How to configure Neo4j logging settings in ThingWorx?

My ThingWorx server is growing Neo4j log files almost exponentially. In normal

installs

I can change configuration and control log retention, etc in neo4j.properties and cneo4j-wrapper.conf but neither appears to be available in ThingWorx installation.  Where is this configured?

Christopher, unfortunately the Neo4j log settings are not exposed in the platform. The only logging settings you can control per se, is the ThingWorx logging itself - Subsystems -> LoggingSubsystem has settings for max log size and retention time.

Ok. I went into Subsystems -> LoggingSubsystem and my install is configured max log size of 100000KB (100MB) according to Composer. This is the default.  Why then is my Neo logs growing to over 100GB in the ThingworxStorage/database/data directory??  How can I prevent Neo logs from generating 100's of GB of log files and overwhelming the storage on the server?

Christopher, that's the ThingWorx logs - if you go into ThingworxStorage\logs, 100mb would be the maximum size of a log file before it gets pushed into archive. Regarding the neo logs, those are the nioneo_logical logs, right? Do you have anything writing values into streams very frequently?

Yes. Data Tables and Streams. Both are stored in Neo. This is the basis of my original question.

Once I implemented platform-settings.json with PTC support's help; my logs started cleaning themselves up better.
