Dial testing — endpoint availability
The Dial Test screen is not part of this release. Its user interface exists in the product’s source, and the server keeps the rules for it, but the agent cannot run the checks, so the screen is not mounted and nothing in the navigation leads to it. An earlier version of this page described it as available; it was not.
What to use instead
Section titled “What to use instead”Scheduled checks of an endpoint are available through three apps in the App Market (Configure → Manage Apps → App Market):
| app | what it checks |
|---|---|
| HTTP Heartbeat | an HTTP endpoint on a schedule, recording availability and response time |
| TCP Heartbeat | a TCP connection on a schedule, recording availability and connect time |
| ICMP Heartbeat | a host by ping on a schedule, recording availability and round-trip time |
They run on your agents, like any other collection: the check happens from the machine the agent is on, which is the vantage point you usually want for “is this service reachable from where it is used”. An ICMP check confirms the host answers, not that any service on it does — pair it with an HTTP or TCP check for that.
The results are metrics, so they chart in Metric Explorer and alert like any other series (Alerts and notifications).
