{\em LNLS-UVX} combines ``beam trip'' and ``delayed beam delivery'' into ``no-beam'' events.  Such events occur when the beam current falls below the ``no beam'' threshold (60$\,$mA for the UVX multibunch operation), operation)  or when the beamline shutters are closed by a machine interlock flag during user time.   The scheduled  injection period is 30 minutes; beyond that  a ``no beam'' period which starts and  lasts until the interlock flags that prevent the beamline shutters from opening are cleared.  Early delivery is not considered for reliability purposes but is considered for   yearly beam availability, which is calculated based on the recorded events in the database. datalog.  ``Low-beam-current" events It  may happen after electrical power glitches or power supply faults.   Usually that by some reason  the current is completely partially  lost but a ``low-beam-current" situation may also happen,   for instance when a sextupole or a steering magnet power supply trips.   In these events the current and although it  is still above the ``no-beam'' threshold but it  is low compared to the expected current. for that time.  When this kind of event occurs the users are consulted about re-injections  and re-injection. If a new injection takes place  the problem is then  accounted for as a ``no-beam'' event. Otherwise just a "Fault" event is recorded.  {\em PETRA III} starts ``no-beam'' events (or ``downtime'') when the beam current

For those facilities where the limits are similar, the failure rates will allow a  meaningful comparison of the reliability of the injection process.
