to the session. |
Session ID (sessionid) | Session ID of the session being logged. |
Repeat Count (repeatcnt) | Number of sessions with same Source IP,
Destination IP, Application, and Subtype seen within 5 seconds. |
Source Port (sport) | Source port utilized by the session. |
Destination Port (dport) | Destination port utilized by the session. |
NAT Source Port (natsport) | Post-NAT source port. |
NAT Destination Port (natdport) | Post-NAT destination port. |
Flags (flags) | 32-bit field that provides details on session;
this field can be decoded by AND-ing the values with the logged
value:
|
IP Protocol (proto) | IP protocol associated with the session. |
Action (action) | Action taken for the session; possible values
are:
|
Severity (severity) | Severity associated with the event; values
are informational, low, medium, high, critical. |
Sequence Number (seqno) | A 64-bit log entry identifier incremented
sequentially; each log type has a unique number space. This field
is not supported on PA-7000 Series firewalls. |
Action Flags (actionflags) | A bit field indicating if the log was forwarded
to Panorama. |
Source Location (srcloc) | Source country or Internal region for private
addresses; maximum length is 32 bytes. |
Destination Location (dstloc) | Destination country or Internal region for
private addresses. Maximum length is 32 bytes. |
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:
|
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. |
Tunnel ID (tunnelid) | ID of the tunnel being inspected or the
International Mobile Subscriber Identity (IMSI) ID of the mobile
user. |
Monitor Tag (monitortag) | Monitor name you configured for the Tunnel
Inspection policy rule or the International Mobile Equipment Identity
(IMEI) ID of the mobile device. |
Parent Session ID (parent_session_id) | ID of the session in which this session
is tunneled. Applies to inner tunnel (if two levels of tunneling)
or inside content (if one level of tunneling) only. |
Parent Start Time (parent_start_time) | Year/month/day hours:minutes:seconds that
the parent tunnel session began. |
Tunnel Type (tunnel) | Type of tunnel, such as GRE or IPSec. |
Bytes (bytes) | Number of bytes in the session. |
Bytes Sent (bytes_sent) | Number of bytes in the client-to-server
direction of the session. |

direction of the session. |

for the session. |
Packets Sent (pkts_sent) | Number of client-to-server packets for the
session. |
Packets Received (pkts_received) | Number of server-to-client packets for the
session. |
Maximum Encapsulation (max_encap) | Number of packets the firewall dropped because
the packet exceeded the maximum number of encapsulation levels configured
in the Tunnel Inspection policy rule (Drop packet if over maximum
tunnel inspection level). |
Unknown Protocol (unknown_proto) | Number of packets the firewall dropped because
the packet contains an unknown protocol, as enabled in the Tunnel
Inspection policy rule (Drop packet if unknown protocol inside tunnel). |
Strict Checking (strict_check) | Number of packets the firewall dropped because
the tunnel protocol header in the packet failed to comply with the
RFC for the tunnel protocol, as enabled in the Tunnel Inspection
policy rule (Drop packet if tunnel protocol fails strict
