Starting with RHQ-Metrics

[theute]

I am trying to install and play with RHQ Metrics but facing some installation issue.

I have Cassandra 2 running locally (On Fedora) with default options (default port 9042)

I ran RHQ Metrics Server with defaults:

java -jar rhq-metrics-server-0.1.0-SNAPSHOT-fat.jar

I get the following log:

log4j:WARN No appenders could be found for logger (com.datastax.driver.core.FrameCompressor).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
May 13, 2014 2:14:57 PM org.vertx.java.core.logging.impl.JULLogDelegate info
INFO: Succeeded in deploying module

Then I try to populate:

curl -i -X POST http://127.0.0.1:7474/rhq-metrics/ -d@/tmp/toto -HContent-Type:application/json

But it complains

curl: (7) Failed connect to 127.0.0.1:7474; Connection refused

Did I miss something ?

You are running the wrong JAR file. You should be executing the fat JAR produced in the metrics-rest module, e.g.,

$ java -jar target/rhq-metrics-rest-0.1.0-SNAPSHOT-fat.jar

You will find some documentation for running that REST module in the README at rhq-metrics/metrics-rest at master · rhq-project/rhq-metrics · GitHub. The metrics-server module produces a Vert.x module that is the core module in that it talks directly to Cassandra via the DataStax driver. The metrics-rest module provides REST endpoints that in turn communicate with the core server via the event bus.

Arf, indeed...

curl -i -X POST http://127.0.0.1:7474/rhq-metrics/test/data -d@/tmp/toto -HContent-Type:application/json

Worked

With /tmp/toto being:

[
{
 "timestamp":1398891828116,
 "value":12.3
}
]

Thanks !
