Hi,
I'm a bit late tot he party.
Thinking about it, it's a pretty obvious requirement, to have some statistics
about the jvm reported regularly.
I think it should be pretty easy to spin up a Source Component for that, e.g.,
using the library noted by chris.
This source could the be polled repeatedly with whatever frequency you want.
If you like to do so, chris or I can give you some further hints about that as
we both already implemented sources for edgent.

Hi Felipe,
If you want to access CPU, Memory and Disk usage, you could have a look at
this library:
<dependency>
<groupId>org.fusesource</groupId>
<artifactId>sigar</artifactId>
<version>1.6.4</version>
</dependency>
I am using this in another project and it's working nicely. I'm using is in
a Scala Akka Actor, but it shouldn't be difficult to see how to use it in Java:
https://github.com/chrisdutz/RAPIRO/blob/master/server/telemetry/src/main/scala/de/codecentric/iot/rapiro/telemetry/actors/TelemetryActor.scala
... but thinking about it ... I think it would be a great option to add a
Edgent Source providing such data.
Because with this, you could eventually create data-streams that adapt to
the load on the Edge device ...
It shouldn't be hard to implement ... and as I posted in my reply on the
other thread, I don't think Edgent currently has something like that. I just
did a quick full-text-search and couldn't find anything?
Feel tempted to implement such a connector? We're currently trying to
re-initiate the committer-base of Edgent and contributions like this would be
highly valued :-)

Hi,
On the Edgent documentations is mentioned:
"You can send data from an Edgent application to your back-end system
when
you need to perform analysis that cannot be performed on the edge
device,
such as:
Running a complex analytic algorithm that requires more resources, such
as
CPU or memory, than are available on the edge device." (
https://edgent.apache.org/docs/overview)
I understood that the Edgent daemon on the device is constantly
monitoring
its properties (CPU and memory) and this daemon decides to not perform
the
analytics on the RPi when it has lack of resource but perform on a layer
above. Is it right?
How can I implement a program using Edgent to send this type of
metadata to
a layer above? Let's say I want to sent metadata regarding CPU, memory
and
storage usage from the RPi to an IoT gateway.
Thanks,
Felipe
