hi,

im trying to find a way to access response headers in order to log the server ip, which can be one of all cluster's servers

Hey @liorg2, good question; the response headers indeed aren't exposed right now.

We can look into ways of exposing them, but in the meantime, can you describe your setup a bit? E.g. are you using a load balancer in front of your cluster? HAProxy? If not, who is adding the IP address as a header on the response? (Neo4j doesn't natively, I don't believe.)

thanks for answering so quickly! i'm using HAProxy to set the header

aseemk commented 8 years ago

The good news, then, is that you can include the IP address in your HAProxy logs!

We log a bunch of things like this in our HAProxy logs:

Web server IP address
"Pool" (write or read)
Neo4j server (we use hostname instead of IP address for easier consumption)
Custom headers like short query name
