Bitbass Posted January 4, 2020 Share Posted January 4, 2020 I've been running a simple script in the custom directory to export Unraid stats to an Influx DB for Grafana. Upgrading to 6.8 and I knew it would break. I wanted to find a better way of running the same script and it turned out to be pretty simple. In Settings and User Scripts, add a new script and include the following: #!/bin/bash # # Set Vars # DBURL=http://x.x.x.x:8086 DBNAME=dashboard DEVICE="UNRAID" CURDATE=`date +%s` # Current array assignment. # I could pull the automatically from /var/local/emhttp/disks.ini # Parsing it wouldnt be that easy though. DISK_ARRAY=( sdf sde sdj sdq sdn sdg sdh sdp sdl sdm sdd sdb sdc sdi sdk sdo nvme0n1 ) DESCRIPTION=( parity disk1 disk2 disk3 disk4 disk5 disk6 disk7 disk8 disk9 disk10 disk11 disk12 disk13 disk14 disk15 cache ) # # Added -n standby to the check so smartctl is not spinning up my drives # i=0 for DISK in "${DISK_ARRAY[@]}" do smartctl -n standby -A /dev/$DISK | grep "Temperature_Celsius" | awk '{print $10}' | while read TEMP do curl -is -XPOST "$DBURL/write?db=$DBNAME" --data-binary "DiskTempStats,DEVICE=${DEVICE},DISK=${DESCRIPTION[$i]} Temperature=${TEMP} ${CURDATE}000000000" >/dev/null 2>&1 done ((i++)) done # Had to increase to 10 samples because I was getting a spike each time I read it. This seems to smooth it out more top -b -n 10 -d.2 | grep "Cpu" | tail -n 1 | awk '{print $2,$4,$6,$8,$10,$12,$14,$16}' | while read CPUusr CPUsys CPUnic CPUidle CPUio CPUirq CPUsirq CPUst do top -bn1 | head -3 | sed -e 's/.*load//g' | awk '/average/ {print $2" "$3" "$4}' | sed -e 's/,//g' | while read LAVG1 LAVG5 LAVG15 do curl -is -XPOST "$DBURL/write?db=$DBNAME" --data-binary "cpuStats,Device=${DEVICE} CPUusr=${CPUusr},CPUsys=${CPUsys},CPUnic=${CPUnic},CPUidle=${CPUidle},CPUio=${CPUio},CPUirq=${CPUirq},CPUsirq=${CPUsirq},CPUst=${CPUst},CPULoadAvg1m=${LAVG1},CPULoadAvg5m=${LAVG5},CPULoadAvg15m=${LAVG15} ${CURDATE}000000000" >/dev/null 2>&1 done done if [[ -f byteCount.tmp ]] ; then # Read the last values from the tmpfile - Line "eth0" grep "eth0" byteCount.tmp | while read dev lastBytesIn lastBytesOut do cat /proc/net/dev | grep "eth0" | grep -v "veth" | awk '{print $2, $10}' | while read currentBytesIn currentBytesOut do # Write out the current stats to the temp file for the next read echo "eth0" ${currentBytesIn} ${currentBytesOut} > byteCount.tmp totalBytesIn=`expr ${currentBytesIn} - ${lastBytesIn}` totalBytesOut=`expr ${currentBytesOut} - ${lastBytesOut}` curl -is -XPOST "$DBURL/write?db=$DBNAME" --data-binary "interfaceStats,Interface=eth0,Device=${DEVICE} bytesIn=${totalBytesIn},bytesOut=${totalBytesOut} ${CURDATE}000000000" >/dev/null 2>&1 done done else # Write out blank file echo "eth0 0 0" > byteCount.tmp fi # Gets the stats for boot, disk#, cache, user # df | grep "mnt/\|/boot\|docker" | grep -v "user0\|containers" | sed 's/\/mnt\///g' | sed 's/%//g' | sed 's/\/var\/lib\///g'| sed 's/\///g' | while read MOUNT TOTAL USED FREE UTILIZATION DISK do if [ "${DISK}" = "user" ]; then DISK="array_total" fi curl -is -XPOST "$DBURL/write?db=$DBNAME" --data-binary "drive_spaceStats,Device=${DEVICE},Drive=${DISK} Free=${FREE},Used=${USED},Utilization=${UTILIZATION} ${CURDATE}000000000" >/dev/null 2>&1 done Make sure to adjust the top couple of variables. You can then set the timer to whatever you like. I'm tracking CPU and network so I like to do it every two minutes. Set the schedule for the script to Custom and use */2 * * * * for the timer (cron). Make sure to remove any added carriage returns when you copy and paste the script. I'm running Influx and Grafana on a separate system. I believe there are integrated ways to do this if you're running in a docker on Unraid. Quote Link to comment
