# This script obtains diagnostic data for Palo Alto Networks Support to troubleshoot an existing issue, should it recur.
# ATTENTION: The PAN CLI commands were provided by PAN Support for execution via ttl (Tera Term) and have been ported to a shell script.
#            To be tested for at least a week with monitoring of resource utilization and checks for any adverse impact, before deployment on Production.
# Set up the following crontab for housekeeping:
# 0 * * * * find <dir> -type f -name "pandiag_2020*.txt" -mmin +120 | xargs -i gzip {}
# * * * * 0 find <dir> -type f -name "pandiag_2020*.txt.gz" -mtime +7 | xargs -i rm -f {}
