如何从 jboss cli 读取引导错误？

Question

When using hot-deploy via jboss-cli ( deploy --file on_controller.war ) and there is a problem with deploying it, there is some output describing the problem, for example (not actually that pretty printed. ^^):

{
    "WFLYCTL0080: Failed services" => {
        "jboss.undertow.deployment.default-server.default-host./THE_WAR" =>
            "< some description containing exceptions etc >"
    }
}

When not using hot-deploy, for example when using <fs-archive /> in standlone.xml ;
how do I read this errors using jboss-cli?

I know there is the deployment-info command, but that only tells whether a deployment failed, but not why .
I also tried /deployment=*:query() , but it also just contains only whether the deployment failed.

Additionally :read-attribute(server-state) will return "running" even when were error during boot.

You can try /core-service=management:read-boot-errors :

[standalone@jboss:9990 /] /core-service=management:read-boot-errors
{
    "outcome" => "success",
    "result" => []
}

Because that output can be a little bit hard to parse when using automation , you can also use JBoss' HTTP Management API , which will give you JSON:

$ curl --digest --location --dump-header - http://$JBOSS_HOST:9990/management/ \
    --header "Content-Type: application/json" --data - --user admin <<EOT
{
    "address": {
        "core-service": "management"
    },
    "operation": "read-boot-errors",
    "json.pretty": 1
}
EOT

}
