Why monitor Elasticsearch?

Elasticsearch powers search, logging, and analytics for thousands of organizations worldwide. Monitoring Elasticsearch is critical to maintain cluster health, optimize indexing throughput, track search latency, and prevent JVM heap exhaustion. Xitoring's Elasticsearch integration provides deep visibility into every aspect of your cluster.

Metrics

What we monitor

Cluster Health

Overall cluster status (green/yellow/red) and active shard count.

JVM Heap Usage

Heap used, committed, and max across all nodes with GC stats.

Indexing Rate

Documents indexed per second across the cluster.

Search Rate

Search queries per second and average search latency.

Shard Count

Active, relocating, initializing, and unassigned shards.

Pending Tasks

Cluster-level pending tasks that can indicate bottlenecks.

CPU Usage

Per-node CPU utilization and OS-level load averages.

Disk Usage

Storage used per node and available disk space.

Thread Pool

Active, queued, and rejected tasks in each thread pool.

Circuit Breakers

Memory estimates and trip counts for request/fielddata/in-flight breakers.

Segment Count

Number of Lucene segments and merge activity.

Fielddata Cache

Fielddata cache size and eviction count.

Triggers & Alerts

Configurable alert triggers

Set up custom triggers in your dashboard to get notified the moment Elasticsearch metrics cross your defined thresholds.

Cluster Health

critical

Fires when cluster status degrades to yellow or red, indicating shard allocation issues.

JVM Heap Usage

critical

Triggers when JVM heap usage exceeds threshold, risking out-of-memory errors and node instability.

Indexing Rate

warning

Alerts when indexing throughput drops below baseline, indicating ingestion pipeline issues.

Search Latency

warning

Fires when average search latency exceeds threshold, degrading user-facing search quality.

Unassigned Shards

critical

Triggers when shards remain unassigned, leaving data under-replicated and at risk.

Thread Pool Rejections

warning

Alerts when thread pool queues overflow and start rejecting requests.

Importance of Elasticsearch Monitoring

Elasticsearch underpins search functionality, log aggregation, and real-time analytics. Without monitoring, cluster degradation, JVM pressure, and unassigned shards can cascade into search outages and data loss.

Detect cluster health degradation before it impacts search availability
Monitor JVM heap to prevent out-of-memory crashes
Track indexing throughput to ensure data ingestion pipelines stay healthy
Identify unassigned shards that leave data under-replicated
Optimize search latency for user-facing applications
