What does this PR do?
Add configuration value for
envoyCmd
.Motivation
We currently try to determine whether a PID represents an Envoy process using this constant path:
/proc/PID/bin/envoy
.We identified a situation where Envoy is being used by a symlink path that is different from this constant path.
For that reason, we have decided to use a configuration value for the Envoy path, which will allow us to update the searched path and include PIDs that are Envoy processes.
Additional Notes
I have created a follow-up task to implement path resolution and improve our current logic for identifying the Envoy process without needing a configuration value.
