Metrics

Monitor add-in performance over time to find the ones slowing Office down

Overview

Deck's Core daemon periodically samples performance data for your add-ins so you can see which ones affect Office responsiveness, and how that changes over time.

What is measured

For each add-in, Deck tracks:

• Load time - how long the add-in takes to initialize when Office starts.
• Running state - whether the add-in is currently loaded and active.
• Resiliency - whether Office has flagged the add-in as slow or crashing (Office's own "disabled items" signal).

Samples are stored in the local database and kept for historical comparison, so the metrics view shows trends, not just a current snapshot.

Viewing metrics

Open the Add-ins page and click an add-in to open its detail view. The metrics chart plots its values over time, making it easy to spot an add-in that is getting progressively slower.

Polling interval

Metrics are collected in the background while the Core daemon runs. The default interval is 5 minutes; you can change it on the Settings page - unless your administrator has fixed it with the PollingInterval policy, in which case the control is locked and shows a managed by IT indicator. See Settings.

Metrics are only generated while Office applications are open and add-ins are loaded - an idle machine produces no new data points.

Using metrics for decisions

If an add-in consistently shows high load times:

• Disable it in the profiles where you don't need it - see Profiles.
• Check whether the publisher has released a performance update.
• Compare load times with and without the add-in by switching between profiles.

No data appearing?

If the metrics view is empty, see Metrics show no data.
