Measurements system view functions

_design/measurements

This view is only used in the measurements subsystem.

Both views find only measurement documents ("type" === "measurement").

measurements

Emits [measurement_name, Y, M, D, H, M, S] as key and the log as value.

• map

  function(doc) {
   if (!doc.type || !doc.timestamp) return;
   if (doc.type !== "measurement") return;
   var then = new Date(Date.parse(doc.timestamp));
   var the_log = doc.log || "No log";
   emit([doc.measurement_name || "Unknown",
         then.getUTCFullYear(), then.getUTCMonth(),
         then.getUTCDate(), then.getUTCHours(),
         then.getUTCMinutes(), then.getUTCSeconds()], the_log.trim());
  }

• reduce: _count

measurements_label

Emits [Y, M, D, H, M, S, measurement_namee] as key and the log as value.

• map

  function(doc) {
   if (!doc.type || !doc.timestamp) return;
   if (doc.type !== "measurement") return;
   var then = new Date(Date.parse(doc.timestamp));
   var the_log = doc.log || "No log";
   emit([then.getUTCFullYear(), then.getUTCMonth(),
         then.getUTCDate(), then.getUTCHours(),
         then.getUTCMinutes(), then.getUTCSeconds(),
         doc.measurement_name || "Unknown"], the_log.trim());
