Similar to XML collectors, allow the use of placeholders in parameter values for service monitors so that the value of a node's asset property can be used for parameter values. Example:
Assuming that node x with interface 127.0.0.1 which has service OpenNMS-129 and has asset values 'admin' for username and 'admin' for password, the effective value for the basic-authentication parameter for this interface would be 'admin:admin'. However, if node y with interface 10.0.0.1 has service OpenNMS-129 and has asset property username: 'admin', and password: '@dm1n', the effective value would be 'admin:@dm1n'.
Besides asset properties, allow the use of the following additional placeholders:
