Last weekend we updated our Cisco ASA firewalls. When they came up they re-indexed the interfaces table and now we have incorrect data in all of our interface sensors. (worst part is a customer noticed before we did). I know this has come up in the past and always gets answered with "snmp-server ifindex persist". Unfortunately there is no equivalent command for the ASA. Short of re-naming all the sensors, changing all the associated monthly reports and losing a year's worth of accurate port data (which we promise our customers we will maintain), is there a way to change the index #s that PRTG is using to query the the firewall? The interface number under the settings tab is greyed out and does not allow editing. If I could edit this number all of my problems would be solved (except for the week's worth of invalid data in all the sensor's now).
If that's not possible is it possible to massage the database to move around all the historical data to be under the correct (new) sensor index? Avoiding this problem in the first place, and being able to correct the data when it does, are two highly critical capabilities that are keeping us from completely removing Solar Winds Orion from our network. We do not want Orion, we do not like Orion but we absolutely need Orion when things like this happen.
