help SignalFx FAQ
Who owns SignalFx, and what is its current product name?
SignalFx was acquired by Splunk in 2019 for approximately $1.05 billion and has been rebranded as Splunk Observability Cloud. The core infrastructure monitoring features have been folded into this broader suite.
Does SignalFx rely on proprietary agents to collect server metrics?
Instead of forcing proprietary agents, SignalFx was specifically designed to ingest data using the open-source OpenTelemetry standard and collectd. This allows organizations to monitor cloud-native environments, like Kubernetes clusters, without vendor lock-in.
How does SignalFx handle high-cardinality metrics in AWS environments?
SignalFx uses a custom-built streaming analytics engine that easily handles high-cardinality data, such as tracking EC2 instance IDs or Kubernetes container tags. This allows engineers to filter and group infrastructure metrics in real-time without performance degradation.
Can SignalFx monitor serverless AWS Lambda functions?
Yes, SignalFx provides a specialized AWS Lambda wrapper that automatically captures invocation metrics, errors, and cold starts. This makes it highly effective for monitoring serverless architectures alongside traditional microservices.
