.
Is there any better regex to have in inputs.conf then above one

Your inputs.conf looks good. The forwarder will notice the new file when it is created and will monitor it. Moving the old file to a new location should not affect the forwarder.
