在守护进程中进行 sentry 上报遇到的问题
问题描述
在一个定时执行的任务中，向 sentry 上报信息：
在主进程中运行没有问题：
import datetime
import os
import sys
import configparser
import logging.config
import time
from importlib import util
from apscheduler.schedulers.blocking import BlockingScheduler
from daemon import Daemon
from raven import Client
from utils import LoggerWriter
sentry = Client("https://[email protected]/1501024")
class MySyncDaemon(Daemon):
def run(self):
sys.stderr = self.log_err
try:
util.find_spec('setproctitle')
self.setproctitle = True
import setproctitle
setproctitle.setproctitle('calendar')
except ImportError:
self.setproctitle = False
# 设置定时任务的时候首次不会运行
# 所以在开启定时任务之前先执行一次
# try:
# self.dummy_sched()
# except Exception as e:
# self.logger.error(f"定时执行第一次失败，原因是 {e}")
# raise
# 不使用定时任务调度 直接悬挂 5s 执行一次
while True:
t = datetime.datetime.now()
self.logger.info(f"{t} 开始发送消息 ")
sentry.captureMessage(f"{t} 我是一条发送的消息")
self.logger.info(f"{datetime.datetime.now()} 发送消息结束 ")
time.sleep(5)
# try:
# self.scheduler()
# except Exception as e:
# self.logger.info(f"开启定时任务失败，原因是{e}")
# raise
def scheduler(self):
sched = BlockingScheduler()
try:
sched.add_job(self.dummy_sched, 'interval', seconds=5)
sched.start()
except Exception as e:
self.logger.error(f'Cannot start scheduler. Error: {e}')
sys.exit(1)
def dummy_sched(self):
try:
# from raven import Client
# sentry = Client("https://[email protected]/1501024")
t = datetime.datetime.now()
logger.info(f"{t} 开始发送消息 ")
sentry.captureMessage(f"{t} 我是一条发送的消息")
logger.info(f"{time.time()} 发送消息结束 ")
except Exception as e:
self.logger.warning(f"task fail, {e}", exc_info=True)
sys.exit(1)
def write_pid(self, pid):
open(self.pidfile, 'a+').write("{}\n".format(pid))
if __name__ == "__main__":
config = configparser.ConfigParser()
config.read("./logging.conf")
config["handler_timedRotatingFileHandler"]["args"] = str(('./detection.log', 'midnight', 1, 10))
logging.config.fileConfig(config)
logger = logging.getLogger('detection')
pid_file = os.path.join(os.getcwd(), "detection.pid")
log_err = LoggerWriter(logger, logging.ERROR)
detection = MySyncDaemon(pidfile=pid_file, log_err=log_err)
# 跳过守护进程 直接悬挂终端程序运行
detection.run()
# if len(sys.argv) >= 2:
# if 'start' == sys.argv[1]:
# detection.start()
# elif 'stop' == sys.argv[1]:
# detection.stop()
# elif 'restart' == sys.argv[1]:
# detection.restart()
# elif 'status' == sys.argv[1]:
# detection.status()
# else:
# sys.stderr.write("Unknown command\n")
# sys.exit(2)
# sys.exit(0)
# else:
# sys.stderr.write("usage: %s start|stop|restart\n" % sys.argv[0])
# sys.exit(2)
其次，在守护进程中可执行任务：
import datetime
import os
import sys
import configparser
import logging.config
import time
from importlib import util
from apscheduler.schedulers.blocking import BlockingScheduler
from daemon import Daemon
from raven import Client
from utils import LoggerWriter
sentry = Client("https://[email protected]/1501024")
class MySyncDaemon(Daemon):
def run(self):
sys.stderr = self.log_err
try:
util.find_spec('setproctitle')
self.setproctitle = True
import setproctitle
setproctitle.setproctitle('calendar')
except ImportError:
self.setproctitle = False
# 设置定时任务的时候首次不会运行
# 所以在开启定时任务之前先执行一次
# try:
# self.dummy_sched()
# except Exception as e:
# self.logger.error(f"定时执行第一次失败，原因是 {e}")
# raise
# 不使用定时任务调度 直接悬挂 5s 执行一次
while True:
t = datetime.datetime.now()
self.logger.info(f"{t} 开始发送消息 ")
# sentry.captureMessage(f"{t} 我是一条发送的消息")
self.logger.info(f"{datetime.datetime.now()} 发送消息结束 ")
time.sleep(5)
# try:
# self.scheduler()
# except Exception as e:
# self.logger.info(f"开启定时任务失败，原因是{e}")
# raise
def scheduler(self):
sched = BlockingScheduler()
try:
sched.add_job(self.dummy_sched, 'interval', seconds=5)
sched.start()
except Exception as e:
self.logger.error(f'Cannot start scheduler. Error: {e}')
sys.exit(1)
def dummy_sched(self):
try:
# from raven import Client
# sentry = Client("https://[email protected]/1501024")
t = datetime.datetime.now()
logger.info(f"{t} 开始发送消息 ")
sentry.captureMessage(f"{t} 我是一条发送的消息")
logger.info(f"{time.time()} 发送消息结束 ")
except Exception as e:
self.logger.warning(f"task fail, {e}", exc_info=True)
sys.exit(1)
def write_pid(self, pid):
open(self.pidfile, 'a+').write("{}\n".format(pid))
if __name__ == "__main__":
config = configparser.ConfigParser()
config.read("./logging.conf")
config["handler_timedRotatingFileHandler"]["args"] = str(('./detection.log', 'midnight', 1, 10))
logging.config.fileConfig(config)
logger = logging.getLogger('detection')
pid_file = os.path.join(os.getcwd(), "detection.pid")
log_err = LoggerWriter(logger, logging.ERROR)
detection = MySyncDaemon(pidfile=pid_file, log_err=log_err)
# 跳过守护进程 直接悬挂终端程序运行
# detection.run()
if len(sys.argv) >= 2:
if 'start' == sys.argv[1]:
detection.start()
elif 'stop' == sys.argv[1]:
detection.stop()
elif 'restart' == sys.argv[1]:
detection.restart()
elif 'status' == sys.argv[1]:
detection.status()
else:
sys.stderr.write("Unknown command\n")
sys.exit(2)
sys.exit(0)
else:
sys.stderr.write("usage: %s start|stop|restart\n" % sys.argv[0])
sys.exit(2)
但是，当守护进程和sentry上报一起使用的时候，就会出现阻塞的情况：
代码：
import datetime
import os
import sys
import configparser
import logging.config
import time
from importlib import util
from apscheduler.schedulers.blocking import BlockingScheduler
from daemon import Daemon
from raven import Client
from utils import LoggerWriter
sentry = Client("https://[email protected]/1501024")
class MySyncDaemon(Daemon):
def run(self):
sys.stderr = self.log_err
try:
util.find_spec('setproctitle')
self.setproctitle = True
import setproctitle
setproctitle.setproctitle('calendar')
except ImportError:
self.setproctitle = False
# 设置定时任务的时候首次不会运行
# 所以在开启定时任务之前先执行一次
# try:
# self.dummy_sched()
# except Exception as e:
# self.logger.error(f"定时执行第一次失败，原因是 {e}")
# raise
# 不使用定时任务调度 直接悬挂 5s 执行一次
while True:
t = datetime.datetime.now()
self.logger.info(f"{t} 开始发送消息 ")
sentry.captureMessage(f"{t} 我是一条发送的消息")
self.logger.info(f"{datetime.datetime.now()} 发送消息结束 ")
time.sleep(5)
# try:
# self.scheduler()
# except Exception as e:
# self.logger.info(f"开启定时任务失败，原因是{e}")
# raise
def scheduler(self):
sched = BlockingScheduler()
try:
sched.add_job(self.dummy_sched, 'interval', seconds=5)
sched.start()
except Exception as e:
self.logger.error(f'Cannot start scheduler. Error: {e}')
sys.exit(1)
def dummy_sched(self):
try:
# from raven import Client
# sentry = Client("https://[email protected]/1501024")
t = datetime.datetime.now()
logger.info(f"{t} 开始发送消息 ")
sentry.captureMessage(f"{t} 我是一条发送的消息")
logger.info(f"{time.time()} 发送消息结束 ")
except Exception as e:
self.logger.warning(f"task fail, {e}", exc_info=True)
sys.exit(1)
def write_pid(self, pid):
open(self.pidfile, 'a+').write("{}\n".format(pid))
if __name__ == "__main__":
config = configparser.ConfigParser()
config.read("./logging.conf")
config["handler_timedRotatingFileHandler"]["args"] = str(('./detection.log', 'midnight', 1, 10))
logging.config.fileConfig(config)
logger = logging.getLogger('detection')
pid_file = os.path.join(os.getcwd(), "detection.pid")
log_err = LoggerWriter(logger, logging.ERROR)
detection = MySyncDaemon(pidfile=pid_file, log_err=log_err)
# 跳过守护进程 直接悬挂终端程序运行
# detection.run()
if len(sys.argv) >= 2:
if 'start' == sys.argv[1]:
detection.start()
elif 'stop' == sys.argv[1]:
detection.stop()
elif 'restart' == sys.argv[1]:
detection.restart()
elif 'status' == sys.argv[1]:
detection.status()
else:
sys.stderr.write("Unknown command\n")
sys.exit(2)
sys.exit(0)
else:
sys.stderr.write("usage: %s start|stop|restart\n" % sys.argv[0])
sys.exit(2)
日志显示执行一次任务之后程序被阻塞，而且在 sentry 中没有收到这一条消息。
感觉问题可能是出在 sentry 不接受守护进程发送的消息。
