Rules that decide which log messages are kept and where they go. Each rule selects messages by their topics, and optionally by a regular expression, and passes them to an action from /system/logging/action. The default rules pass info, error and warning messages to the memory action and critical messages to echo; other messages, for example debug, are not logged until a rule asks for them. See Log.
| Flag | Name | Description |
|---|---|---|
X | disabled | The rule is disabled. |
I | invalid | The rule is invalid. |
* | default | One of the four default rules: info, error and warning to memory, critical to echo. |
Y | managed |
| Argument | Type | Description |
|---|---|---|
topics | multi { array-id, array-id, topic: super { ! , topic: enum } } | Topics a message must carry to match. A message matches only when it has every topic listed: topics=dhcp,debug matches DHCP debug messages, not all DHCP messages and all debug messages. To log several topics, add one rule per topic. A rule without topics matches every message, debug messages included. ! before a topic excludes the messages that carry it, for example topics=ntp,debug,!packet logs NTP debug messages without the packet dumps. The topics are described on the Log page. The router accepts: account, acme-client, amt, async, backup, bfd, bgp, bridge, calc, caps, certificate, clock, container, critical, ddns, debug, dhcp, discover, disk, dns, dot1x, dude, e-mail, error, event, evpn, fetch, firewall, gps, gsm, health, hotspot, igmp-proxy, info, interface, ipsec, iscsi, isdn, isis, kvm, l2tp, ldp, lora, lte, manager, mme, mpls, mqtt, mvrp, natpmp, netinstall, netwatch, ntp, ospf, ovpn, packet, pim, poe-in, poe-out, pon, ppp, pppoe, pptp, ptp, queue, radius, radvd, raw, read, rip, route, rpki, rproxy, rsvp, script, sertcp, simulator, smb, snmp, socksify, ssh, ssld, sstp, state, store, stp, system, telephony, tftp, timer, tr069, update, upnp, ups, vpls, vrrp, warning, watchdog, web-proxy, wiliot, wireguard, wireless, write, zerotier. |
prefix | string | Text added in front of every message the rule passes, as <prefix>: <message>. The prefix is part of the stored and of the sent message. |
regex | string | Regular expression matched against the message text, followed by the message's extra fields. When it does not match, the rule does not pass the message, even when the topics match. |
action | enum | Action from /system/logging/action that receives the matching messages. Every rule that matches passes the message to its own action; when two rules pass the same message to one action, the action receives it once. Default: memory. |
