Dcm — Opmanager
Arjun slumped in his chair, staring at the now-peaceful screen. DCM OpManager hadn't just shown him what was wrong. It had shown him what they were without it: blind.
Sixty seconds later, the phone stopped ringing. One by one, the red icons on the OpManager dashboard turned to calm, cool green. The silence returned to the NOC, but this time it was a healing silence.
