Feature Request - Retain Historical Data When Converting From WMI Polling to SNMP Polling

acgarton

I think many people would like to see their historical data retained when switching WMI<>SNMP

Please! Completely losing years of data and benchmarking is just nuts.

What scenario causes you to change polling methods?

WMI comes with Windows OOtB now. SNMP requires a service install. Microsoft reccomends WMI, but I believe a domain admin account is required to utilize WMI - Many see this as a potential security risk and may even be frowned upon if you need to be HIPPA, PCI or SOX compliant. SNMPv3 on the other hand is encrypted and requires it's own special credentials. It's a lot easier to run SNMP across the board. Many devices don't support WMI. WMI is nice - but it has it's caveats.

Our Sonar Discovery automatically grabbed a bunch of nodes using WMI, and now two years later I'm realizing that we can't see network traffic to those nodes. Changing to SNMP obliterates everything, which is crazy.

Servers change, they are upgraded and they have additional roles at times. Plus new monitoring requirements come up all the time. We do nothing but add to this system and WMI is the preferred method. Plus if we are watching custom apps with WMI we might as well move the whole system to WMI.

I would LOVE it if we could do both.... BONUS!!!

I can appreciate that on the technical side there isn't a very clean automatic way to ensure snmp and wmi polled objects match up since they differ in the way they ID things, but it probably wouldn't be terribly difficult to develop a tool that the user can use to at least try to associate the interfaces/volumes/etc across during a conversion. Two columns that basically represent a "list resources" for both polling methods and a dialog where the user gets to choose which ones match and which ones get tossed. Database creates the new interface or volume, and duplicates the historical statistical data from the old InterfaceID to the new interfaceID and bam. In fact thinking it through, if I get some down time I may just build a SQL query to do this. I'll post it up if I come up with anything useful.
