Chaos Studio fault and action library

The following faults are available for use today. Visit the Fault Providers page to understand which resource types are supported.

Time delay

Property Value
Fault Provider N/A
Supported OS Types N/A
Description Adds a time delay before, between, or after other actions. This fault is useful for waiting for the impact of a fault to appear in a service, or for waiting for an activity outside of the experiment to complete. For example, waiting for autohealing to occur before injecting another fault.
Prerequisites N/A
Urn urn:csci:microsoft:chaosStudio:timedDelay/1.0
duration The duration of the delay in ISO 8601 format (Example: PT10M)

    }
  ] 
}

CPU pressure

Property Value
Capability Name CPUPressure-1.0
Target type Microsoft-Agent
Supported OS Types Windows, Linux
Description Adds CPU pressure, up to the specified value, on the VM where this fault is injected during the fault action. The artificial CPU pressure is removed at the end of the duration or if the experiment is canceled. On Windows, the "% Processor Utility" performance counter is used at fault start to determine current CPU percentage, which is subtracted from the pressureLevel defined in the fault so that % Processor Utility will hit approximately the pressureLevel defined in the fault parameters.
Prerequisites Linux: Running the fault on a Linux VM requires the stress-ng utility to be installed. You can install it using the package manager for your Linux distro,
APT Command to install stress-ng: sudo apt-get update && sudo apt-get -y install unzip && sudo apt-get -y install stress-ng
YUM Command to install stress-ng: sudo dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm && sudo yum -y install stress-ng
Windows: None.
Urn urn:csci:microsoft:agent:cpuPressure/1.0
Parameters (key, value)
pressureLevel An integer between 1 and 99 that indicates how much CPU pressure (%) will be applied to the VM.
virtualMachineScaleSetInstances An array of instance IDs when applying this fault to a Virtual Machine Scale Set. Required for Virtual Machine Scale Sets.

      ], 
      "duration": "PT10M", 
      "selectorid": "myResources" 
    } 
  ] 
} 

Limitations

  • The fault can only be applied to an existing Network Security Group.
  • When an NSG rule that is intended to deny traffic is applied existing connections won't be broken until they've been idle for 4 minutes. One workaround is to add another branch in the same step that uses a fault that would cause existing connections to break when the NSG fault is applied. For example, killing the process, temporarily stopping the service, or restarting the VM would cause connections to reset.
  • Rules are applied at the start of the action. Any external changes to the rule during the duration of the action will cause the experiment to fail.
  • Creating or modifying Application Security Group rules isn't supported.
  • Priority values must be unique on each NSG targeted. Attempting to create a new rule that has the same priority value as another will cause the experiment to fail.

Azure Cache for Redis reboot

Property Value
Capability Name Reboot-1.0
Target type Microsoft-AzureClusteredCacheForRedis

Prerequisites The target Azure Cache for Redis resource must be a Redis Cluster, which requires that the cache must be a Premium Tier cache. Standard and Basic Tiers aren't supported.
Urn urn:csci:microsoft:azureClusteredCacheForRedis:reboot/1.0
Fault type Discrete

shardId The ID of the shard to be rebooted.

Sample JSON

{
  "name": "branchOne",
  "actions": [
    {
      "type": "discrete",
      "name": "urn:csci:microsoft:azureClusteredCacheForRedis:reboot/1.0",
      "parameters": [
        {
          "key": "RebootType",
          "value": "AllNodes"
        },

          "value": "0"
        }
      ],
      "selectorid": "myResources"
    }
  ]
}

Limitations

  • The reboot fault causes a forced reboot to better simulate an outage event, which means there is the potential for data loss to occur.
  • The reboot fault is a discrete fault type. Unlike continuous faults, it's a one-time action and therefore has no duration.

Fault Type Discrete
Parameters (key, value)
certificateName Name of AKV certificate on which fault will be executed

Key Vault Update Certificate Policy

Property Value
Capability Name UpdateCertificatePolicy-1.0
Target Type Microsoft-KeyVault
Description Certificate policies (examples: certificate validity period, certificate type, key size, or key type) are updated based on the user input and reverted after the fault duration.
Prerequisites For OneCert certificates, the domain must be registered with OneCert before attempting to run the fault.
Urn urn:csci:microsoft:keyvault:updateCertificatePolicy/1.0
Fault Type Continuous
Parameters (key, value)
certificateName Name of AKV certificate on which fault will be executed
version The certificate version that should be updated; if not specified, the latest version will be updated.
enabled Bool. Value indicating whether the new certificate version will be enabled
validityInMonths The validity period of the certificate in months
certificateTransparency Indicates whether the certificate should be published to the certificate transparency list when created
certificateType the certificate type
contentType The content type of the certificate, eg Pkcs12 when the certificate contains raw PFX bytes, or Pem when it contains ASCII PEM-encoded btes. Pkcs12 is the default value assumed
keySize The size of the RSA key: 2048, 3072, or 4096
exportable Boolean. Value indicating if the certificate key is exportable from the vault or secure certificate store
reuseKey Boolean. Value indicating if the certificate key should be reused when rotating the certificate
keyType The type of backing key to be generated when issuing new certificates: RSA or EC
