What are memory dumps in NCache used for?

In NCache, memory dumps are diagnostic files used for post-mortem debugging and troubleshooting. They are essential for identifying memory leaks, analyzing service crashes, and understanding the state of a distributed cache node at the time of a performance issue.

On which port does Get-MemoryDumpList listen?

By default, the Get-MemoryDumpList cmdlet communicates over port 8250. This is the management port where the NCache Service listens for administrative commands and diagnostic requests.

Can I retrieve memory dump lists from a remote server?

Yes, you can use the -Server parameter to specify the IP address or hostname of any remote node in the NCache cluster to view its stored diagnostic files, provided you have the appropriate network access and security credentials.

Is authentication required for Get-MemoryDumpList?

If NCache security is enabled, you must provide valid credentials. On Windows, use the -Credentials parameter; on Linux, provide the -userid and -password to authorize the diagnostic retrieval process.

Get-MemoryDumpList

The Get-MemoryDumpList cmdlet retrieves and lists all memory dumps stored on the specified NCache server. It is used for troubleshooting issues such as high memory usage, crashes, or performance problems. This cmdlet helps in memory leak analysis, and diagnosing NCache service failures in distributed environments.
