Management Center Logs

Management Center Logs are diagnostic logs generated by the NCache Management Center process when it records an error. These logs help diagnose Management Center-side errors, such as failures during cache management operations or errors reported while the Management Center communicates with an NCache server node. The NCache Management Center is the web-based interface used to manage and monitor NCache. It is accessed from a browser at http://localhost:8251 or http://<server-ip>:8251.

Use Management Center Logs when an operation fails in the Management Center UI. If the failed operation involves a cache, server node, or NCache Service, review the related Cache Server Logs or Service Logs as well.

When Management Center Logs Help

Management Center Logs are useful when an action fails in the Management Center UI. For example, they can help identify errors that occur while adding or contacting a server node, starting or stopping a cache, loading cache information, or performing management operations from the browser-based interface.

If the Management Center error is related to a cache or service operation, use the Management Center Log to identify the failed action, and then review the related Cache Server Log or Service Log for more detail.

Where Management Center Logs Are Stored

In a default Windows installation, Management Center Logs are stored under:

%NCHOME%\log-files\ManagementCenter

A Management Center log file can use a timestamp-based file name. For example:

log_2026061211.txt

The ManagementCenter folder may be created when the Management Center process records an error. If no Management Center error has been recorded, this folder or log file may not be present. No separate Management Center logging option is required to create these error logs.

Management Center Log Contents

A Management Center log entry can include the timestamp, log level, numeric code, and message. The entry format can appear as follows:

<Timestamp>             <Level>      <Code>    <Message>

Example:

2026-06-12 11:04:46     Error        323       NCache service could not be contacted on node 20.200.20.200. See log file for details.

In this example, the Management Center recorded an error because the NCache Service could not be contacted on the specified node. The timestamp helps correlate the Management Center error with the time of the UI operation. The message identifies the operation failure or the component that could not be reached.

If the message points to a cache, service, or server-node issue, review the related log file for more detail.

Note

If the Management Center does not open in the browser, verify that the NCache Service is running, Management Center auto-start has not been disabled through NCacheServer.StartWebManagement, and port 8251 is reachable. On Windows, startup information may also be available in Windows Event Logging. If required, start the Management Center manually by using the Start-NCacheManagementCenter PowerShell cmdlet.

Reading Management Center Logs

Open Management Center log files in a text editor. Review the timestamp, error level, numeric code, and message to identify the failed Management Center operation. When reviewing the log:

Compare the timestamp with the time of the failed UI operation.
Check whether the message identifies a cache, server node, service, or connection issue.
Review the related Cache Server Log or Service Log if the error involves a cache or NCache Service.
Review Windows Event Logs if the Management Center process or service startup is involved.
