zabbix stand-alone multi-instance monitoring scripts redis

zabbix stand-alone multi-instance monitoring scripts redis

The company save costs and make full use of resources, deployed single instance multi-line situation.
As a python novice, decisively I decided to write a very low script, and then implement monitoring.

The following script implements, discovery automatic discovery, then realized, automatic reporting and other monitoring functions of information through a status monitor.
Which is very low place that script on each host must be defined redis local information, such as ports, passwords and the like; in fact, this can be obtained by configuring the center, but because sharing it, so I wrote the example of a defined ; there are generally a little big God to write their own socket to send data, I have here is very simple, through the shell, using a simple easy way.
