This is an integration to parse certain logs from pfSense and OPNsense firewalls. It parses logs received over the network via syslog (UDP/TCP/TLS). pfSense natively only supports UDP. OPNsense supports all 3 transports.
Currently the integration supports parsing the Firewall, Unbound, DHCP Daemon, OpenVPN, IPsec, HAProxy, Squid, and PHP-FPM (Authentication) logs.
All other events will be dropped.
The HAProxy logs are setup to be compatible with the dashboards from the HAProxy integration. Install the HAProxy integration assets to use them.
pfSense Setup
- Navigate to Status -> System Logs, then click on Settings
- At the bottom check Enable Remote Logging
- (Optional) Select a specific interface to use for forwarding
- Input the agent IP address and port as set via the integration config into the field Remote log servers (e.g. 192.168.100.50:5140)
- Under Remote Syslog Contents select what logs to forward to the agent
- Select Everything to forward all logs to the agent or select the individual services to forward. Any log entry not in the list above will be dropped. This will cause additional data to be sent to the agent and Elasticsearch. The firewall, VPN, DHCP, DNS, and Authentication (PHP-FPM) logs are able to be individually selected. In order to collect HAProxy and Squid or other "package" logs, the Everything option must be selected.
OPNsense Setup
- Navigate to System -> Settings -> Logging/Targets
- Add a new Logging/Target (Click the plus icon)
- Transport = UDP or TCP or TLS
- Applications = Select a list of applications to send to remote syslog. Leave empty for all.
- Levels = Nothing Selected
- Facilities = Nothing Selected
- Hostname = IP of Elastic agent as configured in the integration config
- Port = Port of Elastic agent as configured in the integration config
- Certificate = Client certificate to use (when selecting a tls transport type)
- Description = Syslog to Elasticsearch
- Click Save
The module is by default configured to run with the udp
input on port 9001
.
Important
The pfSense integration supports both the BSD logging format (used by pfSense by default and OPNsense) and the Syslog format (optional for pfSense).
However the syslog format is recommended. It will provide the firewall hostname and timestamps with timezone information.
When using the BSD format, the Timezone Offset
config must be set when deploying the agent or else the timezone will default to the timezone of the agent. See https://<pfsense url>/status_logs_settings.php
and https://docs.netgate.com/pfsense/en/latest/monitoring/logs/settings.html for more information.
A huge thanks to a3ilson for the https://github.com/pfelk/pfelk repo, which is the foundation for the majority of the grok patterns and dashboards in this integration.

Exported fields
Field | Description | Type |
---|---|---|
@timestamp | Date/time when the event originated. This is the date/time extracted from the event, typically representing when the event was generated by the source. If the event source has no original timestamp, this value is typically populated by the first time the event was received by the pipeline. Required field for all events. | date |
client.address | Some event client addresses are defined ambiguously. The event will sometimes list an IP, a domain or a unix socket. You should always store the raw address in the .address field. Then it should be duplicated to .ip or .domain , depending on which one it is. | keyword |

destination.port | Port of the destination. | long |
dns.question.class | The class of records being queried. | keyword |
dns.question.name | The name being queried. If the name field contains non-printable characters (below 32 or above 126), those characters should be represented as escaped base 10 integers (\DDD). Back slashes and quotes should be escaped. Tabs, carriage returns, and line feeds should be converted to \t, \r, and \n respectively. | keyword |
dns.question.registered_domain | The highest registered domain, stripped of the subdomain. For example, the registered domain for "foo.example.com" is "example.com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last two labels will not work well for TLDs such as "co.uk". | keyword |
dns.question.subdomain | The subdomain is all of the labels under the registered_domain. If the domain has multiple levels of subdomain, such as "sub2.sub1.example.com", the subdomain field should contain "sub2.sub1", with no trailing period. | keyword |
dns.question.top_level_domain | The effective top level domain (eTLD), also known as the domain suffix, is the last part of the domain name. For example, the top level domain for example.com is "com". This value can be determined precisely with a list like the public suffix list (http://publicsuffix.org). Trying to approximate this by simply taking the last label will not work well for effective TLDs such as "co.uk". | keyword |
dns.question.type | The type of record being queried. | keyword |
dns.type | The type of DNS event captured, query or answer. If your source of DNS events only gives you DNS queries, you should only create dns events of type dns.type:query . If your source of DNS events gives you answers as well, you should create one event per query (optionally as soon as the query is seen). And a second event containing all query details as well as an array of answers. | keyword |
ecs.version | ECS version this event conforms to. ecs.version is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |
error.message | Error message. | match_only_text |
event.action | The action captured by the event. This describes the information in the event. It is more specific than event.category . Examples are group-add , process-started , file-created . The value is normally defined by the implementer. | keyword |
event.category | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. event.category represents the "big buckets" of ECS categories. For example, filtering on event.category:process yields all events relating to process activity. This field is closely related to event.type , which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. | keyword |
event.dataset | Event dataset | constant_keyword |
event.duration | Duration of the event in nanoseconds. If event.start and event.end are known this value should be the difference between the end and start time. | long |
event.id | Unique ID to describe the event. | keyword |
event.ingested | Timestamp when an event arrived in the central data store. This is different from @timestamp , which is when the event originally occurred. It's also different from event.created , which is meant to capture the first time an agent saw the event. In normal conditions, assuming no tampering, the timestamps should chronologically look like this: @timestamp < event.created < event.ingested . | date |
event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. event.kind gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data is coming in at a regular interval or not. | keyword |
event.module | Event module | constant_keyword |
event.original | Raw text message of entire event. Used to demonstrate log integrity or where the full log message (before splitting it up in multiple parts) may be required, e.g. for reindex. This field is not indexed and doc_values are disabled. It cannot be searched, but it can be retrieved from _source . If users wish to override this and index this field, please see Field data types in the Elasticsearch Reference . | keyword |
event.outcome | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. event.outcome simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of event.outcome , according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with event.type:info , or any events for which an outcome does not make logical sense. | keyword |
event.provider | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing). | keyword |
event.reason | Reason why this event happened, according to the source. This describes the why of a particular action or outcome captured in the event. Where event.action captures the action from the event, event.reason describes why that action was taken. For example, a web proxy with an event.action which denied the request may also populate event.reason with the reason why (e.g. blocked site ). | keyword |
event.timezone | This field should be populated when the event's timestamp does not include timezone information already (e.g. default Syslog timestamps). It's optional otherwise. Acceptable timezone formats are: a canonical ID (e.g. "Europe/Amsterdam"), abbreviated (e.g. "EST") or an HH:mm differential (e.g. "-05:00"). | keyword |
event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. event.type represents a categorization "sub-bucket" that, when used along with the event.category field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |
haproxy.backend_name | Name of the backend (or listener) which was selected to manage the connection to the server. | keyword |

host.id | Unique host id. As hostname is not always unique, use values that are meaningful in your environment. Example: The current usage of beat.name . | keyword |
host.ip | Host ip addresses. | ip |
host.mac | Host mac addresses. | keyword |
host.name | Name of the host. It can contain what hostname returns on Unix systems, the fully qualified domain name, or a name specified by the user. The sender decides which value to use. | keyword |

http.response.status_code | HTTP response status code. | long |
http.version | HTTP version. | keyword |
input.type | Type of Filebeat input. | keyword |
log.level | Original log level of the log event. If the source of the event provides a log level or textual severity, this is the one that goes in log.level . If your source doesn't specify one, you may put your event transport's severity here (e.g. Syslog severity). Some examples are warn , err , i , informational . | keyword |
log.source.address | Source address of the syslog message. | keyword |
log.syslog.priority | Syslog numeric priority of the event, if available. According to RFCs 5424 and 3164, the priority is 8 * facility + severity. This number is therefore expected to contain a value between 0 and 191. | long |
message | For log events the message field contains the log message, optimized for viewing in a log viewer. For structured logs without an original message field, other fields can be concatenated to form a human-readable summary of the event.

network.bytes | Total bytes transferred in both directions. If source.bytes and destination.bytes are known, network.bytes is their sum. | long |
network.community_id | A hash of source and destination IPs and ports, as well as the protocol used in a communication. This is a tool-agnostic standard to identify flows. Learn more at https://github.com/corelight/community-id-spec. | keyword |
network.direction | Direction of the network traffic. When mapping events from a host-based monitoring context, populate this field from the host's point of view, using the values "ingress" or "egress". When mapping events from a network or perimeter-based monitoring context, populate this field from the point of view of the network perimeter, using the values "inbound", "outbound", "internal" or "external". Note that "internal" is not crossing perimeter boundaries, and is meant to describe communication between two hosts within the perimeter. Note also that "external" is meant to describe traffic between two hosts that are external to the perimeter. This could for example be useful for ISPs or VPN service providers. | keyword |
