Subscription log cache hit percentage

Use this metric to track the percentage of log data read requests for the current subscription that are serviced from the log cache as opposed to being directly read from the DB2® logs. This statistic accrues over the life of the current run of the subscription.

Units: Percentage
Using: This metric provides an overall indication of the effectiveness of the log cache for this subscription.; A high log cache hit percentage is desirable since subscriptions do not need to incur the additional overhead of reading log data directly.; A low value could indicate that the cache is too small, or that the subscriptions is latent and not caught up to the cache.
