Empty /tmp/split-agent.log file

[zachschultz]

Hello, I'm running the Synchronizer with the following docker command:

docker run --rm --name split-synchronizer-proxy \
 -p 3000:3000 \
 -p 3010:3010 \
 -e SPLIT_SYNC_API_KEY="MY SPLIT API KEY HERE" \
 -e SPLIT_SYNC_PROXY="on" \
 -e SPLIT_SYNC_LOG_VERBOSE=true \
 -e SPLIT_SYNC_LOG_DEBUG=true \
 -e SPLIT_SYNC_LOG_STDOUT=true \
 -e SPLIT_SYNC_PROXY_SDK_APIKEYS="MY PROXY KEYS HERE" \
 splitsoftware/split-synchronizer

After successfully requesting a treatment from an app running the Split Java SDK client, I execd into the docker container running the Synchronizer and expected to see some logs in /tmp/split-agent.log file, however, the file was empty. Are there any other steps necessary to get more logging to happen?

Hello @zachschultz, I beleive that since you're using SPLIT_SYNC_LOG_STDOUT=true, the logs are being sent to the standard output (in this case, your containers') instead of the file. Since you enabled SPLIT_SYNC_LOG_DEBUG, you should be able to see full debug information by inspecting your containers output with docker logs <CONTAINER_ID>.

Please don't hesitate to let us know if this does not work as expected or you need further assistance. Regards, Martin.

Thanks for your quick response! So I am tailing the docker stdout as well now, but I'm still never getting any more logs than the intro:

Running in PROXY mode

Split Synchronizer - Version: 2.3.0 (e752118)
Log file: /logging.log
DB PATH: /tmp/splitio_1561147530007108000.db

With VERBOSE/DEBUG logging, should I expect to see each request from the Split Client in the docker logs?

@zachschultz Sorry I missed this in the previous answer, SPLIT_SYNC_LOG_VERBOSE, SPLIT_SYNC_LOG_DEBUG & SPLIT_SYNC_LOG_STDOUT are all enabled when assigned the value "on", as you've done with SPLIT_SYNC_PROXY

so doing:

docker run --rm --name split-synchronizer-proxy \
 -p 3000:3000 \
 -p 3010:3010 \
 -e SPLIT_SYNC_API_KEY="MY SPLIT API KEY HERE" \
 -e SPLIT_SYNC_PROXY="on" \
 -e SPLIT_SYNC_LOG_VERBOSE="on" \
 -e SPLIT_SYNC_LOG_DEBUG="on" \
 -e SPLIT_SYNC_LOG_STDOUT="on" \
 -e SPLIT_SYNC_PROXY_SDK_APIKEYS="MY PROXY KEYS HERE" \
 splitsoftware/split-synchronizer

Should behave as expected.

My apologies for this since I know it's confusing, we're currently working on improving it by supporting other true values as well and possibly notifying if an invalid value is found.

Thank you very much for reaching out. Regards,

Martin.
