[MuhamedSalihSeyedIbrahim]

We have implemented application insights NodeJS sdk for logging. But there are multiple tables and trace table level available,

1. we want to know purpose of all table and log level? and best practice in logging recommended by MS in azure appinsights?
   such as,
   availabilityResults
   browserTimings
   customEvents
   customMetrics
   dependencies
   exceptions
   pageViews
   performanceCounters
   requests
   traces - verbose , info , warn , error , critical

2. does it offer debug log? or is verbose level in track trace equivalent to debug logs?

3. is there a possibility to log custom format or custom tables or create tables in application insights?

4. application insights logging best practice recommended by MS AzMonitorCommunity needed?
