Hello!
I'm implementing a custom circuit breaker in my application spring gateway application, which returns the following event/log:
1/20/23
1:20:28.487 PM |
[app=teste-gateway, traceId=traceid, spanId=spanId, INFO CircuitBreakerCustomConfig : Circuit breaker circuitBreakerName=/test-circuit-breaker-gateway-route onStateTransition=State transition from CLOSED to OPEN fromState=CLOSED toState=OPEN stateName=CLOSED_TO_OPEN
- host = host-ip
- source = http:source-test
- sourcetype = sourcetype_teste-gateway
|
There are about 120 hosts of this application.
If a request to a route starts receiving many errors it will open the circuit, and it will receive the above event, and eventually until the route stabilizes it will change to HALF-OPEN and CLOSED. Each route is represented by the circuitBreakerName field.
So, for example, in an instance/host, the route: /test-circuit-breaker-gateway-route will not have the above event/log until it opens the circuit due to many errors. Then it will receive the log just like the above with stateName=CLOSED_TO_OPEN. Eventually, it will change to stateName=OPEN_TO_HALF-OPEN, and then it can go to stateName=HALF-OPEN_TO_OPEN (if the errors continue) or stateName=HALF-OPEN_TO_CLOSED (if errors stop).
And according with how the requests are being balanced between hosts, I can have hosts where the circuit is currently HALF_OPEN, whereas at the same moment, others hosts have the circuit OPEN for the same route.
I would like to keep track of the routes with an OPEN circuit as it last status (most recent).
It could be something like a Line Chart, that Y-axis is the number of hosts with currently OPEN circuit, and X-axis is time.
So, I imagine that I'll have to check the last status of the above log for every host and search for OPEN. But I'm not really sure how to do this.
Is it possible? How can I do this?
Thank you for any help in advance. And sorry if I wrote anything wrong, english is not my main language.
