Minimum Data defines how much valid performance data must have been logged
before the SLA alarm can be generated. This is intended to prevent spurious alarm
generation based on very small amounts of data.
For availability, the default setting is 24 hours, but in order to get a more rapid
response shorter periods are available.

An issue with SLA alarms is that performance data (especially for Availability) must
be averaged over a long time period and hence the alarms are relatively slow to
respond to short-term problems.
To address this, a separate 'Monitor' alarm system is supported, with a default
window size of 1 minute, and with configurable threshold values for the performance
parameters that are typically much high than the SLA equivalents. This means that
the monitor alarms are much better suited to detecting more severe but shorter-term
problems than marginal infringements of the SLA.
The Monitor alarm menu is shown below:
