Well well well. After reading more documentation about splunk's scripted input, I've found out that Splunk can accommodate a continuously running script:
> If you want the script to run continuously, write the script to never exit and set it on a short interval. This helps to ensure that if there is a problem the script gets restarted. Splunk Enterprise keeps track of scripts it has spawned and will shut them down upon exit.
Hence my problem is elsewhere.
I did let the script run for half an hour, and I should have seen a handful amavis events in Splunk, but I've seen none. Running the script from command line successfully retrieved events from redis DB, so on script's side its all OK.
I'm going to try again and put truss in the mix to spy on the script.
