vRealize Log Insight for vCenter Server – End of Availability
VMware has just announced that the vRealize Log Insight for vCenter Server (the "free" version that is licensed with the vCenter Server license key) will be end of life August 23th. 2019.
This does not mean that VMware is dropping product, but only remove the ability to use the "free" version, and 4.6.x will be the last version that accepts the vCenter Server license key.
