Umami Analytics

Fetch traffic summaries and analytics data from an Umami instance.

Configuration

Set these environment variables before running:

Variable	Required	Description
`UMAMI_API_URL`	Yes	Base URL of your Umami instance (e.g. `https://cloud.umami.is` )
`UMAMI_API_KEY`	One of these	API key for Umami Cloud. Used as Bearer token directly.
`UMAMI_USERNAME`	One of these	Username for self-hosted login via `/api/auth/login` .
`UMAMI_PASSWORD`	With username	Password for self-hosted login.

If

UMAMI_API_KEY

is set, it takes precedence over username/password.

Workflow: Daily Traffic Summary

Run the script:

bash

bash ~/Projects/skills/umami/scripts/umami-summary.sh

Parse the JSON output.
Format as a markdown table:

Website	Domain	Pageviews	Visitors	Visits	Bounces	Avg Time	Active
My Blog	blog.example.com	1,234 (980)	567 (510)	890 (801)	123 (110)	45s (38s)	3
Totals		1,234 (980)	567 (510)	890 (801)	123 (110)	45s (38s)	3

Show previous period values in parentheses after each metric (e.g. "1,234 (980)" means 1,234 current, 980 previous).
Format numbers with commas for readability.
Convert
```
totaltime
```
to human-readable duration (e.g. "1m 23s").
Calculate average time as
```
totaltime / visits
```
for each site, using
```
prev_totaltime / prev_visits
```
for the previous period.
Bold the totals row.

Workflow: Active Users Only

For "who is on my site right now?" queries, use the lightweight flag:

bash

bash ~/Projects/skills/umami/scripts/umami-summary.sh --active-only

This skips the stats API calls and only fetches current active visitor counts. Format as a simpler table:

Website	Domain	Active
My Blog	blog.example.com	3

Error Handling

The script exits non-zero and writes JSON to stderr on failure:

Missing env vars:
```
{"error": "UMAMI_API_URL is not set"}
```

Auth failure:

{"error": "Authentication failed (HTTP 401)"}

Unreachable server:

{"error": "Could not connect to https://..."}

Report these errors clearly to the user with the specific message. Suggest checking their environment variables.
