What is rsyslog?
The syslog daemon is quietly becoming an OpenTelemetry-era pipeline, YAML config and all.
rsyslog ships bi-monthly scheduled-stable snapshots of its daily-stable branch, and the last two carried real capability rather than upkeep. April added YAML as an alternative configuration format, an Azure Monitor output, API key authentication for imhttp, and native protobuf encoding for omotel over HTTP. June followed with an Elastic Beats and Lumberjack input, a POSIX FIFO input, experimental TCP stream compression between omfwd and imtcp, and shared per-source ratelimit policy.
What is Greenbone Vulnerability Manager?
Greenbone's scanner daemon is growing a web-application scanning class beside its network roots.
gvmd releases every week or two, and the changelog splits cleanly in three: a sustained build-out of web application scanning, a rewrite of how reports are modeled and exported, and a long tail of memory-management fixes in the C core. Recent versions added web application scanner preferences, scanner verification, and a Web Application VT subtype with a database migration. The report work moved from ad-hoc XML toward a structured report model addressable through new GMP commands.

rsyslog

The syslog daemon is quietly becoming an OpenTelemetry-era pipeline, YAML config and all.
◆ Current state
rsyslog ships bi-monthly scheduled-stable snapshots of its daily-stable branch, and the last two carried real capability rather than upkeep. April added YAML as an alternative configuration format, an Azure Monitor output, API key authentication for imhttp, and native protobuf encoding for omotel over HTTP. June followed with an Elastic Beats and Lumberjack input, a POSIX FIFO input, experimental TCP stream compression between omfwd and imtcp, and shared per-source ratelimit policy.
◆ Where it's heading
Two moves are reshaping what this product is. The configuration story is opening up — RainerScript, rsyslog's bespoke and long-criticized config language, now has a YAML alternative while gaining new helpers of its own. And the transport story is converging on the modern observability stack: native protobuf for OpenTelemetry output, a cloud vendor sink, Beats and Lumberjack ingestion. Underneath both runs continuous defensive hardening across parsers, inputs, outputs, queues and TLS, mentioned in both releases.
◆ Prediction
Expect the YAML configuration path to broaden from alternative to fully supported, and TCP stream compression to move from experimental to stable, since both are flagged as partial in the releases that introduced them.
Greenbone Vulnerability Manager
6.3INFRA · APIS
Greenbone's scanner daemon is growing a web-application scanning class beside its network roots.
◆ Current state
gvmd releases every week or two, and the changelog splits cleanly in three: a sustained build-out of web application scanning, a rewrite of how reports are modeled and exported, and a long tail of memory-management fixes in the C core. Recent versions added web application scanner preferences, scanner verification, and a Web Application VT subtype with a database migration. The report work moved from ad-hoc XML toward a structured report model addressable through new GMP commands.
◆ Where it's heading
Greenbone is widening what gvmd can orchestrate. Network and container scanning were the existing surface; web application scanning is being brought to parity, with its own VT class, preferences, validation, and verification path. In parallel the GMP protocol is gaining first-class report retrieval commands, which makes report data consumable by tooling rather than only renderable. The bug-fix stream is dominated by frees and cleanup in long-lived report paths, the signature of a codebase under memory pressure at scale.
◆ Prediction
Web Application VTs now have a subtype, a migration, and scanner verification, but the audit and scan report commands were added separately; expect the report model work to fold web application results into the same structured retrieval path rather than leaving a parallel one.
