When I start up the agent and look in the log, database connection is successful, but after about 5 minutes the following message is printed
com.quest.qsi.fason.db2.collection.utils.BalanceCalculator - Attempted calculating balance for metric DB2_CPU_Usage based on zero values
A review of the agent log finds additional similar messages for other collections:
com.quest.qsi.fason.db2.collection.utils.BalanceCalculator - Attempted calculating balance for metric Average_Logical_Reads based on zero values.
com.quest.qsi.fason.db2.collection.utils.BalanceCalculator - Attempted calculating balance for metric Average_Physical_Reads based on zero values.
These messages may occur for a variety of reasons and are internal to the system.
One example is when the agent temporarily loses its connection to the monitored instance due to it being down for backup.
