When adding a port that has no previous data collected (standby port in a HA firewall setup) to a multiport graph widget, the graph is not drawn at all and the RRDtool outputs a message “ERROR: absolute path names not allowed when talking to a remote daemon”.
Generating graphs seems to be working fine when all ports have some traffic. Single port graphs work even without any data, they just draw nothing.
