Data analytics startup Wavefront announced today its launch from stealth after an $11.5 million funding round led by Sequoia.

Wavefront also said Sequoia Ventures’ Bill Coughran will join its board.

The startup says it “allows users to visualize and query a wide range of metrics, including computing load and performance data” in real time to prevent outages.

To date, the Palo Alto-based company has raised at least $20.5 million, with investments from Sutter Hill Ventures and the Webb Investment Network.
