Prometheus retention_time not applied to vault_route_* metrics

Vault
1

Hi team, I’m testing OpenBao’s Prometheus metrics retention and noticed something odd.
My config include:

telemetry {
prometheus_retention_time = “24h”
disable_hostname = true
usage_gauge_period = “20s”
}

i have a ns called custone ,so i I expected metrics like vault_route_read_custone_kv__count to remain visible for at least 24 hours after last activity. But in practice, the counter disappears within 1–2 minutes if there’s no traffic, even though I set prometheus_retention_time = "24h".

Hi @praneethpottimuthi, this is a forum specifically for HashiCorp Vault. OpenBao is now its own project with its own implementation, so you will need to direct OpenBao-related questions to their community forums or issue tracking system. Thanks very much for your interest! If you have Vault-specific questions, please do use this forum to ask them!
