Monitoring Private Blockchain Performance on Non-mining Nodes <Abstract> A private blockchain is potentially used to maintain IoT systems, such as a smart home. In such a blockchain, the mining task (i.e., computation for generating blocks) is too heavy for resource-limited IoT de- vices. Thus, a powerful node with sufficient resources will serve as a miner for the whole blockchain network. Mean- while, the other nodes operate without the mining function (i.e., non-mining nodes). Hence, understanding the performance of non-mining IoT nodes is essential for the private blockchain. In this paper, we aim to monitor the performance of the real devices (i.e., Raspberry Pi), which form a blockchain using the popular private Ethereum. We use on-device tools to track disk space usage, memory usage, CPU utilization, and network usage on non-mining nodes. The collected results within two hours show that it is feasible to monitor the nodesf performance. |
