CPUAlert Personal

CPUAlert Personal watches system CPU and RAM usage, sends Email and Telegram alerts after consecutive High / Low usage checks, and sends recovery messages when usage returns to normal. Simple setup with offline license. No installation required. Edit configuration files and run it in ONE minute.

Overview

Offline License CPU Monitor Memory Monitor Email Alert Telegram Alert IamAlive

CPUAlert Personal is designed for simple server and workstation monitoring where sustained high/low CPU or memory usage needs fast notification.

Recommended for Windows/Linux servers, SQL servers, web servers, remote desktops, branch office PCs, and always-on systems that need simple resource monitoring.

Quick Start

Unzip and copy all files into one folder.
Make sure curl is available on this system.
Edit cpualert_setup.txt to define thresholds and intervals.
Edit cpualert_email.txt to define your SMTP and Telegram settings.
Run cpualert -check first to validate config format, then run cpualert -test to confirm Email and Telegram delivery before enabling background mode.

Open Command Prompt in this folder and run cpualert.

curl --version
cpualert
cpualert -check
cpualert -test
cpualert -start
cpualert -status
cpualert -stop
cpualert -licenseinfo
cpualert -probe

Email and Telegram Configuration

Edit cpualert_email.txt.

server : "smtp://smtp.gmail.com:587"
email : "your@gmail.com"
password : "your_app_password"
from : "your@gmail.com"
to : "admin1@hotmail.com,admin2@yahoo.com"
iamalive : "admin1@hotmail.com"
token : "your telegram bot token"
chat_id : "-123456789(telegram group chat id)"

Parameter Description

Parameter	Description
`server`	SMTP server and port. Example: `smtp://smtp.gmail.com:587`
`email`	SMTP login account.
`password`	SMTP password or app password. The program can auto-convert it to encrypted format.
`from`	Sender email address.
`to`	Main alert recipients.
`iamalive`	Daily keep-alive recipient. Email to let you know program is up and running at midnight.
`token`	Telegram bot token. The program can auto-convert it to encrypted format.
`chat_id`	Telegram chat ID or group ID.

Gmail with App Password is recommended because it is easy to set up, fast, and reliable for sending alert emails.

License

CPUAlert Personal uses an offline local license file named license.dat.

cpualert -probe > probe.txt

Send the generated probe.txt to us. A matching license.dat will be issued for your machine.

cpualert -licenseinfo

This command displays current license mode, customer, expire date, and machine matching result.

Alert Behavior

CPU and MEMORY alerts are based on consecutive high/low checks, not a single spike.
Example: if cpuhighthreshold : "85" and cpuhighnum : "3", CPU usage must stay at or above 85% for 3 consecutive checks before an alert is sent.
Example: if memlowthreshold : "50" and memlownum : "30", MEMORY usage must stay at or below 50% for 30 consecutive checks before an alert is sent.
After a HIGH/LOW alert is sent, repeated HIGH/LOW alerts are not sent again and again while the condition stays high/low.
When the value goes back below threshold, a RECOVERY alert is sent.
Midnight IamAlive can be sent to confirm the program is still running.

Trial Mode Limits

Item	Trial Limit
Email alerts	2 per day
Telegram alerts	2 per day
IamAlive	1 per day

Licensed mode removes the above Trial limits.

Command Reference

Command	Description
`cpualert`	Run in foreground mode.
`cpualert -start`	Start in background mode.
`cpualert -stop`	Stop background process.
`cpualert -status`	Check whether the monitor is running.
`cpualert -check`	Validate config file format. Use this first to catch `=` and missing keys.
`cpualert -test`	Send a test Email and Telegram alert to verify configuration.
`cpualert -probe`	Print machine probe information.
`cpualert -licenseinfo`	Show current license status.
`cpualert -s`	Silent mode.
`cpualert -h` / `cpualert --help`	Show command help and usage summary.

Recommended command flow: edit config, run cpualert -check and cpualert -test, then use cpualert -start for background monitoring.

Recommended Deployment

Install in a fixed folder such as CPUAlert.
Keep cpualert, license.dat, and config files in the same folder.
CPUAlert Personal uses the built-in Windows curl command for Email and Telegram delivery.
Use a stable SMTP account.
Test with lower thresholds first to verify Email and Telegram alerts are working correctly.

Troubleshooting

No Email Alert

Check SMTP server, account, password, and firewall rules.
Confirm Windows built-in curl is available by running curl --version.
Review cpualert_log.txt.
Check console output for Email command rc=0 or non-zero return code.

No Telegram Alert

Check token and chat_id.
Ensure the bot has permission to message the target chat or group.
Confirm Windows built-in curl is available by running curl --version.
Check console output for Telegram command rc=0 or non-zero return code.

Alert Sent Too Early

Check cpuhighnum and memhighnum.
These values mean consecutive high checks, not total checks since startup.

Still in Trial Mode

Confirm license.dat is in the same folder as cpualert.
Run cpualert -licenseinfo to check the reason.

curl Not Found

This package does not include curl.
Run curl --version in Command Prompt.
If curl is not available, use a Windows/Linux version that includes built-in curl.
