Version 1.1 has been released incorporating changes from Howie that allow for a more expansive use of the data that the plugin provides via either additional plugins, or new Graph Templates.
Please find the following user contributed plugin called DSStats. This plugin is an infrastructure plugin. What this means, is that you see nothing but slowed polling times by installing it, or at least on the surface.
However, if you are currently creating aggregate graphs and your savvy with SQL, you can now write script queries, that perform database calls to build those graphs further enhancing what we can already do with Aggregate and RRDtool.
Oh yeah right you say. Well how about a few examples. Let's say you are tracking the temperature of all equipment in a rack of servers, and want to know the average and peak temperatures within that rack, and you have some "MetaData" that tells you that so and so servers are in that rack.
Another example, would be to total all network bandwidth utilization within a state, city, country, floor, building, yah da yah da yah. Now, you can do it with a simple SQL query that sum's all data.
How about the top 10 Gigabit interfaces out of 10,000 in your company, either in the last hour, day, week, month, year. Now you can build a plugin that does that in an instant.
Well, I would like your comments, and donations to the Cacti Group. If you can spare it, please consider donating 10-100 dollars to the Cacti Group each year. It pays for lot's of beer and cider and keeps us going. Seriously!
And of course, before you turn this plugin loose, you must keep in mind the following:
1) The plugin uses two memory tables, do make sure you have enough memory to handle them.
2) If your poller is borderline in terms of making all polling in a poller cycle, then don't enable this without being prepared to immediately disable it.
Finally, good luck. Enjoy Cacti.
