Description:

With this ZenPack you can monitor the status of your redis server and the databases it provides.  It connects to the redis server and collects various statistics.  This ZenPack provides:

 

  • Bare /DB/Redis EventClass
  • Redis Database template
  • Monitoring script
  • Graphs and associated datapoints
  • Each database provides datapoints for its keys and expires

REQUIREMENTS:

     Zenoss Version: tested with 2.5.1

     ZenPack Dependencies: None

     External Dependencies: None

 

     Installation:

  1. Install the ZenPack using the standard methods. (webui, or zenpack --install)  You should restart Zenoss afterwards.
  2. Apply the template found at /Devices/Templates/Redis Database Server to your redis server, or a Device Class in your tree.  For information on Performance Templates and how to bind them, read the Official Administration Doc section 5.2.1

Features/Synopsis:

 

After applying the template to your server or Device Class, Zenoss will periodically connect to your redis instances and gather the following statistics:
  • Redis version
  • Uptime in seconds
  • Connected Clients
  • Connected Slaves
  • Used Memory
  • Changes Since Last Save
  • BG Save In Progress (boolean)
  • Last Save Time
  • Total Connections (since start)
  • Total Commands (since start)
  • Role (master/slave)
  • Per-database Keys Count
  • Per-database Expires Count
  • Several others...

If you upgrade your redis databases, newly added metrics will be provided automatically to the collection statistics, although you will have to add the datapoint to the template.

A few of these metrics are used to create 4 basic graphs (seen at the top of this document), but you should customize graphs and thresholds for your application's needs.

Change   History:

  • 1.0.1 initial release

Known issues:

  • This zenpack provides "keys" and "expires" for all database on the redis server.  The command template provided will output each database metric in a datapoint named by the pattern db#_keys or db#_expires.  So if you are interested in monitoring db10, for example, create a new datapoint named db10_keys and db10_expires.
