Hi, I am using the function 'snmpget' from the SNMP_util version 0.71 in my Perl program and run into some problems:
<snip> ($hrProcessorLoad) = &snmpget ( $host, $hrProcessorLoad_OID ); RRDs::update ($database, "$time:$hrProcessorLoad"); <snap> Works fine if the host is responding and comes back with a nice number (Processorload% in this case). However, if, for some reason my host stops responding to the 'snmpget' (During a crash of the server or something) a 'ZERO' get's added to the RRD during the RRDs::update function on the next line. This ofcourse isn't right: an UNKNOWN should be added to the database! My questions: - What does 'snmpget' return if it doesn't get a response ? - How does RRDs::update handle this response (ie: Should I convert whatever comes out of 'snmpget' to a "U" first so RRDs:update can handle it ?)
