##
#log.drop_mode_qlen = 3000

## The max allowed queue length before switching to flush mode.

## by receiving them in a loop without logging.
##
## Default: 8000

## Kill the log handler when it gets overloaded.
##

## few seconds.
##
## Default: on
##
#log.overload_kill = on

## The max allowed queue length before killing the log hanlder.

##
#log.overload_kill_qlen = 20000

## The max allowed memory size before killing the log hanlder.
##
## Log overload protection parameter. This is the maximum memory size
## that the handler process is allowed to use. If the handler grows
## larger than this, the process is terminated.
##
## Default: 30MB
##
#log.overload_kill_mem_size = 30MB

## Restart the log hanlder after some seconds.
##
## Log overload protection parameter. If the handler is terminated,
## it restarts automatically after a delay specified in seconds.
## The value "infinity" prevents restarts.
##
## Default: 5s
##
#log.overload_kill_restart_after = 5s

## Max burst count and time window for burst control.
##
## Log overload protection parameter. Large bursts of log events - many
## events received by the handler under a short period of time - can
## potentially cause problems. By specifying the maximum number of events
## to be handled within a certain time frame, the handler can avoid
## choking the log with massive amounts of printouts.
##
## This config controls the maximum number of events to handle within
## a time frame. After the limit is reached, successive events are
## dropped until the end of the time frame.
##
## Note that there would be no warning if any messages were
## dropped because of burst control.
##
## Comment this config out to disable the burst control feature.

## The Ephemeral Diffie-Helman key exchange is a very effective way of
## ensuring Forward Secrecy by exchanging a set of keys that never hit
## the wire. Since the DH key is effectively signed by the private key,

## are only a handful (since they are distributed with the OpenSSL
## package that has been built for the operating system it’s running on)
## and hence predictable (not to mention, 1024 bits only).
## In order to escape this situation, first we need to generate a fresh,
## strong DH group, store it in a file and then use the option above,
## to force our SSL application to use the new DH group. Fortunately,
## OpenSSL provides us with a tool to do that. Simply run:

## By default, EMQX web socket connection does not restrict connections to specific origins.
## It also, by default, does not enforce the presence of origin in request headers for WebSocket connections.
## Because of this, a malicious user could potentially hijack an existing web-socket connection to EMQX.

## To prevent this, users can set allowed origin headers in their ws connection to EMQX.
## WS configs are set in listener.ws.external.*
## WSS configs are set in listener.wss.external.*

## Example for WS connection
## To enables origin check in header for websocket connnection,
## set `listener.ws.external.check_origin_enable = true`. By default it is false,
## When it is set to true and no origin is present in the header of a ws connection request, the request fails.

## To allow origins to be absent in header in the websocket connection when check_origin_enable is true,
## set `listener.ws.external.allow_origin_absence = true`

## Enabling origin check implies there are specific valid origins allowed for ws connection.
## To set the list of allowed origins in header for websocket connection
## listener.ws.external.check_origins = http://localhost:18083(localhost dashboard url), http://yourapp.com`
## check_origins config allows a comma separated list of origins so you can specify as many origins are you want.
## With these configs, you can allow only connections from only authorized origins to your broker
