What can I do with Buoyant Cloud?

Here are some of the tasks you can perform using Buoyant Cloud, if the Buoyant Cloud agent is installed and running on the cluster. Note: Only Linkerd health monitoring is available for organizations on the free plan.

Linkerd control plane health

1. Get notified if a control plane component is down, has high resource usage or latency, or has a low success rate.
2. View Linkerd CPU usage and memory usage by the control plane or data plane, and in total.
3. View Linkerd control plane success rate, latency, and request volume.

Linkerd data plane health

1. View CPU and memory usage of each individual Linkerd proxy.
2. Find Linkerd proxies running older versions.
3. Find Linkerd proxies consuming a lot of resources.

Metrics

1. View real-time request volume, success rate, and latency for any meshed, HTTP-based Kubernetes Deployment, StatefulSet, or DaemonSet.
2. View real-time TCP read bytes, write bytes, and connections for any meshed Kubernetes workload.
3. View real-time CPU and memory usage for any Kubernetes workload (meshed or not).
4. View historical graphs of the above metrics.

Rollouts and other cluster changes

1. Track all code rollouts. 
2. Annotate the code rollout events to include release notes, links to the code, and more.
3. During a rollout, watch pods get created and transition to running.
4. Investigate a failed code rollout.
5. Correlate changes in metrics to changes on your cluster.
6. Know when there’s a new cluster or workload on one of your clusters.

Understanding dependencies

1. Understand dependencies between workloads.
2. Know when a workload has a new client or a new dependency.

Kubernetes

1. View number of running pods for all workloads - and whether it matches the expected number of pods.
2. View the list of pods for a workload, with pod status and number of restarts.
3. View Kubernetes events pertaining to each rollout.
