Custom SQL Alerts based on the SNMP trap message content

Hi,

I'm able to create Custom SQL alerts on Solarwinds based on Trap Type, thanks to the previous posts in the this forum and especially detailed responses from  RichardLetts on various questions in particular!

But looks like the requirements that we have is bit more complex. The 'Trap Type' is going to be the same in our case for different nodes and the only way we can uniquely identify a SNMP trap  is based on the SNMP 'Trap Details' as highlighted below (It could be swift.storage1, swift.storage2 etc and we will be scaling to hundreds of them)

1. I'm able to get specific values from the Trap Details while configuring the action of a alert, but not able to figure out how do I create Alert itself based on partial content of trap detail itself (for e.g -swift.storage.1)  ?
2. If it's possible to do what is mentioned above, how do I write a reset condition for the same ?
3. We also get an SNMP Traps once the node issue is resolved (some times automatically because of self healing). For example, the above SNMP trap , under trap details,  you can see the message as Low available disk space on Swift.storage.1 and in the trap below it says it's resolved.  Please note that Trap Type will be different for these info traps. How do we reset the alert created in the first trap based on the second trap shown below ?
   

Any inputs or guidelines will be of great help !

Thanks & Regards,

Antony.
