Actions for Microsoft Azure NSG Flow Logs

Get Logs

Fetch Flow log tuples of Azure NSG Flow. Blocks are generated per minute. So query on larger time range will carry more number of requests(one request per minute of time range). As an example one hour range will hit Azure servers 60 times to fetch all data which are divided into 60 files (and would be quite slow)

Input Field
