Sources the agent reads on the host, and listeners for devices that cannot run one.
-
filetail Core
Tails plain-text log files (application logs, web server logs, Kubernetes container logs) and forwards each line as an event, surviving file rotation and agent restarts.
-
http_in Core
Accepts log lines pushed over HTTP(S), for sources such as webhooks, IoT/edge devices and app log shippers that cannot run the agent or speak syslog.
-
journald Core
Reads the Linux systemd journal and forwards each entry as an event, resuming exactly where it left off after a restart.
-
syslog_in Core
Listens for incoming syslog (RFC 5424/3164 over TCP/UDP, or a local unix socket) so the agent can act as a gateway for devices that cannot run an agent themselves.
-
bsm_audit Apex
Collects the Solaris BSM audit trail — logins, privilege use and file changes — decoded with the operating system's own praudit, so each record arrives with the user, process and session that caused it.
-
etw Apex
Streams Windows ETW (Event Tracing for Windows) kernel and application telemetry in real time, capturing high-volume activity such as process creation, network connections and DNS that never reaches the Windows Event Log.
-
linux_audit Apex
Collects Linux kernel audit records - process executions, file-access watches, logins, privilege changes - reassembled into one structured event per audit event.
-
modbus_in Apex
Polls Modbus TCP/RTU industrial devices (PLCs, RTUs, meters) and emits events only on meaningful register changes, threshold crossings or device outages, never a raw telemetry stream. Read-only by construction.
-
mqtt_in Apex
Subscribes to an MQTT broker and turns each published message into an event, the common ingest shape for IoT/edge sensors and devices.
-
oslog Apex
Reads the macOS unified log, backfilling the gap since the agent's last run and then following new entries live.
-
relay_in Apex
Receives events over the agent's own acknowledged relay transport, so a gateway agent can concentrate traffic from edge agents with guaranteed delivery instead of best-effort TCP.
-
snmptrap_in Apex
Listens for SNMP traps and informs (v1/v2c/v3) from network and OT devices - switches, firewalls, UPSes, PLC gateways - and turns each notification into an event.
-
windows_eventlog Apex
Collects the Windows Event Log, the OS's structured record of system, security and application activity including Sysmon, with live subscription and resumable checkpoints.
-
wmi Apex
Polls Windows Management Instrumentation (WMI) via WQL queries for system-inventory and live-state data: running services, installed hotfixes, disk usage, hardware.
