Unable to set-up with raid devices

[giovi321]

Hi,
it seems that my raid 0 devices are not liked by the python program.
Here's my psmqtt.conf:

import socket

mqtt_broker = '192.168.1.65'       # default: 'localhost'
mqtt_port = 1883                # default: 1883
mqtt_clientid = 'GC01SRVR'
mqtt_username = 'mqtt'
mqtt_password = 'mqtt_password'
mqtt_clean_session = False
mqtt_qos = 0
mqtt_retain = False
#mqtt_topic_prefix = 'psmqtt/'
mqtt_topic_prefix = 'psmqtt/' + socket.gethostname() + '/'
mqtt_request_topic = 'request'




schedule = {
    "every 1 minute" :    [
        "cpu_percent",
        "virtual_memory/percent",
     ],
    "every 60 minutes"  :     "disk_usage/percent/|",  # slash replaced with vertical slash
    "every 1 second" : [
        "disk_usage/percent/|dev|mapper|backup",
        "disk_usage/percent/|dev|mappervm",
        "disk_usage/percent/|dev|mapper3tb",
        "disk_usage/percent/|dev|mapper|4tb",
        "disk_usage/percent/|",
    ]
}

Forgot to add the error I get:

root@GC01SRVR:psmqtt$ python3 psmqtt.py

    if task.startswith(topic_prefix):

Could you help me out a bit please? :)

I figured out with a bash script if anybody is interested:

Prerequisites:
apt-get install mosquitto-clients
For the disks:

#!/bin/sh
df -hl | grep '/dev/md127' | awk '{;percent+=$5;} END{print percent}' | column -t > /home/programmi/mqtt/root.txt
df -hl | grep '/dev/mapper/4tb' | awk '{;percent+=$5;} END{print percent}' | column -t > /home/programmi/mqtt/4tb.txt
df -hl | grep '/dev/mapper/3tb' | awk '{;percent+=$5;} END{print percent}' | column -t > /home/programmi/mqtt/3tb.txt
df -hl | grep '/dev/mapper/backup' | awk '{;percent+=$5;} END{print percent}' | column -t > /home/programmi/mqtt/backup.txt
df -hl | grep '/dev/mapper/vm' | awk '{;percent+=$5;} END{print percent}' | column -t > /home/programmi/mqtt/vm.txt

mosquitto_pub -h 192.168.1.65 -p 1883 -u user -P mqtt_password -t GC01SRVR/disk_usage/root -f /home/programmi/mqtt/root.txt
mosquitto_pub -h 192.168.1.65 -p 1883 -u user -P mqtt_password -t GC01SRVR/disk_usage/4tb -f /home/programmi/mqtt/4tb.txt
mosquitto_pub -h 192.168.1.65 -p 1883 -u user -P password -t GC01SRVR/disk_usage/3tb -f /home/programmi/mqtt/3tb.txt
mosquitto_pub -h 192.168.1.65 -p 1883 -u user -P password -t GC01SRVR/disk_usage/backup -f /home/programmi/mqtt/backup.txt
mosquitto_pub -h 192.168.1.65 -p 1883 -u user -P password -t GC01SRVR/disk_usage/vm -f /home/programmi/mqtt/vm.txt

For the CPU:

#!/bin/bash
awk '{u=$2+$4; t=$2+$4+$5; if (NR==1){u1=u; t1=t;} else print ($2+$4-u1) * 100 / (t-t1) ; }' <(grep 'cpu ' /proc/stat) <(sleep 1;grep 'cpu ' /proc/stat) > /home/prog>

mosquitto_pub -h 192.168.1.65 -p 1883 -u user -P password -t GC01SRVR/cpu_usage -f /home/programmi/mqtt/cpu.txt

For the memory available:

#!/bin/bash
AVAILABLEMEM=$(grep MemAvailable /proc/meminfo | grep -o -E '[0-9]+')
echo "scale=2;$AVAILABLEMEM/1000000" | bc > /home/programmi/mqtt/memoryavailable.txt
mosquitto_pub -h 192.168.1.65 -p 1883 -u user -P password -t GC01SRVR/memory_available -f /home/programmi/mqtt/memoryavailable.txt

For the uptime

#!/bin/bash
UPTIME=$(cat /proc/uptime | head -n1 | awk '{print $1;}')
echo "scale=2;$UPTIME/60/60/24" | bc > /home/programmi/mqtt/uptime.txt
mosquitto_pub -h 192.168.1.65 -p 1883 -u user -P password -t GC01SRVR/uptime -f /home/programmi/mqtt/uptime.txt
