# gotraceanlyzer

Command gotraceanalyzer turns golang tracebacks into useful summaries.

If you ever starred at a go panic that showed thousands of active goroutines,

this tool will help you to make more sense of it.

Summaries are created by grouping goroutines that share a common scheduler

state and trace (as determined by file locations) together.

## Install

```bash

$ go get github.com/felixge/gotraceanalyzer

```

## Usage

Analyze a traceback from a file:

```bash

$ gotraceanalyzer mypanic.txt

```

Or use stdin:

```bash

$ gotraceanalyzer < mypanic.txt

```

## Example

``` bash

$ curl -s https://raw.githubusercontent.com/felixge/gotraceanalyzer/master/example/output.txt | gotraceanalyzer
