Remote monitoring and management in Raspberry Pi - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to install the monitoring agent on Raspberry Pi using apt.

Raspberry Pi

sudo apt-get update && sudo apt-get install [1]

💡 Hint

Common Mistakes

Installing unrelated packages like nginx or vim instead of a monitoring tool.

The htop package is a popular monitoring tool for system resources on Raspberry Pi.

Complete the command to check the Raspberry Pi's CPU temperature.

Raspberry Pi

cat [1]

Drag options to blanks, or click blank then click option'

A/proc/meminfo

B/etc/hostname

C/var/log/syslog

D/sys/class/thermal/thermal_zone0/temp

Attempts:

💡 Hint

Common Mistakes

Using files unrelated to temperature like /proc/meminfo or /etc/hostname.

The CPU temperature can be read from the file /sys/class/thermal/thermal_zone0/temp on Raspberry Pi.

Fix the error in the command to start the monitoring service named 'monit'.

Raspberry Pi

sudo systemctl [1] monit

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Typo in 'restartt' instead of 'restart'.

Using 'stop' instead of 'start'.

The correct command to start a service is sudo systemctl start monit. The option restartt is a typo.

4fill in blank

hard

Fill both blanks to create a command that shows the last 10 lines of the system log and follows new entries.

Raspberry Pi

sudo tail [1] 10 [2] /var/log/syslog

Drag options to blanks, or click blank then click option'

A-n

B-f

C-r

D-q

Attempts:

💡 Hint

Common Mistakes

Using -r which reverses output order.

Using -q which suppresses headers.

The -n option specifies the number of lines to show, and -f follows new log entries in real-time.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps sensor names to their readings if the reading is above 50.

Raspberry Pi

sensor_data = [1]: [2] for [3] in sensors if [2] > 50 }

Drag options to blanks, or click blank then click option'

Aname

Bvalue

Cname, value

Dsensor

💡 Hint

Common Mistakes

Using 'name, value' as a single variable.

Using the same variable for key and loop variable.

The comprehension maps name to value for each sensor in sensors where the value is greater than 50.
