Gluesync 2.2.8: smart alerting, rebuilt OTA updates and rich technical metadata

Following our major security focus in version 2.2.7, we are proud to announce the official release of Gluesync 2.2.8. This update introduces a massive upgrade to our alerting, logging and monitoring ecosystem, making your data pipelines highly transparent, communicative and easier to govern.

From smart anomaly detection to complete overhauls of our update experience and global settings, Gluesync 2.2.8 turns background data replication into a fully observable, enterprise-grade operation.

Smart alert thresholds: pipeline anomaly detection

We heard you: a reliability tool shouldn’t just work quietly in the background; it needs to tell you exactly when something is wrong before it impacts your production environment. In version 2.2.8, we are introducing Smart Alert Thresholds to give infrastructure teams proper control over pipeline health.

Through the Core Hub, administrators can now configure specific anomaly detectors directly on entities, including:

  • Latency Thresholds: trigger alerts when replication delays exceed custom minute parameters.
  • Row Count Drift (developer preview): monitor data volume inconsistencies between sources and targets.
  • Stall Detection: identify stuck pipelines using advanced evaluation windows and customizable warmup periods to avoid false positives during initial synchronization.

A whole New Notifications Hub: Webhooks, SMTP and flood protection

To complement our new smart thresholds, the entire alerting architecture has been rewritten. Gluesync 2.2.8 introduces a centralized Notifications Hub designed to deliver the right alerts to the right channels, without nuking your inbox.

Advanced Webhook engine

Gluesync now supports native HTTP Webhook alerting designed around the CloudEvents spec v1.0. Infrastructure teams can securely stream alerts to external endpoints (like Slack, Microsoft Teams, or custom internal dashboards) featuring:

  • Severity filtering: dispatch notifications based on specific event levels (INFO, WARNING, CRITICAL).
  • Payload signing: secure your endpoints using SHA256 HMAC request signing headers (X-Gluesync-Signature).
  • Custom headers: inject corporate authentication or routing keys directly into the webhook payload.

Restructured SMTP & enriched emails

For teams relying on email alerts, we have shipped a proper, enterprise-grade SMTP client. Emails have received a complete visual redesign and are now fully burst-proof. Built-in notification flooding avoidance mechanisms ensure that unexpected notification write bursts are aggregated, preventing your mail server from being flooded during a pipeline crisis.

Granular UI controls & snoozing

Within the UI, entities now explicitly reflect their operational state, introducing a dedicated Error status visibility alongside the traditional “Healthy” green indicators. The new hub also gives engineers the ability to customize interruption methods or snooze notifications entirely during planned maintenance windows.

Rebuilt OTA update experience

We have completely re-engineered our Over-The-Air (OTA) update mechanism from the ground up to eliminate blind spots during platform maintenance. The new framework turns software updates into a transparent, step-by-step process.

When triggering an update, users are now presented with:

  • Crystal-clear progress tracking: real-time percentage and status indicators.
  • Component-level breakdown: granular visibility into exactly which module is being updated.
  • Itemized changelogs: direct access to release details for every single package before it installs.

Civilized global settings & UI polish

The Settings Tab has undergone a major spring cleaning to maximize usability and streamline governance.

  • Reorganized navigation: all platform configurations now live in one single, logical layout, leaving room for upcoming enterprise features.
  • Theme selector preview: users can now toggle between Light, Dark, or System mode (which automatically aligns Gluesync with your operating system’s visual preference).

Enriched Prometheus metrics

To support deep system observability, we have significantly enriched our native Prometheus /metrics endpoint. The tracking engine now exposes detailed data points fed by the same data sources used by our smart alert thresholds. This foundational update paves the way for deeper infrastructure inspection, with an overhauled, official Grafana dashboard template coming soon.

Rich technical metadata: audit trails delivered

One of our most requested enterprise features is finally live: Rich Technical Columns are now natively supported across our agent catalog. Every replicated record can now be enriched with metadata injected directly into the target schema (e.g., _gs_tx_id, _gs_op_type, etc.).

This native injection eliminates the need for writing complex User-Defined Functions (UDFs) or database triggers on your target layers, making data compliance, debugging and audit trails instantly accessible.
