Is it possible to query a host for a specific value? I am looking to just get the on_time value for some switches & outlets (hs200 & kp200) so that I can ultimately run a perl script that will get the data, put it to an snmp oid and then mrtg/rrdtool will graph them. these 2 devices dont support emeter. Here is the sysinfo output:
