Problem

Hi, first, thank you for your work on vector :)

I have a problem with vector 0.37.1 (debian package, but I can trigger the problem with 0.36 too), with vector validate getting stuck majority of the time.
It seems to be related to a kafka source and a elasticsearch sink. If I test other configurations, no problem so far. This may be related to discussions in issue #19333

A minimal configuration which trigger the problem is attached.

11:47:55 [email protected]:/etc/vector# vector validate
√ Loaded ["/etc/vector/vector.yaml"]
√ Component configuration
√ Health check "es" <--- # stuck indefinitely
^C^Z <--- # no way to ctrl+c/stop, only kill -9 works
[2]+  Stopped                 vector validate

Sometimes it works:

11:47:57 [email protected]:/etc/vector# vector validate
√ Loaded ["/etc/vector/vector.yaml"]
√ Component configuration
√ Health check "es"
------------------------------------
                           Validated

I can see an open kafka connection to port 9092 when the validate is stuck.
The offset=Invalid metadata="" in DEBUG is strange. The kafka cluster works correctly.

Thank you,

A trace when validate works (once in a while, random behavior), we can see that everything is fine on rdkafka side 🤔

I'm a bit speechless.
I can't really reproduce the problem on another setup.
After investigation, I decided to add latency on the network interface, because intuition
We have 0.2ms between vector and our source and sink (yes, good network)

Adding 15ms on vector:

tc qdisc add dev ens192  root netem delay 15ms

And, magic, vector validate works all time. This is, wow. If I remove the delay, it's stuck again.

Can somebody with the problem try this workaround ? 🙏

Huh, now that is is strange. Are Kafka and Elasticsearch already up and running when Vector starts up?

Yes they are up during validate, and during starts up.

vector validate also test the sources, even if there is no output in the console about that.

Note: If I run vector, everything is OK, it consumes kafka and write to ES.
