Simple and Reliable CPU/MEM Usage Monitoring Tool — V2.0

License and Purchase

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

Step 1 - Generate probe.txt

cpualert -probe > probe.txt

This command generates the machine information required for license creation.

Step 2 - Purchase License

To purchase or renew your license, please visit:
https://www.smartbooth.com/purchase_lic.htm

Step 3 - Send probe.txt

Email your generated probe.txt to:

A matching license.dat will then be prepared for your machine.

Step 4 - Verify License

cpualert -licenseinfo

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

Files Included

Quick Start

1. Unzip and copy all files into one folder.
2. Make sure curl is available on this system.
3. Edit cpualert_setup.txt to define thresholds and intervals.
4. Edit cpualert_notify.txt to define your SMTP, Microsoft Teams webhook, and Telegram settings.
5. Run cpualert -check first to validate config format, then run cpualert -test to confirm Email, Microsoft Teams, Telegram, and Smartbooth SMS delivery before enabling background mode.
6. Place your valid license.dat in the same folder.
7. Open Command Prompt in this folder and run cpualert.

curl --version
cpualert
cpualert -check
cpualert -test

3. Copy the generated webhook URL.
4. Paste it into teams_webhook in cpualert_notify.txt.
5. Run cpualert -check to validate the file format.
6. Run cpualert -test to verify Email, Microsoft Teams, Telegram, and Smartbooth SMS delivery.

Parameter Description

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.

Command Reference

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.
• Use a stable SMTP account.
• Test with lower thresholds first to verify Email, Microsoft Teams, Telegram, and Smartbooth SMS alerts are working correctly.

Troubleshooting

No Email Alert

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

No Microsoft Teams Alert

• Check teams_webhook in cpualert_notify.txt.
• Make sure the webhook URL is complete, on one line, and enclosed in double quotes.
• Confirm the Power Automate flow run history shows success.
• Confirm built-in curl is available by running curl --version.
• Run cpualert -test and check console output for Teams command rc=0.

Alert Sent Too Early

• Check cpuhighnum, memhighnum, cpulownum, and memlownum.
• These values mean consecutive 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 or terminal.
• If curl is not available, use a Windows/Linux version that includes built-in curl.
