Curl the Redlock Prism Cloud API to get alerts from last week then POST them into a Splunk HTTP event collector for alternate archival and analysis. Note the date calculation appends 3 digits of milliseconds from microtime for a total 13 digital epoch value.

# For Mac, date is BSD based. We like GNU date parsing,
# which comes with sideloading date as a renamed gdate util.
# Use Homebrew to install some utilities: https://brew.sh
# brew install coreutils jq

This version is designed to run on a Macbook, which uses slightly different utiltities and versions than what you might find on EL7.

To seed data from the start of the account, the bottom half might look something more like this:

echo "GETing all alerts up to last week..."
curl -s --request GET \
  --url "https://api2.prismacloud.io/alert?detailed=true&timeType=absolute&startTime=1&endTime=${END}" \
  --header 'accept: */*' \
  --header "x-redlock-auth: ${JWT}" \

LINES=$(cat "prisma_alerts_1_${END}.json" | jq -r '.[] | @base64' | wc -l | xargs)
echo "Found ${LINES} alerts..."
