[Ganglia-general] Ganglia store the monitoring data

[刘宁]

Hi, I'm not very clear about how the monitoring data stored in the rrd from 
Ganglia. Can someone explain it to me?
Thanks!

Re: [Ganglia-general] Ganglia store the monitoring data

It goes like this:

- Ganglia agents (gmond) push data (over UDP) to designated cluster
headnodes (same gmond daemon, only configured to accept UDP data).
- the most recent data is accumulated in memory on these headnodes
- gmetad must be configured to periodically pull data from one (or more) of
these headnodes
- gmetad can poll multiple clusters at once (each with multiple headnodes)
- gmetad stores data in RRDs
- web frontend is used to display generated rrds

That is the basic setup. This setup is based on unicast addressing,
multicast can be used too (I have no experience there, never used it).

[Ganglia-general] Ganglia web question

[Sergey]

Hi Everybody!

I’m new in Ganglia.
In my current configuration I see that Gweb and Gmetad services are running on 
the same machine and all data is collected on this machine in RRDS storage.
Is it possible to keep all data only on Collector machine with Gmetad and RRDS 
and access to it from Gweb remotely?
If yes - what should I change in conf.php in Gweb configuration and what should 
be done on Collector machine?

Thanks!
Sergey
