Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

perfdata-parser

Parses nagios perfdata into a json object.

Command Line Tool

# output json of a nagios plugin's perfdata
a-nagios-plugin | perfdata-parser

# using the "flatten" structure instead
# can also use the short option -f
a-nagios-plugin | perfdata-parser --flatten

# pretty print of the json output
# short option is -p
# note you can mix and match --flatten and --pretty
a-nagios-plugin | perfdata-parser --flatten --pretty

If there are any parsing errors the command will output the error to stderr. Note that if there is no perfdata to parse, it returns a json object of null with no error; this will look like a string of 'null'

Javascript API Usage

var perfparser = require('perfdata-parser')

perfparser(`OK - some status msg | 'some label'=0%;1;2;3;4
    more lines of status
    fdasf
    fdsa
    last line - fgfga | another_label=100
`, { flatten: false, throwErr: false })

perfdata-parser now takes an optional option object with the following properties.

  • flatten - if truthy, returns an array of objects instead, see example below.
  • throwErr - throw parsing errors instead of returning undefined.

Returns

Returns object with keys for each label: eg:

'some label'=0%;1;2;3;4

Becomes

{ '\'some label\'': {
        oum: '%',
        value: 0,
        warn: 1,
        crit: 2,
        min: 3,
        max: 4
    }
}

or if the flatten option is enabled

[{  
    label: '\'some label\'',
    oum: '%',
    value: 0,
    warn: 1,
    crit: 2,
    min: 3,
    max: 4
}]
