Re: [Ganglia-general] GSOC 2015: Student Introduction
Hello Daniel, If you would like, I can suggest some activities to help you get to know Ganglia or use Ganglia with PostgreSQL Looking in Google, I found some PostgreSQL metrics for Ganglia but at least one of those projects clearly states it is no longer maintained. It would be particularly interesting to a) see this implemented in C as a Ganglia module (see ganglia-modules-linux for examples of Ganglia modules written in C) b) make a generic module that can run any database query and return the results as metrics Do you mean a module to interact with the database in Postgres to run queries? One particular thing to keep in mind is that Ganglia prefers metrics to return rates or delta values rather than raw values. E.g. if PostgreSQL has a metric that returns the total number of queries since PostgreSQL started, then a metric module should sample that value at regular intervals and calculate the rate (e.g. number of queries per second) and that is the value that will be transmitted through Ganglia, stored in the RRD and charted. I get the context, but any reason as per why this happens in metrics than raw values? Another area you could look at is gmetad. In version 3.1.0, module support was added to the gmond component but there is currently no module support in gmetad. If you want to learn a little bit more about dlopen then you could study how it is done in gmond and then try to implement a similar API for gmetad to support plugin modules. In gmond, modules are used for inputs - polling the metrics. In gmetad, the modules would probably be used for outputs, e.g. gmetad would call each module with different events (metric received, new host detected, host appears down, etc) and the modules could then do things like writing the events to databases or sending them to other infrastructure or message queues. Let me do some more research on gmetad, could you redirect me some useful wikis to read?

Hi Hitesh, Thanks for your email. We are just waiting for Google to confirm if Ganglia will participate in GSoC this year. They will publish a list of participating organizations next week.

Re: [Ganglia-general] GSOC 2015: Student Introduction
Hello Daniel, Yes, I know the list will be out on 2nd. But I am interested to know how can I start with these two projects. I wanted to contribute, not just because of GSOC but because they caught my interest. So if you could guide me on how to get started, I would be willing to be a long term contributor. --Hitesh Date: Tue, 24 Feb 2015 11:26:09 +0100 From: dan...@pocock.pro To: hiteshram...@hotmail.com; ganglia-general@lists.sourceforge.net Subject: Re: [Ganglia-general] GSOC 2015: Student Introduction Hi Hitesh, Thanks for your email.
