The Telegraf backend selector lived at global.telegraf_output but it is
a Telegraf-scoped setting, not a cross-cutting grid global. Move both
the value and the UI annotation under the telegraf pillar so it shows
up alongside the other Telegraf tuning knobs in the Configuration UI.
- salt/telegraf/defaults.yaml: add telegraf.output: BOTH
- salt/telegraf/soc_telegraf.yaml: add telegraf.output annotation
- salt/global/defaults.yaml: remove global.telegraf_output
- salt/global/soc_global.yaml: remove global.telegraf_output annotation
- salt/vars/globals.map.jinja: drop telegraf_output from GLOBALS
- salt/firewall/map.jinja: read via pillar.get('telegraf:output')
- salt/postgres/telegraf_users.sls: read via pillar.get('telegraf:output')
- salt/telegraf/etc/telegraf.conf: read via TELEGRAFMERGED.output
- salt/postgres/tools/sbin/so-stats-show: update user-facing docs
No behavioral change — default stays BOTH.
High-cardinality inputs (docker, procstat, kafka) trigger ALTER TABLE
ADD COLUMN on every new field name, and with all minions writing into
a shared 'telegraf' schema the metric tables hit Postgres's 1600-column
per-table ceiling quickly. Setting fields_as_jsonb and tags_as_jsonb on
the postgresql output keeps metric tables fixed at (time, tag_id,
fields jsonb) and tag tables at (tag_id, tags jsonb).
- so-stats-show rewritten to use JSONB accessors
((fields->>'x')::numeric, tags->>'host', etc.) and cast memory/disk
sizes to bigint so pg_size_pretty works
- Drop regex/regexFailureMessage from telegraf_output SOC UI entry to
match the convention upstream used when removing them from
mdengine/pcapengine/pipeline; options: list drives validation
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)
