Watchdog

Introduction

SKALE Watchdog is microservice running on every SKALE supernode for providing SLA agents with supernode performance metrics. It also can be used for external monitoring goals (validators can use it in their monitoring tools).

Watchdog is a Python script running in docker container with Flask web server that provides simple REST JSON API available on port 3009 (http://YOUR_SKALE_NODE_IP:3009). Currently, Watchdog can give data on all SKALE supernode docker containers, health checks of sChains and SGX server, ethereum supernode endpoint status, and hardware information.

[NOTE] Node CLI automatically opens port 3009 on the machine using iptables. Be sure that port 3009 is open for the supernode’s external network for Watchdog to work.

REST JSON APIs

/status/core

Description

Returns data on all SKALE containers running on a given node. These are containers with prefix skale_, including base containers and pairs of sChain and IMA containers, where every pair corresponds to a certain sChain assigned to this node.

Here is a list of the base containers:

  • skale_transaction-manager
  • skale_admin
  • skale_api
  • skale_mysql
  • skale_sla
  • skale_bounty
  • skale_watchdog
  • skale_nginx

Docker container name patterns for sChain with name SCHAIN_NAME are the following:

  • sChain: skale_schain_SCHAIN_NAME
  • IMA: skale_ima_SCHAIN_NAME

Usage

Terminal window
$ curl http://YOUR_SKALE_NODE_IP:3009/status/core
