From c4da7a7a9d98958e377a5777658c747fff14e0d2 Mon Sep 17 00:00:00 2001 From: Timo Beckers Date: Wed, 20 Apr 2022 09:02:56 +0200 Subject: [PATCH] Downgrade prometheus/client_golang to v1.11.1 This reverts commit d8e3f28c01f04b4c314b65e090a21c2aaf235207. --- See https://github.com/cilium/cilium/issues/19425. Extra Go metrics were added to the Prometheus client, some having NaN values, breaking json marshaling on the server side of `cilium metrics list`: msg="Cilium API handler panicked" panic_message="json: unsupported value: NaN" url=/v1/metrics/ ...
