<ruebot>is there a performance and scaling call today?10:58
<jrgriffiniii>I assumed so11:04
ruebot: (I'm currently on the call, at least one other is in attendance)
* mohamedar1 leaves11:06
<ruebot>jrgriffiniii: ok. i'll jump on then.11:07

<whikloj>acoburn: ping14:52
<acoburn>whikloj: pong14:53
<whikloj>acoburn: can you point me in the direction of a good way to check memory usage in a Camel route?
if such a thing exists
<acoburn>whikloj: have you ever used hawt.io?
<whikloj>acoburn: yes using that now, but not getting memory info, or maybe not looking in the right place..14:54
<acoburn>whikloj: I'll check, just a sec
whikloj: you mean a _particular_ camel route, right?15:00
whikloj: as opposed to the entire camel runtime?
<whikloj>acoburn: yes
acoburn: though the camel runtime on my particular machine might be okay too
<ajs6f>whikloj:acoburn: Sounds like a job for JMX.
<whikloj>ajs6f: yeah I looked but the JMX "properties" don't seem to cover memory15:01
ajs6f: mostly thread size, route received, processed, failed, etc
<ajs6f>whikloj: No, not JMX on the individual oibjects, JMX on the heap.
whikloj: Open jconsole on your JVM.15:02
<whikloj>ajs6f: oh, yes I have to wait and restart Tomcat with the jmx remote. But that is my next step. I was trying to see if I could do it right now.15:03
^^ jmx remote enabled
<ajs6f>whikloj: Are you not going to run jconsole on the same machine?
<acoburn>whikloj: the "dashboard" portion of hawt.io shows memory info about the heap
<whikloj>ajs6f: Will it run in a terminal environment15:06
acoburn: thanks, I guess that is probably my best option
<ajs6f>whikloj: Is the JVM hosting Camel on the same machine as the one on which you are going to run jconsole (or other JMX probe)?
<whikloj>ajs6f: normally no, I run jconsole on my workstation.15:07
<ajs6f>whikloj: Oh, okay. If they are on the same machine you can avoid tinkering with the remoting stuff.
whikloj: Might be worth using X/Windows. That's what I do.15:08
<whikloj>ajs6f: yeah, feels like I am building a mountain of work just to confirm that my camel route is more memory efficient than ol' Gsearch15:09
or maybe https://github.com/cjmx/cjmx15:11
* jrgriffiniii joins
<ajs6f>whikloj: A) Efficient != always is using less memory. Efficiency is a ratio. What is your numerator and denominator? Instant memory usage per instant throughput? Average memory usage per average throughput? Memory per indexing action? These are all different. B) Suppose Camel is _not_ more efficient. What does that mean?
<whikloj>ajs6f: more on a per action basis. If I index 1000 documents with GSearch and then with my camel-route, which a) is faster and b) uses less memory to create the same result.15:12
* aelkiss leaves15:14
<ajs6f>whikloj: What is "uses less memory"? Instantaneous maximum total heap? Average total heap? Instantaneous maximum heap per document? Average heap per document?
<whikloj>ajs6f: I'd probably say average heap per document or possibly average total heap, but my understanding of the whole java heap concept is limited15:15
<ajs6f>whikloj: Heap is almost all memory allocated to state.15:16
whikloj: Total heap is going to include overhead from various sources, so the comparison will be harder, but on the other hand, heap per document is going to be harder to measure, because it's a more transient observation.15:17
whikloj: Choose you poison.
<whikloj>ajs6f: arsenic....oh you meant...I got it.15:18
* jrgriffiniii leaves
<ajs6f>whikloj: No, I was thinking of http://www.last.fm/music/Poison:: "There are at least 6 bands with the name Poison:"15:21
<whikloj>ajs6f: Ahhhh yeah, as a child of the 80s I appreciate Bret Michaels' sweet lyrics.15:22
* jrgriffiniii joins15:23
<ajs6f>whikloj: I think we should start including album covers with releases. This is inspiring: http://www.amazon.com/poison-album-list-order-release/lm/R3BSZEH0CI3Q7815:24
* jrgriffiniii leaves15:28
<ajs6f>This is actually a really good idea. It would invite participation from the community. It would enable contribution from non-programmers.15:31
* jrgriffiniii joins15:33
<whikloj>We could have a battle of the bands. Poison vs Cinderella, Dokken vs Warrant15:44
