Metrics show no data

Symptoms

Metrics charts show "No data" for all add-ins.
Only some add-ins have metrics data.
Metrics data stops appearing after an update.

Solutions

Wait for data collection

Metrics are collected periodically by the Core daemon. After a fresh install or a database reset, it can take one or more polling intervals for the first data points to appear. The default interval is 5 minutes (or whatever the PollingInterval policy sets).

Verify the Core daemon is running

The daemon (Vediram.Deck.Core) must be running to collect metrics. Its tray icon is the quick check - if it's missing, the daemon isn't running.

Get-Process Vediram.Deck.Core -ErrorAction SilentlyContinue

Relaunch Deck from the Start menu (which starts the daemon), or start it directly:

# Per-user install:
& "$env:LOCALAPPDATA\Programs\Vediram\Deck\Vediram.Deck.Core.exe"
# Per-machine install:
& "$env:ProgramFiles\Vediram\Deck\Vediram.Deck.Core.exe"

Check that Office is running

Metrics are only generated while Office applications are open and add-ins are loaded. With no Office apps running, no new data points are produced.

Check the daemon log

Select-String -Path "$env:LOCALAPPDATA\Vediram\Deck\core.log" -Pattern "metrics"

Clear and rebuild

If metrics data is corrupt, reset the database and let Deck rebuild it:

# Stop Deck first, then:
Remove-Item "$env:LOCALAPPDATA\Vediram\Deck\deck.db"

Restart Deck. Note this also clears profiles and crash history.
