editMessage example - Githubissues

jonashaag commented 3 years ago

I use editMessage to maintain a "self-updating" message with server stats. I added this:

The script I use (see below for the definition of $msg):

MSGID=24
source bashbot.sh
edit_markdownv2_message "$(getConfigKey "botadmin")" $MSGID "$msg"

You have to get the message id (24 in my example) from somewhere. Not sure where you're supposed to get it from; I got it from MESSAGE.log with debug mode.

Just posting this here in case someone finds it useful.

Code for $msg:

gpu=`nvidia-smi --query-gpu=utilization.gpu --format=csv,noheader,nounits`
cpu=`uptime | egrep -o 'load.+' | cut -d ' ' -f 3- | sed s/,[0-9]/.\0/g`
mem=`free -h | grep Mem | sd '\s+' ' ' | cut -d ' ' -f3`
df=`df -h /mnt /mnt2 / | tail -n+2`

msg=$(cat <<EOF
\`\`\`
GPU: $gpu%
CPU: $cpu
Mem: $mem
