Macros
Macros are shorthands to either portion of rules or pure SQL enhanced with placeholders.
You can define your own macros in your config.php.
Example macro-implementation of Debian-Devices
$config['alert']['macros']['rule']['is_debian'] = 'devices.features ~ "@debian@"';
And in the Rule:
... macros.is_debian = 1 ...
This Example-macro is a Boolean-macro, it applies a form of filter to the set of results defined by the rule.
All macros that are not unary should return Boolean.
Device (Boolean)
Entity: macros.device
Description: Only select devices that aren't deleted, ignored or disabled.
Source: (devices.disabled = 0 AND devices.ignore = 0)
Device is up (Boolean)
Entity: macros.device_up
Description: Only select devices that are up.
Implies: macros.device
Source: (devices.status = 1 AND macros.device)
Device is down (Boolean)
Entity: macros.device_down
Description: Only select devices that are down.
Implies: macros.device
Source: (devices.status = 0 AND macros.device)
Port (Boolean)
Entity: macros.port
Description: Only select ports that aren't deleted, ignored or disabled.
Source: (ports.deleted = 0 AND ports.ignore = 0 AND ports.disabled = 0)
Port is up (Boolean)
Entity: macros.port_up
Description: Only select ports that are up and also should be up.
Implies: macros.port
Source: (ports.ifOperStatus = up AND ports.ifAdminStatus = up AND macros.port)
Port is down (Boolean)
Entity: macros.port_down
Description: Only select ports that are down.
Implies: macros.port
Source: (ports.ifOperStatus != "up" AND ports.ifAdminStatus != "down" AND macros.port)
Port-Usage in Percent (Decimal)
Entity: macros.port_usage_perc
Description: Return port-usage (max value of in and out) in percent.
Source: ((SELECT IF(ports.ifOutOctets_rate>ports.ifInOctets_rate, ports.ifOutOctets_rate, ports.ifInOctets_rate)*8) / ports.ifSpeed)*100
Time
Now (Datetime)
Entity: macros.now
Description: Alias of MySQL's NOW()
Source: NOW()
Past N Minutes (Datetime)
Entity: macros.past_$m
Description: Returns a MySQL Timestamp dated $ Minutes in the past. $ can only be a supported Resolution.
Example: macros.past_5m is Last 5 Minutes.
Resolution: 5,10,15,30,60
Source: DATE_SUB(NOW(),INTERVAL $ MINUTE)
Sensors (Boolean)
Entity: macros.sensor
Description: Only select sensors that aren't ignored.
Source: (sensors.sensor_alert = 1)
Entity: macros.sensor_port_link = 1
Description: Only selects sensors that have a port linked to them, the port is up and the device is up.
Source: (sensors.entity_link_type = "port" AND sensors.entity_link_index = ports.ifIndex AND macros.port_up AND macros.device_up))
State Sensors (Boolean)
Entity: macros.state_sensor_ok, macros.state_sensor_warning, macros.state_sensor_critical, macros.state_sensor_unknown
Description: Select state sensors by their generic status ok (0), warning (1), critical (2), unknown (3)
Source: (sensors.sensor_current = state_translations.state_value AND state_translations.state_generic_value = 2)
Misc (Boolean)
Packet Loss
Entity: (macros.packet_loss_5m)
Description: Packet loss % value for the device within the last 5 minutes. BROKEN, only return 100 (down) or 0.
Example: macros.packet_loss_5m > 50
Entity: (macros.packet_loss_15m)
Description: Packet loss % value for the device within the last 15 minutes. BROKEN, only return 100 (down) or 0.
Example: macros.packet_loss_15m > 50
Ports in usage perc (Int)
Entity: ((ports.ifInOctets_rate*8)/ports.ifSpeed)*100
Description: Port in used more than 50%
Example: `macros.port_in_usage_perc > 50
Ports out usage perc (Int)
Entity: ((ports.ifOutOctets_rate*8)/ports.ifSpeed)*100
Description: Port out used more than 50%
Example: `macros.port_out_usage_perc > 50
Ports now down (Boolean)
Entity: ports.ifOperStatus != ports.ifOperStatus_prev AND ports.ifOperStatus_prev = "up" AND ports.ifAdminStatus = "up"
Description: Ports that were previously up and have now gone down.
Example: macros.port_now_down = 1
Port has xDP neighbour (Boolean)
Entity: %macros.port AND %links.local_port_id = %ports.port_id
Description: Ports that have an xDP (lldp, cdp, etc) neighbour.
Example: macros.port_has_xdp_neighbours = 1
Port has xDP neighbour already known in LibreNMS (Boolean)
Entity: %macros.port_has_neighbours AND (%links.remote_port_id IS NOT NULL)
Description: Ports that have an xDP (lldp, cdp, etc) neighbour that is already known in libreNMS.
Example: macros.port_has_xdp_neighbours_device = 1
Device component down [JunOS]
Entity: sensors.sensor_class = "state" AND sensors.sensor_current != "6" AND sensors.sensor_type = "jnxFruState" AND sensors.sensor_current != "2"
Description: Device component is down such as Fan, PSU, etc for JunOS devices.
Example: macros.device_component_down_junos = 1
Device component down [Cisco]
Entity: sensors.sensor_current != 1 AND sensors.sensor_current != 5 AND sensors.sensor_type ~ "^cisco.*State$"
Description: Device component is down such as Fan, PSU, etc for Cisco devices.
