Dashboard & Overview

Dashboard Overview​

The Secan dashboard provides a high-level overview of all configured clusters, allowing you to quickly assess the health and status of your Elasticsearch infrastructure.

Dashboard Features​

Cluster List​

The dashboard displays all your configured clusters in a table with the following information:

  • Cluster Name: Display name of the cluster
  • Health Status: Current cluster health (green, yellow, red, or unreachable)
  • Node Count: Number of nodes in the cluster
  • Shard Count: Total shards across all indices
  • Index Count: Number of indices in the cluster
  • Document Count: Total documents across all indices
  • Disk Usage: Total disk space used and percentage utilization

Health Status Colors​

  • Green: All shards are allocated and cluster is healthy
  • Yellow: All primary shards are allocated, but some replicas are missing
  • Red: One or more primary shards are unallocated
  • Unreachable: Cannot connect to the cluster

Summary Metrics​

At the top of the dashboard, view aggregate statistics across all clusters:

  • Total Clusters: Number of configured clusters
  • Total Nodes: Combined node count across all clusters
  • Total Indices: Sum of all indices
  • Total Documents: Combined document count
  • Total Shards: Sum of all shards
  • Total Disk Usage: Aggregate disk consumption with percentage

Auto-Refresh with Smart Caching​

The dashboard automatically refreshes at configurable intervals to keep statistics current:

  • Configurable Refresh Rate: Set refresh interval from 5 seconds to 1 minute, or disable auto-refresh
  • Smart Caching: Cache duration automatically calculated as 1.5x refresh interval for optimal performance
  • Manual Refresh: Click the refresh button to update data immediately
  • Loading States: Skeleton loaders show while data is being fetched

Cluster Selection​

Click on any cluster in the table to navigate to the Cluster Details page where you can explore nodes, indices, and perform management operations.

Prometheus Metrics Integration​

The dashboard integrates with Prometheus to provide historical metrics and trending data:

  • Time Range Selection: Choose from preset ranges (last 24 hours, 7 days, custom)
  • Historical Trends: View how cluster metrics have changed over time
  • Metrics Aggregation: See aggregated metrics across all clusters

Performance Optimizations​

Client-Side Caching​

  • React Query Cache: Uses React Query for intelligent data caching
  • Stale Time: Data marked as stale after cache duration expires
  • GC Time: Cached data automatically cleaned up after extended periods
  • Deduplication: Multiple requests for same data are deduplicated

Efficient Data Loading​

  • Skeleton Loaders: Visual feedback during data loading
  • Parallel Fetching: Cluster stats fetched in parallel for faster loading
  • Error Handling: Graceful handling of unreachable clusters

What's Next​

Once you've identified a cluster to manage, proceed to Cluster Details to explore nodes, indices, and other cluster-specific features.
