Syslog message formats
Common Event Format (CEF) and Log Event Extended Format (LEEF) log message formats are slightly different. For example, the "Source User" column in the GUI corresponds to a field named "suser" in CEF; in LEEF, the same field is named "usrName" instead. Log message fields also vary by whether the event originated on the Deep Security Agent or Manager and which feature created the log message.
If your syslog messages are being truncated, it may be because you're using User Datagram Protocol (UDP). To prevent truncation, transfer your syslog messages over Transport Layer Security (TLS) instead. For instructions on switching to TLS, see Define a Syslog configuration.
Basic syslog format is not supported by the Anti-Malware, Web Reputation, Integrity Monitoring, and Application Control protection modules.
If the syslog messages are sent from the manager, there are several differences. In order to preserve the original Deep Security Agent hostname (the source of the event), a new extension ("dvc" or "dvchost") is present. "dvc" is used if the hostname is an IPv4 address; "dvchost" is used for hostnames and IPv6 addresses. Additionally, the extension "TrendMicroDsTags" is used if the events are tagged. (This applies only to auto-tagging with run on future, since events are forwarded via syslog only as they are collected by the manager.) The product for logs relayed through the manager will still read " Deep Security Agent"; however, the product version is the version of the manager.
CEF syslog message format
All CEF events include 'dvc=IPv4 Address' or 'dvchost=Hostname' (or the IPv6 address) for the purposes of determining the original Deep Security Agent source of the event. This extension is important for events sent from a Deep Security Virtual Appliance or Manager, since in this case the syslog sender of the message is not the originator of the event.
Base CEF format: CEF:Version|Device Vendor|Device Product|Device Version|Signature ID|Name|Severity|Extension
To determine whether the log entry comes from the Deep Security Manager or a Deep Security Agent, look at the "Device Product" field:
Sample CEF Log Entry: Jan 18 11:07:53 dsmhost CEF:0|Trend Micro|Deep Security Manager|<DSM version>|600|Administrator Signed In|4|suser=Master...
To further determine what kind of rule triggered the event, look at the "Signature ID" and "Name" fields:
Sample Log Entry: Mar 19 15:19:15 root CEF:0|Trend Micro|Deep Security Agent|<DSA version>|123|Out Of Allowed Policy|5|cn1=1...
The "Signature ID" value indicates what kind of event has been triggered:
Signature IDs | Description |

20 | Log-only Firewall rule |
21 | Deny Firewall rule |
30 | Custom Integrity Monitoring rule |

1,000,000-1,999,999 | Trend Micro IPS rule. The signature ID is the same as the IPS rule ID. |
2,000,000-2,999,999 | Integrity Monitoring rule. The signature ID is the Integrity Monitoring rule ID + 1,000,000. |
3,000,000-3,999,999 | Log Inspection rule. The signature ID is the Log Inspection rule ID + 2,000,000. |
4,000,000-4,999,999 | Anti-Malware events. Currently, only these signature IDs are used:
