for Vault 1.5.0 compared to 1.4.1. Please read it carefully.
## Raft Configuration
@ -24,3 +24,18 @@ In addition, a new metric has been introduced, `vault.raft-storage.entry_size`,
that allows for operators to sample the entry size, view the average, and adjust
the configuration value as necessary. For additional details, please see
[Raft configuration](docs/configuration/storage/raft).
## Known Issues
Enabling telemetry on 32-bit systems will cause Vault to crash. A workaround for this
issue is to disable collection of usage gauges in the [telemetry](docs/configuration/telemetry) stanza of the configuration.
```
telemetry {
...
usage_gauge_period = "none"
}
```
This will suppress the metrics `vault.identity.entity.count`, `vault.identity.entity.alias.count`, `vault.token.count`, `vault.token.count.by_auth`, `vault.token.count.by_policy`, `vault.token.count.by_ttl` and `vault.secret.kv.count` that were introduced in version 1.5.0, but all other Vault telemetry will remain available.
