Message delivery guarantees in security data pipelines

How delivery guarantees, flow control, and buffers behave in security data pipelines across UDP, TCP, HTTP, gRPC, OpenTelemetry Collector, Kafka, and AxoSyslog.

If you're transporting log data, switching from syslog or HTTP to gRPC can dramatically improve efficiency, reliability, and scalability. Read our blog to learn why.

Why Use OpenTelemetry gRPC for Log Data Transport

Why switch log transport to OpenTelemetry gRPC? Compare efficiency, reliability, and scale against syslog and HTTP — and when gRPC is the right call.

Scaling syslog over UDP to 1M events per second with eBPF — Axoflow blog cover

Scaling syslog to 1M EPS with eBPF

How to parallelize syslog message processing to scale syslog over UDP reception on a single node: dos, dont's, and trade-offs, and the power of eBPF.

Kernel and syslog-ng tuning to avoid losing messages with syslog over UDP — diagram cover

Tune the Kernel & syslog-ng to Stop UDP Syslog Loss

syslog over UDP drops messages under load. The exact kernel and syslog-ng buffer tuning to minimize loss — settings you can apply today.

Where and how likely syslog over UDP loses messages

Why Syslog over UDP Loses 30–40% of Messages (and How to Fix It)

Syslog over UDP can drop 30–40% of messages. Why packets are lost and the kernel + syslog-ng tuning that stops it — without ripping out UDP.
