You will see that the Service Down Alert has been fired on the Alert Manager console: # If an alert isn't caught by a route, send it slack.ġ) Shutdown your Quarkus application (or the one being monitored)Ģ) Start Prometheus Server and the AlertManager Edit the alertmanager.yml to include a slack receiver with the correct Slack URL and the Slack channel: route: The last piece of the puzzle is the Alert Manager component which is able to collect and forward messages to a Route. Sending Alerts to Slack from the Alert Manager Here is the Rule file which collects the status of a Quarkus application, which emits metrics about its status: groups:ĭescription: Service is unavailable. How to Create Alerts on the ThinkorSwim Mobile App | TOS Mobile Tutorial # this is the configuration to poll metrics from Quarkus # The job name is added as a label `job=` to any timeseries scraped from this config. # A scrape configuration containing exactly one endpoint to scrape: # Load rules once and periodically evaluate them according to the global 'evaluation_interval'. # scrape_timeout is set to the global default (10s). Default is every 1 minute.Įvaluation_interval: 15s # Evaluate rules every 15 seconds. Scrape_interval: 15s # Set the scrape interval to every 15 seconds. However just to recap, here is the Prometheus configuration file ( prometheus.yml) which loads Rules from the file rule.yml, scraping data from a Quarkus application running on localhost:8080 and sending alerts to the Alert Manager, available with the HTTP schema at localhost:9093 # my global config We have already discussed this step in greater detail in this tutorial: Using Prometheus and Grafana to capture Alerts and visualize Metrics Creating Metrics and Alerts with Prometheus Now we need to start sending our metrics and alerts to Slack. Take note of the Slack URL and keep it safe as it contains a secret! You are done with Slack. You’ll be sent back to your app settings, and you should now see a new entry under the Webhook URLs for Your Workspace section, with a Webhook URL that’ll look something like this: They make use of normal HTTP requests with a JSON payload, which includes the message and a few other optional details.ĥ) Choose the Channel where Incoming Web Hooks will post the messages, in our case the “metrics-project” channel.
