Abstract: The Combined Array for Research in Millimeter-wave Astronomy (CARMA) will be the combination of the BIMA, OVRO, and SZA millimeter arrays, at a new high elevation site (7200', 2200 m). With first light scheduled for 2005, CARMA will be the first heterogeneous millimeter array, combining antennas with diameters of 3.5, 6.1 and 10.4 meters.

CARMA's monitoring system (CAM), is designed to collect monitor data periodically from a set of heterogenous systems and organize these monitor points hierarchically. It allows for the collection/collation of sampled values from arbitrary monitor points and the storage of such monitor point values in files and databases. Monitor points may be mapped to multiple hierarchies, for example, physical hierarchies like antennas, receivers, and drives, or logical hierarchies like sub-arrays and antennas.

The monitor system was designed to accommodate monitor points associated with state machines, physical quantities (such as voltages), complex quantities (such as phases) and logical quantities like process health. It is also designed to help identify and isolate problems quickly, especially during integration at the new high site.
