Problem with springboot java and jmxtrans-agent

[maogouste]

Hello,

I'm trying to add jmxtrans-agent to internal java with springboot application.

It's started with :

/opt/jdk1.8/bin/java -javaagent:/servers/jmxtrans-agent/jmxtrans-agent.jar=/servers/jmxtrans-agent/jmxtrans-agent.xml -Dinfluxdb_instance=dots-server_01 -Dorg.jmxtrans.agent.JmxTransAgent.diagnostic=true -Dorg.jmxtrans.agent.util.logging.Logger.level=TRACE -Djavax.net.ssl.trustStore=/etc/digiplug/cacerts -Djavax.net.ssl.trustStorePassword=changeit -jar /servers/dgpapps/dots/dots-server.jar --slot.id=01

It correctly generates some point and finishes with a stack :

On the same server, I have a logstash that export correctly with the same xml and jar. I can graph it.

I see the "Ignore exception flushing metrics" exception at https://github.com/jmxtrans/jmxtrans-agent/blob/master/src/main/java/org/jmxtrans/agent/JmxTransExporter.java

But, I have no idea what it may mean.

I tried to debug by myself, but couldn't progress further.

The HTTP connection from jmxtrans-agent embedded in your spring boot app to influxdb fails with a socket timeout ("SocketTimeoutException: Connect timed out").

You are likely to have a firewall issue between the springboot server and the influxdb server.

Could you try a curl http://xx.yy.zz.aa:8086 from the springboot server to verify that the network connectivity to the influxdb server is opened?

[maogouste]

I thank you for your fast answer.

A curl from the server produces data.

curl -G 'http://xx.yy.yy.aa:8086/query?pretty=true' --data-urlencode "db=java_db" --data-urlencode "q=SELECT mean("value") AS "mean_value" FROM "java_db"."autogen"."ThreadCount" WHERE time > now() - 5m AND "host"='' AND "instance"='logstash' GROUP BY time(10s)"

retrieves :

{
    "results": [
        {
            "statement_id": 0,
            "series": [
                {
                    "name": "ThreadCount",
                    "columns": [
                        "time",
                        "mean_value"
                    ],
                    "values": [
                        [
                            "2017-09-20T08:26:40Z",
                            54
                        ],
...snip...
                            54
                        ],
                        [
                            "2017-09-20T08:31:40Z",
                            null
                        ]
                    ]
                }
            ]
        }
    ]
}

Furthermore, on the same server, a logstash is tooled the same way with the same jmxtrans-agent jar and xml without problem

But, it succesfully generates some data points before failing in stack.

it looks like something is interfering with the normal action of jmxtrans-agent.

[kerlandsson]

That error should not stop the reporting, it is just a warning, and as it says in the message, it should be ignored. What is logged after the error? You mention that the reporting finishes, could you elaborate on that?

Nothing is logged after the error. But the ConsoleOutputWriter keep on producing data.

You mention that the reporting finishes, could you elaborate on that?

Influxdb have one point at the start of the java. And nothing. 2017-09-20 10:01 GMT+01:00 Kristoffer Erlandsson <notifications@github.com>:

@maogouste I have improved the troubleshooting messages with #112

Can you please test the jmxtrans-agent snapshot https://oss.sonatype.org/content/repositories/snapshots/org/jmxtrans/agent/jmxtrans-agent/1.2.7-SNAPSHOT/jmxtrans-agent-1.2.7-20170920.100756-1.jar and share with us the error message.

[cyrille-leclerc]

@maogouste you have a connect timeout when the JVM tries to open an HTTP socket on port 8086 to the IP xx.yy.zz.aa.

If a curl http://xx.yy.zz.aa:8086 is successful when the JVM is not, then there may be an http proxy issue. Could you go through an http proxy when using curl but not when using java or vice versa?

Can you try to execute from the application server the following command to test a jvm access to :http://xx.yy.zz.aa:808

jrunscript -e "println(new java.net.URL(\"http://xx.yy.zz.aa:8086\").openConnection().getResponseCode())"

[maogouste]

It says 404

[cyrille-leclerc]

I think I understood, the http connection from your java application seem to go through a Sock Proxy as you can see java.net.SocksSocketImpl.connect in the stack trace.

Shouldn't you exclude the ip address of your influxdb server from your jvm proxy config?

The jmxtrans-agent connection should pass directly. No proxy of any kind needed.

But, proxies are defined for the corporate application.

Is it possible to define our own? In this case, none?
