Simple and powerful CPU, memory, and system-health monitoring for Windows and Linux.
No installation required. Offline license. Permanent or annual site licensing.
cpualert -check. Resolve configuration errors before continuing.cpualert without switches to monitor in the foreground. Watch the live screen output and confirm the targets or thresholds, monitoring results and any errors. If another instance is already running, stop it first. Foreground monitoring can send real alerts to configured recipients.cpualert -start for long-running background monitoring, cpualert -status to check its status, and cpualert -stop when you want to stop it. Review the product log during unattended operation.cpualert -check cpualert
Observe the live output, then press Ctrl+C. After the foreground process exits:
cpualert -start cpualert -status
Leave the background monitor running for as long as needed. To stop it later:
cpualert -stop
Use the application directory as the working directory for every command. Background mode does not itself configure automatic startup after a reboot.
On Windows use cpualert.exe; on Linux use ./cpualert. Follow the same sequence on each platform.
CPUAlert can send important CPU and memory notifications directly to a Microsoft Teams channel. This helps your team see server health issues in the same place where daily operation communication already happens.
Configure your Email, Microsoft Teams and Telegram settings in the configuration file.

If you want full setup examples, Microsoft Teams webhook configuration, configuration file format, commands, and troubleshooting, open the documentation page below.
Use the new cpualert_notify.txt configuration for SMTP, Teams, Telegram and optional Smartbooth SMS. Migrate your previous notification settings to this file. Email messages preserve line breaks so the time, host, failure details and process rows remain readable.
This optional service sends SMS and email alerts from Smartbooth.com and works independently of your own SMTP settings. Register for a Smartbooth SMS account for free testing. Put your own account settings in the product's _notify.txt file. Multiple phone numbers and email addresses are comma-separated.
sms_url : "https://www.smartbooth.com/smartalert/alert.php" sms_account : "[email protected]" sms_password : "your-password" sms_phone : "+10000000001,+10000000002" sms_email : "[email protected]"
Prefix unused settings with *. The downloadable templates disable notification channels until configured. Run -check first. -test sends real messages to configured recipients.
Trial notifications display [Trial Mode]. Email, Teams and Telegram trial alerts are limited to two per channel per day; IamAlive is limited to one per day. PingAlert and PortAlert trial monitoring is limited to two targets. Windows SMS trial allows two successful deliveries per day. Linux SMS trial allows two attempts, persisted in .alert_sms_trial_state. A valid license removes trial restrictions; application capacity and SMS service charges still apply.
V2.0 adds disk free-space checks, required process/service checks, failure details and Health OK recovery messages alongside CPU/memory thresholds and top-five process reports. Windows GPU health checks display-adapter device status; Linux optionally checks NVIDIA temperature and query failures using nvidia-smi. These checks do not replace the separate GPUAlert product.
health_enabled : "yes" health_disk : "C:\" health_disk_min_free : "10" health_fail_num : "3" *health_services : "Spooler,W32Time" *health_processes : "myserver.exe" *health_gpu : "yes"
health_enabled : "1" health_disk : "/" health_min_free : "10" health_count : "3" health_temperature : "90" health_gpu : "0" *health_process : "nginx" *health_service : "nginx.service"
Windows accepts comma-separated service/executable names. Linux checks one exact process name and one systemd service; enable health_gpu only where NVIDIA nvidia-smi is available. Consecutive failure counts suppress transient failures. Linux ./cpualert -healthcheck prints a read-only health report (exit 0 healthy, 1 failure).
Permanent licenses: Single Tool $49; Any 2 Licenses $89; Complete Bundle $119. A single license covers one product on one host and one operating system. CPUAlert for Windows and CPUAlert for Linux count as two licenses, even on the same physical machine. The Complete Bundle covers CPUAlert, PingAlert and PortAlert on the same host and OS. Permanent licenses include the purchased version forever, plus one year of updates and general email support; later updates/support are optional and quoted separately.
Annual Site plans include all three tools: Small $299/year for up to 10 host/OS installations; Standard $999/year for up to 50; Large $2,499/year for up to 200. Windows and Linux installations can be mixed; each host/OS installation counts separately, including virtual machines. Deployments may be reassigned within the site allowance during the term. Annual plans use one payment for one year and manual renewal, with no automatic recurring charge. Remote IP addresses and ports monitored by PingAlert/PortAlert do not count as installations; application capacity limits still apply. GPUAlert is sold separately. SMS credits and delivery charges are separate.
