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
}]
