I am using trial version.I have installed filebeat,auditbeat,winlogbeat agent on target systems. The prebuilt jobs which i can use are 1. siem-api-rare\_process\_linux\_ecs 2. siem-api-rare\_process\_windows\_ecs 3.siem-api-suspicious\_login\_activity\_ecs but from elasticsearch reference I should use all of these [https://www.elastic.co/guide/en/siem/guide/7.x/prebuilt-ml-jobs.html](https://www.elastic.co/guide/en/siem/guide/7.x/prebuilt-ml-jobs.html) why can I use only these 3 jobs? Does it because license type? ---

No, this isn't because of the license type - rather, the version that you're on. Later versions have more built-in ML jobs. I believe that v7.5 has as many as 23 built-in jobs ---
