Re: [Ganglia-general] Restful Api for Ganglia Database

Nick,

Any Ganglia graph can be exported in either CSV or JSON by appending

&json=1

or

&csv=1

to the graph URL.

Hi Jon,

I think you misunderstood me. All I referred to was a git commit log entry to a pull request that added support for responding to HTTP requests with current metric data. The relevant GitHub pull request does not include any documentation https://github.com/ganglia/monitor-core/pull/60

What I think Azaz wants so that he could develop his own dashboard, and what has not been officially implemented, is an historical metric REST API. There was a Google summer of code proposal to look at a more advanced (non-historical) metric API (see https://github.com/ganglia/monitor-core/wiki/GSoC-2014-project-ideas#api) but there we no takers as far as I know.

If anyone has some code they'd like to share with the Ganglia community that implements an API that presents historical metric data (ie. perhaps sourced from the RRD's or stored some other way) then please do. It doesn't matter how bad you might think your code is, it would be a start and people can then build on that.

Regards,

Nick

Nick,

Can you please resend the link to the restful interface documentation. I did not see it and ended up implementing my own,

But I’d really rather use the official.

Thanks,

jon

Hi Azaz,

If by RESTful you just mean "accessible via HTTP" then this is already possible [1]. Note, that this API interface is readonly so only GETs are allowed. Also note that this is not historical data. It is the most recent collected value for every metric -- in XML.

If you wanted historical data accessible via a HTTP API then you would need to develop something yourself -- I don't know of any working examples but there may be others on this email list willing to share their work if asked.

Regards,

Nick

Hi,

I need to write restful services which should return metrics data from ganglia database. So instead of using web front end provided by ganalia, I need to integrate my own dashboard with ganglia database.

I have searched but it seems that ganglia did not provide restful services to access its database. Kindly let me know how to achieve this?

Thanks
