Cisco has discontinued the sale of Cisco MARS, prompting the need for a replacement tool, with SolarWinds' Log and Event Manager (LEM) proposed as a viable alternative. The document highlights key features to consider in a replacement, such as deployment, event correlation, compliance reporting, and incident response capabilities. SolarWinds LEM offers advanced search functionalities, extensive compliance reports, and support for a wide range of devices, aiming to provide comprehensive log and event analysis and management.
