description:
 This check monitors the fans of Arista Networks switches via the SNMP
 ENTITY-SENSOR-MIB. Sensors reporting their unit as RPM are treated as
 fans.

 Lower and upper levels for the fan speed can be configured via the rule
 "Fans" (default: lower levels 2000 / 1000 RPM, no upper levels). The
 sensor's own status is evaluated as well: status 1 (ok) is {OK}, status 2
 (unavailable) is {WARN}, status 3 (nonoperational) is {CRIT}, any other
 status is {UNKNOWN}.

discovery:
 One service is created for each sensor reporting its unit as RPM.

item:
 The entity description of the fan, with a leading "Fan " prefix stripped.
