Examples

Basic Usage

nodetool getseeds

Sample Output

Current list of seed node IPs, excluding the current node's IP: 192.168.1.101, 192.168.1.102, 192.168.1.103

If this node is the only seed or no remote seeds are configured:

Current list of seed node IPs, excluding the current node's IP: (no remote seed IPs)

Configuration

seed_provider:
  - class_name: org.apache.cassandra.locator.SimpleSeedProvider
    parameters:
      - seeds: "192.168.1.101,192.168.1.102,192.168.1.103"

Use Cases

Verify Seed Configuration

nodetool getseeds

Troubleshoot Cluster Discovery

# Check seeds when node can't join cluster
nodetool getseeds

Best Practices

Seed Node Guidelines

Multiple seeds - Configure 2-3 seeds per datacenter
Stable nodes - Choose reliable, long-running nodes
Not all nodes - Don't make every node a seed
