We have a same need that basically to import monitoring data from other data source that does not have SNMP agent. The data will be fed to NetXMS server for reporting/monitoring purpose. Data format may look like following:
Jan 06 01:22:45 DataReceived 12kb
Jan 06 01:22:46 DataSent 3kb
Jan 06 01:23:40 DataReceived 12.5kb
Jan 06 01:23:41 DataSent 3.6kb
Any suggestion from you all that import these and report from NetXMS will be appreciated.
