Hey @Misha, Elasticsearch is used to store messages logged by the Robots. Logs can be sent to ElasticSearch and/or to a local SQL database. By default, they are both used, thus enabling you to have non-repudiation logs. When using both ElasticSearch and SQL, they do not affect each other if one of them encounters a problem. These parameters can be changed from the
web.config file (C:\Program Files (x86)\UiPath\Orchestrator)
If you wish to use ElasticSearch, please note that although it is a cross-platform product, which runs on Windows, Linux, or Unix, it requires Java. The minimum recommended version of Java Runtime Environment is 1.8.131.
If the computers are in a domain, you have to ensure that they are added in the Computers section of the domain server, in Active Directory Users and Computers. This step is required because the computer name is used during the installation process.
