Use the new information to improve HADR monitoring. Several
new columns were added to the MON_GET_HADR table function and the
information returned by the -hadr parameter of the db2pd command.
You can use the following new columns to monitor the health of
your HADR databases:
- STANDBY_SPOOL_PERCENT lets you know how much of your HADR log
spooling space is being used.
- HADR_FLAGS contains a subset of fields that indicate when assisted
remote catchup is occurring or if there are issues with log receipt
or retrieval on the standby.

problems affecting your HADR deployment, the following columns were
also added to the MON_GET_HADR table function and the information
returned by the
db2pd command:
- HEARTBEAT_MISSED and HEARTBEAT_EXPECTED allow you to determine
whether the accumulated number of missed heartbeats is a cause for
concern.
- STANDBY_ERROR_TIME indicates the last time the standby had a major
error.
