NeverBlink for OpenSearch

OpenSearch-specific care for clusters your business runs on.

Default cloud monitoring shows you CPU and storage. NeverBlink shows you hot shards, unbalanced zones, slow query families and the configuration that caused them, with a fix and a senior OpenSearch engineer behind every alert.

Where OpenSearch clusters go wrong.

Hot nodes and hot shards

One node carries disproportionate traffic or storage, and the whole cluster slows to its pace.

Unbalanced availability zones

Primaries pile up in one AZ, so a single zone failure takes out more than it should.

Search queue saturation

Slowlogs blame innocent queries while thread pool rejections climb behind them.

Shard sprawl

Daily rollover leaves thousands of tiny shards that eat heap and slow recovery.

Snapshot gaps

Snapshot policies stopped running weeks ago, and nobody noticed.

Mapping explosions

Dynamic mappings add fields without limit until the cluster state becomes the bottleneck.

SHARD HEATMAPS

From hot node to guilty shard in two clicks

Heatmaps show shard distribution and load across nodes and zones. Drill from a hot node to the index, then to the shards behind the imbalance, and see whether it's an oversized shard, a hot primary or uneven allocation.

  • Availability zone awareness built in
  • kNN vector search and UltraWarm node views
  • Indices grouped by pattern, so rollover doesn't flood the view

DAILY HEALTH REPORTS

Know your cluster's state before standup

Scored checks across stability, performance, resiliency and security, including shard allocation, snapshot policies, heap pressure and version vulnerabilities. Delivered as reports and kept on a timeline.

Amazon OpenSearch Service

AWS keeps it running. NeverBlink keeps it healthy.

Connect with IAM or fine-grained access control. No changes to your domain and nothing installed on it.

IAM or FGAC

Authenticate with an IAM role or a fine-grained security user with read-only action groups.

Right-size instances

Cost recommendations based on real workload, including warm tiers and shard consolidation.

24/7 OpenSearch experts

Senior engineers who have run clusters at every scale, on call for the hard problems.

NeverBlink has proven itself to be far more than a monitoring tool. It's an end to end platform that gives us the stability, visibility, and support we need.
