Hystrix Dashboard is not showing up Rejected count

[ramkarna]

Hi,
Hystrix Dashboard is not showing up rejected count, though the hystrix stream json response has rejected count. We are tried Hystrix Dashboard version hystrix-dashboard-1.3.18 and hystrix-dashboard-1.4.0-RC5. We tried deploying on Tomcat 8

and Liberty profile.
Hystrix Stream output:
{"type":"HystrixCommand","name":"operation","group":"WebService","currentTime":1422043075322,"isCircuitBreakerOpen":false,"errorPercentage":5,"errorCount":2,"requestCount":39,"rollingCountCollapsedRequests":0,"rollingCountExceptionsThrown":2,

Please let us know the solution if any.

I'll take a look, @ramkarna

[dsukner]

Have the same problem. Is there a soution?

[mattrjacobs]

@ramkarna / @dsukner I'm focusing on getting the command internals working before focusing on the dashboard. In all likelihood, I will try to get an RC out with just internal changes so that I can get testing started on that before I turn my attention to the dashboard. I'm happy to review any changes you make, though.

[ramkarna]

Is failure types like SHORTCIRCUIT, REJECTED_SEMAPHORE_EXECUTION are treating as an errors?

[ramkarna]

In hystrixCircuit.html rejected count displaying only for THREAD strategy.
<% if(propertyValue_executionIsolationStrategy == 'THREAD') { %>
<%= addCommas(rollingCountTimeout) %>
<%= addCommas(rollingCountThreadPoolRejected) %>
<% } %>
If you add the below code then it will fix the issue and rejected count will show it up for SEMAPHORE
<% if(propertyValue_executionIsolationStrategy == 'SEMAPHORE') { %>
<%= addCommas(rollingCountSemaphoreRejected) %>
<% } %>

[mattrjacobs]

Thanks for investigating, @ramkarna. Once I get around to the dashboard set of tasks, I'll include your change

[mattrjacobs]

I believe this is fixed in #728. @ramkarna / @dsukner - Can you confirm this looks the way you expect?

[ramkarna]

Sure will take a look at it and confirm.

[ramkarna]

Fix is working.
