This is my view map and reduce function:
server": {
"map": "function(doc) { if (doc.type ==
'performance_stats') emit([doc.test_id, doc.Hostname],null ) }",
"reduce": "function(keys, values) {return (null)}"
},
And it works on one of my other hosts running couchdb(older version).
Here is the response:
{"rows":[
{"key":["ViPR_1.1_test2","10.247.98.206"],"value":null},
{"key":["ViPR_1.1_test2","10.247.98.207"],"value":null},
{"key":["ViPR_1.1_test2","10.247.98.208"],"value":null},
{"key":["ViPR_1.1_test2","10.247.98.209"],"value":null},
{"key":["ViPR_1.1_test2","10.247.98.210"],"value":null}
]}

Make sure that the value your map function emits is a number, not a strings or
something else.
