The Observability Pipeline that delivers monitoring as code on any cloud

Consolidate monitoring tools & fill gaps in observability. Eliminate data silos & automate diagnosis & self-healing — from bare metal to Kubernetes.

$ sensuctl create -r -f monitoring/
check "node-exporter" created
check "tls-cert" created
asset "sensu-plugins/sensu-plugins-ssl:1.0.0" created
filter "oncall" created
handler "slack" created
handler "ansible-tower" created

Why choose Sensu? Because the rules have changed.

The shift from static to dynamic infrastructure requires a change in approach to monitoring, from host-based to functional role-based. Connectivity moves from remote polling to publish-subscribe, the control plane moves from point-and-click interfaces to infrastructure as code workflows and self-service developer APIs.

Observability Pipeline

With Sensu Go, you can fill gaps in observability between metrics, logging, & tracing. Consolidate existing monitoring tools, including Nagios, StatsD, Telegraf, Prometheus, & more.

Monitoring as code

Sensu Go codifies monitoring workflows into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.

Multi-cloud

Embrace auto-scaling with confidence & real-time visibility. Sensu automates the registration and de-registration of servers, containers, services, apps, functions, and connected devices.

STEP 1: Install Sensu Go
STEP 2: Install the Sensu Go CLI
STEP 3: Configure your first monitor

Install Sensu Go

Deploy our official Docker container to get up and running in seconds. Follow these steps, then visit your Sensu Go dashboard at http://localhost:3000/.

(You can click on the copy icon on bottom right to copy and paste into a terminal shell window).

$ sudo docker network create sensu
$ sudo docker volume create sensu-backend-data
$ sudo docker run -d --rm --name sensu-backend \
  --network sensu -p 8080:8080 -p 3000:3000 \
  -v sensu-backend-data:/var/lib/sensu \
  sensu/sensu:6.14.0 sensu-backend start
$ sudo docker run -d --rm --network sensu -p :3030 \
  sensu/sensu:6.14.0 sensu-agent start \
  --backend-url ws://sensu-backend:8081 --deregister \
  --keepalive-interval=5 --keepalive-warning-timeout=10 --subscriptions linux
$ curl -s http://localhost:8080/version
{"etcd":{"etcdserver":"3.3.13","etcdcluster":"3.3.0"},"sensu_backend":"6.14.0"}

Install the Sensu Go CLI

Sensuctl is a command line interface for running commands against Sensu clusters. Install sensuctl on your laptop to gain access to your multi-cloud monitoring control plane.

$ curl -LO https://s3-us-west-2.amazonaws.com/sensu.io/sensu-go/6.14.0/sensu-go_6.14.0_linux_amd64.tar.gz
$ sudo tar -xzf sensu-go_6.14.0_linux_amd64.tar.gz -C /usr/local/bin/
$ sensuctl configure -n --url http://127.0.0.1:8080 \
  --username admin \
  --password "P@ssw0rd!" \
  --namespace default
$ sensuctl cluster health
ID                NAME     ERROR   HEALTHY
8927110dc66458af  default          true
$ sensuctl cluster id
sensu cluster id: "227b26eb-26c4-46b2-bc7c-8c080b072e6b"

Configure your first monitor

Sensu makes it easy to deploy instrumentation (e.g. plugins or scripts) and configure new monitors. This example shows how to monitor NTP system clock drift.

$ sensuctl asset add sensu/monitoring-plugins:2.2.0-1
fetching bonsai asset: sensu/monitoring-plugins:2.2.0-1
added asset: sensu/monitoring-plugins:2.2.0-1
$ sensuctl check create ntp \
  --runtime-assets "sensu/monitoring-plugins" \
  --command "check_ntp_time -H time.nist.gov --warn 0.5 --critical 1.0" \
  --output-metric-format nagios_perfdata \
  --publish="true" --interval 30 --timeout 10 --subscriptions linux
$ sensuctl event list
ENTITY        CHECK      OUTPUT                                                                    STATUS  SILENCED   TIMESTAMP

Supercharge your Ops & SRE teams at a fraction of the cost of other solutions.

Traditional monitoring tools are cost-prohibitive to operate at even moderate scale, and legacy monitoring tools are incompatible with the ephemeral nature of public cloud and cloud-native platforms. Upgrade to Sensu today to embrace your multi-cloud operation with confidence – and without breaking the budget! Keep your existing custom plugins or use new ones, integrate best of breed products and transition seamlessly!
