Where are NCache Management Center logs located?

Management Center logs are stored under '%NCHOME%\log-files\ManagementCenter' on Windows and '/opt/ncache/log-files/ManagementCenter' on Linux.

Why is the ManagementCenter log folder not visible?

The ManagementCenter directory is created automatically only when the Management Center process encounters and records an error.

What port does the NCache Management Center use by default?

The NCache Management Center runs on port 9801 by default.

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:9801 or http://<server-ip>:9801.

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, NCache Management Center Logs are stored under:

%NCHOME%\log-files\NCacheManagementCenter

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

log_2026061211.txt

The NCacheManagementCenter 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, application domain, logger name, thread name, log level, and message. The entry format can appear as follows:

<Timestamp>    <AppDomain>    <LoggerName>    <ThreadName>    <Level>    <Message>

Example:

2026-10-08 11:35:54,297    Alachisoft.NCache.ManagementCenter    NCacheManagementCenter    8    ERROR    Alachisoft.NCache.WebManager.Pages.UserLoginModelFailed to authenticate 'john_smith'. System.DirectoryServices.Protocols.LdapException: The supplied credential is invalid.

The fields provide the following information:

Timestamp: Indicates when the event was recorded.
AppDomain: Identifies the application domain in which the event occurred.
LoggerName: Identifies the component or logger that generated the entry.
ThreadName: Identifies the thread associated with the logged operation.
Level: Indicates the severity of the event, such as ERROR.
Message: Describes the event or failure and can include exception details and stack traces.

Management Center log messages can span multiple lines when an exception or stack trace is recorded. Use the timestamp, component information, and exception details to correlate the error with the Management Center operation being performed.

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 9801 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.
