Netflix-Eureka has a well defined RESTful API to get status of all services currently registered with it. We can pull this information anytime with a simple GET request.
I want to setup an alerting system that will notify someone either by email or sms if a service goes DOWN or UP.
Currently I am trying to achieve this using hawkular-alerts. I was wondering if this can be possible without writing much of custom code.
If there is some other better solution, please quote.
Scenario:
Eureka provides an endpoint something like http://domain/eureka/v2/apps on which if we make a GET request, it returns a JSON something like:
{
"applications": [
{
"name": "SERVICE01",
"status": "UP"
},
{
"name": "SERVICE02",
"status": "DOWN"
}
]
}
Now based on this resultant JSON, I need to fire an alert email telling SERVICE02 is down.
Is it possible with hawkular-alerts?
I am not familiar with Eureka but I guess you can use a similar example as defined in
https://github.com/hawkular/hawkular-alerts/tree/master/examples/hello-world
Basically, you can create a script to feed data into Hawkular Alerting and define rules there to detect your scenario.
If you give me more details I can help with a prototype.
