Where is the client data stored in hobbit server? 🔗 link

Hello,

In the some html outputs of the each test there is a "Client data" link and
of course its data with it.....

I would like to implement a customized script to parse all the lines of the
"Client data" and send an alert if certain keyword matches. I think it would
be nice because you don't have to implement it in all the client
sides.....Definitely there are many people who are interested in it ???
And I can't figure out where the data is stored in the hobbit server side.


My question is,,,,Where is the "Client data" stored in the hobbit server
side? Please help me with finding it...

Hi,

 
the hostdata are stored in the data/hostdata/<hostname> directories...

 
But I think it's only saved if a red condition exists for that host.

Thank you, Johann,

I also was able to locate the directory with some part of the client data.

But I was also wondering maybe there should be the stored real time data
somewhere at least 5 minutes(client interval),,, or you can't view the real
data in the html.....

There are two ways you can do this.

1) You can use the command
      bb 127.0.0.1 "clientlog HOSTNAME"
   to fetch the current client data, then do your processing.

2) (My recommended solution) Write your script as a Hobbit server-
   side extension, and run it on the server as
      bbcmd hobbitd_channel --channel=client YOURSCRIPT
   Your script would get all of the client data fed on STDIN,
   beginning with a line "@@client...|HOSTNAME|..." and 
   ending with "@@". Try running (as the hobbit user)
      bbcmd hobbitd_channel --channel=client cat
   and watch the data that is generated.

We're starting to move to the new IBM P6 environment, so I started
looking at backing the 4.3 do_vmstat.c into 4.2.

This pretty well showed I'm not a C programmer.

However -- I added the two additional fields, cpu_ec and cpu_pc to the
AIX structure in the 4.2 do_vmstat.c, recompiled, and the result works
with the new P6 box. It will also work with new P5 or earlier systems,
as the two extra values will just stay at <NAN> in the RRD. For existing
older systems, I used 'rrdaddsource' from the RRD web site to add the
cpu_pc and cpu_ec datasets to my existing RRD and everything is working
just fine.

I did have to change the vmstat_ec and vmstat_pc graph entries -- the
4.3 code is doing a multiply by 100 that doesn't seem to be required.
The pc value is actual physical CPU usage and the ec value is percentage
of entitlement. In the short list below, this system is using between
0.01 and 0.02 physical CPUs and running between 7 and 17 percent of the
entitlement (set at 0.10 CPU)

Thanks for such a GREAT tool!

The AIX Doc on the two fields:

Beginning with AIX 5.3, the vmstat command reports the number of
physical processors consumed (pc), and the percentage of entitlement
consumed (ec), in Micro-Partitioning environments. These metrics will
only be displayed on Micro-Partitioning environments.

pc 	Number of physical processors consumed. Displayed only if the
partition is running with shared processor.
ec 	The percentage of entitled capacity consumed. Displayed only if
the partition is running with shared processor. Because the time base
over which this data is computed can vary, the entitled capacity
percentage can sometimes exceed 100%. This excess is noticeable only
with small sampling intervals.

And sample vmstats from my test system:

kthr    memory              page              faults              cpu

The AixPower5 is where I ended up, except that I'm not stripping the
decimal point in do_vmstat.c. The vmstat_ec values look correct, but the
rrd dump shows a value of zero for vmstat_pc instead of the expected
1.00000000e-02. 

Time to play around a bit more; I'll add the decimal strip code and see
what I get as a result.

Thanks for the pointer to the AIX tips -- I've got an Oracle DBA that
will enjoy the memory graphs. I obviously need to spend more time
looking around :-)

I have lots of AIX enhancements (etherchannel, errpt, DS4 statitsics, iostat,

I can not publish the scripts and information because this will not make my 
boss not happy :(

Henrik,

Thank you very much!! The information is really helpful for me not only to
implement the script but to understand the hobbit design.

I really look forward to the version 4.3.0 release. ( Hope all the regex
work fine !! ).
