## msdumper

msdumper just periodically dumps `runtime.MemStats` to a file.

`go get github.com/rubyist/msdumper`

```go

import "github.com/rubyist/msdumper"

if err := msdumper.Start("memstats.dat", time.Second); err != nil {

  log.Fatal(err)

}

// Some time later, if you like ...

msdumper.Stop()

```

## msgraph

msgraph will use gnuplot to generate a graph from the data file.

`go install github.com/rubyist/msdumper/msgraph`

```

$ msgraph memstats.dat

```

This will output `graph.png` by default.

You can specify an output file and graph title:

```

$ msgraph -h

Usage of msgraph:

  -o="graph.png": output file

  -t="MemStats": graph titlep

```
