flask - exporter -gauge - python - 请求时间显示 + 自定义监控-pushgateway-flask
1.显示请求使用时间-使用gauge显示每次的请求时间
[root@VM_0_111_centos exporters]# cat request_time.py |egrep -v '^#|^$' import prometheus_client from prometheus_client import Counter, Gauge from prometheus_client.core import CollectorRegistry from flask import Response, Flask import pycurl app = Flask(__name__) REGISTRY = CollectorRegistry(auto_describe=False) http_request_time = Gauge( "myhttp_request_time", "use gauge to demostrate how muny time the request.", registry=REGISTRY) @app.route('/metrics') def r_value(): c = pycurl.Curl() c.setopt(c.URL, '10.0.0.111:55555/a.txt') c.setopt(c.CONNECTTIMEOUT, 3) c.setopt(c.TIMEOUT, 3) try: c.perform() except pycurl.error: http_code = 500 http_total_time = 999 else: http_code = c.getinfo(pycurl.HTTP_CODE) http_total_time = c.getinfo(pycurl.TOTAL_TIME) http_request_time.set(http_total_time) return Response(prometheus_client.generate_latest(REGISTRY), mimetype="text/plain") @app.route('/') def index(): return "Hello, Prometheus!" if __name__ == "__main__": app.run(host='0.0.0.0',port='29091',debug=True)

3.以上作用是在本地生成一个小型网站,下一步是将选定的数据发送到pushgateway

用一个例子来演示会更加清晰
