FAQ

What are the open-source tools that NudgeBee uses?​

Agent​

  • Prometheus (or VictoriaMetrics) - Metrics Collection and alerting
  • OpenCost for calculating cost metrics for Pods/Workloads etc.
  • Trivy for generating Docker image vulnerability related security recommendations
  • Popeye for generating best practices related recommendations
  • Kubewatch for K8s events collection

What are the ML libraries that NudgeBee uses? What are the dependencies?​

  • TensorFlow for recommendations for replicas
  • AWS Bedrock using LLAMA (optional) for AI-based recommendations on logs/errors

What are the pre-conditions(software/hardware) for installing NudgeBee on my cluster?​

For Agent:​

  • Helm chart for installation
  • Prometheus, if already configured, else NudgeBee agent installs it
  • Currently, NudgeBee uses Loki for log queries. For log-specific features, we will require Loki running on the cluster. We don't provide Loki as part of the Agent Installer.
  • Permissions as specified in Helm charts

What is the typical system requirement for running NB on my cluster? What is the expected cost of operations for running the base NudgeBee​

For Agent:​

Agent has multiple components. All of them combined take around 6GB memory and 3 core CPUs This also includes Prometheus(Alertmanager/KubestateMetrics) If we remove Prometheus components, then it takes around 3GB and 2 cores

For Server:​

All server components take around 12GB RAM and 4 core CPUs This includes running postgres/rabbitmq etc. If the customer is managing these dependencies, then it will take around 8GB RAM and 2 core CPUs

How NudgeBee Optimizations Work with GitOps​

Raise PRs from NudgeBee

  • We have added support for raising PRs from specific optimization screens in NudgeBee.

GitOps(Flux/Argo) Reconciliation

  • Disable reconciliation for given resources.

NudgeBee Autopilot Reconciliation

  • NudgeBee provides annotations which can be used to ignore specific resources.

GitOps Way Of Configuring NudgeBee Optimizations -

  • We want to provide this as an option using CRDs, though it's part of the roadmap.

Can NudgeBee work on K3s/Kind/Minikube?​

Yes, please refer to the Installation Guide for local testing.

Does NudgeBee Docker images have any security vulnerabilities?​

No, NudgeBee uses Alpine-based images to reduce overall size and security issues. We use AWS ECR and NudgeBee for scanning images maintained by us. We can share a security report for that as per request.

Does NudgeBee have VAPT reports?​

Yes, we use ZAP/manual pen testing for our security testing and can share reports based on request.

Can I configure multiple clusters within a single NudgeBee server?​

Yes, configure agents on each targeted cluster.

What are different NudgeBee distributions?​

NudgeBee has both SaaS and self-hosted solutions. As an end-user, you can use the SaaS solution to quickly validate/test the product and the self-hosted solution for long-term deployment (if there are compliance constraints which don't allow any kind of data movement).

What is the NudgeBee release cycle?​

We target to have a weekly release cycle with hotfixes as per requirements. We follow SemVer for our versioning.

Can you provide more details on Data Retention Policies?​

Currently, NudgeBee stores most of the data in Agents which get deployed on the cluster, so data remains within the cluster. Data retention for Agent components (traces/metrics/logs) is configurable and can be managed by the customer.

Agents store the following data:​

Traces - Using ClickHouse, you can adjust how long you want to retain ClickHouse data. The default is 7 days. Metrics - Using Prometheus, you can adjust Prometheus data retention. Logs - We integrate with existing log services like Loki/ELK, so again, it depends on their data retention.

Servers store the following data:​

Aggregated Metrics - We do aggregation on a daily basis. No retention policy yet. Would like to understand the use case. Events - Troubleshooting pages. Current retention is 60 days. You can make it configurable. Deleted Pods/Workloads etc. - We store deleted workloads/pods etc. No retention policy yet. Will share once that is there, maybe by next week.

Does NudgeBee support Anomaly Detection?​

No, this is part of the roadmap.

Does NudgeBee support Predictive Analysis?​

Yes, NudgeBee uses predictive analytics for replica rightsizing and continuous rightsizing.
