Zoom Pool Capacity Planning

Zoom Pool License Cap Estimate

This dashboard estimates the Zoom licence cap required for pooled sessions to run without exhausting available rooms. It uses final scheduled pooled bookables plus the live allocator's 10-minute buffer, which makes the numbers directly relevant to capacity planning instead of raw slot grouping.

Capacity Recommendation

The current pool does not look capacity-bound on this week's final schedule. The system peak used 73.7% of the live pool, leaving 227 rooms free.

Recommendation A 733-room cap is the balanced planning target from this dataset. The current 864-room pool still sits 131 rooms above that.

Why The `pool_exhausted` Noise Matters Less Than It Looks

The noisy events are concentrated in a small number of B2G warmup windows, but the final concurrent schedule still stays below the live pool cap.

Read this carefully These spikes should not be treated as proof that raw licence count is too low. In this week, the final buffered schedule never exceeded 637 rooms, even though the pool had 864 available.

Data-backed Claim

This week's final buffered schedule required 637 rooms at most. The current pool has 864, so the system never came close to a raw licence ceiling.

What To Investigate Instead

  • B2G host-safe recovery and reassignment logic during warmup.
  • Why retained rooms still trigger `pool_exhausted` recovery attempts.
  • Whether some B2G sessions are over-concentrated into a few synchronized warmup windows.

Practical Decision

If you want a balanced operating cap based on this data alone, use 733. If you want a conservative cushion, 765 still stays below the current pool.
