Subject [jira] [Commented] (ACCUMULO-3903) Add ability for Accumulo to store and display external Htrace traces in the Monitor pages
Date Tue, 16 Jun 2015 17:02:00 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3903?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14588374#comment-14588374

Josh Elser commented on ACCUMULO-3903:
--------------------------------------

IMO, the monitor isn't going anywhere, but if we could offload the trace viewer, that'd be
an improvement. It's not heavily tied to the monitor now so as it is. I think there's merit
in trying to move towards a single system -- that's just more work than you originally outlined
and I didn't want to try to sign you up for something you didn't intend. :)

I'd be a little concerned about forcing users to deploy two apps instead of one, but that's
something we could address (serve up multiple WARs in an embedded server). Not a blocker.

> I would like to use Accumulo as the central store of trace information for my whole system
(of which Accumulo is also a component). I am currently integrating the existing Accumulo
HTrace trace implementation into one of the other components of my system. I would imagine
that this would be also useful for other people to use in tracing their whole system.
> As such, I would like to be able to use the existing trace pages in the Monitor for displaying
all these traces. I would like to add the ability to filter the traces that are displayed
to particular system components (services) and/or hosts. This could be implemented using either
a drop down or filter textbox to filter client-side the already de-serialised records.
> There are a number of existing tickets that relate to this work that could be done as
part of this work which would centrally position Accumulo as an enabler for tracing functionality
for a whole system, they include:  
> # [ACCUMULO-1198|https://issues.apache.org/jira/browse/ACCUMULO-1198]
> # [ACCUMULO-1013|https://issues.apache.org/jira/browse/ACCUMULO-1013]
> # [ACCUMULO-3005|https://issues.apache.org/jira/browse/ACCUMULO-3005]
> Also, even though the Accumulo Trace implementation can be used by other components pretty
much straight out of the box, it does require the accumulo-site.xml file for it to work. This
probably could be refactored to not require all the site.xml for the trace server to work
but some other trace config file. 
> Thoughts?
