Monitors
Uptime and health checks for HTTP, TCP, UDP, and ping targets.
Introduction
A monitor repeatedly checks whether a target is up, on a schedule you define, and keeps a history of the results. Unlike serverlet or proxy metrics, a monitor doesn’t have to check something running on Futrou at all — the target can be any HTTP endpoint, host, or port reachable from the monitor’s region, on or off the platform.
Creating a monitor
- Region — where the check runs from, or Auto to let Futrou choose.
- Name — used in the dashboard to identify the monitor.
- Type —
HTTP / HTTPS,Ping,TCP, orUDP. See Check types below. - Target — what to check, in a format matching the type (a URL for HTTP, a host for Ping, a
tcp://host:portorudp://host:portURI for TCP/UDP). - Request method — HTTP monitors only; the HTTP method to send,
GETby default. - Interval — a 6-field, seconds-leading cron expression, e.g.
*/30 * * * * *for every 30 seconds. - Timeout — how long, in seconds, to wait for a response before counting the check as failed. Defaults to 10 seconds.
- Enabled — whether the monitor is actively scheduled. See Enabling and disabling.
Check types
- HTTP / HTTPS — requests the target URL with the configured method and reports success based on the response. Best for web services and APIs, including a dedicated health-check endpoint.
- Ping — an ICMP ping to a host. Confirms basic network reachability without checking any particular service on it.
- TCP — opens a TCP connection to
host:portand confirms it succeeds. Good for checking that a database, cache, or other non-HTTP service is accepting connections. - UDP — the UDP equivalent, for services that communicate over UDP.
Interval
The interval is a standard 6-field cron expression with seconds as the leading field, rather than the usual 5-field minute-leading form — this is what allows checks more frequent than once a minute (*/30 * * * * * for every 30 seconds, 0 * * * * * for once a minute, and so on).
Enabling and disabling
A monitor can be toggled without deleting it — Enabled on the monitor itself, or the enable/disable actions from its page. A disabled monitor keeps its configuration and check history but isn’t scheduled, so it doesn’t run and doesn’t count toward alerting until you turn it back on.
Triggering a check
Use Trigger to run a check immediately, outside its normal schedule — useful right after creating a monitor, or to confirm a fix took effect without waiting for the next scheduled interval.
Checks
The Checks tab on a monitor’s page shows its recent check history: each entry’s status (up/down), latency, timestamp, and any message returned (an error, or the reason a check failed). This is the quickest way to see whether a monitor has been flapping or how its latency trends over time.
Logs
The Logs tab streams the monitor’s own log output, separate from its check history — searchable by free-text, and filterable by a time range (startAt/endAt). A tail view shows the most recent entries (up to 100 by default) without paging through history.
Deleting
Deleting a monitor removes it and its schedule from Nasua along with its Futrou Cloud record; check history isn’t retained afterward.
Region
A monitor runs its checks from a specific region, or you can leave it on Auto. The region determines where the check originates from — relevant if you’re checking latency or reachability from a particular geography, or checking a target (like a private region’s service) that’s only reachable from nearby.
Pricing
Monitors don’t currently carry a separate price — see Billing for how workspace credit is charged for billed services.
