Cisco ACI - Atomic Counter

Hey Guys, 

 

We have Multi-Pod (stretched fabric) We recently had experienced packet drops between two endpoints which lead  huge impact at application level. Guess it is used per tenant basis, but We never used it... Running with certain queries and Just wanted to explore them out.

 

- How effective and accurate Atomic Counter feature is......In case of investigation at fabric level for packet drops or latency between endpoints or EPGs .

 

- Is this a GUI based feature only or We can also execute this on APIC CLI.  If yes, Could anyone share the CLI commands for same.

 

- Would there be any impact on performance or production services , If we applies Atomic counter on production setup or If in case Atomic counter has wrongly applied.

 

- Will this shows... At what point exactly latency or packet drop is and what is the cause behind the same. What need to be done.

 

- What all precautions we need to take before or while applying and using Atomic Counter.

Atomic Counters are sometimes useful for troubleshooting but make sure you have NTP Policy configured otherwise they wont work.
