RRD RPi4 monitoring scripts

This is a set of monitoring tools, tailored for a Raspberry Pi 4 running Ethereum staking software. These are purely Linux scripts, designed to be as lightweight as possible, as a RPi4 staking Ethereum is typically running close to its limits.

1. Prerequisites:

• rrdtool: sudo apt-get install rrdtool

• hdsentinel-armv8: https://www.hdsentinel.com/hard_disk_sentinel_linux.php

2. Create databases:

rrdtool create disk.rrd --start now --step 3600 --no-overwrite DS:disk_full:GAUGE:7200:U:U DS:disk_health:GAUGE:7200:U:U RRA:AVERAGE:0.5:1:8760 RRA:AVERAGE:0.5:24:3650

rrdtool create sysmon.rrd --start now --step 60 --no-overwrite DS:load1:GAUGE:120:U:U DS:load5:GAUGE:120:U:U DS:load15:GAUGE:120:U:U DS:cpu_temp:GAUGE:120:U:U DS:usedmem:GAUGE:120:U:U DS:freemem:GAUGE:120:U:U DS:buffmem:GAUGE:120:U:U DS:availmem:GAUGE:120:U:U DS:usedsw:GAUGE:120:U:U DS:freesw:GAUGE:120:U:U RRA:AVERAGE:0.5:1:44640 RRA:AVERAGE:0.5:60:43800

rrdtool create disktemp.rrd --start now --step 3600 --no-overwrite DS:disk_temp:GAUGE:7200:U:U RRA:AVERAGE:0.5:1:8760 RRA:AVERAGE:0.5:24:3650

3. Setup cron jobs as root:

sudo crontab -e

* * * * * /home/user/path-to-script/collect_1m.sh
2 * * * * /home/user/path-to-script/collect_1h.sh
