Raspberry Pi Monitor

Use RRDTool monitor Raspberry Pi, include CPU temperture, Memory usage, Disk I/O, Network I/O…


install packages

$sudo apt-get install libcairo2-dev libpango1.0-dev libglib2.0-dev libxml2-dev \ 
 librrd-dev python2.7-dev rrdtool python-rrdtool
$wget https://pypi.python.org/packages/source/p/psutil/psutil-2.1.1.tar.gz
$tar xf psutil-2.1.1.tar.gz
$cd psutil-2.1.1
$sudo python setup.py install

Download or clone rpi-monitor on github

Setup Crontab

By defualt, the cron.log is disabled in Raspbian. To enable it:

sudo vi /etc/rsyslog.conf

find the line and uncomment it.

# cron.*                          /var/log/cron.log

Restart rsyslog via:

sudo /etc/init.d/rsyslog restart

Modify crontab

crontab -e

Add schedule as below

#data collection every 5 minutes
*/5 * * * * /path/to/rpi-monitor/rpi_monitor.py
#generate daily graph report at 00:01
1 0 * * * /path/to/rpi-monitor/graphReport.py -1d
#generate weekly graph report at 00:03 on Monday
3 0 * * 1 /path/to/rpi-monitor/graphReport.py -1w
