Consider the two functions max (A, B)Different types of A and B have the same processing format:
Return a
Use existing methods to solve the problem:(1) macro replacement # define max (A, B) (a)
Existing problems: Avoid type check
(2) Heavy Load
Problems: Many overloaded versions are required.
(3) Use function templates
Ii. Template

Before learning Django templates, I thought that, like many php template engines, it was implemented by caching file output and executing python code in the template. After reading the template, I found that it is similar to the front-end template and uses regular expressions. In order to better understand the design philosophy, I also referred to the templates in tornato, drupal, codeigniter, aceTemplate,
In the official latest Zabbix 2.4 distributed architecture, there is no support in addition to node mode.I also used node in the 2.x version of the multi-tier distributed node mode has been repeatedly encountered in the server configuration consistency confusion, and repair is very troublesome.So the "Learn from Me series" does not introduce node deployment.The purpose of using the proxy is also obvious: reduce the server's acquisition pressure or cro

Zabbix's "template OS Linux" Templates support monitoring mounted disk space utilization, which is implemented using LLD (low-level discovery) without disk IO monitoring. This article describes the method of monitoring disk IO using the Zabbix LLD function.idea : First create discovery rules, configure the corresponding userparameter on the agent side, invoke the well-written shell script, dynamically find

If the file does not exist, 1 is returned.10: view the file's MD5: vfs. file. md5sum [file]: Check the MD5 of a small file and return the MD5 value (as if only version 2.0 and later has this key) 11: two keys: net. if. discovery, vfs. fs. this template is available in the discovery, windows, and linux monitoring templates
