设置步骤: Create a read-only Entra application for DumbMonit
  1. In the Microsoft Entra admin center (entra.microsoft.com), open Entra ID → App registrations → New registration, name it DumbMonit, keep a single tenant and register it.

  2. On the Overview page, copy the Application (client) ID and the Directory (tenant) ID.

  3. Open API permissions → Add a permission → Microsoft Graph → Application permissions, add the permissions listed below, then click Grant admin consent.

  4. Open Certificates & secrets → New client secret and copy its Value (not the Secret ID): it is shown once and it expires, so note the date.

  5. In DumbMonit, enter graph.microsoft.com as address, paste the client ID and the secret value, and fill in the Tenant ID option.

注意. Admin consent gives the application tenant-wide read access to the data above. Use a dedicated app registration with only these permissions, and renew its client secret before it expires.

Microsoft Entra ID

entra

Entra ID application secret and certificate expiry, on-premises directory sync age and administrators without MFA, read through Microsoft Graph.

示例

  • Contoso Entra ID

您需要准备

  • Entra application (client credentials)The application (client) ID and a client secret of an Entra app registration with read-only Graph application permissions.

默认端口: 443

内置告警规则 6

Microsoft Azure

azure

Resource Health and active Azure Monitor alerts of an Azure subscription, read through a Reader service principal.

示例

  • Microsoft Azure subscription

您需要准备

  • Entra application (service principal)The client ID and a client secret of an Entra application that has the Reader role on the subscription.

默认端口: 443

内置告警规则 4

  • 警告Azure resource unavailableResource Health reports a resource of the subscription as unavailable for 10 minutes (not counting resources stopped by their owner).
  • 提示Azure resource degradedResource Health reports a resource of the subscription as degraded for 15 minutes.
  • 提示Azure Monitor alert Sev0 or Sev1An Azure Monitor alert of severity Sev0 (critical) or Sev1 (error) is fired and not closed.
  • 警告Monitor unreachableNo measurement received for more than three minutes. bottomk by (target) (1, time() - tlast_over_time(dumbmonit_up[7d]))
设置步骤: Create a read-only application for DumbMonit
  1. In the Azure portal, open Microsoft Entra ID > App registrations > New registration, name it DumbMonit, keep single tenant, then Register.

  2. On the Overview page, copy the Application (client) ID and the Directory (tenant) ID.

  3. Open Certificates & secrets > New client secret, choose a lifetime, then copy the secret Value: it is shown once.

  4. Open Subscriptions > your subscription > Access control (IAM) > Add > Add role assignment, pick the Reader role, select the DumbMonit application, then Review + assign.

  5. Copy the Subscription ID from the subscription Overview page.

  6. In DumbMonit, enter management.azure.com as address, paste the client ID and secret, and fill the Tenant ID and Subscription ID options.

注意. A stopped or deallocated virtual machine is reported by Azure as unavailable on the user's request: it is counted apart and raises no alert. Azure Monitor alerts need the Microsoft.AlertsManagement resource provider registered on the subscription; without it only Resource Health is monitored.

AWS (CloudWatch)

aws

CloudWatch alarms in the ALARM state, EC2 status checks and CPU, and RDS CPU and free storage.

示例

  • Amazon EC2
  • Amazon RDS
  • CloudWatch alarms

您需要准备

  • Access keyAccess key ID and secret access key of a read-only IAM user (or of a user allowed to assume a read-only role).

默认端口: 443

内置告警规则 6

  • 提示AWS CloudWatch alarm in ALARMA CloudWatch alarm has been in the ALARM state for 5 minutes.
  • 提示AWS EC2 status check failedAn EC2 instance has failed an instance or system status check for 10 minutes.
  • 提示AWS EC2 CPU highAn EC2 instance has had a CPU peak above 90 % for 30 minutes.
  • 提示AWS RDS CPU highAn RDS database has had a CPU peak above 90 % for 30 minutes.
  • 提示AWS RDS free storage lowAn RDS database has less than 5 GiB of free storage for 15 minutes.
  • 警告Monitor unreachableNo measurement received for more than three minutes. bottomk by (target) (1, time() - tlast_over_time(dumbmonit_up[7d]))
设置步骤: Create a read-only IAM user for DumbMonit
  1. In the AWS console, open IAM, Policies, Create policy, JSON tab, paste this read-only policy and name it DumbMonitReadOnly.

    {"Version":"2012-10-17","Statement":[{"Effect":"Allow","Action":["cloudwatch:DescribeAlarms","cloudwatch:ListMetrics","cloudwatch:GetMetricData"],"Resource":"*"}]}
  2. Open IAM, Users, Create user: name it dumbmonit, leave console access off, and attach the DumbMonitReadOnly policy.

  3. Open the user, Security credentials, Create access key, choose Application running outside AWS. Copy the access key ID and the secret access key: the secret is shown once.

  4. Optional, to use a role instead: attach the policy to a role that trusts the user, give the user only sts:AssumeRole on that role, and copy the role ARN into the Role ARN option.

  5. In DumbMonit, enter monitoring.<region>.amazonaws.com as the address, paste the key and its secret, and set the same region in the Region option.

注意. Use a dedicated IAM user with only these read permissions, never a key that can change resources. AWS bills GetMetricData per metric requested (USD 0.01 per 1,000): a long check interval keeps the cost low on large accounts.

Cloudflare

cloudflare

Zones, tunnels, certificates, traffic errors and load balancer pools of a Cloudflare account, read through the Cloudflare API.

示例

  • Cloudflare zones and tunnels

您需要准备

  • 警告Monitor unreachableNo measurement received for more than three minutes. bottomk by (target) (1, time() - tlast_over_time(dumbmonit_up[7d]))
设置步骤: Create a read-only API token for DumbMonit
  1. In the Cloudflare dashboard, open My Profile > API Tokens > Create Token > Create Custom Token, and name it DumbMonit.

  2. Add the read-only permissions listed below, and nothing else. The first one is required; the others switch on one part each.

  3. Under Account Resources and Zone Resources, choose the account and the zones to monitor (All zones is fine).

  4. Click Continue to summary > Create Token, then copy the token: it is shown once.

  5. In DumbMonit, use this address and paste the token as API token. Leave Account ID empty unless the token covers several accounts.

    api.cloudflare.com

注意. A part whose permission is missing (or that the plan does not include) is skipped and its readable metric is 0; it does not make the monitor fail. Only the zones the token can see are watched.

Hetzner Cloud

hetzner

Servers, volumes and backups of a Hetzner Cloud project, read through the Hetzner Cloud API.

示例

  • Hetzner Cloud project

您需要准备

  • API tokenA read-only API token of the Hetzner Cloud project.

默认端口: 443

内置告警规则 5

  • 提示Hetzner server not runningA Hetzner Cloud server is not in the running state (off, migrating, stuck starting).
  • 提示Hetzner server CPU sustained highA Hetzner server averages more than 90% CPU over ten minutes, for 30 minutes.

  • 警告Monitor unreachableNo measurement received for more than three minutes. bottomk by (target) (1, time() - tlast_over_time(dumbmonit_up[7d]))
设置步骤: Create a read-only API token for DumbMonit
  1. In the Hetzner Cloud Console, open the project to monitor, then Security > API tokens > Generate API token.

  2. Name it DumbMonit and choose the Read permission (not Read & Write).

  3. Click Generate API token, then copy the token: it is shown once.

  4. In DumbMonit, use this address and paste the token as API token. One monitor reads one project.

    api.hetzner.cloud

注意. A server that is powered off is reported as not running, on purpose or not: mute the rule for it if that is expected. The API allows 3600 requests per hour and project, so server metrics are read for 10 servers by default.

文档

OVHcloud

ovh

State and running tasks of the VPS and dedicated servers of an OVHcloud account, read through the OVHcloud API.

示例

  • OVHcloud VPS and dedicated servers

您需要准备

  • OVHcloud API keysThe application key, and the application secret and consumer key joined by a colon.

默认端口: 443

内置告警规则 4

  • 提示OVHcloud VPS not runningAn OVHcloud VPS is not in the running state for 10 minutes.
  • 警告OVHcloud dedicated server in errorOVHcloud monitoring reports a dedicated server in error, or powered off, for 5 minutes.
  • 信息OVHcloud task in progressOne or more tasks (reboot, reinstall, maintenance) have been pending or running on the servers for an hour.
  • 警告Monitor unreachableNo measurement received for more than three minutes. bottomk by (target) (1, time() - tlast_over_time(dumbmonit_up[7d]))
设置步骤: Create a read-only API token for DumbMonit
  1. Open the OVHcloud token page of your region and sign in with your OVHcloud account. The link pre-selects the two read rights.

    https://eu.api.ovh.com/createToken/?GET=/vps*&GET=/dedicated/server*
  2. Name the script DumbMonit, set Validity to Unlimited, and keep only the two GET rights listed below, then click Create keys.

  3. Copy the Application Key, the Application Secret and the Consumer Key: they are shown once.

  4. In DumbMonit, enter eu.api.ovh.com as address (ca.api.ovh.com for OVHcloud Canada) and paste the Application Key as Application key.

  5. In the second field, type the Application Secret, a colon, then the Consumer Key.

    application_secret:consumer_key

注意. The OVHcloud API publishes no calendar of planned maintenance: DumbMonit sees an intervention only once it has started, as a running task. A VPS you stopped yourself counts as down. A dedicated server is reported in error only if OVHcloud monitoring is enabled on it. Either right may be omitted to watch only the other family.

Infomaniak

infomaniak

Expiry dates, locks and maintenance flags of the products of an Infomaniak account (domains, hosting, mail), read through the Infomaniak API.

示例

  • Infomaniak domains and hosting

您需要准备

  • API tokenAn Infomaniak API token with the Products scope.

默认端口: 443

内置告警规则 5

  • 提示Infomaniak product expiringA product (domain, hosting, mail) expires in less than 14 days.
  • 警告Infomaniak product expiredThe expiry date of a product has passed.
  • 提示Infomaniak product lockedInfomaniak flags a product as locked for an hour.
  • 信息Infomaniak product in maintenanceInfomaniak flags a product as under maintenance for an hour.
  • 警告Monitor unreachableNo measurement received for more than three minutes. bottomk by (target) (1, time() - tlast_over_time(dumbmonit_up[7d]))
设置步骤: Create a read-only API token for DumbMonit
  1. Open the Infomaniak Manager token page and sign in.

    https://manager.infomaniak.com/v3/ng/profile/user/token/list
  2. Click Create a token and name it DumbMonit.

  3. Choose the scopes listed below, and set the validity you want (no expiry avoids renewing it).

  4. Click Create the token, then copy it: it is shown once.

  5. In DumbMonit, enter api.infomaniak.com as address and paste the token. Fill the Account ID option if the token has no Accounts scope.

注意. The Infomaniak API gives no finer state than the expiry date, the lock and the maintenance flags of each product: it does not tell whether a site or a mailbox is up. Use an HTTP monitor for that.
