# wtstats template

This directory contains the code to generate the `wtstats.html.template` file needed by the Python script `wtstats.py`.

The template is generated as a node.js "single page" application using several open source frameworks, see Dependencies below. The `wtstats.py` Python script parses stats files, transforms the data and inserts it as JSON into the template. The resulting HTML page can be openend in the browser.

### Build Process

To build the template, you need `npm` (node package manager). `npm` is included in the Node.js packages and source, which you can get at [http://nodejs.org/download/](). On Ubuntu, you can also install `npm` via `sudo apt-get install npm`. On AWS Linux, you can install `npm` via `sudo yum install npm --enablerepo=epel`.

Once you have `npm` installed, follow these steps: 

1. change into the `./tools/template` directory (where this `README.md` is located)
2. run `npm install` to install all missing dependencies. 
3. run `npm run build` to build the template. 

The build script packs everything into a single HTML file and copies it to its parent folder as `./tools/wtstats.html.template`. 

### Usage

Call the `wtstats.py` Python script located in the `./tools` directory with a stats file as argument. The `./tools/test` subfolder contains a small example stats file to test: 

```
python wtstats.py ./test/WiredTigerStat.fixture
```

The script will create `wtstats.html` in the working directory, which can be viewed with any modern browser (latest versions of Chrome, Safari, FireFox, Internet Explorer supported).

For more information about _wtstats_ usage, check out the [wtstats documentation](https://github.com/wiredtiger/wiredtiger/wiki/WiredTiger-statistics) on the WiredTiger wiki.
