Heads up - What else you should know 

  • On October 18, 2021, we will be implementing synthetics monitoring behavioral changes for Internet Explorer (IE) 11 and Firefox, and deprecating support for Chrome versions 64 and 83 browsers. This change is part of an effort to bring our synthetics monitoring to a single browser architecture, allowing us to innovate faster and provide more value-added capabilities to better support our customer needs. Read our knowledge base article for more information, including instructions and support resources to avoid any disruption to your services.

  • AppDynamics' technical certification recipients can now access official digital badges. Newly launched, each badge consists of an image and metadata that are uniquely linked to the individual and the specific certification. Shared at-will on resumes, social media, email, and more, this credential grants viewers immediate access to validated information, including its issuance by Cisco and AppDynamics.
