The WATCHDOG system is built on a Linux platform and provides comprehensive detection for maintenance and management through programs written in C by the Taiwanese team.
This chapter will take you through the detection items overview of the WATCHDOG system.
The detection functions of WATCHDOG can be broadly introduced in two categories:
1. WATCHDOG Local - Detection Items
Detection functions issued by WATCHDOG's local machine,
including website detection, packet testing (automatic Ping detection), and Socket Port checking.
The following details each function in detail,
helping you understand the various features of WATCHDOG.
For further exploration of specific functions of WATCHDOG Local, you can click on the corresponding section for more detailed information.
2. Client Host - Detection Items
Implemented by deploying an agent program on the host server,
including basic CPU, memory, and hard disk detection, as well as dozens of major detection items such as disk arrays and connection counts.
The detection items for host servers will be detailed in the latter part of the chapter.

The WATCHDOG system provides numerous detection functions for host servers,
from basic CPU, memory, hard disk detection to disk arrays, connection counts, and more advanced detection items and applications.
Through the agent program deployed on the host server, it can collect relevant information from the client host or perform necessary actions,
and transmit these information messages back to the WATCHDOG host for unified collation and analysis.
The main reason for using the agent program is that only the agent program can achieve precise and delicate execution actions,
avoiding unnecessary waste while providing enough flexibility to adjust and change according to the specific needs of the customer.
In addition, a large part of WATCHDOG's design philosophy emphasizes future scalability. In the design, each agent program operates independently,
using programs to monitor and check each other to ensure system stability while avoiding possible mutual interference.
The following introduces the main monitoring items for host servers,
In addition, there are many other more in-depth detection items and applications for host servers, which will not be discussed in depth here.
