Node Quick Reference

This guide serves as a handy quick reference for Node operators to efficiently configure, monitor, and troubleshoot their Kaia nodes. It covers common tasks like configuring nodes, understanding and analyzing logs, managing chaindata, and using essential commands. The guide aims to help Node operators smoothly run and maintain their blockchain nodes by equipping them with key information and best practices.

📄️ Configuration

This document explains the configurable properties of the node. Kaia node package ships with good defaults and requires very little configuration. If you changed any settings of a running node, you must restart the node to reflect the changes.

📄️ Node Log

This page details some important or frequently asked logs from Kaia nodes.

📄️ Log operation

Configure Log Rotation

📄️ Frequently Used Commands

How to find the Kaia Directory (Normally “Kaia DIR”)

📄️ Troubleshooting

Where can I find a log file for the running Kaia node using the Kaia binary package?

📄️ Use Chaindata Snapshots

You can start a node from an already-synced database called a chaindata snapshot. A chaindata snapshot is a compressed Kaia data directory.

📄️ Use AWS AMIs

Kaia offers an AWS AMI (Amazon Machine Image) for Kaia endpoint nodes (EN). These AMIs are pre-installed with both the EN software and the chaindata, enabling users to quickly and conveniently launch a fully operational node. With Kaia's AMI, setting up a new endpoint node on demand becomes seamless, allowing for simplifying the process of joining the Kaia network.

📄️ Prune Node Data

This page explains how to delete historical block states to reduce the storage requirement. Kaia offers two approaches for pruning block states:

📄️ Configure Upstream Archive Node: Upstream EN

The Upstream EN (Endpoint Node) feature allows a full node operator to utilize an archive node as an RPC fallback. For more information about full and archive nodes, see the Block Synchronization page.
