Usage

• cd tcp_port_exporter/v1
• Create a check_tcp_port.list file if not exists; add the targets like this format hostname--192.168.111.111:9100 what u want to monitor;
• Run nohup python ./tcp_port_exporter.py >> ./tcp_port_exporter.log 2>&1 &
• Go to http://your_ip:1990/metrics to see metrics

Alternatively, if you don't wish to install the package, run using $ vmware_exporter/vmware_exporter.py

Configuration

add the following config parameters to prometheus.yml:

   - job_name: 'tcp_port_exporter'
    metrics_path: /metrics
    scrape_interval: 60s
    file_sd_configs:
      - files: ['/path/to/file/check_tcp_port.json']

the check_tcp_port.json is like that:

[
    {
        "targets": [
            "your_ip:1990"
        ],
        "labels": {}
    }
]

Metrics

# HELP check_tcp_port # 端口存活监测
# TYPE check_tcp_port gauge
check_tcp_port{host="192.168.111.111",port="9100"} 1.0

• formatters
  定义日志输出的具体格式
• handlers
  定义如何处理日志，比如发送到文件，console等
• filters
  定义一个日志记录是否发送到handler
• loggers
  记录日志接口，供代码使用

How to use logging

import logging

# logger = logging.getLogger(str('mylogger'))
logger = logging.getLogger(__name__)  # 用__name__通用,自动检测

def test():
	logger.debug()
	logger.info()
	logger.warning()
	logger.error()
	logger.critical()
