Welcome to the Binoculars project! This is a one-stop solution to your cloud monitoring needs. Binoculars helps you set up Prometheus to pull metrics and visualize them using Grafana
To configure the Binoculars project
Pre-requisites
- Docker Engine (version >=20.10.13)
- Docker Compose (version >=2.3.3)
Note : To install the latest version of docker-compose use the following steps
sudo curl -L https://github.com/docker/compose/releases/download/v2.5.1/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
- Install docker-compose on the docker host.
- Clone this repo on the docker host
- Run the following command from the root of the cloned repo:
docker-compose --env-file ./config/.env.dev up -d
Service | Endpoint |
---|---|
Prometheus | http:https://<host-ip>:9090 |
Grafana | http:https://<host-ip>:3000 |
Pushgateway | http:https://<host-ip>:9091 |
Alert Manager | http:https://<host-ip>:9093 |
Node Exporter | http:https://<host-ip>:9100 |
Blackbox Exporter | http:https://<host-ip>:9115 |
cAdvisor | http:https://<host-ip>:8080 |
The app creates the following named volumes (one for each service) so data is not lost when the app is stopped:
- grafana-storage
- alertmanager-storage
- prometheus-storage
The Grafana console is available at <host-ip>
:3000
To login use the default credentials :-
username : admin
password : admin
After this, you can set your new password.
Navigate to Configuration > Data Sources
The Prometheus container registered at <host-ip>
:9090 will be added as a data source.
To add additional datasources refer the official documentation :
https://grafana.com/docs/grafana/latest/datasources/
You can create a dashboard in Grafana by manually configuring the dashboards while logged into the console. Grafana saves the json configuration of the dashboard to this disk.
Using this project the configuration of dashboards can be stored in the repository and Grafana will use the static configuration files to display the dashboards.
To add new dashboards, add the json configuration of the dashboard to /grafana/dashboard/<folder>
Additionally, Grafana has a wide marketplace of dashboards which can be directly imported using the dashboard ID.
https://grafana.com/grafana/dashboards/
The Prometheus console is available at <host-ip>
:9090
The scraper configuration is part of the project placed at /prometheus/config/prometheus/prometheus.dev.yml
Refer to the documentation to setup your Prometheus server
https://prometheus.io/docs/prometheus/latest/configuration/configuration/
Grafana supports dashboards with Prometheus as the datasource. You can add one or more Prometheus servers as a datasource
Refer documentation : https://grafana.com/docs/grafana/latest/datasources/prometheus/
The Grafana marketplace has multiple dashboards based on the data pushed to Prometheus
Refer documentation : https://grafana.com/grafana/dashboards/?dataSource=prometheus
The Push Gateway enables applications to "push" data to Prometheus as compared to its default pull-based scraping mechanism. The Push Gateway exists as a intermediate cache, to which applications can push the data. The Prometheus will then scrape the metrics from the Push Gateway.
The Push Gateway endpoint is available at <host-ip>
:9091
Refer documentation : https://prometheus.io/docs/practices/pushing/
The Alert Manager application handles alerts sent by the Prometheus server. Combining the metrics ingested by the Prometheus server along with rules, you can raise alerts and route them to integrations like Email, SMS or PagerDuty.
The configuration for the alert manager is part of the project placed at /alertmanager/config/config.dev.yml
Refer documentation : https://prometheus.io/docs/alerting/latest/alertmanager/
There are a number of libraries and servers which help in exporting existing metrics from third-party systems as Prometheus metrics. Some of these exporters are maintained as part of the official Prometheus GitHub organization, those are marked as official, others are externally contributed and maintained.
Extensive list of exporters :
https://prometheus.io/docs/instrumenting/exporters/
The node exporter is used to expose hardware and OS metrics exposed by *NIX Kernels. This can be deployed across your fleet of servers and used to collect useful system metrics.
https://github.com/prometheus/node_exporter
If you have installed the node exporter on your servers, you can configure it to be scraped using the configuration file /prometheus/config/node-exporter-targets/node-exporter-targets.dev.yml
The blackbox exporter allows blackbox probing of endpoints over HTTP, HTTPS, DNS, TCP, ICMP and gRPC.
To monitor a list of endpoints add them to the configuration file /prometheus/config/blackbox-targets/blackbox-targets.dev.yml
https://github.com/prometheus/blackbox_exporter
cAdvisor (Container Advisor) provides container users an understanding of the resource usage and performance characteristics of their running containers. It is a running daemon that collects, aggregates, processes, and exports information about running containers
