Background:
- As a wt code beginner, enable all verbos config can help us to study the WT code, bug there are too much verbos configes.
- sometimes, when we need to analyze the cluster jitter problem, we should open all the module verbos by using WT_VERBOSE_INFO or WT_VERBOSE_DEBUG level. if we have a config_all_verbos config ,we can use the following command:
db.adminCommand({setParameter:1, wiredTigerEngineRuntimeConfig:'verbose=[config_all_verbos=1]'})
- If there is no all global verbos configuration, dump all module's log(for exaple, all WT_VERBOSE_INFO level's log) is Very troublesome.
