    System Log Fields

    Format: FUTURE_USE, Receive Time, Serial Number, Type, Content/Threat Type, FUTURE_USE, Generated Time, Virtual System, Event ID, Object, FUTURE_USE, FUTURE_USE, Module, Severity, Description, Sequence Number, Action Flags, Device Group Hierarchy Level 1, Device Group Hierarchy Level 2, Device Group Hierarchy Level 3, Device Group Hierarchy Level 4, Virtual System Name, Device Name, FUTURE_USE, FUTURE_USE, High Resolution Timestamp
    Field Name
    Description
    Receive Time (receive_time or cef-formatted-receive_time)
    Time the log was received at the management plane.
    Serial Number (serial)
    Serial number of the firewall that generated the log.
    Type (type)
    Specifies the type of log; value is SYSTEM.
    Content/Threat Type (subtype)
    Subtype of the system log; refers to the system daemon generating the log; values are crypto, dhcp, dnsproxy, dos, general, global-protect, ha, hw, nat, ntpd, pbf, port, pppoe, ras, routing, satd, sslmgr, sslvpn, userid, url-filtering, vpn.
    Generated Time (time_generated or cef-formatted-time_generated)
    Time the log was generated on the dataplane.
    Virtual System (vsys)
    Virtual System associated with the configuration log.
    Event ID (eventid)
    String showing the name of the event.
    Object (object)
    Name of the object associated with the system event.
    Module (module)
    This field is valid only when the value of the Subtype field is general. It provides additional information about the sub-system generating the log; values are general, management, auth, ha, upgrade, chassis.
    Severity (severity)
    Severity associated with the event; values are informational, low, medium, high, critical.
    Description (opaque)
    Detailed description of the event, up to a maximum of 512 bytes.
    Sequence Number (seqno)
    A 64-bit log entry identifier incremented sequentially; each log type has a unique number space.
    Action Flags (actionflags)
    A bit field indicating if the log was forwarded to Panorama.
    Device Group Hierarchy (dg_hier_level_1 to dg_hier_level_4)
    A sequence of identification numbers that indicate the device group’s location within a device group hierarchy. The firewall (or virtual system) generating the log includes the identification number of each ancestor in its device group hierarchy. The shared device group (level 0) is not included in this structure.
    If the log values are 12, 34, 45, 0, it means that the log was generated by a firewall (or virtual system) that belongs to device group 45, and its ancestors are 34, and 12. To view the device group names that correspond to the value 12, 34 or 45, use one of the following methods:
    API query: 
    /api/?type=op&cmd=<show><dg-hierarchy></dg-hierarchy></show>
    Virtual System Name (vsys_name)
    The name of the virtual system associated with the session; only valid on firewalls enabled for multiple virtual systems.
    Device Name (device_name)
    The hostname of the firewall on which the session was logged.
    High Resolution Timestamp (high_res_timestamp)
    Time in milliseconds the log was received at the management plane.
    The format for this new field is YYYY-MM-DDThh:ss:sssTZD:
    • YYYY—Four digit year
    • MM—Two-digit month
    • DD—Two-digit day of the month (01 through 31)
    • T—Indicator for the beginning of the timestamp
    • hh—Two-digit hour using 24-hour time (00 through 23)
    • mm—Two-digit minute (00 through 59)
    • ss—Two-digit second (00 through 60)
    • sss—One or more digits for millisecond
    • TZD—Time zone designator (+hh:mm or -hh:mm)
    The High Resolution Timestamp is supported for logs received from managed firewalls running PAN-OS 10.1 and later releases. Logs received from managed firewalls running PAN-OS 9.1 and earlier releases display a 1969-12-31T16:00:00:000-8:00 timestamp regardless of when the log was received.
