ganglia / gmetric4j Goto Github PK

It would be very useful to read all the default settings from the gmond.conf file if it can be found in one of the usual locations.

It may also be possible to inspect the list of open sockets of any running gmond process to discover configuration details.

Hi~

I found that gmetric4j always send a metric as string but the type that is included in the metadata show actual data type such as double, long.
you can see the code at here: https://github.com/ganglia/gmetric4j/blob/master/src/main/java/info/ganglia/gmetric4j/gmetric/Protocolv31x.java#L138

Is there any reason for do that?

Protocolv31x.java line 39 InetAddress.getLocalHost().getHostName();

On some machine configurations, getLocalHost() throws UnknownHostException
For example, on a developer machine that does not have a static ip address configured into /etc/hosts for the machine host name, this pesky problem prevents gmetric4j from initializing, even when a spoofName is set.

If we skip getLocalHost() when spoofName is set (since localHostName would not be used), there would be a workaround for this situation.

Hello,

I am migrating from metrics 2 to 3.
In the old yammer metrics' GangliaReporter class, there are two String arguments specifying the host and the "ganglia group name".

GangliaReporter(MetricsRegistry metricsRegistry, String gangliaHost, int port, String groupPrefix)

But following their new API, i.e using a GMetric object to configure the reporter, there is only one "group" argument described in the doc as "the host/group to send the event to".

public GMetric( String group, int port, UDPAddressingMode mode, int ttl) 

As I am relatively new to the concepts involved here, do you have an idea how I could specify the old GangliaReporter's host and group arguments into a GMetric Object?

Thanks in advance.

I maintain Metrics which is Apache 2 licensed, and has ganglia as an output. It was brought to my attention that gmetric4j has a dependency on remotetea, which as you know is LGPL licensed. This severely limits its usefulness. Having inspected the code, it seems to me that it would be relatively trivial^{[citation needed]} to reimplement the parts of XDR which are required by ganglia. Is this something you would consider?

I'm getting the following error when sending a metric with 10 attributes. How can I increase this buffer?
I tried changing the udp receive buffer in gmond to 20 mb but that did not help.

In the 3.1 version of the protocol, the spoof boolean is hard set to false.

Hello,

I am currently working on porting jmxtrans (which use your project for a GangliaWriter) to maven but I am facing a problem with the gmetric4j jar version currently used which seems to have been built manually. When I use the last gmetric4j from maven central (info.ganglia.gmetric4j:gmetric4j:1.0.2), I see that the Spoofing Support is missing in the jar.

As the Spoofing Support was recently merged in the master (#4) I would like to know if it is possible for you to release a new version of gmetric4j to have this change in Maven Central ?

Thanks in advance for your response
