Hours of battle with jmxtrans

[trider]

Hello dears!

I decided to try jmxtrans for the delivery of metrics in Graphite for Kafka monitoring.

I has studied documentation https://github.com/jmxtrans/jmxtrans and go install rpm package http://central.maven.org/maven2/org/jmxtrans/jmxtrans/270/jmxtrans-270.rpm to my Kafka server.

Everything was very simple, but it is a complete hoax!

/var/lib/jmxtrans/kafka.yaml

I put kafka.yaml in /var/lib/jmxtrans/. Content of kafka.yaml:

{
  "servers" : [ {
    "port" : "9393",
    "host" : "127.0.0.1",
    "queries" : [ {
      "obj" : "java.lang:type=Memory",
      "attr" : [ "HeapMemoryUsage", "NonHeapMemoryUsage" ],
      "outputWriters" : [ {
        "@class" : "com.googlecode.jmxtrans.model.output.GraphiteWriterFactory",
        "port" : 2003,
        "host" : "10.255.12.2",
        "rootPrefix": "portal.kafka.youla-mq1"
      } ]
    } ]
  } ]
}

Then I changed loglevel to DEBUG in /usr/share/jmxtrans/etc/wrapper.conf.

Starting the agent:

# /etc/init.d/jmxtrans start /var/lib/jmxtrans/kafka.yaml

And nothing happens. I look in a log and I see messages:

2018-11-12 16:40:34 [jmxtrans-result-0] level com.googlecode.jmxtrans.model.output.GraphiteWriter2 [GraphiteWriter2.java:66] - Query result: Result(attributeName=HeapMemoryUsage, className=sun.management.MemoryImpl, objDomain=java.lang, typeName=type=Memory, valuePath=[co
mmitted], value=5211684864, epoch=1542030034877, keyAlias=null)
2018-11-12 16:40:34 [jmxtrans-result-0] level com.googlecode.jmxtrans.model.output.GraphiteWriter2 [GraphiteWriter2.java:73] - Graphite Message: portal.kafka.youla-mq1.127_0_0_1_9393.sun_management_MemoryImpl.HeapMemoryUsage_committed 5211684864 1542030034

Dear developers of the jmxtrans, where are my messages in Graphite???

I'm starting tcpdump -A -s 0 'tcp port 2003 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)' and I don't see that on the Graphite something went.

What do I need to do to get your jmxtrans to send messages to my Graphite?

When I used the Graphite Write last, a little over a year ago, we had not moved to using the GraphiteWriterFactory yet.  We had the same issue where it wasn't flushing the metrics.  Thankfully the older Graphite Writer was solid.

Tnank you! I too just found examples in google. Witch class 'com.googlecode.jmxtrans.model.output.GraphiteWriter' all works. My YAML config:

{
  "servers" : [ {
    "port" : "9393",
    "host" : "127.0.0.1",
    "queries" : [ {
      "obj" : "java.lang:type=Memory",
      "attr" : [ "HeapMemoryUsage", "NonHeapMemoryUsage" ],
      "outputWriters" : [ {

        "@class" : "com.googlecode.jmxtrans.model.output.GraphiteWriter",
        "settings": {

           "port" : 2003,
           "host" : "10.255.12.2",
           "rootPrefix": "portal.kafka.youla-mq1"
        }
      } ]
    } ]
  } ]
}
