Checklist Coverage (docs-authoring.md)
- Frontmatter:

Open Questions
- The sample date
2024-20-06was present in the original doc. This is a good rewrite opportunity to fix it.
Onboarding Label
Onboarding label: skipped — This PR edits an existing doc (file status: modified), not a new ingestion guide.
Overall this is a solid rewrite. The doc is much clearer, better structured, and adds valuable content (k8s-infra Helm guidance, logstransform availability warning, troubleshooting section). The only actionable item is fixing the invalid sample dates.

Open Questions
- Is the
logstransformprocessor truly excluded from the SigNoz k8s-infra collector image? If so, the warning should be scoped to k8s-infra specifically, nototelcol-contribin general. - The Vercel build failure should be investigated before merge.
Onboarding Label
Onboarding label: skipped — This PR edits an existing doc (status: modified), not a new ingestion guide.
Overall this is a well-structured rewrite that adds valuable content (k8s-infra Helm guidance, logstransform availability warning, troubleshooting section). Two items need attention before merge: fixing the remaining invalid dates (5 instances) and verifying the logstransform/otelcol-contrib claim.

Pull request overview
Updates the “Parsing Multiline Logs” guide to clarify recommended multiline handling in the OpenTelemetry Collector and to improve the configuration examples (receiver-level multiline, Helm preset usage, and an alternative recombine approach).
Changes:
- Rewrites the doc structure and adds clearer step-by-step guidance for receiver-level
multilineconfiguration (plus k8s-infra Helm preset). - Adds a
logstransform/recombinealternative section with warnings and troubleshooting/validation guidance. - Updates frontmatter metadata (date, description,
doc_type) and refreshes examples/screenshots context.

The sample log entry uses an invalid date format (2024-20-06 has month 20). This can confuse readers and undermines the ^\d{4}-\d{2}-\d{2} start-pattern example; please correct it to a valid, consistent date (e.g., 2024-06-20).

This example line has an invalid date (2024-20-06). Please update it (and the other repeated samples) to a valid, consistent date so the multiline pattern example is realistic.

This sample log line uses an invalid date (2024-20-06). Please correct it to a valid date and keep it consistent across all examples in this doc.
| The `logstransform` processor has development stability and is **not included in the official | ||

The warning states logstransform is not included in the official otelcol-contrib distribution, but other SigNoz docs in this repo configure processors: logstransform: (e.g. data/docs/userguide/fluentbit_to_signoz.mdx, fluentd_to_signoz.mdx, logs_fields.mdx). Please clarify the scope (k8s-infra chart vs other SigNoz collector deployments) and align this statement with the rest of the documentation.

P2 — Invalid sample date still present: 2024-20-06 (month 20)
The previous review flagged this across all log blocks. Line 23 was fixed to 2024-06-20, but 5 remaining instances were missed. Month 20 is not a valid calendar date and undermines the example's credibility.
Remaining instances: lines 28, 49, 54, 132, 137.

| 1. **At the receiver** — use the `multiline` configuration on the filelog receiver (recommended for all setups). | ||
| 2. **At the processor** — use the `recombine` operator in a `logstransform` processor (requires a custom OTel Collector build; not available in `otelcol-contrib` or the k8s-infra chart). |

P2 — Likely incorrect: logstransform processor IS included in otelcol-contrib
The logstransformprocessor exists in the opentelemetry-collector-contrib repo and is included in the default otelcol-contrib distribution. The claim that it's "not included in the official otelcol-contrib distribution" appears inaccurate — it has "development" stability but is still bundled.
The k8s-infra Helm chart claim may be correct if SigNoz uses a custom collector image that excludes it, but that should be stated separately from the otelcol-contrib claim.
Suggested rewording for lines 15–16 and lines 121–124: clarify that logstransform is available in otelcol-contrib but not in the SigNoz k8s-infra chart's collector image.
