Usage

Scheduling

Using schedule module for job scheduling, you can found the scheduling setting at configuration file.

Alternative solution is using Linux built-in Cron function.

Configuration

Store configuration as JSON format file, named config.json.

You can editing the clean copy, which looks like this:

{
  "schedule_config": 10,
  "path_and_filename": "apcupsd_voltage_record.csv",
  "row_date": 1,
  "row_voltage": 11,
  "prefix_date":"DATE     :",
  "prefix_voltage":"LINEV    :"
}

• schedule_config setting the execution period.
• path_and_filename setting the voltage recording filename and storage path.
• row_date reference to row number of datetime.
• row_voltage reference to row number of voltage report.
• prefix_date delete the prefix at datetime row.
• prefix_voltage delete the prefix at voltage row.

Web monitor address

This function need monitor's web address, can be LAN address.

import voltage_recorder

# Web monitor address
upsfstats = "http://192.168.0.1/upsfstats.cgi?host=127.0.0.1"
# Get result
result = voltage_recorder.apcupsd_upsfstats(upsfstats)

Cron mode

Startup script by Linux built-in Cron function by crontab configuration.

• Get voltage data from apcaccess

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
*/10 *  *  *  * pi python /python_script/crontab_apcaccess.py

• Get voltage data from apcupsd-cgi program

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# Example of job definition:
# .---------------- minute (0 - 59)

Schedule mode

• Get voltage data from apcaccess

user@localhost:~/python_script python schedule_apcaccess.py

• Get voltage data from apcupsd-cgi program

user@localhost:~/python_script python schedule_upsfstats.py

After startup, it will print this:

Scheduled period is 10 minutes.
Pressing CTRL+C to exit voltage monitor.

If you want to terminate the Program, pressing CTRL+C, it will print this:

^C
Thank you for using the voltage monitor.
GoodBye ...
