安装njmon_tool​

[root@njmon home]# wget home]# unzip njmon_tools_v50.zip[root@njmon njmon_tools_v50]# cat njmond.conf {"njmon_port": 8181,"njmon_secret": "ignore","data_inject": false,"data_json": true,"directory": "/home/data","influx_host": "localhost","influx_port": 8086,"influx_user": "admin","influx_password": ""njmon","workers": 2,"debug": true,# for njmon2influx.py"batch": 100}
