# install-kamatera.sh — install/upgrade the cross-platform failure-collector on Kamatera.
#
# Run on Kamatera as root:
#   curl -fsSL http://100.65.187.120:3333/static/cncp-collector-kamatera.tar.gz | tar xz -C /root/Projects/
#   bash /root/Projects/cncp-failure-collector/install-kamatera.sh
#
# Or scp the tarball then extract + invoke.
#
# What it does (idempotent):
#   1. npm install (only if node_modules missing or package.json changed)
#   2. Writes /root/Projects/cncp-failure-collector/ecosystem.kamatera.config.js
#      with CNCP_URL pointed at Mac2's tailnet IP + host=kamatera + Linux log paths
#   3. pm2 start (or restart) cncp-failure-collector
#   4. pm2 save
#
# CONFIG (override via env before invoking):
#   MAC2_TAILSCALE_IP   default 100.65.187.120
#   POLL_INTERVAL_MS    default 30000
#   LINUX_LOG_PATHS     default /var/log/nginx/error.log,/var/log/syslog
