Christian, Thanks for your response! After a second look, the perceived bug was actually a combination of two non-Prometheus issues:
- Other firewall rules were preventing connections to port 9090. - I misread netstat's output- Prometheus was binding to port 9090 for all IPv6 addresses and _implicitly_ binding in IPV4 (this binding isn't printed in netstat!) Hope you and yours are well, John On Wednesday, August 5, 2020 at 6:23:03 AM UTC-4, Christian Hoffmann wrote: > > Hi, > > On 8/4/20 3:23 PM, jumble wrote: > > Latest prometheus, on RHEL8. > > > > Observed behavior: bound to |127.0.0.1:9090| > > This sounds unexpected.
