关于InfluxDB中大量监控指标的count为0
Hi! 我最近在为Flink集群搭建监控，使用了InfluxDB+Grafana。在关注每秒同步行数以及每秒同步数据大小时，我使用了以下相关指标： taskmanager_job_task_numRecordsIn、taskmanager_job_task_Shuffle_Netty_Input_numBytesInLocalPerSecond 让我感到的奇怪的是，当我去查询InfluxDB时，指标的count都为空 > select * from > taskmanager_job_task_Shuffle_Netty_Input_numBytesInLocalPerSecond where > count != 0; > > select * from taskmanager_job_task_numRecordsIn where count != 0; 所有指标的count都是空的 > select count(*) from taskmanager_job_task_numRecordsIn where count = 0; name: taskmanager_job_task_numRecordsIn time count_count --- 0325289 > select count(*) from > taskmanager_job_task_Shuffle_Netty_Input_numBytesInLocalPerSecond where > count = 0; name: taskmanager_job_task_Shuffle_Netty_Input_numBytesInLocalPerSecond time count_count count_rate --- -- 0325328 325328 请问这是正常现象吗？如果这是正常的，我该如何在界面上展示我的同步行数/s以及同步大小/s？因为现在展示出来都是一条线，即为0 [image: image.png] [image: image.png]
Can i contribute for flink doc ?
Hi, all I'm a Flink user. recently I find some problems when I use Flink, it takes some time to understand the internal mechanisms. This really makes me know more about Flink, but I think the doc can be clearer, so I open some merge requests for the doc: - https://github.com/apache/flink/pull/16823 - https://github.com/apache/flink/pull/16683 but I don't know why nobody merges it and no comment.
