This is *NOT* a RST file but the syntax has been chosen so
that it may become an RST file at some later date.
.. varnish_vsc_begin:: lck
:oneliner: Lock Counters
:order: 70
Counters which track the activity in the different classes
of mutex-locks.
The counts may be slightly wrong if there are more than one
lock instantiated in each class (ie: .creat > 1)
.. varnish_vsc:: creat
:type: counter
:level: debug
:oneliner: Created locks
.. varnish_vsc:: destroy
:type: counter
:level: debug
:oneliner: Destroyed locks
.. varnish_vsc:: locks
:type: counter
:level: debug
:oneliner: Lock Operations
.. varnish_vsc:: dbg_busy
:type: counter
:level: debug
:oneliner: Contended lock operations
If the ``lck`` debug bit is set: Lock operations which
returned EBUSY on the first locking attempt.
If the ``lck`` debug bit is unset, this counter will never be
incremented even if lock operations are contended.
.. varnish_vsc:: dbg_try_fail
:type: counter
:level: debug
:oneliner: Contended trylock operations
If the ``lck`` debug bit is set: Trylock operations which
returned EBUSY.
If the ``lck`` debug bit is unset, this counter will never be
incremented even if lock operations are contended.
