Information on where the different Symantec Data Loss Prevention (DLP) Server log files are located and what information they contain.


DLP provides many operational log files that can be used to interpret how the system is running.

In DLP 15.0 and earlier, the log folders are found in the following locations:

  • Linux: /var/log/SymantecDLP/
  • Windows: \SymantecDLP\Protect\logs\

In currently supported DLP versions (that list here) the log folders are found in the following locations:


  • C:\ProgramData\Symantec\DataLossPrevention\EnforceServer\<version-number>\logs\
  • C:\ProgramData\Symantec\DataLossPrevention\DetectionServer\<version-number>\logs\


  • /var/log/Symantec/DataLossPrevention/EnforceServer/<version-number>/
  • /var/log/Symantec/DataLossPrevention/DetectionServer/<version-number>/


Log File Name




This file describes communications between the detection server and the agents. Look at this log to troubleshoot the following problems:

* Connection to the agents

* To find out why incidents do not appear when they should

* If unexpected agent events occur

Endpoint Detection Servers


This file is typically very small, and it shows how the application processes are running. The BoxMonitor process oversees the detection server processes that pertain to that particular server type. For example, the processes that run on Network Monitor are file reader and packet capture.

All Detection Servers


This log file may be helpful for troubleshooting ContextExtractor issues.

All Detection Servers


Contains the log statements that the Network Discover native code emits. Currently contains the information that is related to ,pst scanning. This log file applies only to the Network Discover Servers that run on Windows platforms.

Discover Detection Servers


This log file pertains to the file reader process and contains application-specific logging, which may be helpful in resolving issues in detection and incident creation. Look at this log file to find out why an incident was not detected. One symptom that shows up is content extractor timeouts

All Detection Servers


This log file pertains to the Incident Persister process. This process reads incidents from the incidents folder on the Enforce Server, and writes them to the database. Look at this log if the incident queue on the Enforce Server (manager) grows too large. This situation can be observed also by checking the incidents folder on the Enforce Server to see if incidents have backed up.

Enforce Server


This log file contains information when an EDM profile is indexed. It also includes the information that is collected when the external indexer is used. If indexing fails then this log should be consulted.

Enforce Server, also on a computer running a Remote Indexer


This log file is a trace of JDBC calls to the database. By default, writing to this log is turned off.

Enforce Server


This log file is a detailed log of the connections between the  Enforce Server and the detection servers. It gives details around the information that is exchanged between these servers including whether policies have been pushed to the detection servers or not.

Enforce Server


This log file pertains to the packet capture process that reassembles packets into messages and writes to the drop_pcap directory. Look at this log if there is a problem with dropped packets or traffic is lower than expected. PacketCapture is not a Java process, so it does not follow the same logging rules as the other Symantec Data Loss Prevention system processes.

Network Monitor Detection Server only


This log file describes issues with PacketCapture communications.

Network Monitor Detection Server only


This log file pertains to SMTP Prevent only. The log file is primarily for use in cases where SmtpPrevent_operational0.log is not sufficient.

SMTP Prevent Detection Server


Where target is the name of the scan target. All white spaces in the target's name are replaced with hyphens. This log file pertains to Discover server scanning. It is a file by file record of what happened in the scan. If the scan of the file is successful, it reads success, and then the path, size, time, owner, and ACL information of the file scanned. If it failed, a warning appears followed by the file name.

Discover Detection Server


This operational log file pertains to SMTP Prevent only. It is the primary log for tracking health and activity of a Mail Prevent system. Look at this file for information on the communications between the MTA and detection server.

SMTP Prevent Detection Server


This log file contains information for any action that involves  the user interface. The log includes the User Interface red error message box, password fails when logging on, and Oracle errors (e.g., ORA–#).

Enforce Server

Tomcat\ Localhost_access_log.<date>.txt

This log contains the record of all URLs requested.

Enforce Server


This log file contains minimal information –stdout and stderr  only (fatal events).

Enforce Server


This log file contains minimal information –stdout and stderr  only (fatal events).

Enforce Server


This log file contains minimal information –stdout and stderr  only (fatal events).

All Detection Servers


This log file contains minimal information –stdout and stderr only (fatal events).

Enforce Server


This log file pertains to the Notifier service and its communications with the Enforce Server and the DetectionServerController service. Look at this file to see if the DetectionServerController service registered a policy change.

Enforce Server


This access log file pertains to Web Prevent only. It records all the requests that Web Prevent processes. It is similar to Web access logs for a proxy server.

Web Prevent Detection Servers


This operational log file pertains to Web Prevent only. It reports the operating condition of Web Prevent such as whether the system is up or down, connection management, and so on. This log is the primary log file for tracking Web Prevent operations.
