HELP ticket metrics show that ~20% of the HELP tickets passed through the storage engines team have been related to eviction. We should do a thorough review of these help tickets to assess what statistics, logging, tools and methods were used to solves these tickets. From this assessment we should consider what elements of the help ticket could contribute to the HELP play book. We should also create separate tickets to improve WiredTiger based on the following questions:
Logging

• Did a log message cause confusion? 
• Were there any WiredTiger logs mentioned? If not, could we provide at least one message that is enabled by default that would provide insight without adding noise?
• Would it make sense to recommend increasing/decreasing the log level?

Statistics

• Did a statistic cause confusion? Was it misinterpreted or misleading?
• Was a statistic particularly helpful? This should be highlighted in the playbook
• Could a new statistic provide insight?
• Could we create an automated rule in the alexandria tool?
