A year and a half after last raising capital, infrastructure monitoring startup Logz.io Inc. today announced that it has closed another $52 million funding round led by General Catalyst.

Boston-based General Catalyst’s previous bets include high-profile tech unicorns such as Airbnb Inc. The venture capital firm was joined by a half-dozen other investors in Logz.io’s latest round, including OpenView Venture Partners, which led its previous capital raise.

Logz.io provides a cloud-based platform that helps information technology teams monitor the health of their applications and the underlying hardware. Administrators can use it to catch problems such as service failures that may disrupt business operations. The platform organizes the data collected from malfunctioning systems, visualizes it and filters unnecessary information to ease the troubleshooting process.

The offering is built on three popular open-source technologies that are widely used for infrastructure monitoring: Elasticsearch, Logstash and Kibana. Logz.io has expanded upon the tools’ features with proprietary capabilities designed to automate certain troubleshooting tasks.

One such enhancement is a technology dubbed Unified Machine Intelligence. It’s an artificial intelligence that analyzes issues Logz.io’s customers encounter in their environments to understand common problem patterns. When the software finds a malfunction like, say, a payment processing failure that it has seen before, it will provide suggestions on where administrators should look to find the root cause.

The platform also lends itself to cybersecurity monitoring. Earlier this month, Logz.io launched a module that enables network protection teams to keep an eye out for malicious activity such as unauthorized network access attempts.

The startup will use the new $52 million in funding to continue developing new features and to establish more industry partnerships. As part of the effort, Logz.io expects to grow its current headcount of 175 workers to 250 by the end of the year.

Logz.io has raised more than $98 million to date. The startup competes with bigger rivals such as Splunk Corp. and Sumo Logic Inc., which a few weeks ago closed a $110 million investment of its own at a valuation exceeding $1 billion.
