I am currently getting this error:

Failed: cannot extract value from json by path "$.wiredTiger.cache['maximum page size at eviction']": no data matches the specified path

After some debugging i figured, that in MongoDB 6.3 (this commit: https://github.com/mongodb/mongo/commit/838d3648a66bc46f10e6fcad9d0294df5331d090) the wording changed from `maximum page size at eviction` to `maximum page size seen at eviction`.

The plugin should be updated to handle the new property name.
