In one of the Solarwinds NPM 10.3 installs that I support, the alerts have started to come in with variable names embedded instead of the actual data. Both custom properties and native properties are being sent. For example, one of my alerts comes in with ${CustomerName} - DCFP01-Physical Memory - ${IP_Address} is Up.
I've checked both the SQL server performance and the application server performance as well as the overall polling load and none of the stats seem out of whack.
Any ideas?
