Cronalytics

What Cronalytics does

The plugin hooks into Hermes' on_session_end event, stores derived analytics in a local SQLite fact database, and exposes them through three interfaces: a /cronalytics tab inside the Hermes dashboard with charts and filters, a CLI with eight commands and three global filters for scriptable access, and an agent skill that teaches Hermes to run a structured seven-step diagnostic over the collected data.

That diagnostic walks from time-window verification through baseline comparison, job-level drill-down, per-run investigation, failure-pattern analysis, model-economics review and trend validation, cross-referencing jobs.json and grading every finding HIGH, MEDIUM or LOW confidence with supporting evidence. After install, the plugin needs at least one cron run to capture data automatically, or a manual "Sync Now" backfill from existing session history.

Key features

• Session-level cost and usage attribution for every cron-originated run
• Dashboard tab with charts, cards and filters for cost, pace and failure patterns
• CLI with eight commands, three global filters and JSON output for scripting
• Agent skill running a structured seven-step cron health diagnostic
• Manual Sync Now backfill from existing state.db session history

When to use it

• Seeing which scheduled Hermes jobs are costing the most, by model and by job
• Asking a Hermes agent to flag anything anomalous in the last two weeks of cron runs
• Scripting a daily cost or failure-rate export from the cron fact database

Who it is for: Hermes Agent operators running scheduled cron jobs who want visibility into what those jobs cost and how often they fail.

How it fits with Hermes Agent

Cronalytics is built specifically as a Hermes Agent plugin, hooking into Hermes' own session-end event and reading its cron job and session records directly.
