Rookout announces Live Logger which will complement their existing Live Debugger for dynamic observability into modern applications.

With the click of a button, Live Logger enables developers to switch logs on and off on-demand, as well as change their verbosity on the fly, significantly reducing logging noise and cost, while simultaneously increasing their efficacy.

“All developers have the same fear of not having the right logs when they need them most -- so unfortunately the trend has become to log everything,” said Shahar Fogel, CEO of Rookout. “Logs quickly become expensive to store and noisy at scale. Live Logger lets developers increase log verbosity when they are being helpful, but just as importantly, allows them to be shut off when they are creating noise.”

In traditional software development workflows, engineers are forced to make upfront decisions about where exactly to add log lines and at what level of verbosity. Once the logs are deployed, any future changes require the developer to write more code, stop the application, and then redeploy it again. Engineers either ignore the logs and fly blind without the context needed to make informed decisions, or they fly slow because they spend countless hours digging through logs to find the required data.

Rookout Live Logger makes these concerns obsolete by enabling developers to switch logs on and off without having to write more code and restart the application. This dynamic instrumentation is made possible via bytecode manipulation, typically seen in cybersecurity but uncommon amongst developer tooling. Combined with Rookout’s core Live Debugging product, these tools give developers instant access to the code-level data they need to troubleshoot and understand complex, modern applications.
