Add-TestData

The Add-TestData PowerShell cmdlet allows users to add random test data to the cache for performance testing, verification, and simulation. By adding configurable key-value pairs with absolute expiration (default 300 seconds), this cmdlet is ideal for cache startups, load testing, and benchmarking. Users can customize the number of items, data size, and expiration time to meet specific testing needs. It supports single or multiple servers and secure authentication, ensuring flexible integration and reliable performance checks.

Add-TestData -CacheName [-Server] `
             [-ItemCount] [-DataSize] `
             [-AbsoluteExpiration] [-LoadBalancerEnabled] `
             [-TlsCertPath] [-TlsCertPassword] `
             [-NoLogo] [-Credentials]

Examples

This command adds 10 items (it is set to 10 by default) to the defaultCache with an expiry of 5 minutes.

Add-TestData -CacheName defaultCache

This command adds 100 items to the defaultCache with an expiry of 5 minutes.

Add-TestData -CacheName defaultCache -ItemCount 100

This command adds 100 items of size 2KB to the defaultCache with an expiry of 5 minutes.

Add-TestData -CacheName defaultCache -ItemCount 100 `
             -DataSize 2048

This command adds 100 items to the defaultCache with an expiry of 5 minutes.

Add-TestData -CacheName defaultCache -ItemCount 100 `
             -Server "20.200.20.11,20.200.20.12"

This command adds 100 items to the defaultCache with expiry of 5 minutes through the specified load-balanced server, 20.200.20.11.

Add-TestData -CacheName demoCache -ItemCount 100 -LoadBalancerEnabled -Server 20.200.20.11

This command adds 100 items to the demoCache with expiry of 5 minutes using the specified DNS, David-Watson.

Add-TestData -CacheName demoCache -ItemCount 100 -Server David-Watson

This command adds 100 test items to defaultCache using the specified servers with mutual TLS (mTLS) enabled. It runs from a machine where NCache is not installed and uses C:\certs\client.pem to authenticate the machine running the cmdlet. The -TlsCertPassword parameter decrypts the certificate’s password-protected private key. Omit this parameter if the private key is not encrypted.

Add-TestData -CacheName defaultCache -ItemCount 100 `
             -Server "20.200.20.11,20.200.20.12" -TlsCertPath "C:\certs\client.pem" `
             -TlsCertPassword "clientKeyPassword"

This command adds 10 items (it is set to 10 by default) to the defaultCache with an expiry of 5 minutes, using security credentials.

Add-TestData -CacheName defaultCache -Credentials(Get-Credential john_smith)

Note

The parameters with asterisk (*) on their names are the required parameters and the rest are optional.

Parameters	Data Types	Description	Default Value
`-CacheName*`	`<String>`	Specifies the name of the cache to which test data will be added. NOTE: The cache must already exist on the source server.	-
`-Server`	`<String>`	Specifies a server name where the NCache Service is running and a cache with the specified cache-name is registered. NOTE: Comma-separated IP addresses are to be specified in case of multiple servers inside double quotes.	IP of local machine
`-ItemCount`	`<Long>`	Specifies the number of test items to be added to the cache.	10
`-DataSize`	`<Long>`	Specifies the size of each item to be added to the cache.	1024 bytes
`-AbsoluteExpiration`	`<Double>`	Specifies the time in seconds for the Absolute expiration of the test data items. Its minimum value is 15 seconds.	300 seconds
`-LoadBalancerEnabled`	`<SwitchParameter>`	Specifies whether to use a load balancer when connecting to the cache.	False
`-NoLogo`	`<SwitchParameter>`	Suppresses display of the logo banner.	False
`-TlsCertPath`	`<string>`	Path to the client PEM certificate used to authenticate the machine running the NCache PowerShell cmdlet when connecting to an NCache server with mutual TLS (mTLS) enabled. The PEM file must contain the private key, leaf certificate, and any intermediate certificates. You can generate a certificate using `New-NCacheTlsCertificate`. This parameter is required when running the PowerShell module from a machine where NCache is not installed and the server requires mTLS. On a machine with an NCache server installation, the node's own certificate is used automatically. Relative paths are resolved against the current PowerShell location, and the file must exist. To configure the certificate presented by the server, use `-CustomCertificatePath`.	False
`-TlsCertPassword`	`<string>`	Password used to load the encrypted private key in the PEM file specified by `-TlsCertPath`. Required only when the private key is password-protected. Not needed for an unencrypted private key. The password is used only to load the client certificate for the current command's connections. It is not saved in the NCache server configuration.	False
`-Credentials`	`<pscredential>`	Specifies the user credentials required to authorize access for the specified operation. These credentials should belong to a user with the appropriate permissions at the node.	-
