The two error messages are both complaining because the RRD database for the CPU target does not exist. This does not exist because MRTG has not yet successfully polled this target. You should check the output of MRTG when run directly on the cfg file in question - there may be an error coming about polling the cpu target. I assume the txt file is your host template? One point is that the Target[] line should come first (before all other directives for that target) although this is not the cause of the problem. You should check that the polling definitely works - maybe you have the wrong OID or a nonexistant OID for this device? You are polling for OID 1.3.6.1.4.1.9.2.1.58.0 Make sure this exists. Make sure it really is a percentage number - sometimes CPU usage is given in hundredths of a percent and you need to add ' / 100' to the end of the Target line to compensate. There is also a cisco and generic device host template available in the cfgmaker forum on this board which might be useful for you, as they check for the existance of the OID. Steve |
