feat: identify the device with an origin SD-ELEMENT by DavidCozens · Pull Request #59 · cososo-ltd/solid-syslog-example

DavidCozens · 2026-08-16T06:32:36Z

Name the device in the record with SolidSyslogOriginSd — the software, its version, and the
enterprise number.

#define SYSLOG_SOFTWARE   "solid-syslog-example"
#define SYSLOG_SW_VERSION "0.1.0"

struct SolidSyslogOriginSdConfig originConfig = {
    .Software     = SYSLOG_SOFTWARE,
    .SwVersion    = SYSLOG_SW_VERSION,
    .EnterpriseId = SYSLOG_ENTERPRISE_ID,
};
sd[2] = SolidSyslogOriginSd_Create(&originConfig);

... [origin software="solid-syslog-example" swVersion="0.1.0" enterpriseId="32473"] device started

This lands after the store rather than before it. While records went straight out, the answer to
"who sent this" was implied by the connection they arrived on. Once records can replay hours later
that is no longer so, and the record has to carry it.

The ip PARAM is left out here. The address the collector sees is still the address that reached
it; the next stage takes that assumption away.

SYSLOG_ENTERPRISE_ID is defined in its own header rather than beside the element that carries it,
because the number identifies the vendor rather than the logger — anything else this product puts its
own name on wants the same one.

Three elements put the record at 245 octets.

Enterprise number 32473 is reserved for documentation and testing by RFC 5612. A shipping product
uses its own, registered with IANA.

Summary by CodeRabbit

New Features
- Added origin metadata to syslog messages, including device software name, version, and enterprise identifier.
- Syslog output now supports a dedicated Origin structured-data element for device identification.
Documentation
- Updated usage guidance and cost estimates for the Origin stage.
- Clarified when origin metadata is required and how enterprise identifiers are handled.
Tests
- Updated run reports and self-check results to reflect Origin metadata and revised resource measurements.

📝 Walkthrough

Walkthrough

The syslog example replaces the File store stage with an Origin stage. It registers RFC 5424 origin structured data containing software name, version, and enterprise ID. The README and run report now describe and measure the Origin configuration.

Changes

Origin metadata

Layer / File(s)	Summary
Origin configuration `app/syslog/Syslog.c`, `app/syslog/SyslogEnterprise.h`	The logger adds `SolidSyslogOriginSd` with software identity and enterprise ID fields. The structured-data capacity increases from two to three entries.
Origin documentation and measurements `README.md`, `run-report.md`	The documentation replaces File store with Origin. The run report records Origin output, measurements, ELF totals, and self-check values.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to ef4f5

The change adds origin metadata to stored records. The README example is not self-contained and could mislead users copying it, but this is a localized documentation follow-up with no actionable merge-blocking runtime risk.
