The difference is subtle but important.<br><br></div><div>Try doing a tcpdump capture on the host with collectd configured. You will want to verify that the snmp request is going and there is a response. If there is a response from the tape library, check the payload and make sure there is a value and not an error.<br><br></div><div>If all this is working and graphite still is not showing anything, increase the logging level to debug to see more information in the logs. Remember to turn down logging when you are done.<br><br></div><div>Other things to check: is the collectd snmp module installed (there should be an snmp.so module within collectd's lib/lib64 directory); is the plugin loaded ("LoadPlugin snmp") <br></div><div><br></div><div>Lastly, I don't think that value is a table. You could use a mib browser like mbrowse or look at the MIB to verify. I would set Table to false and optionally an Instance string.<br><br></div><div>Giovanni<br></div></div></div>
