Hello, everyone, I used to connect redis logstash, and monitor the redis for the key, not the beginning of any problems, but after a very long period of time will be reported redis connection timeout error. Is this a warning? What is the problem? Is the middle of a moment logstash and redis interrupted? So if interrupted, logstash will often try to reconnect redis? But it does not seem to break, because I can get to the log changes. Error log is as follows:
