Alert on changes to Property Values

Has anyone setup a datasource that would send out an alert if specific properties change their value?

A request from our network team is around triggering an alert when the firmware on some devices changes.  This is being populated into a property for the device but need a way to trigger an alert when its value changes.

We are migrating from Solarwinds and it seems like this was an ability Solarwinds could alert on.

    Does not sound particularly difficult to me.

    This is the right way to do it.

  • I'm not aware of a way to alert on a property change directly, but you can create a ConfigSource (if there isn't one already) that contains the firmware version so LM can alert on it changing that way.

      I will look to see about trying to do it this way as it does seem like the only possible solution that doesn't involve a lot of work scripting out a way to read a custom property out into a different custom property and then comparing it to the old one on some basis.
