Hello! As far as my understanding goes, I see that eviction works ok.
>2019-09-09 11:04:03.557 WARN [sys-stripe-5-#6%TemenosGrid%] >IgniteCacheDatabaseSharedManager - Page-based evictions started. Consider >increasing 'maxSize' on Data Region configuration: 1G_Region This message tells that now eviction process is started and will free pages according to the algorithm. it means that when Ignite requests for a new page and there are no available ones, then Ignite will apply eviction first and then use those pages for a new values. So you will not see any significant memory changes during eviction. I.e. Ignite will show that the data region is full, but still allows you to write new values. There are no any special messages log messages regarding evicted pages. Only the first one, when eviction comes to the play. I think you may try to look into getEvictionRate() metrics [1] for details. Also you should be able to see it in Visor GUI.

Log attached, as well...after the log of the below... 2019-09-09 11:04:03.557 WARN [sys-stripe-5-#6%TemenosGrid%] IgniteCacheDatabaseSharedManager - Page-based evictions started. Consider increasing 'maxSize' on Data Region configuration: 1G_Region after a few minutes you see memory steadily decrease. What information in the log will help me determine how many pages are freed, etc?
