corevis
=======

Generate HTML based on information gathered with `mdb(1)` from
a [node.js](http://nodejs.org) core dump

Example: http://us-east.manta.joyent.com/devops@voxer.com/public/corevis/example.html

Installation
------------

[sudo] npm install -g corevis

Usage
-----

At Voxer, we use commands similar to the ones below to ensure that all
core dumps go to a specific directory

mkdir /core
    coreadm -g /core/core.%f.%p -G all -e global -d process -e global-setid -d proc-setid -I all -e log

Run any of the [examples](examples) to generate a core dump, then use `corevis`
to make an HTML file with analysis.

[root@test1 ~/node-corevis]# node examples/big-objects.js
    pid 9986
    Abort (core dumped)
    [root@test1 ~/node-corevis]# ./corevis.js /core/core.node.9986 > example.html
