feat(landing): guide intros, why it matters and key takeaways - #2023
Rewrites the opening of nine published guides so a first-time reader knows what the topic is, why it matters and what the guide covers before the first section, and adds a Key takeaways box under each intro.
Each intro goes problem → plain definition of the tool or concept → why it matters → what you'll have at the end. The old definition boxes are folded into it.
Small additions, kept short:
Prometheus: a four-line "Which type should I use?" list
Python logging levels: force=True in the basicConfig callout
Pino: Pino's own published benchmark against Winston, linked
Log parsing: a log parsing tools table (Collector, Fluent Bit, Logstash, Vector, Graylog, Splunk), facts from each vendor's page; the mistakes section is now "best practices and common mistakes"
Sentry: a Discounts section (annual billing, sponsored plans, startup program), each checked on sentry.io
New Relic: FAQs "Why is New Relic expensive?" and "Are there hidden costs?"
Landing build passes; rendered pages checked with Playwright.

rotation and retention as controls on log growth, without promising they prevent

- Line 433: Update the production-sinks guidance in the Loguru guide to address
the default stderr sink as well: tell readers to remove and replace it with

before importing Loguru.
Review comments at @apps/landing/src/pages/guides/pino-logger.astro:
- Line 413: Update the OpenTelemetry Pino instrumentation takeaway to clarify
that a log line carries a trace ID only when written during an active span; do
not imply every line has a trace ID.

- Line 349: Update the Sentry for Startups eligibility text in the list item to
specify that the $5 million funding limit applies to venture capital, not all
sources of funding.

dropped only after that category’s included or reserved volume and the shared
budget are both exhausted; preserve the existing billing-cycle reset detail.

Walkthrough
Nine landing-page guides add introductory leads and key takeaways. Several also add guide-specific pricing, logging, incident-response, or metrics content. The pages replace introductory answer panels and their styling with takeaways panels.
Each guide adds or revises its introduction and takeaways. The pages remove introductory answer panels and update their local styles for the new takeaways panels.
Guide-specific sections and details apps/landing/src/pages/guides/log-parsing.astro, apps/landing/src/pages/guides/new-relic-pricing.astro, apps/landing/src/pages/guides/pino-logger.astro, apps/landing/src/pages/guides/prometheus-metrics.astro, apps/landing/src/pages/guides/python-logging-levels.astro, apps/landing/src/pages/guides/sentry-pricing.astro
Log parsing adds a comparison of six tools. The New Relic and Sentry guides add pricing details. The Pino guide adds a benchmark result, the Prometheus guide adds metric-type guidance, and the Python logging guide adds a configuration option.
These guides are public documentation, and a few takeaways could mislead readers. Following them could expose sensitive data in logs or silently stop telemetry export. Several other statements overstate what the tools do. Correct the flagged guidance before merge. The pages themselves should render and build normally.

Sanitize raw records before exporting them.
This advice sends unmatched lines with their raw bodies. Those bodies can contain query-string tokens or personal data. The nginx configuration also retains the raw body on matched records, even though it excludes the query string from url.path. Sanitize the body before export, while keeping parse failures observable.

Do not promise that retention prevents a full disk.
The example retains rotated files for 14 days. A high log rate can fill the disk before those files expire. Describe rotation and retention as controls on log growth, not a disk-capacity guarantee. (loguru.readthedocs.io)

Disable diagnostics on the default sink too.
Adding a sink with diagnose=False leaves Loguru’s default stderr sink active with diagnostics enabled. An exception can still expose variable values there. Tell readers to remove and replace that sink, or set LOGURU_DIAGNOSE=NO before import. (loguru.readthedocs.io)

Limit trace-ID correlation to active spans.
The instrumentation does not add a trace ID outside an active span. The guide’s startup example at Line 664 confirms this. Qualify the takeaway so readers do not expect a trace link on every line. (github.com)

Warn that force=True removes existing handlers.
If a reader imports this guide’s telemetry.py first, force=True removes its OpenTelemetry handler and stops backend log export. Prefer changing the level when existing handlers must remain, and state the replacement side effect. (docs.python.org)

Qualify the budget cutoff by category.
An exhausted shared budget does not discard data in a category that still has included or reserved volume. The flow at Lines 489–493 shows those volumes are used first. State that data is dropped only after that category’s volume and the budget are exhausted.
