prometheus, grafana, alertmanager: number of alerts

 prometheus alerts counts

from : https://jaanhio.me/blog/visualizing-alerts-metrics-grafana/ + https://community.grafana.com/t/how-to-get-the-time-range-selected-on-the-dashboard-into-a-variable/2868/3

(sum by (alertname) (changes(ALERTS_FOR_STATE[$__range]) AND ignoring(alertstate) max_over_time(ALERTS{alertstate="firing"}[$__range])) + (count by (alertname) (changes(ALERTS_FOR_STATE[$__range]) AND ignoring(alertstate) max_over_time(ALERTS{alertstate="firing"}[$__range])) * 1))

Then use a grafana panel as "Gauge" with the following options :

* Value options: show calculate, Last *

* Orientation = horizontal, and 

Number of alerts by alert name of the last 2 months

PromQL = sum by(alertname) (changes(ALERTS_FOR_STATE[65d]))

Number of alerts by instance over the last 2 months

PromQL = sum by(instance_name) (changes(ALERTS_FOR_STATE[65d]))

Request Bin / http endpoint for testing

from : https://grafana.com/tutorials/grafana-fundamentals/#create-a-contact-point-for-grafana-managed-alerts

 

 In this step, we’ll set up a new contact point. This contact point will use the webhooks channel. In order to make this work, we also need an endpoint for our webhook channel to receive the alert. We will use requestbin.com to quickly set up that test endpoint. This way we can make sure that our alert is actually sending a notification somewhere.

1. Browse to requestbin.com.
2. Under the Create Request Bin button, click the public bin link.

Your request bin is now waiting for the first request.

1. Copy the endpoint URL.

=> tool to test what is received !

• Community: In the book The Burnout Fix, Dr. Jacinta Jimenez details the importance of a “psychologically safe” environment — that is, one that “empowers employees to share their selves and their ideas without fear of negative consequences.” If you feel supported, connected, and unafraid to show up authentically at work, you are far less likely to experience burnout.

parse json in terraform

 https://www.reddit.com/r/Terraform/comments/c07dgc/using_external_jsons_as_data_source/

    data "http" "example" {
  url = "..."
}

locals {
  example_response = jsondecode(data.http.example.body)
}

From there you can manipulate that data structure as you need. If you want to produce a map of lists then probably your next step would be to use two nested for expressions. I’m just guessing what you want the values in those lists to look like, but here’s a starting point:

    locals {
  example_rules = {
    for k, m in local.example_response : k => [
      for k, v in m : {
        key   = k
        value = v
      }
    ]
  }
}
