Procedura minima di raccolta dei dati per problemi di Endpoint Security

This article provides basic information about the Minimum Data Collection steps for troubleshooting common ENS issues.

Make sure that all logs are collected from the same system that experiences the issue, and that all logs are collected at the same time. The logging data time stamps can be used to troubleshoot the problem.

Mismatched logs from different systems, or logs collected at different times, can't be used for troubleshooting. Such logs might result in having to recollect all Minimum Data Collection logs.

IMPORTANT: The following files are needed for Technical Support:

Minimum Escalation Requirements (MER) files with debug logging for ENS are needed for all issues. For information about debug logging, see Verify whether ENS debug logging is enabled. For information about MER files, see: KB59385 - How to use MER tools with supported McAfee products. Debug logging must be enabled for the Real Protect RC.log to be generated.

Collect other files and logs for each issue below:

Slow boot or startup
Slow logon
Slow application startup (reproducible or random)
Slow application performance (reproducible or random)
Slow system performance (reproducible or random)
System hang or deadlock
System bug check (blue screen)

Depending on the issue, you might need the following tools:

Tools

AMTrace is an internal tool to collect logging data from AMCore (last updated October 11, 2018). To use AMTrace to collect logging data from AMCore:
1. Prepare AMTrace:
  1. Download the zip package ENSDataCollect.zip from the Attachment section of this article.
  2. Extract the contents to the Desktop.
2. Run AMTrace:
  1. Click Start, type cmd.exe in the Search bar, right-click cmd.exe from the list, and click Run as administrator.
  2. When you’re ready to start a trace, use the command option below, that the relevant data collection section requires.
    
    NOTE: The following are the paths to the AMTrace.exe file locations:
    - C:\Users\username\Desktop\ENSDataCollect\AMTracex86
    - C:\Users\username\Desktop\ENSDataCollect\AMTracex64
    AMTrace command options:
    - To use the AMTrace onboot option, run the following command:
      
      AMTrace.exe -b onboot -m 4GB
      
      This command instructs the tool to begin a trace at the next boot.
      NOTES:
      
      The "GB" is case sensitive. This example limits the log size to 4 GB. 10 MB is the minimum accepted value, and 2 GB is the default, if not specified.
      
      This option doesn’t support the alternative logging modes described below.
    - To use AMTrace with the now option, run the following command:
      
      AMTrace.exe -b now -m 4GB
      
      IMPORTANT: The AMTrace now uses the rollover option by default.
      
      This command instructs the tool to begin a trace immediately, and to limit the log size to 4 GB per .etl file. When the log reaches 4 GB, a new log is created. Each log is appended with _1, _2, and so on, until you stop the trace, the user logs off, or you shut down the system.
      
      NOTE: The "GB" is case sensitive.
    - To use AMTrace without the rollover option:
      Choose an appropriate logging method for the issue you want to record:
      
      AMTrace.exe -b now -m 4GB -L stop
      AMTrace.exe -b now -m 4GB -L circular
      
      The stop mode creates a trace session that stops logging once reaching the size limit.
      The circular mode creates a trace session that logs to a single file. After reaching the maximum size, older events are overwritten.
      
      NOTE: The "L" and "GB" are case sensitive.
  3. Stop the trace and save the log. Use the following command:
    
    AMTrace -e
  4. When possible, AMTrace tries to automatically rename the resulting ETL files to include the start time and stop time of the logging in the file name. For example, amtrace_20200704.010203-010305.etl would indicate that logging began 2020-07-04 (July 4, 2020) at 1:02:03, and continued until 1:03:05.
    If AMTrace is unable to rename the file when logging stops, it’s still possible to rename the file manually with another AMTrace command:
    
    AMTrace.exe --datestamp *.etl
    
    This command accepts wildcards (* or ?) to reference multiple characters or a single character respectively. This command renames the specified file or files to include the start and stop times in the file name. It doesn’t affect files that already have the datestamp added.
To confirm whether an AMTrace is in progress, run the following command to list any active traces:

AMTrace -q

For a demonstration of how to collect AMTrace data with this procedure, watch the following video:
GFlags allows you to enable and disable advanced internal system diagnostic and troubleshooting features. You can run GFlags from a command prompt window or use its graphical user interface dialog box. It’s most often used to turn on indicators that other tools track, count, and log.
MER collects event logs, file version details, files, process details, and registry details from McAfee products installed on your computer. Technical Support uses data collected to resolve problems. For more information, see: KB59385 - How to use MER tools with supported McAfee products.
Process Monitor is a tool from Microsoft that monitors and displays all file system activity on a Windows operating system in real time. Use the tool in system administration, computer forensics, and application debugging. How to use Process Monitor:
1. Prepare Process Monitor:
  1. Download Process Monitor from the Process Monitor downloads page.
  2. Extract Procmon.exe to the Desktop.
2. Run Process Monitor:
  1. When you’re ready to start Process Monitor, use the option below, that the relevant data collection section requires.
    - To immediately start Process Monitor:
      1. Run Procmon.exe and it automatically starts to capture process information.
      2. To stop Process Monitor, press Ctrl+E or click File and deselect Capture Events. Press Ctrl+E again to resume data collection.
      3. To save the log, click File, Save... (select All Events and use the native PML format).
    - To enable the Process Monitor boot logging option if needed by the relevant data collection section:
      1. Open the Process Monitor console.
      2. Click Options.
      3. Click Enable Boot Logging.
      4. Click OK on the pop-up window. The next time a reboot occurs, a boot trace log is created.
      5. To save the log, run Process Monitor again and click File, Save... (select All Events and use the native PML format).
For a demonstration of how to collect Process Monitor data with this procedure, watch the following video:
Procdump is a command-line utility used to monitor an application for CPU spikes. It generates crash dumps during a spike that an administrator or developer can use to determine the cause of the spike.
Perfmon is a tool that administrators can use to examine how programs, running on their computers, affect the computer's performance. Use the tool in real time to analyze how running programs affect system performance. You can also use this tool to collect log file information for system performance data analysis later.
PoolMon displays data that the operating system collects about memory allocations from the system paged and nonpaged kernel pools, and memory pools used for Terminal Services sessions. The data is grouped by pool allocation tag. Microsoft Technical Support uses that information to find kernel mode memory leaks.
VMware converter is a free utility from VMware that helps convert Windows and Linux-based physical systems to VMware virtual machines. You can also use it to convert third-party image formats such as backup images and other virtual machines to VMware virtual machines. Use this tool to create virtual machines to provide to Technical Support for troubleshooting.
WinDbg is a Microsoft distributed debugger for the Windows operating system. Use this tool to debug user mode applications, device drivers, and the operating system itself in kernel mode. It has a graphical user interface and is more powerful than Visual Studio Debugger.

Windows Performance Recorder (WPR) is a performance recording tool from Microsoft that is based on Event Tracing for Windows (ETW). It records system events that you can then analyze by using Windows Performance Analyzer (WPA). How to use WPR:

Click Start, type cmd.exe in the Search bar, right-click cmd.exe from the list, and click Run as administrator.
Type wprui.exe and press Enter to start WPR.

NOTE: If the program doesn’t run or isn’t found, you must first install it. WPR is part of the Windows Performance Toolkit. It’s available from the Windows SDK or the Windows Assessment and Deployment Kit:
- For Windows SDK, see the Windows SDK downloads page.
- For Windows Assessment and Deployment Kit, see the Windows Assessment and Deployment Kit downloads page.

Choose to use a Performance Scenario and other settings, as recommended in the following table:

Performance Issue	Performance Scenario	Detail Level	Logging Mode	Profiles to Include	Number of Iterations
Slow boot or logon	Boot	See below	File	First-level Triage, CPU usage, File I/O activity, Minifilter I/O Activity	At least 1
High CPU usage	General	See below	File	First-level Triage, CPU usage, File I/O activity, Minifilter I/O Activity	N/A
Application is slow or unresponsive	General	See below	File	First-level Triage, CPU usage, File I/O activity, Minifilter I/O Activity	N/A

WPR data is collected to allow for deeper analysis of the problem. The "Minifilter I/O Activity" option is one of the most important and is located under the "Scenario Analysis" section.

The use of WPR places extra strain on the system, which can change or mask the original problem you want to investigate. Collect two data sets with different detail levels. Use the Light setting to show the issue, and the Verbose setting to allow a data set suitable for deeper analysis. Capture at least 30 seconds.

When possible, collect a WPR log without the issue while you perform the same task, for comparative purposes. A data set without ENS present is needed to establish the benchmark for expected performance.

For a demonstration of how to collect WPR data with this procedure, watch the following video:

The following sections describe what data to collect for each type of issue:
