Function Details

get_round_trip/2

get_round_trip(GPid :: comm:mypid(), Iterations :: pos_integer()) ->
                  float()

Simple round-trip benchmark to an arbitrary gen_component.

dump/0

dump() -> [{Fun :: mfa(), FunExecCount :: pos_integer()}]

Returns a list of all currently executed functions and the number of instances for each of them.

dump2/0

dump2() -> [{PID :: pid(), [pos_integer() | mfa() | any()]}]

Returns information about all processes' memory usage.

dump3/0

dump3() ->
         [{PID :: pid(),
           [Mem |
            MsgQLength |
            StackSize |
            HeapSize |
            Messages |
            Fun]}]

```
Mem = non_neg_integer()
```
```
MsgQLength = non_neg_integer()
```
```
StackSize = non_neg_integer()
```
```
HeapSize = non_neg_integer()
```
```
Messages = [atom()]
```
```
Fun = mfa()
```

Returns various data about all processes.

dumpX/1

dumpX(ItemInfo :: [ItemInfo :: atom(), ...]) -> [tuple(), ...]

Returns various data about all processes.

dumpX/2

dumpX(ItemInfo :: [ItemInfo :: atom(), ...],
      ValueFun :: fun((atom(), term()) -> term())) ->
         [tuple(), ...]

Returns various data about all processes.

topDumpX/1

topDumpX(Keys :: Keys | Seconds | ValueFun) ->
            [{pid(), [Reductions | RegName | term(), ...]}, ...]

```
Keys = [ItemInfo :: atom()]
```
```
Seconds = pos_integer()
```

ValueFun = fun((atom(), term()) -> term())

```
Reductions = non_neg_integer()
```
```
RegName = atom()
```

Convenience wrapper to topDumpX/3.

topDumpX/3

topDumpX(Keys, ValueFun, Seconds) ->
            [{pid(), [Reductions | RegName | term(), ...]}, ...]

```
Keys = [ItemInfo :: atom()]
```
```
Seconds = pos_integer()
```

ValueFun = fun((atom(), term()) -> term())

```
Reductions = non_neg_integer()
```
```
RegName = atom()
```

Gets the number of reductions for each process within the next Seconds and dumps some process data defined by Keys (sorted by the number of reductions).

topDumpXEvery/3

topDumpXEvery(Keys :: Keys | Seconds | ValueFun,
              Subset :: pos_integer(),
              StopAfter :: pos_integer()) ->
                 timer:tref()

```
Keys = [ItemInfo :: atom()]
```
```
Seconds = pos_integer()
```

ValueFun = fun((atom(), term()) -> term())

Convenience wrapper to topDumpXEvery/5.

topDumpXEvery/5

topDumpXEvery(Keys,
              ValueFun,
              Seconds,
              Subset :: pos_integer(),
              StopAfter :: pos_integer()) ->
                 timer:tref()

```
Keys = [ItemInfo :: atom()]
```
```
Seconds = pos_integer()
```

ValueFun = fun((atom(), term()) -> term())

Calls topDumpX/3 every Seconds and prints the top Subset processes with the highest number of reductions. Stops after StopAfter seconds.

topDumpXEvery_helper/4

topDumpXEvery_helper(Keys,
                     ValueFun,
                     Seconds,
