High level approach

We assume the alerts and logs are tagged with the repository name. We then query alerts in Datadog by the tag with the repo name, and filter the active alerts.

Prerequisites

For the code below to work, please follow the guide on Connecting to Datadog.

Code

github.datadog.logs-alerts.integration.example.js

module.exports = {
    metadata: {
        name: 'github-datadog-logs-alerts',
        description: 'Show any active alerts from Datadog in Github, and jump from Github to Logs and Alerts for this repository',
        match: {
            contextType: 'github',
            context: {
                'page.repository': { startsWith: 'my-org/' }
            }
        },
        requiredSecrets: ['DATADOG_API_KEY', 'DATADOG_APP_KEY'],
        cache: 300
    },
    run: async function (context, secrets = {}) {

        // adjust this to your Datadog instance
        const DATADOG_HOST = 'https://api.datadoghq.com';
        
        // assume the alerts for services belonging to this repository are tagged using the repository tag
        const repoTag = `repository:${context.page.repository}`;

        // if using Datadog EU instance, please change the url accordingly
        const url = `${DATADOG_HOST}/api/v1/monitor?group_states=alert&monitor_tags=${encodeURIComponent(repoTag)}`;
        const response = await fetch(url, {
            method: 'GET',
            headers: {
                'DD-API-KEY': secrets.DATADOG_API_KEY,
                'DD-APPLICATION-KEY': secrets.DATADOG_APP_KEY,
                'Content-Type': 'application/json'
            }
        });

        if (!response.ok) {
            throw new Error(`Datadog API error: ${response.status} ${response.statusText}`);
        }

        monitorList = await response.json();
        // Filter monitorList to only include monitors with overall_state === "Alert"
        monitorList = Array.isArray(monitorList)
            ? monitorList.filter(monitor => monitor.overall_state === "Alert")
            : [];
        const activeAlertsCount = monitorList.length || 0;
  
        // Build Datadog logs and alerts URLs for this repository
        const logsUrl = `${DATADOG_HOST}/logs?query=${encodeURIComponent(repoTag)}`;
        const alertsUrl = `${DATADOG_HOST}/monitors/manage?q=tag%3A"${encodeURIComponent(repoTag)}`;

        const results = [
            {
                type: 'link',
                content: `${activeAlertsCount} alert${activeAlertsCount === 1 ? '' : 's'}`,
                href: alertsUrl,
                status: activeAlertsCount > 0 ? 'important' : 'success',
                icon: 'datadog'
            },
            { type: 'link', content: 'Logs', href: logsUrl, icon: 'datadog' }
        ];

        return results;
    }
};
