LogDNA announced the general availability of LogDNA Agent 3.3, which introduces Linux and ARM64 support to Rust Agent.

The new support in Rust Agent provides improved performance and enables a few features previously only available for Kubernetes customers, such as various configurations within the Agent and the ability to run as a non-root user.

Additionally, LogDNA have added in Prometheus Metrics that help provide insights into the Agent.

Finally, given the newest Linux support, support matrix has been updated to reflect the changes.

A few tests were ran with Node and Rust Agents and it was found that the memory usage of the Rust Agent was significantly more efficient than that of the Node Agent.

Given the lower, more predictable memory usage, introducing Linux support with Rust Agent takes advantage of these performance gains.

With the new Linux support, customers can now utilize features previously only available for user ingesting Kubernetes logs.

Specifically, Linux customers can now do the following:

- Run their Agent as Non-Root for enhanced security.

- Configure regex redaction rules to allow for peace of mind that Personally Identifiable Information (PII) is not exposed.

- Configure stateful lookback to guarantee that logs are never dropped, even while the Agent is being restarted or upgraded.

Metrics related to the Agent are exposed, such as the number of log files currently tracked or the number of bytes parsed, along with process status information. Through integrating with Prometheus, customers can have a better understanding of how the Agents are behaving and even alert on when metrics are abnormal.
