A description of the application scenarioIn the previous article, we described the use of Zabbix to monitor the availability of Web sites in a Zabbix with web monitoring just using the Libcurl library to detect all URLs on the Zabbix server or proxy side. This does not actually check the network quality of each URL that the zone accesses. This article uses the Zabbix lld,pycurl module and Zabbix sender to collect the network quality of each URL that i
