Description

Probe HTTP endpoints every 5 minutes, store time-series data in Postgres, and generate weekly uptime and latency reports. Has two independent paths: the probe path runs on a 5-minute cron schedule, while the report path is triggered manually for weekly summaries.

DAG Structure

Probe path (every 5 minutes):
probe-endpoints → store-results → alert-failures

Report path (manual):
aggregate-weekly → generate-report → publish-report

Node	Purpose
`probe-endpoints`	HTTP probe of configured endpoints with latency measurement
`store-results`	Store probe results as time-series data in Postgres
`alert-failures`	Send Slack alerts for failed probes or high latency
`aggregate-weekly`	Aggregate time-series data into weekly statistics
`generate-report`	Generate uptime and latency report with AI summary
`publish-report`	Store report in S3 and deliver via Slack

Triggers

manual
cron — every 5 minutes (*/5 * * * *)

Service	Type	Required
Anthropic API	External	Yes (report generation)

tentacular-postgres	Exoskeleton	Yes
tentacular-rustfs	Exoskeleton	Yes
Probe targets (monitored endpoints)	Dynamic	Yes

Config

Key	Default	Description
`timeout`	`60s`	Per-node timeout
`retries`	`1`	Retry count per node
`latency_threshold_ms`	`2000`	Latency threshold for alerts (ms)
`endpoints`	(example list)	List of endpoints with URL and expected body

Secrets

anthropic.api_key — Claude API key for report generation
slack.webhook_url — Slack webhook for alerts and reports
