Waiting a better manner to enable the SNMP agent, on each Petals node, add the following system properties on the java command line of the script starting Petals ESB:

-Dcom.sun.management.snmp.port=16161 -Dcom.sun.management.snmp.acl.file=$PETALS_HOME/conf/snmp.acl
{code}where:
* com.sun.management.snmp.port defines the listen port of the SNMP agent.{note} Caution, if Petals ESB runs with a user different from root, you need to use a port upper than 1024. To use a port lower than 1024 with a Petals ESB launches with a standard user, refers to the utility *privbind* (available in standard Ubuntu repository).{note}{note}To use the same port on the same machine for several java processes, refers to snmpd used as proxy.
{note}

* com.sun.management.snmp.acl defines the path file defining ACL of the SNMP agent. It is recommended to create a specific file from $JAVA_HOME/jre/lib/management/snmp.acl where you can configure for example the following ACL entry:

acl = {
{
communities = public, private
access = read-only
managers = localhost
}
}
{code}
{note}Caution, this file should be accessible (read and write: 'chmod 600 xxx') only by the user running the JVM process.{note}
