Check system status for Smart ID Messaging

1. To check that Hermod is alive, and view the running instance id and version, use the following command. Make sure to use the correct port:

   Example: Health check

   GET https://my-hermod-server:20400/<contextPath>/info Response 200 OK Body { "id":"hermod.6d99c1", "build":{ "version":"2.0.0.RELEASE", "artifact":"cod-hermod", "name":"Cod Hermod", "group":"com.nexusgroup.cod.hermod", "time":1497432675000 } }

1. To check health information and status for the running Hermod, use the following command. Make sure to use the correct port: 

   Example: Health check

   GET https://my-hermod-server:20400/<contextPath>/health { "status":"UP", "diskSpace":{ "status":"UP", "total":15442378752, "free":2757484544, "threshold":10485760 }, "db":{ "status":"UP", "database":"PostgreSQL", "hello":1 }, "configServer":{ "status":"UP", }, "hystrix":{ "status":"UP" } }

These are the built-in statuses:

1. To check the logs:

   Example: Check logs

   # Login to the host ssh user@machine su - docker # Check logs cd compose/hermod docker-compose logs -f --tail=100

Hermod stores metrics since the last restart. These can be viewed via a http request.

1. To view the Hermod metrics:

   Example: Check metrics

   # Find the current port for an Hermod instance (33700 in this case) docker-compose ps | grep hermod_hermod hermod_hermod_1 ./fatjar-entrypoint.sh app ... Up 0.0.0.0:33700->20400/tcp # Use curl to get metrics (You can use https://jsonformatter.curiousconcept.com/ to format the output) curl http://localhost:33600/<contextPath>/metrics { "mem":673568, "mem.free":336830, "processors":2, "instance.uptime":57997012, "uptime":58006488, "systemload.average":0.0, "heap.committed":579072, "heap.init":112640, "heap.used":242241, "heap":1585664, "nonheap.committed":96768, "nonheap.init":2496, "nonheap.used":94496, "nonheap":0, "threads.peak":50, "threads.daemon":23, "threads.totalStarted":2493, "threads":49, "classes":10343, "classes.loaded":10343, "classes.unloaded":0, "gc.ps_scavenge.count":22, "gc.ps_scavenge.time":294, "gc.ps_marksweep.count":2, "gc.ps_marksweep.time":142, ... }
