We are pleased to announce the release of Ascent v2.10.4, which brings important performance optimizations, stability improvements, and functional enhancements across the platform.

Flow

Improvements

Ingestion Stability and Metric Accuracy

• Dedicated Ingest Routing: All ingest endpoints are now routed exclusively to ingest nodes to reduce latency, eliminate conflicts, and improve path separation.

• Shard Locking for Inserter: Replaced global locks with shard-level locks in the ingestion layer to prevent deadlocks and improve concurrency safety.

• Batch Size Metric Fix: Corrected the calculation of JSON batch sizes in metric outputs — metrics now represent per-batch payload size instead of total stream size.

• Rate Limiting Revamp: Introduced a configurable leaky-bucket algorithm for ingest rate limiting with burst handling and fine-grained limiter options.

• Fixed an issue where log entries associated with default_namespace were not visible in log explorer views.

Vault & Configuration Variables

Improvements

• Fixed a critical issue where Vault-stored variables failed to persist due to stale distributed cache states. The cache parameters have been tuned for distributed consistency.

Regex Validation (RE2)

• Regex validation improvements:

  • Server errors now shown in UI with contextual error messages.

  • Removed the 3-character minimum input constraint.

  • Added help link for RE2 syntax reference.

Bug Fixes

• Fixed issue where help documentation for rule-based code blocks failed to load in the UI.

• Removed redundant duplicated Pipelines & Rules tabs in the pipeline page.

Ascent Synthetics

Scenario Management

Improvements

• Resolved visual duplication issue in Scenario Management when editing existing scenarios.

Checks & Monitoring

Bug Fixes

• Resolved incorrect check behavior where frequency-based scheduled checks appeared as "manual" runs in the UI.

Observe

Dashboards & Visualization

Bug Fixes

• Fixed issue where some dashboards failed to import in preview mode due to serialization mismatches.

• Addressed failure of dashboard import from shared URL links.

Platform-Wide Improvements

License banner

• Updated ADF license banner with correct Apica email address.
