Description
The output for createIndexes used to look like this before removing MMAPv1:
|
|
"inprog" : [
|
{
|
"host" : "delphi:28022",
|
"desc" : "repl index builder 1",

It is basically only intelligible because of the ns field value of "<db>.system.indexes", and that's only to engineers, not users.
After SERVER-36015, it looks like this:
{
|
"inprog" : [
|
{
|
"host" : "delphi:28022",
|
"desc" : "repl index builder 1",
|
"active" : true,

|
"opid" : 223,
|
"op" : "none",
|
"ns" : "",
|
"command" : {
|
"v" : 2,
|
"key" : {
|
"x" : 1
|
},
|
"name" : "x_1",
|
"background" : true,
|
"ns" : "test.index_bigkeys_downgrade_during_index_build"
|
},
|
"msg" : "Index Build (background) Index Build (background): 0/10 0%",
|
"progress" : {

"done" : 0,
|
"total" : 10
|
},
|

This entry should say "createIndexes" somewhere. The code starting point to investigate how currentOp puts this entry together – and thus where to put the code to improve it – is here: I tracked that code starting from here, but I didn't go any further.
