title: Tridium Niagara Station: Cross-Probe Special State

description:
 This check merges the probe tables below .1.3.6.1.4.1.4131.1.6.21 and
 .1.3.6.1.4.1.4131.1.6.22 of a Tridium Niagara station and evaluates each
 probe with an optional cross-probe rule. Detection fires when the device
 sysObjectID starts with .1.3.6.1.4.1.4131.1.

 With a configured rule the check looks at another field: if that field has
 a given state, a target state is required on this probe, otherwise an
 alternative target state is required. If the actual state differs from the
 required one the service goes {CRIT}. Alternatively a plain allow list of
 states can be configured. Without configuration the service is always
 {OK}. Numeric values additionally yield a {value} metric.

 The behaviour is configured via the rule "Tridium Special".

discovery:
 One service is created for each probe found in the merged tables.

item:
 The probe (sensor) name as reported by the device.
