I discuss it with Greg on IRC. Other may find some information useful: [15:50] <__greg__> the issue I am running into is that a command like iostat returns many data points, however with the documented Generic Program With Data it looks like only 1 of those points can be captured [15:51] <__greg__> unless you know another way [15:51] <__greg__> as it is i need to create two probes (instances of iostat) to capture Read IOPs and Write IOPs [15:51] <__greg__> which is highly ineficient [15:51] <__greg__> *efficient [15:52] <__greg__> it would be great if you could [15:52] <__greg__> or [15:53] <__greg__> handle multiple 's within 1 [15:53] http://docs.redhat.com/docs/en-US/Red_Hat_Network_Satellite/5.4.1/html/Reference_Guide/sect-Reference_Guide-Probes-General.html#sect-Reference_Guide-General-GeneralRemote_Program_with_Data [15:53] you can have more item in one hash [15:54] I'm not sure if you can have more then one hash [15:54] <__greg__> well [15:54] <__greg__> that shows that you can have more then 1 [15:54] <__greg__> but what about mor ethen one item key="data" [15:54] that is probably not possiblem [15:54] <__greg__> Ideally i would like to emulate what the Linux: TCP Connections by State does [15:55] <__greg__> which is very advanced [15:55] <__greg__> plotting multiple data points [15:55] <__greg__> and configurable data streams [15:55] <__greg__> then we could just make the IOSTAT probe [15:55] <__greg__> and let users pick which of the 15 fields it records give [15:56] <__greg__> do you see where I am coming from ?

Re: [Spacewalk-list] Generic Program with "multiple data" points
Not entirely sure why, but the mailing list is stripping out parts of my
included script around @data making it inoperable.
Please excuse the appearance.

Subject:Generic Program with "multiple data" points
Hello,
Is it possible to have multiple data categories and data points in a
"Generic Program with Data" probe similar to the built in "Linux: TCP
Connections by State" ?
For example:
I wrote the following perl script to extract read IO/s from monitored
hosts into data points:
--SNIP--
#!/usr/bin/perl
open(IOSTAT,"-|","/usr/bin/iostat -xtd sda 15 2") or die;
@collect = ;
close IOSTAT;
@collect = grep {!/^$/} @collect;
@data = split(/\s+/,$collect[-1]);
$read_ops = $data[3];
print " $read_ops";
--SNIP--
Converted here into a "Generic Program with Data" probe (1 liner)
--SNIP--
/usr/bin/perl -e 'open(IOSTAT,"-|","/usr/bin/iostat -xtd sda 15 2") or
die;@collect = ;close IOSTAT;@colle
ct = grep {!/^$/} @collect;@data = split(/\s+/,$collect[-1]);$read_ops =
$data[3];print " $read_ops
";'
--SNIP--
What I would like to do is create more data points out of different
streams of data from the -1- probe.
In my script the iostat output captured in @data has read io/s as element
[3], while write io/s are captured in element [4] (etc).
Going back to my reference to the Linux: TCP connections by State probe;
in that you can specify multiple data point sources: eg, ESTABLISHED,
TIME_WAIT, SYN_RECV etc.
This would be preferred as then I could process all the data from the
iostat probe and create very powerful reports. I just dont know if that
is possible as my current experiments have yielded no success.
