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 = <IOSTAT>;
close IOSTAT;
@collect = grep {!/^$/} @collect;
@data = split(/\s+/,$collect[-1]);
$read_ops = $data[3];
print "<perldata> <hash> <item key=\"data\">$read_ops</item> <item
key=\"Read Ops\"> </item> </hash> </perldata>";
--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 = <IOSTAT>;close IOSTAT;@colle
ct = grep {!/^$/} @collect;@data = split(/\s+/,$collect[-1]);$read_ops =
$data[3];print "<perldata> <hash> <item k
ey=\"data\">$read_ops</item> <item key=\"Read Ops\"> </item> </hash>
</perldata>";'
--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.
