Re: Flink 1.14 metrics : taskmanager host name missing
There is unfortunately no knob for you to turn to get the previous behavior. The host variable has a number of issues (being inconsistent across processes, not being configurable, not being stable (because we just forward what we get from the RPC layer)), such that at the moment it probably shouldn't be relied on at all. https://issues.apache.org/jira/browse/FLINK-7198 https://issues.apache.org/jira/browse/FLINK-8358 On 01/02/2022 07:32, Mayur Gubrele wrote: Hi, Can someone please take a look at this?

Flink 1.14 metrics : taskmanager host name missing
Hello, We recently upgraded our Flink cluster to 1.14 and noticed that all the taskmanager metrics we receive in our Prometheus data source get host IPs instead of hostnames, which was the case earlier before we moved to 1.14. I see on the flink dashboard as well under taskmanager details, host IPs are being populated now. This is a breaking change for us. Some of our APIs use this host tag value which used to be the hostname earlier. Can you tell us if there's a way we can configure to get hostnames instead of IPs? Thanks, Mayur
