Cadvisor docker swarm

Advisor collects the metric from the host and docker containers. It is deployed as a docker image with shared volumes to docker socket and root file system of the host. Advisor pushed these metrics to a bunch of time-series database including InfluxDB, Prometheus, etc. Add Cadvisor to the monitor-stack.

Swarm will automatically propagate some labels that are used by the dashboard. You can add a separate node-exporter definition in your docker-compose. The cAdvisor is the second metrics collector. And it only becomes interesting from there!

This blog post will explain a few simple and easy to use options. Since its inception at SoundClou Prometheus has been a rising star in the infrastructure monitoring space. Step by step I will build the monitoring tools and then deploy the monit. Its not just about the cluster functionality, its about the deployment as well, when it comes to individual node metrics.

I provides metrics about docker itself. Docker Swarm Cluster Dashboard. I have a Swarm with two nodes and I am running cadvisor as a global service. However my numbers are wrong. When I check the number of containers with the docker command line tools I see that there are containers running on the first node and containers on the second node.

After that it will be possible to visualize the collected performance data using Grafana. We will deploy Gitlab for docker based projects. The instructions are very detailed and work out of the box.

Here are some images after deploying a Couchbase image. DUCP installation consists of an DUCP controller and one or more hosts. The docker stats command and the remote API are useful for getting information on the command line, however, if you would like to access the information in a graphical interface you will need a tool such as CAdvisor.

CAdvisor provides a visual representation of the data shown by the docker stats command earlier. Scheduling services with via docker-compose and scheduling constraints required manual updates when the number of nodes changed in the swarm cluster – definitely not convenient for dynamic scaling of clusters! In this tutorial we will deploy a monitoring stack to docker swarm , that includes Grafana, Prometheus, Node-Exporter, cAdvisor and Alertmanager. So here docker run in a detached mode.

Configuration management and provisioning is done with Ansible. The user can declaratively specify the desired state of various services to run in the Swarm cluster using YAML files. I have setup my monitoring with the cadvisor , node-exporter, prometheus, grafana stack in my clustered environment using docker swarm.

If you remember, we talked about. What is the easiest way to get my actual hostnames picked up by node-exporter, so I can configure my dashboards to filter by node names in grafana? Federation allows a Prometheus server to scrape selected metrics from another Prometheus server. The sole purpose of this Prometheus server is to scrape these services.

It can also scale from a single host to a complex multi-host cluster. This is important because the monitor service is using the monitor network to scrape cadvisor. Type=system deploy labels configures flexible labeling for cadvisor.
