SupervisordStat

Run pidstat over supervisord processes.

Usage

The process will log to a file named monit-{process-name}.txt. Use the following configuration in supervisord to start monitoring:

[eventlistener:mylistener]
command=./supervisordstat
events=PROCESS_STATE
autorestart=true
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes = 0
redirect_stderr=true

To transform the output to csv and json, one may use csvtk:

#!/bin/bash

# Usage to-csv.sh monit-logger.txt

temp=${1/txt/temp}
tab=${1/txt/tab}
csv=${1/txt/csv}
json=${1/txt/json}
head -n 3 $1 | tail -n 1 | sed 's/# //' > $temp
sed '1d' $1 >> $temp
csvtk space2tab $temp > $tab
csvtk tab2csv $tab > $csv
csvtk csv2json $csv > $json
rm $temp $tab
