On the http route settings page in Notehub, `_health_host.qo` is listed as a system notefile.

I don’t recall seeing that before. I checked the [docs](https://dev.blues.io/api-reference/system-notefiles) but didn’t see it mentioned.

Taking an (allegedly!) educated guess, I imagine that queue is used for `hub.log` requests to separate them from Notecard’s own health logs? Kind of makes sense, given the distinction between platform and paid events.

Hi @devElert,

You’re exactly right - `_health_host.qo` is used for `hub.log` requests to separate user-generated events from platform-generated events (we just haven’t updated the docs yet!).

Thanks,  
Rob

I can see three types log .qo files, may I know the difference between \_health\_host.qo and \_log.qo, use cases?.

Is there any option to drop application debug logs in notehub?

Hi @Srihari,

These Notefiles are documented here: [System Notefiles - Blues Developers](https://dev.blues.io/api-reference/system-notefiles/)

Thanks,
