JMX on collector app

[mariusrugan]

Hi,

i'm trying to enable JMX on collector app to inspect stats i've tried adding in appwiring.xml

<context:component-scan base-package="com.ebay.pulsar.collector.servlet" />

<context:mbean-export default-domain="com.ebay.pulsar.collector"/>

but i cannot start the app:

14:08:25.024 [main] ERROR com.ebay.jetstream.application - Failed to start ApplicationUnable to register MBean [EPL] with key 'EPL'; nested exception is javax.management.MalformedObjectNameException: Key properties cannot be empty Failed to start application: org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [EPL] with key 'EPL'; nested exception is javax.management.MalformedObjectNameException: Key properties cannot be empty org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [EPL] with key 'EPL'; nested exception is javax.management.MalformedObjectNameException: Key properties cannot be empty

app startup params: -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=18002 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false

Any ideas for correct "wiring"? thanks

Hi Sharad, thanks. i've sorted it out finally via

<bean id="mbeanServer" class="org.springframework.jmx.support.MBeanServerFactoryBean">
    <property name="locateExistingServerIfPossible" value="true" />
</bean>

(bottom of https://github.com/MariusRugan/realtime-analytics/blob/develop/collector/buildsrc/JetstreamConf/appwiring.xml)

However, running it and inspecting it with jconsole, the object wasn't incrementing it's Atomic "stores" (e.g. counters). Was this intentional or a bug slipped in? Fixed now by wiring it as beans.

(this endeavour was ment to fix JMX so i can jconsole it in docker to see final step in testing traffic generator in docker)

Actually we used Spring JMX annotations but we did not use jmx. You don't require to use jmx console to access it. All of beans exposed by the app can be accessed via a browser. When start the app, the -p port is the http port to access the monitoring page. I suggest to use that to monitor things rather than JMX.

Best regards, Xinglang

hi, thanks for the suggestion & clarification. will give it a try.

btw, i had this question in mind, related to the management port and what is served there. I thought i have a config problem given the fact the page is very different (unstyled) than the ones screenshoted on the pulsar demo (publisher/subscriber) but i see now your screenshot so probably i'm not missing anything.

Can't find the wiki link right now, but i've see it couple of times :)

I think you may mix the two screenshots: monitor page screenshot and dashboard screenshot.

Above is just for monitoring, it is very raw. :-)

The dashboard screenshot is more for reporting demo. here is the link: https://github.com/pulsarIO/realtime-analytics/wiki/PulsarIO-Demo

thanks for clarification, was ref. to this https://github.com/pulsarIO/jetstream/wiki/images/configuration_screenshot.png but i know now it's not 'management' but jetstream specific bootstrap.

thanks again
