I'm afraid you can't make functions (like a normal programming does) in
cfengine.
To get closed to your expectation, you might need to create global variables
(bundle common) of the outputs of your commands/scripts then you could call it
up in every bundle. For instance;
body common control

Thank you Nakarin .. a lot!

Has anybody out there ever tried scaling up a cfengine server (v2.1 or
v2.2) on a really big, fast server? I'm thinking on the order of 4
sockets, 24 cores, and a 10Gbit NIC.
This is to support a particularly massive (and temporary) flood of
cfagent requests to synchronize their local policy.

I'm talking about 5,000 systems each updating about 50MB of policy data
over a 1-2 hour span.

I think the issue is where Linux can support this many cores. My understanding
was that
the Linux kernel was limited to 8 cores, but this is only hearsay.

Agree 100% on what you're saying here. And if this was a permanent
load, this would be the route I'm taking. But I'm talking about
supporting this level of load for a very short period of time (we're

Nah, Linux supports up to 1024 cores, depending on the distro. And with
TCP offload technology and memory-mapped I/O in modern 10Gbit NICs, you
can saturate a 10Gbit link without even pegging a CPU. The linux

As others have said, Linux supports many many more cores than that, and has

You would seem to be the first to try this ;) I hope you write a paper.

Then I'm not sure what my friend was talking about. As long as you increase the
max
connections to allow threads, it's up the libraries. Cfengine doesn't care how
many
connections you have, only pthreads.

I'm running Cfengine Nova and I'm now going back to some measurements
promises I worked on a while back. I've now recalled that whenever
measurements promises change, cf-monitord needs to be restarted. So I'm
trying to determine how I can restart all of my hosts' cf-monitord
processes.

Thanks for the responses everyone. I'm going to discuss the options with
my colleagues and our operations center that manages our Zenoss
configuration.

The normal thing is to use cfengine to restart the pieces when the policy
changes
by seeing when a copy occurs from the policy server.

Thanks, Mark. I actually thought about doing that and that's one of the
things led me to notice that Cfengine restarts itself at 5 AM in
process_matching.cf. However, since by default the process_matching
bundle is evaluated before any of my custom bundles and in general it's
not a good idea to mes
I am not completely up to date on the latest update.cf, there has been a lot of
development there for Nova. If you think something is missing there, I would
report to to

Ah, gotcha. Thanks, Mark. I'll open a ticket on this.
