A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Can be used to monitor a specific log or do specific actions, but its initial setup is not so easy
I have some customers using SolarWinds Log Analyzer to put some conditions on monitoring information from Windows servers and Linux servers. They use SolarWinds Log Analyzer to see if these conditions appear, and if they appear, generate a notification so that they can investigate what happened…
