Numeral formatting

Numeral formatting in Kibana is done through a pattern-based syntax. These patterns express common number formats in a concise way, similar to date formatting. While these patterns are originally based on Numeral.js, they are now maintained by Kibana.

Numeral formatting patterns are used in multiple places in Kibana, including:

The simplest pattern format is 0, and the default Kibana pattern is 0,0.[000]. The numeral pattern syntax expresses:

Number of decimal places
The . character turns on the option to show decimal places using a locale-specific decimal separator, most often . or ,. To add trailing zeroes such as 5.00, use a pattern like 0.00. To have optional zeroes, use the [] characters.
Thousands separator
The thousands separator , turns on the option to group thousands using a locale-specific separator. The separator is most often , or ., and sometimes .
Accounting notation
Putting parentheses around your format like (0.00) will use accounting notation to show negative numbers.

The display of these patterns is affected by the advanced setting format:number:defaultLocale. The default locale is en, but some examples will specify that they are using an alternate locale.

Most basic examples:

Input* Pattern Locale *Output
10000.23 0,0 en (English) 10,000
10000.23 0.0 en (English) 10000.2
10000.23 0,0.0 fr (French) 10 000,2
10000.23 0,0.000 fr (French) 10 000,230
10000.23 0,0[.]0 en (English) 10,000.2
10000.23 0.00[0] en (English) 10,000.23
-10000.23 (0) en (English) (10000)

Percentages

By adding the % symbol to any of the previous patterns, the value is multiplied by 100 and the % symbol is added in the place indicated.

The default percentage formatter in Kibana is 0,0.[000]%, which shows up to three decimal places.

Input* Pattern Locale *Output
0.43 0,0.[000]% en (English) 43.00%
0.43 0,0.[000]% fr (French) 43,00%
1 0% en (English) 100%
-0.43 0 % en (English) -43 %

Bytes and bits

The bytes and bits formatters will shorten the input by adding a suffix like GB or TB. Bytes and bits formatters include the following suffixes:

b
Bytes with binary values and suffixes. 1024 = 1KB
bb
Bytes with binary values and binary suffixes. 1024 = 1KiB
bd
Bytes with decimal values and suffixes. 1000 = 1kB
bitb
Bits with binary values and suffixes. 1024 = 1Kibit
bitd
Bits with decimal values and suffixes. 1000 = 1kbit

Suffixes are not localized with this formatter.

Input* Pattern Locale *Output
2000 0.00b en (English) 1.95KB
2000 0.00bb en (English) 1.95KiB
2000 0.00bd en (English) 2.00kB
3153654400000 0.00bd en (English) 3.15GB
2000 0.00bitb en (English) 1.95Kibit
2000 0.00bitd en (English) 2.00kbit

Currency

Currency formatting is limited in Kibana due to the limitations of the pattern syntax. To enable currency formatting, use the symbol $ in the pattern syntax. The number formatting locale will affect the result.

Input* Pattern Locale *Output
1000.234 $0,0.00 en (English) $1,000.23
1000.234 $0,0.00 fr (French) €1 000,23
1000.234 $0,0.00 chs (Simplified Chinese) ¥1,000.23

Duration formatting

Converts a value in seconds to display hours, minutes, and seconds.

Input* Pattern *Output
25 00:00:00 0:00:25
25 00:00 0:00:25
238 00:00:00 0:03:58
63846 00:00:00 17:44:06
-1 00:00:00 -0:00:01

Displaying abbreviated numbers

The a pattern will look for the shortest abbreviation for your number, and use a locale-specific display for it. The abbreviations aK, aM, aB, and aT can indicate that the number should be abbreviated to a specific order of magnitude.

Input* Pattern Locale *Output
2000000000 0.00a en (English) 2.00b
2000000000 0.00a ja (Japanese) 2.00十億
-5444333222111 0,0 aK en (English) -5,444,333,222 k
-5444333222111 0,0 aM en (English) -5,444,333 m
-5444333222111 0,0 aB en (English) -5,444 b
-5444333222111 0,0 aT en (English) -5 t

Ordinal numbers

The o pattern will display a locale-specific positional value like 1st or 2nd. This pattern has limited support for localization, especially in languages with multiple forms, such as German.

Input* Pattern Locale *Output
3 0o en (English) 3rd
34 0o en (English) 34th
3 0o es (Spanish) 2er
3 0o ru (Russian) 3.
