Splunk today said it acquired Omnition, a startup that is developing a observability platform for microservices-based applications. The vendor didn’t disclose terms of the deal, but it comes just weeks after Splunk announced an agreement to pay $1.05 billion for SignalFx.

CEO Spiros Xanthos founded Omnition last year, and it has yet to formally launch. Before that he started and ran Pattern Insights, which VMware acquired in 2012 and used for its analytics platform. Xanthos remained at VMware until February 2015 before moving on to found another startup, ezhome, before Omnition.

In a blog post about the acquisition, Xanthos wrote “we founded Omnition to build the most powerful Observability platform, making distributed tracing the core of it. We realized the prior generation monitoring and troubleshooting tools that some of us helped build are inadequate for the complexities of microservice-based, cloud-native applications.”

However, the startup hasn’t started shipping this platform. So its technology is, as of yet, unproven.

Splunk got its start in the security information and event management (SIEM) space, alongside vendors including IBM and McAfee — and several newer startups that want to displace the old guard and pull a bigger piece of the lucrative $124 billion market.

Like several of its competitors, Splunk has been steadily adding technologies to its SIEM platform including observability and application performance monitoring (APM). Buying Omnition brings more than a dozen engineers with expertise in tracing and observability to Splunk. Plus, adding its technology to Splunk’s portfolio will boost its APM capabilities and “help customers gain insights across the entire enterprise application portfolio from on-premises data centers to cloud-based applications and infrastructure,” said Tim Tully, chief technology officer at Splunk in a blog post.

The startup also has strong roots in the open source community. Its team, alongside Google and Microsoft, maintains OpenCensus, an open source set of libraries for various languages that allow users to collect application metrics and distributed traces, then transfer the data to a backend of choice in real time. Additionally, Omnition is a founding member and one of the top three contributors to OpenTelemetry, a project that merges OpenCensus and OpenTracing to standardize the instrumentation and telemetry data collection under the Cloud Native Computing Foundation (CNCF).
