The Prometheus project is designed to be deployed into a standard Nubis Account. It takes advantage of the standard deployment found here. For further specifics about Prometheus consult the documentation here.
NOTE: The line colors are representative and are for readability only. They are not intended to indicate any underlying protocol or specific communication details.
The Nubis Prometheus deployment consists of:
- A single EC2 instance acting as a Prometheus server
- An Auto Scaling group to provide resiliency
- A S3 log bucket where backups are stored
Prometheus scrapes different kind of exporters, as it discovers them. Each of them needs a distinct TCP port for it, and here is our current list:
| Exporter | Port | Discovery |
|---|---|---|
| Node | 9100 | sd:node-exporter |
| Fluentd | 9101 | sd: fluentd |
| Consul Statd | 9102 | sd: consul |
| Apache | 9103 | sd:apache sd:apache-exporter |
| MySQL | 9104 | sd:mysqld-exporter |
| ElasticSearch | 9105 | sd:es |
| Squid | 9106 | sd:proxy |
| Consul | 9107 | sd: consul |
| Fluentd Apache | 9108 | sd:apache sd:apache-exporter |
| Cloudwatch | 9116 | Internal |
| Cloudwatch Billing | 9117 | Internal |
Details for the deployment including; naming conventions, relationships, permissions, etcetera, can be found in the Terraform template used for deployment. Links to specific resources can be found in the following table.
