python rpi UA Size

Simply Python automatically report module working on Raspberry Pi.

Contents

Usage

Scheduling

  • Schedule
    You can using schedule module for job scheduling, you can found the scheduling setting at scripts examples.
import schedule

#Execute setting
schedule.every(30).minutes.do( #Something Package as function)
#Loop
try:
    while True:
        schedule.run_pending()
        time.sleep(1)
#Crtl+C to exit
except KeyboardInterrupt:
  print("GoodBye ...")
  • Crontab
    Alternatively, automatically execute via cron.
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name command to be executed
17 *	* * *	root    cd / && run-parts --report /etc/cron.hourly
25 6	* * *	root	test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6	* * 7	root	test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6	1 * *	root	test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )

Email sending

  • Google account needed, sign in using App passwords.
  • Receiver is unlimited. First time running email sending, it will asking configuration.
Mail Configuration not found, please initialize.

Please enter the sender account: example@gmail.com
Please enter the sender password: •••••••••
Please enter the receiver address: receiver@gmail.com

You can also set disalbe_phone_book to True, directly setting email configuration.

#Email configuration Mode
disalbe_phone_book = False

#If set "disalbe_phone_book" True
sender_account = "example@gmail.com"
sender_password = "•••••••••"
receiver_address = "receiver@gmail.com"

Temperature alert

Critical value is necessary, can be integer or floating point. Configure store at config.json.

"tempture_alert": {
  "critical": 55.0
  },

The critical value, unit of temperature is degree celsius.

IP address change detection

If default address is empty, it will fill in when initialization.

"ip_address_alert": {
  "ipv4": "1.1.1.1",
  "ipv6": "2606:4700:4700::1111"
  },

Program or process checking

If default address is empty, it will print error message when initialization, or return True as result.

Query not found. Configuration is necessary.

Configure store at config.json.

"program_checker": {
  "program": ""
  },

Configuration file

Status4HaH store configuration as JSON format file, named config.json..
You can editing the clean copy, which looks like this:

{
    "mail": {
        "sender": "",
        "scepter": "",
        "receiver": ""
    },
    "tempture_alert": {
        "critical": 55.0
    },
    "ip_address_alert": {
        "ipv4": "",
        "ipv6": ""
    },
    "program_checker": {
        "program": ""
    },
    "last_update_time": ""
}

If you fill in with correct configure, it will skip initialization step.

Modules instantiation

If you want to using schedule module for job scheduling, install this module are needed.

Python module

  • Import the module
import automatically_report
import automatically_report as auto
  • Alternatively, you can import the function independent
from automatically_report import get_address

get_address(mode_select=False)

Function

Temperature report

import automatically_report

temperature = automatically_report.cputemperature(float_mode=True)

If you enable float_mode, it will return float. otherwise it will return integer.

Runnable script refer to coretemp_notice.py. After sending email it will print.

2021-02-26 11:11:11 | Temperature report complete.

Temperature high alert

Refer to coretemp_warning.py.

It will sending email if the CPU temperature higher then critical value.

2021-02-26 11:11:19 | Temperature report complete.

Otherwise it will print:

2021-02-26 11:11:31 | Core temperature under critical value.

IP address check

Refer to ip_address_notice.py.

Configure the mode_select to select IPv4 only or IPv6 only.

  • If you set mode_select to IPv4
    Compare IPv4 only.
  • If you set mode_select to IPv6
    Compare IPv6 only.

If address no change, it will print.

2021-02-26 11:28:56 | No changes detected.

If changes detected, depend on mode_select, it will sending email and print.

  • IPv4 only
2021-02-26 11:28:14 | 114.514.19.19
  • IPv6 only
2021-02-26 11:28:14 | 8930:8100:1145:141:919:36:114:514
  • If mode_select is default (False)
2021-02-26 11:28:14 | [True, False] | 1.1.1.1 | 8930:8100:1145:141:919:36:114:514

False means that IPv6 has been change.

Program Checker

Refer to program_checker.py. If the query program or process not found, it will sending email and print.

2021-02-26 11:12:55 | Program not found.
2021-02-26 11:12:55 | Status report complete.

Otherwise it will print:

2021-02-26 11:13:20 | Program found in process list.
