node build/app.js server --port=8081 /usr/bin/nohup /usr/local/node/bin/node /var/lib/grafana/plugins/grafana-image-renderer/build/app.js server --port=8081 & |
{ "apps" : { "name":"image-renderer", "script":"node", "args":[ "/var/lib/grafana/plugins/grafana-image-renderer/build/app.js", "server", "--port=8081", ], "error_file":"/tmp/image-renereer-err.log", "merge_logs":true, "log_date_format":"YYYY/MM/DD HH:mm:ss", "min_uptime": "60s", "max_restarts": 30, "autorestart": true, "restart_delay": "60" } } |
