in the orchestrator where I can find a report with bot executions in the last month, please ?
I think the orchestrator is meant more for monitoring and reports are meant to be found in Insights.
You can check Automations → Jobs → Interval: Last 30 days for a full list of bot executions.
Or you can check Monitoring and get a 1-day-overview of Robots, Processes or Queues.
But for nice monthly reports you’ll want to do either your own dashboard (Elastic/Kibana) or use UiPath Insights.
