FAQ# 1- How to add https url to scrap on target prometheus?<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Example 1<\/h2>\n\n\n
Use the following configuration:\r\n\r\n  - job_name: 'domain-job'<\/span>\r\n    scheme<\/span>: https\r\n    static_configs<\/span>:\r\n    - targets: ['myDomain.dev'<\/span>]\r\n<\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\n
Example 2<\/h2>\n\n\n
Add a new<\/span> job that configures both a custom metrics path and scheme.\r\n\r\nIt would look something like this<\/span>:\r\n\r\n- job_name: new<\/span>-job\r\n  scrape_interval<\/span>: 5<\/span>s\r\n  static_configs<\/span>:\r\n    - targets: ['www2.abc.abc.com:443'<\/span>]\r\n\r\n  metrics_path<\/span>: \/servlet\/m<\/span>etrics\/\r\n  scheme: https\r\n\r\nPort 443<\/span> is the HTTPS port, scheme<\/span>: https makes sure the HTTPS protocol is uses and metrics_path points to your custom path with<\/span> the metrics handler.<\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\n
FAQ# 2-  How to setup High available Prometheus multi node clustor for Storage?<\/h2>\n\n\n\n
Prometheus includes a local on-disk time series database, but also optionally integrates with remote storage systems.<\/p>\n\n\n\n
Prometheus’s local storage is limited to a single node’s scalability and durability. Instead of trying to solve clustered storage in Prometheus itself, Prometheus offers a set of interfaces that allow integrating with remote storage systems.<\/p>\n\n\n\n
But, There are some solution available to for Highly available Prometheus multi node clustor<\/p>\n\n\n\n
Federation<\/h2>\n\n\n\n
Federation allows a Prometheus server to scrape selected time series from another Prometheus server. There are different use cases for federation. Commonly, it is used to either achieve scalable Prometheus monitoring setups or to pull related metrics from one service’s Prometheus into another.<\/p>\n\n\n\n

    Thanos<\/h2>\n\n\n\n
    Open source, highly available Prometheus setup with long term storage capabilities.
    Thanos is a monitoring system that aggregates data from multiple Prometheus deployments. This data can then be inspected and analyzed using Grafana, just as with regular Prometheus metrics. Although this setup sounds complex, it\u2019s actually very easy to achieve with the Bitnami Helm charts:<\/p>\n\n\n\n
