# SDP environment: P4LOG and LOGS are set per instance by sourcing
# /p4/common/bin/p4_vars <instance>. That file is a real shell script (uses
# command substitution, conditionals, etc.), NOT a simple KEY=VALUE file, so
# it cannot be loaded via systemd's EnvironmentFile= directive (systemd will
# silently ignore every non-trivial line, leaving P4LOG/LOGS unset). Instead,
# source it in a shell wrapper before exec'ing the binary.
# Adjust the instance number below as needed:
Environment=INSTANCE=1

ExecStart=/bin/bash -c 'source /p4/common/bin/p4_vars ${INSTANCE} && exec /p4/common/site/log_feeder/p4lf -config /p4/common/site/log_feeder/p4lf.cfg'

# On SIGHUP: reload config and rotate p4lf's own log.
