SHARDER HEALTHCHECK ALERT

A scheduled Git operation checks the health of the sharder's, ensuring the system's sharder are reliable and robust.

Sharder's HealthCheck GitHub Action - https://github.com/0chain/zus-cicd/actions/workflows/network-sharder-check.yaml

INTRODUCTION

Since sharder's and their alerts are crucial components of the chain, this git-action checks the sharder's health every three hours.

Pay attention to the sharder's rounds if you wish to manually monitor their health.

If any sharder becomes stuck, the git-action will send an alert to devops-0chain Slack Channel.

SCRIPT EXPLANATION

The Script used in GitHub Action - https://github.com/0chain/zus-cicd/blob/main/0chain-scripts/sharder-network-check.sh

Verify that the last_finalized_round are progressing or not using the script above. Send a Slack alert on the devops-0chain channel if it's stuck. Otherwise, pass the check. In order to track last_finalized_round, it looks for the path /v1/sharder/get/stats of particular sharder in the existing network.

Below attached is example of the sharder links where we can manually track Sharder Status -

https://<< network_name >>/sharder01/v1/sharder/get/stats

The script above uses the /dns/network url to retrieve the miner and sharder links - https://<< network_name >>/dns/network
