## Maximum size of the crash log in bytes, before it is rotated
##
## Default: 10MB
##
## Acceptable values:
## - a byte size with units, e.g. 10GB
log.crash.size = 10MB
## The schedule on which to rotate the crash log. For more
## information see:

##
## Default: $D0
##
## Acceptable values:
## - text
log.crash.rotation = $D0
## The number of rotated crash logs to keep. When set to
## 'current', only the current open log file is kept.
##
## Default: 5
##
## Acceptable values:
## - an integer
## - the text "current"
log.crash.rotation.keep = 5
## Name of the Erlang node
##
## Default: VerneMQ@127.0.0.1
##
## Acceptable values:
## - text
nodename = VerneMQ@127.0.0.1
## Cookie for distributed node communication. All nodes in the
## same cluster should use the same cookie or they will not be able to
## communicate.
## IMPORTANT!!! SET the cookie to a private value! DO NOT LEAVE AT DEFAULT!
##
## Default: vmq
##
## Acceptable values:
## - text
distributed_cookie = vmq
## Sets the number of threads in async thread pool, valid range
## is 0-1024. If thread support is available, the default is 64.
## More information at: http://erlang.org/doc/man/erl.html
##
## Default: 64
##
## Acceptable values:
## - an integer
erlang.async_threads = 64
## The number of concurrent ports/sockets
## Valid range is 1024-134217727
##
## Default: 262144
##
## Acceptable values:
## - an integer
erlang.max_ports = 262144
## Set scheduler forced wakeup interval. All run queues will be
## scanned each Interval milliseconds. While there are sleeping
## schedulers in the system, one scheduler will be woken for each
## non-empty run queue found. An Interval of zero disables this
## feature, which also is the default.
## This feature is a workaround for lengthy executing native code, and
## native code that do not bump reductions properly.
## More information: http://www.erlang.org/doc/man/erl.html#+sfwi
##
## Acceptable values:
## - an integer
## erlang.schedulers.force_wakeup_interval = 500
## Enable or disable scheduler compaction of load. By default
## scheduler compaction of load is enabled. When enabled, load
## balancing will strive for a load distribution which causes as many
## scheduler threads as possible to be fully loaded (i.e., not run out
## of work). This is accomplished by migrating load (e.g. runnable
## processes) into a smaller set of schedulers when schedulers
## frequently run out of work. When disabled, the frequency with which
## schedulers run out of work will not be taken into account by the
## load balancing logic.
## More information: http://www.erlang.org/doc/man/erl.html#+scl
##
## Acceptable values:
## - one of: true, false
## erlang.schedulers.compaction_of_load = false
## Enable or disable scheduler utilization balancing of load. By
## default scheduler utilization balancing is disabled and instead
## scheduler compaction of load is enabled which will strive for a
## load distribution which causes as many scheduler threads as
## possible to be fully loaded (i.e., not run out of work). When
## scheduler utilization balancing is enabled the system will instead
## try to balance scheduler utilization between schedulers. That is,
## strive for equal scheduler utilization on all schedulers.
## More information: http://www.erlang.org/doc/man/erl.html#+sub
##
## Acceptable values:
## - one of: true, false
## erlang.schedulers.utilization_balancing = true
## This parameter defines the percentage of total server memory
## to assign to LevelDB. LevelDB will dynamically adjust its internal
## cache sizes to stay within this size. The memory size can
## alternately be assigned as a byte count via leveldb.maximum_memory
## instead.
##
## Default: 70
##
## Acceptable values:
## - an integer
leveldb.maximum_memory.percent = 70
