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.

Example: macros.device_component_down_cisco = 1
