no logs for scripts.

the script code:

#!/bin/bash

WEBHOOK_URL='https://qyapi.weixin.qq.com/cgi-bin/webhook/send'

CONTENT="earlyoom killed\n\n"
CONTENT+="PID: $EARLYOOM_PID\n"
CONTENT+="NAME: $EARLYOOM_NAME\n"
CONTENT+="CMD: $EARLYOOM_CMDLINE\n"
CONTENT+="UID: $EARLYOOM_UID"

curl -X POST "$WEBHOOK_URL" \
     -H "Content-Type: application/json" \
     -d "{
           \"msgtype\": \"text\",
           \"text\": {
               \"content\": \"$CONTENT\"
           }
     }"

config:

EARLYOOM_ARGS="-r 600 -m 10 -s 10 -N /etc/notifer/script.sh --avoid '(^|/)(init|sshd)$'"

May I ask if this is correct for me? How to check if a script runs when a process is killed, how to view script run logs or check error messages?Thanks!

I had a similar problem, except for the desktop notifications. Since I couldn't get -N to work, I created this script, /home/user/.local/bin/syslog-check.sh:

#!/bin/bash
REGEX_PATTERN="$1"
SINCE_TIME="$(date --date='15 seconds ago' '+%Y-%m-%d %H:%M:%S')"
export DISPLAY=:0
journalctl --since="$SINCE_TIME" --quiet | grep -v $0 | grep --line-buffered -E "$REGEX_PATTERN" | while read -r line; do
    notify-send "journal" "$line"
done

Then I run it using crontab

$ crontab -e
# check for earlyoom syslog messages and send desktop notification every 15 seconds
* * * * * /home/user/.local/bin/syslog-check.sh "earlyoom.*SIG" 15 >/dev/null 2>&1
* * * * * (sleep 15; /home/user/.local/bin/syslog-check.sh "earlyoom.*SIG" 15) >/dev/null 2>&1
* * * * * (sleep 30; /home/user/.local/bin/syslog-check.sh "earlyoom.*SIG" 15) >/dev/null 2>&1
* * * * * (sleep 45; /home/user/.local/bin/syslog-check.sh "earlyoom.*SIG" 15) >/dev/null 2>&1

Yea, just tried this on v1.8.2 and even with debug, there is no mention of it ever trying to execute my script.

The script definitely works when run by itself.

Anything in the startup messages? Examples:

$ ./earlyoom -N foobar.sh
earlyoom v1.8.2-5-gd38e29b
mem total: 23885 MiB, user mem total: 22366 MiB, swap total:    0 MiB
sending SIGTERM when mem avail <= 10.00% and swap free <= 10.00%,
        SIGKILL when mem avail <=  5.00% and swap free <=  5.00%
startup_selftests: -N: notify script 'foobar.sh' is not an absolute path, disabling -N

Or here:

$ ./earlyoom -N $PWD/foobar.sh
earlyoom v1.8.2-5-gd38e29b
mem total: 23885 MiB, user mem total: 22357 MiB, swap total:    0 MiB
sending SIGTERM when mem avail <= 10.00% and swap free <= 10.00%,
        SIGKILL when mem avail <=  5.00% and swap free <=  5.00%
startup_selftests: -N: notify script '/home/jakob/code/earlyoom/foobar.sh' is not executable: No such file or directory

...and I added a debug message now when the -N script is executed. There really should have been one.
