I was wondering about the update interval with the vault agent on linux.

I am new to vault so I am not fully versed with the inner workings.

What i am trying to achieve is a 30 second interval check for changes. I tried uploading the secrets with a TTl of default\_ttl=“30s” max\_ttl=“30m” to force a check-in. i tried the shell ENV vairable VAULT\_AGENT\_CACHE\_TTL=“30s” and i tried:

```auto
cache {
  use_auto_auth_token = true
  cache_file = "/vault/.vault-token"
  cache_ttl = "30s" # Check every 30 seconds for updates
}

```

But none of those options make the agent check in faster- still seems it checks in randomly between 1 min and 1 hr.

What am i doing wrong?
