# Example MP runtime plugin (Bash) for LMCache multiprocess server.
|
|
#
|
|
# In MP mode the config JSON contains aggregated sections:
|
|
# mp_config, storage_manager_config, obs_config
|
|
#
|
|
# This script demonstrates:
|
|
# 1. Reading the MP-mode environment variables.
|
|
# 2. Extracting fields from the aggregated JSON via jq.
|
|
# 3. Running a periodic heartbeat loop.
|
|
#
|
|
# Requires: jq (optional, falls back to raw echo)
|
|
|
|
# Graceful shutdown
|
|
