When should I perform a VM Hard Reset instead of a service restart?

A hard reset should be used as a last resort when the VM loses network connectivity, encounters DNS resolution failures, or when the metadata server becomes unreachable.

How does this skill prevent data gaps in blockchain metrics?

It provides automated status checks and rapid recovery workflows to minimize downtime, alongside verification scripts that confirm data is successfully reaching the ClickHouse database.

What specific VM does this skill manage?

It is optimized for the eth-realtime-collector instance located in the us-east1-b zone of the eonlabs-ethereum-bq GCP project.

What prerequisites are required to use these workflows?

You must have the gcloud CLI installed and configured with the appropriate credentials and project permissions for the eonlabs-ethereum-bq project.

Can I use this for general GCP VM management?

While the skill contains specific logic for the eth-collector, the patterns for systemd management, gcloud SSH commands, and journalctl logging are applicable to many Linux-based cloud environments.

クラウドインフラストラクチャ

Manages and troubleshoots GCP VM instances running real-time blockchain data collectors.

概要

This skill provides a comprehensive suite of operational commands for managing the eth-realtime-collector on Google Cloud Platform. It enables users to monitor systemd service health, analyze real-time logs via journalctl, perform safe service restarts, and execute VM hard resets when critical network connectivity issues occur. Designed specifically for high-availability blockchain data environments, it ensures that Ethereum network metrics are collected without gaps by providing structured workflows for infrastructure recovery and ClickHouse data flow verification.
