OpManager's MSSQL database monitor
counters include Data Files size, Log files Used Percentage,
Active Transactions, Log growths, Log shrinks, Log files free
size, Log Cache hit ratio, etc.
Problems like increase in database size can be monitored by
the 'Data Files Size' monitor, which shows cumulative size of
all data files in the database including any automatic growth.
Monitoring this counter is useful to determine the correct size
of the databases. By proactively monitoring the databases and
configuring thresholds, probable database size bottlenecks can
be got ridden of.
