legacy linux MMA agent still sending data after Primary Key rotation
We have performed a primary / secondary key change for those servers not yet ready to move to AMA. we have noticed a few "onprem" linux syslog nodes still sending data even after the key was rotated...
I believe yes, the legacy Linux Microsoft Monitoring Agent (MMA) may continue transmitting telemetry after a workspace key rotation because it retains the previously cached authentication key and does not immediately revalidate against the newly issued key.
