![]() On the right hand side, change the "Panel title" to CPU Utilization and under “Axis” -> “Left Y” change “Unit” -> “Misc” -> percent (0-100). Select CloudWatch as the source, the “Region” your EC2 instance is in, set “Namespace” to AWS/EC2, “Metric Name” to CPUUtilization, “Stats” to Average, “Dimensions” to InsanceId =. In your Grafana instance, go to “Create” (plus sign) -> “Dashboard” If you don’t have CloudWatch setup as a data source, check out the Grafana docs to add CloudWatch. This tutorial uses CloudWatch Metrics, but you can use any metrics tool and data source you want, such as Prometheus or InfluxDB. Now you need a way to visualize the Chaos Experiments. In the “Request URL” field add your Grafana endpoint. Click “New Webhook”.Įnter the Name and Description of your webhook. In Gremlin, go to “Settings” (people icon next to the “Halt All Attacks” button) -> “Team Settings” -> “Webhooks”. Once logged in, you need to add a webhook to send attack data over to Grafana. If you don’t have an account, you can request a free trial. Next, log into Gremlin where you can add the Grafana webhook to our account. Keep your API key handy, you'll need to reference this API key in Step 3. ![]() Then, click “Add API Key” -> add a “Key name” such as Gremlin Key and set the “Role” to Editor and click “Add”. In your Grafana UI, head over to “Configuration” (gear icon) -> “API Keys.” You first need to generate an API key that will allow you to securely send data to Grafana. Gremlin account and at least one agent installed.CloudWatch added as a data source in Grafana.Grafana installed or a Grafana cloud account. ![]() If you're curious to see demo of running chaos experiments using Gremlin and Grafana, watch our on-demand webinar. Writing directly to Grafana’s database can impact performance if you are running hundreds of attacks per day across many applications, but for most use cases, this won’t have an impact. The list of options for a data source to hold Gremlin events is long, but this tutorial provides an example of writing directly to the Grafana API in Graphite format. Combined, these two tools can be an effective combination to ensure the dashboards and alerts provided are actionable and useful to reduce mean time to detection (MTTD). Grafana is an open source, highly flexible analytics and visualization platform that can ingest data from many data sources and provide powerful dashboards, reports, and alerts. Gremlin is a safe, simple, and secure way to run Chaos Engineering on your systems to improve their reliability and tune your monitoring.
