customMetrics problems about applicationinsights-node.js HOT 2 OPEN

@skhilliard Those first 6 warnings are performance counters. You can disable them via configuration options in Application Insights if you don't need them and want to remove the warnings. A fix will be applied to the Azure Monitor Exporter that will remove these warnings.

Your last metric "Redis Health Check" is invalid because of added spaces. This is another effect of moving to OpenTelemetry under the hood in 3.X and something I believe is worth updating in the migration guide. Thank you for your input there!

If you want fine grain control of how metrics are collected, I'd suggest following the migration guide above and moving to the Azure Monitor OpenTelemetry. Application Insights version 3.X is intended to be an easy upgrade path for those who have basic instrumentations with 2.X, while if you want more control and the advantages of OpenTelemetry, it's best to take advantage of the Azure Monitor OpenTelemetry.

@JacksonWeber Did you see my question regarding the metrics being "merged" into one value? E.g. instead of 4 Redis Health Check items with value of one, they are combined into one with a value of 4?
