Hi, first, please read the smokeping_extend document if you haven't done so yet. The TelnetIOSPing probe is currently derived from 'basefork', which means that it will ping each target in a separate process. Conversely, the FPing and RemoteFPing probes are derived from 'base', which doesn't allow target-specific variables at all. All hosts monitored with a RemoteFPing probe are pinged from the same host, defined by the 'rhost' probe-specific variable. I think what you want can be achieved by deriving the new TelnetIOSPing probe from 'basevars' instead of 'basefork': this is a base class that offers target-specific variables but not the framework that forks the separate processes. This provides the 'targets' method to access the target-specific variables. See the Smokeping::probes::basevars document. None of the existing probes do this, so you'll probably have to dig in the source a bit. Please ask if you need clarification. Hope this helps, -- Niko _______________________________________________ smokeping-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/smokeping-users
