# Microsoft Edge on macOS sometimes will get stuck using 100% CPU endlessly, requiring a relaunch to stop.
# See issue at https://techcommunity.microsoft.com/t5/discussions/edge-browser-100-cpu-requires-force-quit-macos-mojave-and-v91-0/m-p/2441462/highlight/true#M48074
#
# This script will display a macOS notification if Microsoft Edge has been using more
# than 90% CPU continuously for more than 10 minutes. It only checks the main
# Microsoft Edge process, not the Microsoft Edge Helper processes.
#
# Save it to ~/bin/cpu-threshold-alert-microsoft-edge

The following worked with Elastic Cloud, Elasticsearch & Kibana v7.6.0. It should be pretty close for other kinds of deployments. Before starting, make sure you have the right license level that allows SAML.

Create SAML App in Google Workspace:

• Navigate to the SAML apps section of the admin console
• Click the Add button and choose to "Add custom SAML app"
• Write down the Entity ID and download the Idp metadata file
• Choose application name, description and add logo
• In the "Service Provider Details" screen add the following:
