SYNOPSIS¶
rare
[--color]
[--help|-h]
[--nocolor|--nc]
[--noformat|--nf]
[--notrim]
[--nounicode|--nu]
[--profile]=[value]
[--version|-v]
Usage:
rare [GLOBAL OPTIONS] command [COMMAND OPTIONS] [ARGUMENTS...]
GLOBAL OPTIONS¶
--color: Force-enable color output
--help, -h: show help
--nocolor, --nc: Disables color output
--noformat, --nf: Disable number formatting
--notrim: By default, rare will trim output text for in-place updates. Setting this flag will disable that
--nounicode, --nu: Disable usage of unicode characters
--profile="": Write application profiling information as part of execution. Specify base-name
--version, -v: print the version
COMMANDS¶
filter, f¶
Filter incoming results with search criteria, and output raw matches
--batch="": Specifies io batching size. Set to 1 for immediate input (default: 1000)
--extract, -e="": Expression that will generate the key to group by. Specify multiple times for multi-dimensions or use {$} helper (default: {0})
--follow, -f: Read appended data as file grows
--gunzip, -z: Attempt to decompress file when reading
--ignore, -i="": Ignore a match given a truthy expression (Can have multiple)
--line, -l: Output source file and line number
--match, -m="": Regex to create match groups to summarize on (default: .*)
--poll: When following a file, poll for changes rather than using inotify
--posix, -p: Compile regex as against posix standard
--readers, --wr="": Sets the number of concurrent readers (Infinite when -f) (default: 3)
--recursive, -R: Recursively walk a non-globbing path and search for plain-files
--reopen, -F: Same as -f, but will reopen recreated files
--workers, -w="": Set number of data processors (default: 3)
histogram, h, histo¶
Summarize results by extracting them to a histogram
--all, -a: After summarization is complete, print all histogram buckets
--atleast="": Only show results if there are at least this many samples (default: 0)
--bars, -b: Display bars as part of histogram
--batch="": Specifies io batching size. Set to 1 for immediate input (default: 1000)
--extra, -x: Alias for -b --percentage
--extract, -e="": Expression that will generate the key to group by. Specify multiple times for multi-dimensions or use {$} helper (default: {0})
--follow, -f: Read appended data as file grows
--gunzip, -z: Attempt to decompress file when reading
--ignore, -i="": Ignore a match given a truthy expression (Can have multiple)
--match, -m="": Regex to create match groups to summarize on (default: .*)
--num, -n="": Number of elements to display (default: 5)
--percentage: Display percentage of total next to the value
--poll: When following a file, poll for changes rather than using inotify
--posix, -p: Compile regex as against posix standard
--readers, --wr="": Sets the number of concurrent readers (Infinite when -f) (default: 3)
--recursive, -R: Recursively walk a non-globbing path and search for plain-files
--reopen, -F: Same as -f, but will reopen recreated files
--reverse: Reverses the display sort-order
--sortkey, --sk: Sort by key, rather than value
--workers, -w="": Set number of data processors (default: 3)
bargraph, b, bar, bars¶
Create a bargraph of the given 1 or 2 dimension data
--batch="": Specifies io batching size. Set to 1 for immediate input (default: 1000)
--extract, -e="": Expression that will generate the key to group by. Specify multiple times for multi-dimensions or use {$} helper (default: {0})
--follow, -f: Read appended data as file grows
--gunzip, -z: Attempt to decompress file when reading
--ignore, -i="": Ignore a match given a truthy expression (Can have multiple)
--match, -m="": Regex to create match groups to summarize on (default: .*)
--poll: When following a file, poll for changes rather than using inotify
--posix, -p: Compile regex as against posix standard
--readers, --wr="": Sets the number of concurrent readers (Infinite when -f) (default: 3)
--recursive, -R: Recursively walk a non-globbing path and search for plain-files
--reopen, -F: Same as -f, but will reopen recreated files
--reverse: Reverses the display sort-order
--stacked, -s: Display bargraph as stacked
--workers, -w="": Set number of data processors (default: 3)
analyze, a¶
Numerical analysis on a set of filtered data
--batch="": Specifies io batching size. Set to 1 for immediate input (default: 1000)
--extra, -x: Displays extra analysis on the data (Requires more memory and cpu)
--extract, -e="": Expression that will generate the key to group by. Specify multiple times for multi-dimensions or use {$} helper (default: {0})
--follow, -f: Read appended data as file grows
--gunzip, -z: Attempt to decompress file when reading
--ignore, -i="": Ignore a match given a truthy expression (Can have multiple)
--match, -m="": Regex to create match groups to summarize on (default: .*)
--poll: When following a file, poll for changes rather than using inotify
--posix, -p: Compile regex as against posix standard
--quantile, -q="": Adds a quantile to the output set. Requires --extra (default: 90,99,99.9)
--readers, --wr="": Sets the number of concurrent readers (Infinite when -f) (default: 3)
--recursive, -R: Recursively walk a non-globbing path and search for plain-files
