Puts continuous numerical values into discrete sets, or bins, by adjusting the value of <field> so that all of the items in a particular set have the same value.
bin command is automatically called by the
chart and the
timechart commands. Use the
bin command for only statistical operations that the
chart and the
timechart commands cannot process. Do not use the
bin command if you plan to export all events to CSV or JSON file formats.
The required syntax is in bold.
- <field> [AS <newfield>]
- Syntax: <field>
- Description: Specify a field name.
- Syntax: bins | minspan | span | <start-end> | aligntime
- Description: Discretization options. See the Bins options section in this topic for the syntax and description for each of these options.
- Syntax: <string>
- Description: A new name for the field.
- Syntax: bins=<int>
- Description: Sets the maximum number of bins to discretize into.
- Syntax: minspan=<span-length>
- Description: Specifies the smallest span granularity to use automatically inferring span from the data time range.
- Syntax: span = <log-span> | <span-length>
- Description: Sets the size of each bin, using a span length based on a logarithm-based span or based on time.
When a <span-length> of a day or more is used, the span is aligned to midnight in the timezone of the user.
- Syntax: start=<num> | end=<num>
- Description: Sets the minimum and maximum extents for numerical bins. The data in the field is analyzed and the beginning and ending values are determined. The start and end arguments are used when a span value is not specified.
- You can use the start or end arguments only to expand the range, not to shorten the range. For example, if the field represents seconds the values are from 0-59. If you specify a span of 10, then the bins are calculated in increments of 10. The bins are 0-9, 10-19, 20-29, and so forth. If you do not specify a span, but specify end=1000, the bins are calculated based on the actual beginning value and 1000 as the end value.
- If you set end=10 and the values are >10, the end argument has no effect.
- Syntax: aligntime=(earliest | latest | <time-specifier>)
- Description: Align the bin times to something other than base UTC time (epoch 0). The
aligntimeoption is valid only when doing a time-based discretization. Ignored if
spanis in days, months, or years.
- Syntax: [<num>]log[<num>]
- Description: Sets to log-based span. The first number is a coefficient. The second number is the base. If the first number is supplied, it must be a real number >= 1.0 and < base. Base, if supplied, must be real number > 1.0 (strictly greater than 1).
- Example: span=2log10
- Syntax: <int>[<timescale>]
- Description: A span of each bin. If discretizing based on the
_timefield or used with a timescale, this is treated as a time range. If not, this is an absolute bin length.
- Syntax: <sec> | <min> | <hr> | <day> | <month> | <subseconds>
- Description: Time scale units. If discretizing based on the
- Default: sec
Time scale Syntax Description <sec> s | sec | secs | second | seconds Time scale in seconds. <min> m | min | mins | minute | minutes Time scale in minutes. <hr> h | hr | hrs | hour | hours Time scale in hours. <day> d | day | days Time scale in days. <month> mon | month | months Time scale in months. <subseconds> us | ms | cs | ds Time scale in microseconds (us), milliseconds (ms), centiseconds (cs), or deciseconds (ds)
bucket command is an alias for the
bin command is usually a dataset processing command. If the
span argument is specified with the command, the
bin command is a streaming command. See Command types.
Subsecond bin time spans
span timescales—time spans that are made up of deciseconds (ds), centiseconds (cs), milliseconds (ms), or microseconds (us)—should be numbers that divide evenly into a second. For example, 1s = 1000ms. This means that valid millisecond
span values are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 200, 250, or 500ms. In addition,
span = 1000ms is not allowed. Use
span = 1s instead.
Return the average "thruput" of each "host" for each 5 minute time span.
... | bin _time span=5m | stats avg(thruput) by _time host
Bin search results into 10 bins, and return the count of raw events for each bin.
... | bin size bins=10 | stats count(_raw) by size
Create bins with an end value larger than you need, ensure that all possible values are included.
... | bin amount end=1000
Align the time bins to 3am (local time). Set the span to 12h. The bins will represent 3am - 3pm, then 3pm - 3am (the next day), and so on.
...| bin _time span=12h aligntime=@d+3h
Align the bins to the specific UTC time of 1500567890.
...| bin _time aligntime=1500567890
