Custom report showing weekly Average/Max valuesfor CPU/RAM/SWAP/Availability

[Ayotunde Itayemi]

Hi,
Thanks for the response. I will look into the RRDTool command line
option.
Yes, I am using NDOUTILS. I have actually examined a few of the tables
and it looks like the base values that can be manipulated are in there
(somewhere :-).
I have looked at the NAGIOS email reporter and it's not what I want. In
fact, I have implemented the same thing it does myself - i.e., query the
standard NAGIOS cgis. The issue with this output is that what you get
from the CGIs are not the performance data values, but the percentage of
the time a particular measurement is over the warning/critical
threshold. 
By the way, are there comprehensive entity-relationship type diagrams
for the tables making up the NDOUTILS tables anywhere?

Thanks.

I don't use PNP but I expect this will be work for you unless it has  
built-in reporting for this (I don't believe it does). I would  
encourage you to learn more about how RRDTool works by reading the  
Documentation and Tutorials at
http://oss.oetiker.ch/rrdtool/index.en.html 
. That will give you a good basis for the concepts you will need to do  
do this. To obtain the textual values for these parameters, you'll  
need to use the command-line rrdtool program to fetch the values from  
the rrd files directly. rrdtool can fetch the AVERAGE value at each  
stored point during the week and you'll need to add those up and  
divide by the number of values to determine the single average value  
(man rrdfetch). You could also pick the MAX value from that output or  
maybe PNP also includes a MAX rra you can fetch.

Nagios Email Reporter might be the ticket here.

There are no databases or tables to query unless you're using NDOUtils  
and even then, getting this information wouldn't be trivial, IMHO.
