Hi,

I'm adding check_jmx plugin in icinga2, but I'm not sure if my configurations are correct because I'm getting an error

Here's my configurations for check_jmx

commands.conf


object CheckCommand "check_jmx" {
import "plugin-check-command"
command = [ PluginDir + "/check_jmx" ]
arguments = {
"-U" = "$service_url$"
"-O" = "$object_name$"
"-A" = "$attrib_name$"
"-K" = "$comp_key$"
"-w" = "$warn$"
"-c" = "$crit$"
"--username" = "username"
"--password" = "passwd"
}
}

service_jmx.conf


#apply service for jmx

apply Service "jmx" to Host {
import "generic-service"
check_command = "check_jmx"
vars.service_url = "service:jmx:rmi:///jndi/rmi://" + host.name + ":9999/jmxrmi"
vars.object_name = "java.lang:type=Memory"
vars.attrib_name = "HeapMemoryUsage"
vars.comp_key = "used"
vars.warn = "731847066"
vars.crit = "1045495808"

assign where host.vars.os == "Linux"
}

can someone help me to fix this error.

thanks!
