Identify code vs. infra issues, their source, impact, and ownership
Kerno correlates issues with key change events and telemetry data across Cloud, Infrastructure, Applications, Git, and CI/CD so your team can quickly figure out whether an issue is code or infrastructure related, where it started, and its impact across your services so you can notify and align the relevant people.
Give developers code level insights for faster troubleshooting
Kerno gives developers and on-call engineers the context they need down to the broken line of code, and Git blame insights to quickly spot the root cause without manually sifting through uncorrelated logs and dashboards.
Reduce Ongoing Observability Cost
Minimize data ingress and storage cost
Kerno collects data only when issues occur, reducing data storage and transfer costs by up to 90% while giving developers and on-call engineers the necessary insights without compromising cost, granularity, or scale.
No ongoing manual maintenance
Automated Continuous instrumentation, Zero downtime upgrades, No Custom dashboards - free up DevOps and SRE Teams to focus on business value instead of toil work to maintain application observability.
Stay in control of your sensitive data
Kerno is deployed in-cluster, which means logs, and traces (that contain PII) never leave your infrastructure. For developers, Kerno obfuscates sensitive data so they can work in real-time without compromising on security.
Fair and predictable pricing without surprises
Say goodbye to complex pricing models and unexpected costs and never worry again about unpredictable volume-based pricing.
