Field cases

Troubleshooting and operational automation from real environments.

01Citrix · PVS

PVS targets register only after a user signs in

ABOUT THIS LAB

Experience is most useful when it can be reused.

SMR Lab is Smrutimaya Mohanty's public engineering notebook: a curated, anonymised record of production incidents, practical fixes and systems built from real requirements. The aim is simple—preserve the details that are easy to forget and share the ones that may help another engineer.
