HTTP Probe
Introduction
The HTTP probe allows to monitor a specific URI over the http or https protocol
Features
- Roundtrip time, the roundtriptime for the http(s) request is measured and returned.
- HTTP status code monitoring
Deployment
The HTTP probe can easily be deployed using our appliance manager.
Probe configuration
| Property | Description |
|---|---|
| URI | URI of the website you want to monitor |
| Timeout | Timeout in seconds should be a value between 0 and 240. The default timeout is 10.0 |
| Verify SSL | If turned off, the check ignores invalid certificates; when on, the URI must have a valid certificate. Nots, this is only applicable for HTTPS URI. The default is off. |
| With payload | Retrieves the payload, bare in mind the payload is limited to 500 Kb |
| Allow redirects | When turned on, redirects are followed. |
Tip
When monitoring cloud services, enable Allow redirects as these services heavily rely on http redirects.
