Alerts

Alert rules

Alerts evaluate server and managed-resource metrics every minute and create a record when a rule remains true for the configured number of consecutive checks. Open Monitoring > Alerts and switch between Rules and Records.

Rule Fields

FieldMeaning
NameHuman-readable purpose of the rule.
MetricThe value or resource state to evaluate.
TargetResource selected by metrics that apply to a specific disk, network interface, website, service, project, container, app, database, or certificate.
Operator and thresholdComparison and value that must be true. Units depend on the metric.
Consecutive checksFrom 1 to 60 one-minute evaluations. It prevents a single sample from triggering a noisy alert.
Silence periodFrom 0 to 1440 minutes. Matching events are still recorded, but repeated notifications are suppressed.
Notification channelsZero or more enabled SMTP channels. A rule with no channel records alerts without sending a message.
EnabledWhether the rule is evaluated.

Supported Metrics

AcePanel provides 21 alert categories:

CategoryMetrics and typical unit
ComputeCPU usage (%), memory usage (%), Swap usage (%), load 1/5/15 (load value).
DiskDisk space (%), inode usage (%), disk read and write throughput (bytes/s). Select a disk when required.
NetworkInbound and outbound throughput (bytes/s). Select an interface when required.
WebsiteHTTP 5xx count/rate, website error state, and website days remaining.
Managed resourcesService, project, container, application, and database state. Select the concrete target.
CertificateCertificate days remaining.

The form shows the target selector and unit appropriate to the selected metric. Do not copy a numeric threshold from a percentage rule into a throughput, load, or remaining-days rule without reviewing the unit.

Common Workflow

  1. Configure and test an SMTP channel in Monitoring Settings.
  2. Create one rule with a descriptive name and the narrowest correct target.
  3. Set a threshold and consecutive-check count that represent a real incident.
  4. Choose a silence period that avoids duplicate messages without hiding a long outage.
  5. Save the rule and confirm it appears as enabled.
  6. Review Records after a controlled threshold test.

Records and Notification Semantics

Alert records are the audit trail of rule evaluations that triggered. A silence period suppresses additional notifications for the same rule; it does not discard records. Selecting no channel is useful when you want a record but no outbound message.

If an alert never arrives, check the rule status, target, unit, consecutive-check count, silence period, channel enablement, and SMTP test result. For application failures, also open the corresponding service or task log.
