It consolidates all logs into one place and provides required features and functionalities
Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to do RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue.

Jörg Kippe - PeerSpot reviewer
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.
