With item pre-processing added to LLD workflow and new javascript pre-processing step, it’s possible to monitor a directory for its file changes.

Apache performance and understanding /server-status metrics Apache Statistics Module: mod_status Understanding website performance and Apache uptime should begin with external monitoring, i.e. Zabbix, which allows you to discover problems from a user’s perspective. Such problems involve:

With new preprocessing steps added to Zabbix in nearly every release, it became obvious that it’s impossible to predict every business case, so we had to come up with a universal solution. This, in turn, raised an important question – which embedded scripting language/engine to use.

There are a few ways one can gather custom metrics with Zabbix, for example, via user parameters or Zabbix sender protocol. While either method can work for simple metrics, creating a more wholesome approach (with data collectors, persistent connections etc) and interfacing it with Zabbix may not be as trivial.

Macros are variables that can resolve to a specific value depending on the context and location inside Zabbix. Effective use of macros allows to save time and make Zabbix configuration more transparent.
