Health Check API Runscope Blog Build a Health Check API for Services Underneath Your API TL;DR • Create separate health check API endpoints for all services! • Set up notifications!

Health Check API How do we monitor them? • MySQL • Redis • BIND • etc ... They don't come with (HTTP) RESTful APIs ! Communicate over lower-level protocols like TCP and UDP.

Good Example! ElasticSearch $ curl localhost:9200/_cluster/health { "cluster_name": "pairs-jp-es-cluster", "status": "green", "timed_out": false, "number_of_nodes": 6, "number_of_data_nodes": 5, "active_primary_shards": 8, "active_shards": 32, "relocating_shards": 0, "initializing_shards": 0, "unassigned_shards": 0, "delayed_unassigned_shards": 0, "number_of_pending_tasks": 0, "number_of_in_flight_fetch": 0, "task_max_waiting_in_queue_millis": 0, "active_shards_percent_as_number": 100 }

Create Health Check API Endpoints! Check MySQL connection "databaseserver:3306", "username" => "root", "password" => "password" ]; header('Content-type: application/json'); $link = new mysqli($config['server'],$config['username'],$config['password']); if ($link->connect_errno) { http_response_code(503); echo('{ "status": "Unable to connect" }'); } else { http_response_code(200); echo('{ "status": "Connection successful." }'); }

Caution Do not open to the public ! Access control by ip address or authentication. nginx Advent Calendar 2015 Day21 nginx APIΤϯυϙΠϯτຖͷΞΫηε੍ޚ
