Neither Diego nor myself run an x86 machine so nobody tested it if it
works. If it works for you let me know,

Is there a reason it is not ~x86 masked? or even hard masked for x86?

gearmand now available in gentoo

2009-12-20T20:57:43Z

Diego Pettenò and myself pushed the gearmand into portage, install
with emerge -uDNva sys-cluster/gearmand
Currently we dont allow building against libdrizzle (tests fail on us
for now) and libpg, but this is hopefully corrected soon.

Hi Brian,
damn I missed that in the bugzilla. Oh well ... Together with Diego
(Flameeyes) we put together a working ebuild along with init scripts
for gearmand and pecl-gearman. It's in Diego's overlay

We have several ebuilds in the bug list and hope to get one pushed
through soon. We use daemontools, but I am not sure if we created an
init script or not.

Well, the libraries are all different, but most should if it is
configured with more than one server.

You can't count jobs in cacti as there is no counter in the stats. This
is on the roadmap, but not there yet.

I responded to a similar question in this thread with details of how
we monitor gearman workers with Nagios using the Administrative
Protocol.

1. The worker takes a single argument. Since I use perl primarily and I want
to transfer data structures I usually serialize with Storable. But I would
use JSON for anything cross language.
2. I don't know, but I'm gonna guess yes.
3. I've never seen a server monitor. But I have a cron that monitors works

Gearman doesn't care what data you send along with a job. It's up to you to
serialize it on the way in and de-serialize it on the way out. As long as
your client and worker(s) agree on how that works, you should be just fine.

Gearman architecture queries

2009-12-19T14:39:55Z

Hey All,
I am new to Gearman. I have following queries about optimized Gearman
usages:
1) I think worker expects job as a "string". Can I send an Array or
Hash as Job to worker? If not, is JSON the best Job format to send
Array/Hash?
2) Can I attach rails application routes as worker for Job Server?

FYI, I just submitted this:
Title: Front end database optimization using Gearman
To ensure high performance in modern web applications highly relational,
normalized databases have to some times be optimized (or denormalized).
Marshaling this data back and forth from the primary database server
to the front end database servers can be a tricky task.

Yeah I have an older libevent. I'll try updating that and see if the problem
goes away. Thanks.
I would enable the log function to see details, but my guess is you
don't have libevent 1.4 or later. Previous versions of libevent were
not thread safe, so you can only run single threaded if 1.3 or earlier.

btw, does anyone have experiences on running two job servers alongside
each other on a single machine for high availability purposes on a
single machine? will the client automatically failover to a different
jobserver if it cant connect to one? i suppose it will but didnt
really try...

For now, use iptables.
