Tessera records every sync attempt across every source. Per-source history is one click away; cross-source activity is its own view.
01
Before you start
Tier
01
Connectors and their sync monitoring are an Enterprise feature.
02
Step 1: Per-source history
In the Data Sources view, open the history panel on any source. It shows the recent sync attempts with each one's timestamp, rows imported, duration, the new cursor value, and the error message if it failed.
03
Step 2: Cross-source feed
The sync-activity view collects every sync from every source, newest first, in one place. Filter by source or by status to focus on failures. A summary strip shows totals — how many syncs ran, how many failed, how many rows came in, across how many sources — for a "how is the fleet doing today" glance.
Filter by source or by status to focus on failures.
04
Step 3: Feed it into your monitoring stack
Tessera emits standards-based metrics in Prometheus and OpenTelemetry formats, so the same signals flow into Grafana, Datadog, Honeycomb, or any OTLP backend — no lock-in. Alert on repeated failures or unexpected zero-row syncs there.
05
What the history captures
Timestamp of the sync attempt.
Rows imported (zero if nothing new, or on failure).
How long the attempt took.
Error message on failure; none on success.
New cursor value, for incremental syncs.
06
What the history captures — how much is kept
The panel keeps the most recent attempts per source; older ones roll off.
Key Takeaways
01
Opened a source's history panel to see each attempt's timestamp, rows imported, duration, cursor value and any error.
02
Used the cross-source sync-activity view, filtered by source or status, with its summary strip of totals.
03
Sent the same signals to your monitoring stack as Prometheus and OpenTelemetry metrics.
