[stratanic]

Hello,
I try use the jmx exporter on an old AIX, v6.1, and java 8

It start but nothing to scrape with HTTP version jmx_exporter

Important : I just want Cpu and memory metrics.

config:
JAVA_HOME=/usr/java8_64/jre;export JAVA_HOME
export PATH=/usr/java8_64/jre/bin:$PATH.
export CLASSPATH=/opt/jmx_exporter/jmx_prometheus_httpserver.jar

-----file /opt/jmx_exporter/config.yaml ----
hostPort: localhost:19999
rules:

• pattern: ".*"

command line:
/usr/java8_64/jre/bin/java
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.port=19998
-jar /opt/jmx_exporter/jmx_prometheus_httpserver.jar 19999 /opt/jmx_exporter/config.yaml

error msg:

Your exporter YAML configuration looks incorrect...

hostPort: localhost:19999

hostPort should be the remote applications JMX port.

The standalone JMX Exporter HTTP endpoint listening on port 19999...

-jar /opt/jmx_exporter/jmx_prometheus_httpserver.jar 19999 /opt/jmx_exporter/config.yaml

While the standalone JMX Exporter works, it's discouraged. The standalone JMX Exporter can't get JVM metrics of the remote application.

Thanks, it's working after the change 👍 hostPort: localhost:19998
Awesome, its so hard with old Aix to have some metrics...

Another question: the smaller agent is the http agent? any suggestion if I just want operating system metrics?

I would look at node_exporter_aix https://github.com/thorhs/node_exporter_aix

Not compatible with old aix, lower than 7.1.
Already try...I post an issue.

On a old aix you can just make script and scrapt it with ssh
