Where and How to declare the ---storage.tsdb.retention.time=90d flag

[Anirudh Pasalapudi]

Hello,


I deployed prometheus using automation and I used a shell file to run the configuration file of prometheus. The contents of the file are mentioned below. However currently the default storage retention period is 15d. I want this to be changed to 90d. I tried to declare the flag --storage.tsdb.retention.time=90d in the prometheus.yml file and also in the below mentioned bash file. When I do that application is not coming up. If I have to add that flag in the below file, where exactly I need to declare that flag and how can I do that. Can anyone please help.

#!/bin/bash

prometheus_binary=/apps/prometheus/prometheus-2.19.0.linux-amd64/prometheus

prometheus_pid=/var/run/prometheus.pid

prometheus_flags=--config.file=/apps/prometheus/prometheus-2.19.0.linux-amd64/prometheus.yml

case "$1" in

    start)

        if [ -f "$prometheus_binary" ]; then

            $prometheus_binary $prometheus_flags> /dev/null 2>&1 &

            echo $! >$prometheus_pid;

            echo $prometheus_flags

        fi

        ;;

    stop)

        PID=$(cat $prometheus_pid);

        kill -9 $PID;

        rm -rf $prometheus_pid

        ;;

    restart)

  if [ -f $prometheus_pid ]; then

    PID=$(cat $prometheus_pid);

          kill -9 $PID;

          $prometheus_binary $prometheus_flags > /dev/null 2>&1 &

          echo $! >$prometheus_pid

  else

    $prometheus_binary -i $prometheus_flags > /dev/null 2>&1 &

                echo $! >$prometheus_pid

  fi

        exit 0

  ;;

    *)

        echo "Usage: $0 {start|stop|restart}"

  exit 1

esac

exit 0

With the other flags:

prometheus_flags="--config.file=/apps/prometheus/prometheus-2.19.0.linux-amd64/prometheus.yml --storage.tsdb.retention.time=90d"
