Multi-threading to Ping up to 50 hosts in parallel

Simple and reliable host monitoring tool for Windows and Linux.
Check multiple hosts in parallel using worker threads.
Useful when a small or medium business needs to monitor large volumes of devices, routers, servers, or branch endpoints.
Low Noise Alert Logic - Send alerts only when get consecutive PING loss, and send recovery notification when the host restored.

✔ Multi-threading Design for Faster Host Checking PingAlert can check multiple hosts in parallel using worker threads instead of checking one by one. This is especially useful for small and medium businesses monitoring many routers, servers, office devices, and branch endpoints.

No installation. No server. No complexity.
Just run and monitor your systems in 1 minute.

Multi-threaded Workers for Faster Host Monitoring

PingAlert supports worker threads to check multiple hosts in parallel. The program still runs as one simple background process, but inside that process it can run multiple checks at the same time. This makes PingAlert more useful for small and medium businesses that monitor many devices, routers, servers, VPN endpoints, and branch office targets.

Parallel Host Checking

  • Check multiple hosts at the same time
  • Reduce total scan time for many devices
  • Good for routers, servers, and office devices
  • Useful for branch endpoint monitoring

Simple Configuration

workers : "2"
  • Default workers: 2
  • Maximum safe limit: 50
  • Trial mode target limit remains 2 hosts
  • Licensed mode can monitor more targets

One Process Design

Do not start multiple copies of PingAlert. Use one background process and configure workers instead.

  • Avoid duplicate alerts
  • Avoid duplicate Teams, Email, or Telegram messages
  • Keep PID and status handling simple
  • Use pingalert -start only once

Why PingAlert

Best for servers, routers, firewalls, VPN endpoints, office network devices, branch endpoints, and remote systems.

  • Lightweight and fast

Workers Configuration Example

Add workers to pingalert_host.txt. If workers is not set, PingAlert uses the default value 2. 

interval : "15"
fast_retry_interval : "5"
pingcount : "3"
workers : "2"

host : "192.168.3.3"
description : "Office Router"
timeoutsec : "5"
alertcount : "3"
pinglossmsg : "default"
pingbackmsg : "default"
tcpfallback : "yes"

host : "192.168.3.4"
description : "Branch Firewall"
timeoutsec : "5"
alertcount : "3"
pinglossmsg : "default"
pingbackmsg : "default"
tcpfallback : "yes"
Recommended setting: start with workers : "2". Increase only when you monitor many hosts and need faster scan completion. Maximum safe limit is workers : "50".

Example Alert

[192.168.3.3] Ping Timeout... 192.168.3.3 received=0/4 count 3/3

Sending email alert ...
Email command rc=0

Sending Microsoft Teams alert ...
Teams command rc=0

Sending Telegram alert ...
Telegram command rc=0
PingAlert is designed to avoid repeated alert flooding while a host remains unreachable. It sends a new alert again when the host recovers or changes state.
