Custom graphs

[Kern, Thomas]

I have two non-linux systems that I have a specialized client on. On one
of these systems, I have a special test for the CPU utilization of
logical partitions. I used the NCV method of getting the data
(LPARname:CPUvalue) into the RRD files supported by Hobbit. I have been
able to add a graph to the status page for the LPAR column with a graph
definition that lists each of the known LPARs in this system and the
total value that is also sent. This has been working for several weeks.
Now I am trying to add the second system. It has a different set of LPAR
names. These LPAR names must be unique across our organization. 

I asked our Hobbit admin to update the hobbitgraph.cfg with a modified
[lpar] definition that included the second system's LPAR names in the
hope that RRD would simply say that those entries from the other system
were 'Not Available' or simply not display anything for them. I had
hoped that I could use ONE graph definition for the [lpar] column no
matter which system was supplying the data. Both graphs had an error
about one of the OTHER's DS entries not being present. Is it possible to
have two graph definitions for the same column, such as [vm1.lpar] and
[vmhost.lpar] versus a single definition [lpar]?

Here are copies of the two status pages:

Thu Jan 18 10:05:06 EST 2007 General Processor LPAR utilization within
thresholds 
LEGACY:1.0
ZOSEPROD:26.7
ZOSPROD:2.4
Total:30.1
 
Thu Jan 18 10:05:13 EST 2007 IFL Processor LPAR utilization within
thresholds 
IFLPROD:1.3
Total:1.3

Here is the combined graph definition:
