Type=oneshot
# Written by configure.py from .env (ALERT_RETENTION_DAYS, ALERT_SUPPRESS_S, ALERT_INDEX). A timer never reads the repo's .env, so without
# this the tunables were settable in name only. The leading - means "carry on if it is absent".
EnvironmentFile=-/etc/vanguard/alerts.env
ExecStart=/usr/local/bin/vanguard-alerts.sh
# Kibana cannot post outside the stack on a basic license, so its rules write into the vanguard-alerts
# index and this is the delivery side. See bin/vanguard-alerts.sh and LOGGING.md.
