Logs in UiPath

That depends on your objective. Would you like to monitor ongoing operations, issuing alerts if a robot goes down? Are you interested in the average number of Application or Business Exceptions being thrown by individual executions? When thinking about visualization, who is the target audience and what should they learn from a certain chart?

Also, note that Logs are only one potential data source. Orchestrator offers email alerts, webhooks - and of course, there is the web API (see: Orchestrator Alerts and notifications).

There aren’t many technical limitations - for example, you can easily integrate Nlog into Elastic Search. The questions is rather what needs to be monitored, why, and who will benefit from it.
