Choose a monitoring check

A practical reference to every built-in endpoint, from ping to quantum and BLE.

Pick the question you want answered

An endpoint is the type of recurring check your agent performs. Use reachability checks for “Can I reach it?”, content checks for “What did it return?”, and security checks for a specific security property. The status explains the outcome; elapsed time alone does not.

The endpoint menu follows your selected agent and account. Ask the assistant to show available endpoints for a location if you are unsure. Custom Connects appear where you have deployed them.

Website and network checks

EndpointUse it forHow to interpret it
icmpDevice reachability using pingMeasures reply duration. Firewalls can block ICMP even when other services work.
httpWebsite request completionMeasures a request and body download. A completed 4xx/5xx response can still count as reachable; inspect its status.
httpsCertificate-check request modeChecks certificate trust/expiry when the request uses TLS. A certificate within seven days of expiry is treated as a failed check. See the address note below.
httphtmlWebsite HTML without JavaScriptFetches HTML; it does not test a rendered web application.
httpfullFull page loading including JavaScriptUses a browser. Requires a capable Linux/Windows agent; unavailable under the Android browser policy and on ESP32.
dnsDomain resolutionShows lookup status and duration; the chosen location’s resolver matters.
rawconnectTCP service reachabilityConnects to a host/port. Use the service’s actual port; successful TCP does not prove application health.
smtpMail-server connection and HELOChecks the SMTP greeting exchange, not whether a message reaches an inbox.

The .NET and ESP32 address-handling paths currently differ for HTTP/HTTPS, including the .NET certificate endpoint’s URL normalisation. Do not use an https monitor alone as proof of certificate validation for every input. For a focused certificate investigation, use the OpenSSL diagnostic workflow and inspect its result.

Changes and local configuration

EndpointUse it forRequirements
sitehashDetect changes to rendered page contentBrowser-capable agent. The page is compared with a saved baseline; a reset can establish a new baseline. Dynamic pages may change legitimately.
configintegrityRead a local Debian configuration-integrity resultA local administrator must install/configure the checker and publish its status file. The monitor reads that result; it does not itself inspect all system files.

Security and quantum checks

EndpointUse it forRequirements
nmapScheduled port/service scanFull Nmap on capable .NET agents; a bounded TCP/service-hint implementation on ESP32.
nmapvulnScheduled Nmap vulnerability-script scanNmap scripts and a capable agent. Not supported on ESP32.
quantumTest post-quantum TLS key exchangeSupported cryptographic algorithms on the selected agent.
quantumcertInspect certificate post-quantum propertiesSeparate from key exchange and ordinary certificate trust.

Run these only on authorised targets. For an immediate investigation, use on-demand diagnostics rather than adding a recurring monitor. Read quantum result interpretation before treating a check as an assessment of your whole infrastructure.

Bluetooth checks

EndpointUse it forRecorded information
blebroadcastOne device and a selected metricDevice address plus format/metric in Args. The selected reading is displayed in its own unit.
blebroadcastlistenDiscover nearby advertisementsA bounded capture window and diagnostic list. Its duration is not a sensor reading from a chosen device.

See sensor setup and the metric reference. Live capture needs Windows, Android or ESP32 hardware in radio range; Linux does not currently provide live BLE scanning.

Crawl and Space maintenance

EndpointUse it forRequirements
crawlsiteCrawl internal site links and generate trafficBrowser-capable Linux/Windows agent; bounded depth/page count.
dailycrawlLower-frequency daily crawlingBrowser and daily scheduling.
dailyhugkeepaliveDaily activity for a Hugging Face SpaceBrowser workflow; depends on the Space and upstream page behaviour.
hugwakePeriodic attempt to wake/restart a sleeping SpaceBrowser workflow and appropriate access.

These maintenance checks are not a guarantee that an external provider will keep a Space running. View Hugging Face Spaces guidance for provider behaviour.

Timing and scheduling

Timeout is the execution budget in milliseconds. Longer scan/crawl/discovery jobs have endpoint-specific extended budgets; their displayed duration is converted automatically. Skip cycles adjusts host cadence, while some endpoints have daily or other scheduling rules. It is not an exact wall-clock scheduler.

Only genuine timing measurements with a defined rating use latency categories. A quantum scan’s completion time, a configuration outcome and a voltage reading have different meanings. Use alerts for operational limits, charts for trends and platform comparison to choose the right agent.
