Asking for otel-auto-instrumentation-java agent

[SusanaG97]

Hi. I'm trying to run my java application on IntelliJ, with the use of the mirrord plugin, and I'm getting this error:

Picked up JAVA_TOOL_OPTIONS: -javaagent:/otel-auto-instrumentation-java/javaagent.jar Error opening zip file or JAR manifest missing : /otel-auto-instrumentation-java/javaagent.jar Error occurred during initialization of VM agent library failed to init: instrument

I have downloaded this java agent and set the JAVA_TOOL_OPTIONS to its location (correctly, I can verify by echo in any terminal). But seems it's not sticking here, as the location shown on the error doesn't match.

This is my mirrord config:

{
"feature": {
"env": {
"override": {
}
},
"network": {
"dns": true,
"incoming": {
"mode": "steal"
},
"outgoing": true
},
"fs": "read"
},
"target": {
"path": {
"deployment": "broker"
},
"namespace": "runtime"
}
}

Any help would be really appreciated!

Hey,
It's probably picking it up from the remote, use this config

{
"feature": {
"env": {
"override": {
}
},
"network": {
"dns": true,
"incoming": {
"mode": "steal"
},
"outgoing": true
},
"fs": "read", "local": ["/otel.+"]
},
"target": {
"path": {
"deployment": "broker"
},
"namespace": "runtime"
}
}

or try this

{
"feature": {
"env": {
"override": {
}
},
"network": {
"dns": true,
"incoming": {
"mode": "steal"
},
"outgoing": true
},
"fs": "read", "local": ["/$"]
},
"target": {
"path": {
"deployment": "broker"
},
"namespace": "runtime"
}
}

We read jars locally by default, but it could be that it tries to list the directory first, which is resolved remotely ('/)
I'd put the otel binary in a different directory that can be marked safely as local (since marking / local might have other implications)

Thank you!
I've tried both configs and the error remains. I've also placed the required agent jar in /home and it made no difference

it's quite weird - would you like to schedule to investigate it together?

ahh I think I know what happens - it has this in the remote pod and tries to load it locally.
You can just exclude that env from being fetched with this config:

{
"feature": {
"env": {
"override": {
},
"exclude": ["JAVA_TOOL_OPTIONS"]
},
"network": {
"dns": true,
"incoming": {
"mode": "steal"
},
"outgoing": true
},
"fs": "read"
},
"target": {
"path": {
"deployment": "broker"
},
"namespace": "runtime"
}
}

setting JAVA_TOOL_OPTIONS here:
"env": {
"override": {
"JAVA_TOOL_OPTIONS": ""
}
}
allows me to at least run the application
