find_error

#!/usr/bin/env bash

# This script is used to help find errors in running bosh VMs by Cloud Controller request ID
#
# Each CC response includes a X-Vcap-Request-Id header. If you have one that has errored with
# a 500 response code, call this script with `find_error <VCAP_REQUEST_ID>`.
#
# This script is not deployed to your bosh VM by default. To install it, run the following script:
#
# apt-get install jq
# wget https://raw.githubusercontent.com/cloudfoundry/cloud_controller_ng/main/scripts/find_error -O /usr/local/bin/find_error
# chmod +x /usr/local/bin/find_error
