# Stats tools
These tools are suitable for parsing librdkafka's statistics
as emitted by the `stats_cb` when `statistics.interval.ms` is set.
* [to_csv.py](to_csv.py) - selectively convert stats JSON to CSV.
* [graph.py](graph.py) - graph CSV files.
* [filter.jq](filter.jq) - basic `jq` filter.
Install dependencies:
$ python3 -m pip install -r requirements.txt
Examples:
# Extract stats json from log line (test*.csv files are created)
$ grep -F STATS: file.log | sed -e 's/^.*STATS: //' | ./to_csv.py test1
# Graph toppar graphs (group by partition), but skip some columns.
$ ./graph.py --skip '*bytes,*msg_cnt,stateage,*msgs,leader' --group-by 1partition test1_toppars.csv
