Raw Blame History

#!/usr/bin/perl
#
# This is the master daemon that manages all periodically run processes on Striker dashboards, Anvil! cluster
# nodes and DR hosts.
#
# Exit codes;
# 0 = Normal exit or md5sum of this program changed and it exited to reload.
# 1 = Not running as root.
# 2 = Unable to connect to any database, even after trying to initialize the local system.
#
# TODO:
# - Need to check what kind of machine this is and not prep the database unless its a dashboard.
# - Add a "running: pending,yes,done,dead" and show an appropriate icon beside jobs
# - Decide if holding before the main loop until 'systemctl is-system-running' returns 'running' is a good
# idea or not.
# - Write the status of this and the scancore daemon to /etc/anvil/anvil.motd and symlink it to /etc/motd.d/
# - Write a script that runs in crontab at UTC 17:00 that sends an email if Scancore or anvil-daemon are disabled.
# - Examine limites in: https://www.freedesktop.org/software/systemd/man/systemd.exec.html#LimitCPU=
# - Write a background program to scan the BCN and uses OUI data to try and find / auto-configure PDUs and UPSes
# -
# - Increase DRBD's default timeout
# - Check for and enable persistent journald logging
#
# NOTE:
# - For later; 'reboot --force --force' immediately kills the OS, like disabling ACPI on EL6 and hitting the
# power button. Might be useful in ScanCore down the road.
