// Usage Instructions:
|
||||
// Paste below query in log analytics, click on Save button and select as Function from drop down by specifying function name as FireEyeNXEvent and specifying Legacy Category.
|
||||
// This function maps FireEye NX events to normalization schema (https://docs.microsoft.com/azure/sentinel/normalization-schema).
|
||||
// Function usually takes 10-15 minutes to activate. You can then use function alias from any other queries (e.g. FireEyeNXEvent | take 10).
