Overview

Infrastructure monitoring lets you track the health of any external service your Salesforce org depends on — REST APIs, databases, payment gateways, internal services, or anything else reachable over the network. When a service goes down, Zentien records the outage and surfaces it on the Correlation page alongside any Salesforce error spikes that occurred at the same time.

​
Check types

​
HTTP

Makes an HTTP GET request to a URL and expects a 2xx response. Any non-2xx response or a timeout counts as a failure. Use for: REST APIs, health endpoints, web services.

​
TCP

Opens a TCP connection to a host and port. If the connection is refused or times out, the check fails. Use for: databases (PostgreSQL, MySQL, Redis, MSSQL), SFTP servers, custom TCP services.

​
Heartbeat

A passive check — your system pings Zentien instead of Zentien polling yours. If no heartbeat arrives within the configured interval, the check is marked DOWN. Use for: scheduled jobs, nightly batch processes, cron tasks. Add a POST to the heartbeat URL at the end of your job.

​
Creating a check

  1. Go to Infrastructure → New Check
  2. Select the check type
  3. Enter a name and target (URL or host:port)
  4. Set the polling interval (how often to check)
  5. Set the timeout (how long to wait before marking it DOWN)
  6. Optionally select a Notification Channel to be alerted when the check goes DOWN or recovers
  7. Save
The check starts polling immediately.

​
Heartbeat URL

When you create a heartbeat check, you receive a unique URL: 
POST https://api.zentien.io/api/infrastructure/{checkId}/heartbeat
Call this URL at the end of your scheduled job or batch process. No authentication required — the checkId is the secret. Example (cURL): 
curl -X POST https://api.zentien.io/api/infrastructure/{checkId}/heartbeat
Example (Apex): 
HttpRequest req = new HttpRequest();
req.setEndpoint('https://api.zentien.io/api/infrastructure/{checkId}/heartbeat');
req.setMethod('POST');
new Http().send(req);
If the heartbeat URL is not called within the configured interval, the check flips to DOWN.

​
Reading the dashboard

The Infrastructure page shows all your checks with:
  • Status badge — UP (green), DOWN (red), or UNKNOWN (grey, before first result)
  • Uptime bar — last 60 check results as coloured segments, oldest to newest left to right
  • Response time — last recorded response time in milliseconds (HTTP and TCP)
  • Last checked — time of the most recent check
Click any check to open the detail panel showing the full result history and response time trend.

​
Alerts

Select a Notification Channel on a check to receive a notification when it goes DOWN and when it recovers. The same Slack, email, and webhook destinations used for error alerts are supported.
