Optimizing Solana Agave Node Performance: Key Metrics to Monitor
When operating multiple Solana nodes in separate data centers, it is not uncommon for some instances to lag behind others, causing downtime and affecting overall system performance. A key factor contributing to node lag is the number of transactions processed per second (TPS). Here are some metrics to monitor when a Solana Agave node starts to lag:
1.
Transaction Throughput
The number of transactions processed per second (TPS) on each node is a critical metric to track. A higher TPS indicates better system performance. Monitor the following metrics:
- Average TPS: Check if the average transaction throughput is increasing or decreasing over time.
- Peak TPS: Identify any anomalies in peak TPS, as sudden spikes can indicate network issues.
2.
Block Time
The time it takes to process a block on Solana nodes is essential for maintaining consistency with the network’s latency requirements. Monitor:
- Block Time: Check if the average block time is increasing or decreasing over time.
- Average Block Time per Node: Identify any deviations from the average block time.
3.
Gas Price and Usage
Gas price on Solana and overall node utilization can affect performance. Monitor:
- Gas prices relative to current network congestion
- Node utilization rates, which should be above a certain threshold (e.g. 90%);
4.
Node Load Balancing
Ensure that nodes are loaded evenly across data centers and instances. Check for:
- Node Load Balancing: Check that nodes are not overloaded or underutilized.
- Data Center Load Balancing: Ensure that each node is handling an equal amount of traffic.
5.
Network Congestion
Monitor network congestion on the Solana network using tools such as the [solscan]( “network-traffic” metric. This will help identify potential bottlenecks and areas for improvement.
6.
Instance Health
Check the health of each instance (node) to ensure that it is running smoothly:
- Instance Uptime: Check that instances are staying online.
- Instance Errors or Warnings: Identify any issues that could be causing lag.
By monitoring these key metrics, you can quickly identify potential issues with your nodes. Solana Agave and you can take corrective actions to prevent lag and maintain optimal system performance.
