Resumo

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 Enterprise products. Debug logging must be enabled for the Real Protect RC.log to be generated.
Self-Service Supportability Orchestrator (SSSO):
SSSO is a data collection tool that brings all standalone tools that Technical Support uses under a single orchestrator. The tool invokes the right tool at the right time and eases the data collection effort. This tool captures the context in which the data collection happens, which helps report proper telemetry data. For more information, see: KB92519 - Self-Service Supportability Orchestrator data collection tool. Use the SSSO tool in all applicable data collection scenarios rather than opting for manual collection steps, to ensure data consistency.

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)
Application hang or deadlock (not responding and doesn’t recover)
Application crash
Memory leak (user or kernel mode)
Issues related to Device Guard or Credential Guard
One or more ENS components fail to install
The status of ENS is: Endpoint Security Platform isn’t running!
Third-party DLL injection
Issues related to Threat Intelligence Exchange (TIE)
Issues related to ENS Firewall

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

Tools

Self-Service Supportability Orchestrator (SSSO) is a tool that facilitates data collection using multiple standalone tools out of a single interface. SSSO uses predefined playbooks and triggers to automate the collection. For more information, see: KB92519 - Self-Service Supportability Orchestrator data collection tool.
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. PoolMon groups the data 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:

Collect the created dump file, which is in the Procdump folder.
Re-enable ENS Self-Protection.
Collect a MER using the SSSO utility.

Memory leak (user or kernel)

Perform the steps in this section if the symptoms involve a User Mode or Application memory leak. Collect three (3) User Mode or Application crash dumps for analysis.

NOTE: Memory leak data collection needs to be performed over time, just as the memory leak exhibits its behavior over time. For the best data collection results, it’s recommended to reboot the system, and then start the following data collection. This sequence allows the data set to show the existence of the memory leak, over time, as it manifests on the system.

SSSO Playbook (User Mode Leak):

Playbook:		ENS_Process_MemoryLeak.yml
Prerequisites:			ENS Self-Protection must be disabled ENS debug logging Windows Development Kit (WDK) must be installed on the system Windows Debugging Tools must be installed on the system (Included in the WDK installation) PowerShell version 3.0 ENS Exploit Prevention signature "Execution Policy Bypass in PowerShell" rule shouldn't be configured to "Block"
Tools SSSO Executes:				GFlags Taskkill UMDH PoolMon AMTrace Process Monitor WebMER
Notes:	This playbook requires that you provide a target process name for tracking its memory footprint over time. To execute this playbook correctly, ENS Self-Protection must be disabled during testing.

Manual Data Collection (User Mode Leak):

Download ProcDump from the ProcDump downloads page.
Extract ProcDump to the Desktop.
Identify the process name that is leaking memory.
Enable a stack trace on the leaking process. See KB91252 - How to enable a stack trace using the gflags.exe utility.
Wait for the suspect process to show high memory usage.
Open an administrative command prompt, and change directory to C:\Users\username\Desktop\Procdump.
Run the following command: procdump -ma <process name>
Collect the created dump file, which is in the Procdump folder.

@echo on
logman create trace "base_DeviceGuard" -ow -o c:base_DeviceGuard.etl -p "Microsoft-Windows-DeviceGuard" 0xffffffffffffffff 0xff -nb 16 16 -bs 1024 -mode Circular -f bincirc -max 4096 -ets
@echo off
echo
ECHO Reproduce your issue and enter any key to stop tracing
@echo on
pause
logman stop "base_DeviceGuard" -ets
@echo off
echo Tracing has been captured and saved successfully at c:base_DeviceGuard.etl
pause

ENS components fail to install

Perform the data collection steps in this section if one or more components of ENS fail to install.

NOTE: In most situations, it’s ideal that ENS installation data collection be done using the local installation path. This configuration isolates any potential failures to the ENS installer itself, and not task execution or network errors. If data collection must be done from ePO-based deployments, work with Technical Support to make sure this configuration is considered when the data is reviewed.

SSSO Playbook (Local Installation):

Playbook:		ENS_InstallationFailure.yml
Prerequisites:			PowerShell version 3.0 Exploit Prevention signature "Execution Policy Bypass in PowerShell" disabled, or configured to not block ENS debug logging enabled
Tools SSSO Executes:				Process Monitor AMTrace WebMER System File Checker (SFC)
Notes:	This playbook watches for the process spawn of SetupEp.exe, and begins collecting data at the beginning of an ENS local installation.

SSSO Playbook (ePO Deployment):

Playbook:		ENS_InstallationFailure_ePO.yml
Prerequisites:			PowerShell version 3.0 Exploit Prevention signature "Execution Policy Bypass in PowerShell" disabled, or configured to not block ENS debug logging enabled
Tools SSSO Executes:				Process Monitor AMTrace WebMER System File Checker (SFC)
Notes:	This playbook watches for the process spawn of SetupCC.exe, and beings collecting data at the beginning of an ENS ePO-based deployment.

Manual Data Collection:
NOTE: Make sure that you collect the data during a local installation of ENS. Troubleshoot each module as a separate product.

Download and unzip the standalone package from the Product Downloads site.
Start Process Monitor.
Start AMTrace with the rollover option.
Re-create the issue. Run the local installation (setupEP.exe) as administrator and select the single module you’re troubleshooting.
Stop AMTrace and save the log.
Stop Process Monitor and save the log.
Collect a MER file (run as Administrator) using the SSSO utility.
