postgres.auth was running an `unless` shell check per up-minion on every
manager highstate, even when nothing had changed — N fork+python starts
of so-yaml.py add up on large grids. The work is only needed when a
specific minion's key is accepted.
- salt/postgres/auth.sls: fan out only when postgres_fanout_minion
pillar is set (targets that single minion). Manager highstates with
no pillar take a zero-N code path.
- salt/reactor/telegraf_user_sync.sls: re-pass the accepted minion id
as postgres_fanout_minion to the orch.
- salt/orch/telegraf_postgres_sync.sls: forward the pillar to the
salt.state invocation so the state render sees it.
- salt/manager/tools/sbin/soup: for the one-time 3.1.0 backfill, drop
the per-minion state.apply and do an in-shell loop over the minion
pillar files using so-yaml.py directly. Skips minions that already
have postgres.telegraf.user set.
New minions run highstate as part of onboarding, which already applies
the telegraf state with the fresh pillar entry we just wrote. Pushing
telegraf a second time from the reactor is redundant.
- Remove the MINION-scoped salt.state block from the orch; keep only
the manager-side postgres.auth + postgres.telegraf_users provisioning.
- Stop passing minion_id as pillar in the reactor; the orch doesn't
reference it anymore.
salt/auth fires on every minion authentication — including every minion
restart and every master restart — so the reactor was re-running the
postgres.auth + postgres.telegraf_users + telegraf orchestration for
every already-accepted minion on every reconnect. The underlying states
are idempotent, so this was wasted work and log noise, not a correctness
issue.
Switch the subscription to salt/key, which fires only when the master
actually changes a key's state (accept / reject / delete). Match the
pattern used by salt/reactor/check_hypervisor.sls (registered in
salt/salt/cloud/reactor_config_hypervisor.sls) and add the result==True
guard so half-failed key operations don't trigger the orchestration.
Introduces global.telegraf_output (INFLUXDB|POSTGRES|BOTH, default BOTH)
so Telegraf can write metrics to Postgres alongside or instead of
InfluxDB. Each minion authenticates with its own so_telegraf_<minion>
role and writes to a matching schema inside a shared so_telegraf
database, keeping blast radius per-credential to that minion's data.
- Per-minion credentials auto-generated and persisted in postgres/auth.sls
- postgres/telegraf_users.sls reconciles roles/schemas on every apply
- Firewall opens 5432 only to minion hostgroups when Postgres output is active
- Reactor on salt/auth + orch/telegraf_postgres_sync.sls provision new
minions automatically on key accept
- soup post_to_3.1.0 backfills users for existing minions on upgrade
- so-show-stats prints latest CPU/mem/disk/load per minion for sanity checks
- so-telegraf-trim + nightly cron prune rows older than
postgres.telegraf.retention_days (default 14)
