ccusage-fleet

Run ccusage on local and SSH-connected machines, then aggregate daily, weekly, or monthly usage reports into one view.

npx ccusage-fleet daily --hosts localhost,rtzr,jiun-mbp,jiun-mini

ccusage-fleet executes ccusage independently on every host and transfers only aggregated JSON over SSH. Claude, Codex, OpenCode, and the other agents supported by ccusage are detected on each machine without copying raw conversation transcripts.

Requirements

• Node.js 20 or newer on the machine running ccusage-fleet
• Node.js and npx on SSH hosts (login-shell version managers such as nvm and fnm are supported)
• Key-based SSH access configured through ~/.ssh/config

SSH runs with BatchMode=yes, so ccusage-fleet never opens an interactive password prompt.

Usage

# Local machine and three SSH aliases
npx ccusage-fleet daily --hosts localhost,rtzr,jiun-mbp,jiun-mini

# Machine-readable output
npx ccusage-fleet daily --hosts localhost,rtzr --json

# Weekly and monthly reports use the same options
npx ccusage-fleet weekly --hosts localhost,rtzr --group-by agent
npx ccusage-fleet monthly --hosts localhost,rtzr --group-by device

# Default: date -> agent -> models
npx ccusage-fleet daily --hosts localhost,rtzr --group-by agent

# Date -> device -> models
npx ccusage-fleet daily --hosts localhost,rtzr --group-by device

# Date totals only
npx ccusage-fleet daily --hosts localhost,rtzr --group-by none

# Append a report-bucket token distribution graph
npx ccusage-fleet daily --hosts localhost,rtzr --graph

# Scale the graph by estimated cost
npx ccusage-fleet daily --hosts localhost,rtzr --graph --graph-metric cost

# One consistent date range and timezone on every device
npx ccusage-fleet daily \
  --hosts localhost,rtzr \
  --since 2026-07-01 \
  --until 2026-07-15 \
  --timezone Asia/Seoul

# Environment variable
CCUSAGE_FLEET_HOSTS=localhost,rtzr npx ccusage-fleet daily

Run npx ccusage-fleet --help for all options.

Configuration

Create ccusage-fleet.config.json, .ccusage-fleet.json, or ~/.config/ccusage-fleet/config.json:

{
  "$schema": "https://raw.githubusercontent.com/open330/ccusage-fleet/main/ccusage-fleet.schema.json",
  "hosts": [
    { "name": "localhost", "type": "local" },
    { "name": "rtzr", "type": "ssh", "target": "rtzr" },
    { "name": "jiun-mbp", "type": "ssh", "target": "jiun-mbp" },
    { "name": "jiun-mini", "type": "ssh", "target": "jiun-mini" }
  ],
  "timezone": "Asia/Seoul",
  "groupBy": "agent",
  "graph": false,
  "graphMetric": "tokens",
  "concurrency": 4,
  "timeoutMs": 120000
}

Named entries let the displayed device name differ from its SSH target:

{ "name": "workstation", "type": "ssh", "target": "user@server.example" }

Command-line hosts override configured hosts. Repeated --host options are also supported.

Grouping

The default table follows ccusage's report shape: one All row per date, followed by agent rows and their models, and a final Total row.

Option	Detail rows
--group-by agent	Claude, Codex, and other detected agents aggregated across devices
--group-by device	One row per local or SSH device
--group-by none	Date totals without detail rows

The former --by-host and --no-by-host options remain as aliases for --group-by device and --group-by none. Set CCUSAGE_FLEET_GROUP_BY to choose a default without a config file.

Graph

Add --graph to append a proportional distribution chart after the table. Bars use total tokens by default; choose --graph-metric cost to scale them by estimated cost. Buckets follow the report command: days for daily, weeks for weekly, and months for monthly.

Hour buckets will require a future normalized event export from ccusage; ccusage-fleet does not copy raw transcripts to approximate them.

Failure handling

By default, reachable hosts are reported even when another host fails. Add --strict to return a non-zero exit status if any host fails. --timeout is applied per host.

Privacy and correctness

Raw agent logs stay on their original machines; only ccusage's aggregated JSON is transferred. This protects prompt and response content and keeps network traffic small.

Because aggregation happens after each machine has produced a summary, identical transcripts copied between machines cannot be deduplicated across hosts. Do not sync the same agent log directory to multiple fleet members unless you intentionally want both copies counted.
