Re: Using latency markers

Hi, Thanks for your answer. But now we get NaN in the 'Task Metrics' in the Web UI. And there's no metric for latency when we attempted to export the metrics through Prometheus either. Then, we attempted to export the metrics through slf4j, I found that it works. One of the logs is as follows:

Re: Using latency markers

Hi, I think FLINK-7692 won't solve this problem. It is just a new feature to provide more functionality for user to use metric system. Regards, Tony Wei 2017-12-26 18:23 GMT+08:00 Marvin777 : > Hi, > > I just want to say we're having the same issues. Using latency markers >

Re: Using latency markers

Hi all! I'm having the same issues. I get NaN in the Task metrics. The version is 1.3.1. Maybe I'm completely missing something... There are questions about FLINK-7692, it can Solve the problem above? What should I do in my version. Thanks! 2017-10-11 23:30 GMT+08:00 Aljoscha Krettek : > This

Any follow-up on this? Jira? PR? On Wed, Sep 13, 2017 at 11:30 AM, Tzu-Li (Gordon) Tai wrote: > Hi Aitozi, > > Yes, I think we haven’t really pin-pointed out the actual cause of the > problem, but if you have a fix for that and can provide a PR we can > definitely look at it! That would be helpf

Re: Using latency markers

Hi Aitozi, Yes, I think we haven’t really pin-pointed out the actual cause of the problem, but if you have a fix for that and can provide a PR we can definitely look at it! That would be helpful. Before opening a PR, also make sure to first open a JIRA for the issue (I don’t think there is one

Re: Using latency markers

Hi, Aljoscha, the dashboard shown NAN is just because the value of the latencyGague is not numerical， so it can't be shown in dashboard, i removed the other latencydescprition except the sink, so i can see the latency in dashboard, do i need to post a pr? thanks, Aitozi -- Sent from: http://ap

Re: Using latency markers

Ok, I can also confirm that it doesn't work. I'll look into this and will let you know what I find. Best, Aljoscha > On 11. Aug 2017, at 14:57, Kien Truong wrote: > > Yes, we also tried changing the tracking interval to no avail, still no > latency metric. > Kien > > On 8/11/2017 7:26 PM, Gy

Re: Using latency markers

Yes, we also tried changing the tracking interval to no avail, still no latency metric. Kien On 8/11/2017 7:26 PM, Gyula Fóra wrote: Yes, they are enabled by default I think. Gyula On Fri, Aug 11, 2017, 14:14 Aljoscha Krettek > wrote: It seems you have to

Yes, they are enabled by default I think. Gyula On Fri, Aug 11, 2017, 14:14 Aljoscha Krettek wrote: > It seems you have to enable latency tracking > via ExecutionConfig.setLatencyTrackingInterval(...). This will make the > sources emit latency tokens, which then in turn update the latency metri

Re: Using latency markers

It seems you have to enable latency tracking via ExecutionConfig.setLatencyTrackingInterval(...). This will make the sources emit latency tokens, which then in turn update the latency metric: https://ci.apache.org/projects/flink/flink-docs-release-1.3/monitoring/metrics.html#latency-tracking <

Re: Using latency markers

Hi, I just want to say we're having the same issues. There's no metric for latency when we attempted to export the metrics through graphite either. Regards, Kien On 8/10/2017 7:36 PM, Aljoscha Krettek wrote: Hi, I must admit that I've never used this but I'll try and look into it. Best
