Custom remote monitoring using cacti and performance counters (1)

CactiThere are many features that you may not know. This article introduces one Method: Using cacti andPerformance countersImplement custom Remote Monitoring

Performance monitoring has always been an issue that every website must seriously consider. For a large system, if you do not know the running status of each module, it is an accident, I don't even know how to cancel it. I think many software developers have noticed this. Therefore, various monitoring data, such as the number of web connections, request concurrency, and database connections, are added to the corresponding web and database products, for your use. In addition, when the system is distributed on multiple machines, the distributed monitoring problem is highlighted, so cacti came into being. Through the SNMP protocol, cacti can easily read snmp data from multiple machines at the same time to achieve distributed monitoring.

If you are new to cacti, it is recommended that you go to the cacti official website to learn about this product (http://www.cacti.net /).

However, sometimes the predefined monitoring values provided by systems, web, and databases are insufficient. In many cases, we need to define specific monitoring values to monitor our systems. You may first think of performance counters. performance counters can be easily defined through custom category and counter to implement and monitor specific values. For a solution for customizing performance counters, see:

However, if you want to view the performance counters, you must log on to the used machine and use the system's performance components. Wouldn't it be perfect to achieve remote monitoring by combining cacti and performance counters?

After the help of the major search engines, found a library to achieve similar functions: http://erwan.l.free.fr/snmptools, and broke through the firewall restrictions, through the proxy finally came to this precious stuff .. To facilitate the download, this tool is available for reference in this article.
