Now archived and moved onto a rust implementation of this tool called: snazy
sugarjazy - parse json logs nicely
sugarjazy is a simple tool to parse json logs and output them in a nice format with nice colors.
Usually play nicely with https://github.com/uber-go/zap when using the "Sugar" logger output.
As a tekton developer this works pretty well with tekton controllers and webhooks pods but
the shoudld work as well with most knative package and other pods using go-uber/zap.

Installation
There is not many dependencies on this package but python-dateutil is an optional dependency, if the package is not installed you will not be be able to show the log timestamps.
Arch
You can install it from aur with your aurhelper, like yay :
yay -S sugarjazy
pip
With pip from pypi - https://pypi.org/project/sugarjazy/
pip install --user sugarjazy
(make sure $HOME/.local/bin is in your PATH)
Docker
docker run ghcr.io/chmouel/sugarjazy:main
git clone
you will need poetry :
git clone https://github.com/chmouel/sugarjazy
cd sugarjazy
poetry run sugarjazy
Usage
You can use sugarjazy in multiple ways :
- By piping your logs:
kubectl logs podname|sugarjazy - By streamining your logs:
kubectl logs -f podname|sugarjazy -f - Directly to a file (or multiples files):
sugarjazy /tmp/file1.log /tmp/file2.log - Using kail from https://github.com/boz/kail piping the output to
sugarjazywith the--kailflag. The advantage ofkailis to be able to get the logs from multiple pods and watching new events as they appears.-
By default the prefix of the pod/container will be printed unless you specify the option
--kail-no-prefix. -
The prefix can be customized with
--kail-prefix-formatflag, the default template is :{namespace}/{pod}[{container}]If you want to see only the pod name you can simply do :`--kail-prefix-format="[{pod}]"` -
The
--kailflags always assume--followimplicitely.

Options
usage: sugarjazy [-h] [--timeformat TIMEFORMAT]
[--regexp-highlight REGEXP_HIGHLIGHT]
[--disable-event-colouring] [--filter-level FILTER_LEVEL]
[--stream] [--kail] [--kail-no-prefix]
[--kail-prefix-format KAIL_PREFIX_FORMAT]
[--regexp-color REGEXP_COLOR] [--hide-timestamp]
[files ...]
positional arguments:
files
options:
-h, --help show this help message and exit
--timeformat TIMEFORMAT
timeformat default only to the hour:minute:second. Use
"%Y-%m-%d %H:%M:%S" if you want to add the year
--regexp-highlight REGEXP_HIGHLIGHT, -r REGEXP_HIGHLIGHT
Highlight a regexp in message, eg: "Failed:\s*\d+,
Cancelled\s*\d+"
--disable-event-colouring
By default sugarjazy will try to add a ˃ char with a
color to the eventid to easily identify which event
belongs to which. Use this option to disable it.
--filter-level FILTER_LEVEL, -F FILTER_LEVEL
filter levels separated by commas, eg: info,debug
--stream, -s, -f, --follow
wait for input stream
--kail, -k assume streaming logs from kail
(https://github.com/boz/kail)
--kail-no-prefix by default kail will print the prefix unless you
specify this flag
--kail-prefix-format KAIL_PREFIX_FORMAT
the template of the kail prefix.
--regexp-color REGEXP_COLOR
Regexp highlight color
--hide-timestamp, -H don't show timestamp
NOTE
- Sugarjazy tries hard to identify the same event and add all events on the same colors to the chevron character (˃).
- The json fields are not standardize. It works well with
knativebased controllers liketektonor others but that may be buggy for other ones.
FAQ
- sugarjazy is along word to type and why did the name anyway?
- : I agree! and that's why I alias it with
alias sj=sugarjazyor even better I have zsh global aliasalias -g SJ=| sugarjazy -sto avoid even more typing.
- : I agree! and that's why I alias it with
