Feature

Smart Anomaly Detection

Introducing AI-powered anomaly detection that learns your infrastructure's normal behavior and surfaces real issues — not noise. Set custom sensitivity thresholds per service and get alerts where your team already works.

  • ML-driven baseline learning with automatic seasonal adjustment
  • Custom anomaly sensitivity thresholds per metric, service, or team
  • Native Slack and Microsoft Teams integration for alert routing
  • Anomaly correlation — groups related anomalies into a single incident
// Configure anomaly detection via API const detector = await signalis.anomaly.create({ metric: "request_latency_p99", sensitivity: 0.85, baseline_window: "7d", notify: ["#ops-alerts"] });

Improvement

Performance Improvements

Across-the-board performance gains focused on dashboard rendering speed and backend query efficiency. Large dashboards with 50+ widgets now load significantly faster.

  • 40% faster dashboard loads through virtualized widget rendering
  • Reduced memory usage by 28% on metric aggregation workers
  • Query planner improvements — complex PromQL queries now 3x faster
  • WebSocket connection pooling reduces reconnect overhead by 60%

Fix

Bug Fixes

Addresses several edge-case bugs reported by customers running multi-region deployments with non-UTC timezone configurations.

  • Fixed timezone offset calculation in alert scheduling across DST boundaries
  • Corrected metric aggregation edge case where counter resets produced negative deltas
  • Resolved intermittent 503 errors during rolling cluster upgrades

Feature

Custom Dashboards

Design the observability view your team actually needs. Drag, drop, resize — with 20+ widget types from heatmaps to log tails, your dashboards are now fully yours.

  • Drag-and-drop dashboard builder with snap-to-grid layout
  • 20+ widget types: time-series, heatmaps, tables, log streams, status grids, and more
  • Share dashboards via link, embed in Notion, or export as PDF
  • Dashboard variables with dropdown selectors for dynamic filtering
  • Auto-refresh intervals configurable per-dashboard (5s to 24h)
January 8, 2026 v3.0.1
Fix

Hotfix Release

Critical fixes following the Kalleo 3.0 launch, addressing SSO authentication edge cases and API stability under high concurrency.

  • Fixed SSO redirect loop when IdP metadata contained expired certificates
  • Patched API rate limiting — burst allowance was not resetting after window expiry
  • Resolved WebSocket connection drops during high-throughput metric ingestion

Feature Breaking

Kalleo 3.0 — The Platform Release

A ground-up redesign of the query engine, a modernized UI built for speed, and API v3 with full OpenTelemetry-native support. This is the biggest release in Kalleo history.

  • New columnar query engine — 10x faster on high-cardinality queries
  • Completely redesigned UI with keyboard-first navigation and command palette (Cmd+K)
  • API v3 with OpenTelemetry-native data model and gRPC support
  • Unified search across logs, metrics, and traces in a single query bar
  • Role-based access control (RBAC) with granular per-dashboard permissions
  • Dark mode is now the default — light mode available in settings
Breaking: API v2 is deprecated and will be removed on June 1, 2026. Migration guide available at docs.signalis.io/migrate-v3. The legacy query syntax is supported in compatibility mode — enable via --compat-v2 flag.
November 14, 2025 v2.9.0
Feature

Infrastructure Maps

See your entire infrastructure topology at a glance. Auto-discovered maps show service dependencies, health status, and traffic flow in real time — no manual configuration required.

  • Auto-discovered topology maps from trace data and network metadata
  • Real-time dependency visualization with traffic volume and error rate overlays
  • Click any node to drill into service-specific metrics, logs, and traces
  • Export maps as SVG for architecture documentation
October 28, 2025 v2.8.5
Improvement Fix

Stability Release

Focused on data reliability and export quality. Improved long-term data retention policies and resolved several issues in the CSV/JSON export pipeline.

  • Improved data retention engine — configurable per-metric retention from 15 days to 2 years
  • Fixed CSV export truncation on datasets exceeding 100K rows
  • JSON export now includes full metadata headers and query parameters
  • Reduced ingestion pipeline latency by 18% through batch write optimization
  • Fixed alert deduplication logic that occasionally suppressed valid re-fires
