Subject [jira] [Commented] (FLINK-11742) Push metrics to Pushgateway without "instance"
Date Sun, 03 Mar 2019 05:02:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-11742?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16782592#comment-16782592
] 

Tom Goong commented on FLINK-11742:
-----------------------------------

I need to monitor some conditions of different taskmanagers. But if there is no given instance
or the correct distinction between different taximanagers, putgateway will be treated as one,
resulting in data loss and line discontinuity.

> [https://github.com/prometheus/pushgateway]
> when sending a metric to Prometheus Pushgateway, you need to give an "instance" message.
>  In actual use, after there is no "instance", Prometheus stores metrics with problems,
metrics are not continuous, and a lot of data is lost. After adding instance, it returns to
normal.
