Problem starting monitor-dashboard

[benjamincochran]

I've added monitor to my app file:

bc-comp:myproject-node benjamincochran$ cat app.js
"use strict";
[snip]
// monitoring
require('monitor').start();
[etc]

... and that seems to be working correctly, in that I can connect from the REPL:

bc-comp:myproject-node benjamincochran$ node
> var Monitor = require('monitor');
undefined
> var processMonitor = new Monitor({probeClass:'Process'});
undefined
> processMonitor.connect();
undefined
> processMonitor.get('freemem');
31395840
> processMonitor.get('freemem');
31346688

I've also installed monitor-dashboard, which seems to have worked, but with warnings:

bc-comp:myproject-node benjamincochran$ npm install monitor-dashboard
npm WARN package.json myproject-node@0.0.7 No README data
npm WARN engine connect@1.7.3: wanted: {"node":">= 0.4.1 < 0.7.0"} (current: {"node":"0.10.32","npm":"2.1.2"})

├── backbone-callbacks@0.1.7 (backbone@0.9.10, underscore@1.4.4)
└── core-monitor@0.6.3

... but when I try to actually start it up, I get nuthin', zilch, nada:

bc-mycomp:myproject-node benjamincochran$ npm start monitor-dashboard
bc-mycomp:myproject-node benjamincochran$ 

What have I done wrong? I'm on OSX, 10.9.2.

Not sure why it's not starting for you. Try this:

1) cd to node_modules/monitor-dashboard 2) run node monitor.js

That's essentially what npm start monitor-dashboard does. Maybe there'll be better debugging information about what went wrong.

That works. I can even run it from the local directory:

bc-comp:myproject-node benjamincochran$ node node_modules/monitor-dashboard/monitor.js

Very strange.

strange. is there an npm error file output in your local directory when you run npm start monitor-dashboard ?

Hi. I have faced with the same problem with launching tool on Windows :

npm start monitor-dashboard

Output:

This sounds like a difference in npm start behavior, either a windows difference or an npm version difference. It seems to say it's missing the start script, but if you examine the package.json it should be there.
