One row per call-center cluster: the server whose database holds the live VICIdial tables, with its dialers under it. In call = agents talking (INCALL/QUEUE). Ready = waiting for a call (READY, or CLOSER for inbound). Calls waiting = customers on hold for an agent. Remote agents (extension R/…, e.g. TOR → Veritas PBX) are counted apart from people. Flags: no data for 10 min · calls waiting with nobody ready · auto-dial campaigns with an empty hopper while agents are ready · half or more of the agents paused · pauses over 30 min · frozen sessions · 20+ dead calls in an hour.
