Hi David,

Thanks for that info - just changing the necessary cfg files & renaming the rrd files to databases.*.rrd worked perfectly.

Thanks Dave

David,

Hi all,

I am battling with trying to get a graph to appear on the trends column.

What I have is a custom test appearing in it's own status column - specifically "databases". The data as well as the graph is correct in it's own status column, but don't seem to appear on the trends column with the other graphs. There is probably something obvious that I am missing, but can't get this working correctly.

I have changed the hobbitserver.cfg where

TEST2RRD="cpu=la,disk,.........,nparts,databases"

GRAPHS="la,disk,.........,nparts,databases"

The graph is defined in hobbitgraph.cfg as follows :

[databases]

        FNPATTERN ^database.(.+).rrd

        TITLE Database Transaction Rate

        YAXIS Transactions(R+W)

        DEF:nt at RRDIDX@=@RRDFN@:numtrans:AVERAGE

        LINE2:nt at RRDIDX@#@COLOR@:@RRDPARAM@

        GPRINT:nt at RRDIDX@:LAST: \: %5.1lf (cur)

        GPRINT:nt at RRDIDX@:MAX: \: %5.1lf (max)

        GPRINT:nt at RRDIDX@:MIN: \: %5.1lf (min)

        GPRINT:nt at RRDIDX@:AVERAGE: \: %5.1lf (avg)\n

What is the name of the RRD file? Using basic * wildcarding, is it databases.*.rrd or database.*.rrd - the RE above leaves that ambiguous because '.' will match any character not just a dot. If it is in fact database.*.rrd that could be the problem.

I had a similar issue a while ago - see http://www.hswn.dk/hobbiton/2009/05/msg00149.html

In a nutshell, trends seems to require a file to exist of the form 'graphname.*.rrd', but it doesn't have to be a real RRD file!

David.

I assume the above to be correct (as well as other configurations that I have changed), because the status column for databases has the data & graph displayed as it should (below)

     DB STC       Reads     Writes

     ADADB021          0          0
     ADADB029          0          0
     ADADB030        200          0
     ADADB031          0          9
     ADADB032      20012          0
     ADADB040       1723         14
     ADADB050      67564       1816

Status unchanged in 1 hours, 2 minutes Status message received from 127.0.0.1 Client data <http://10.17.0.50/hobbit-cgi/bb-hostsvc.sh?CLIENT=mf> available

I have changed my bb-hosts file to include :

x.x.x.x mf # TRENDS:*,databases

But that doesn't work - as no graph is displayed for the databases on the trends column.

The only way I can get the graph to appear in the trends column is to change the bb-hosts to something like the following :

x.x.x.x mf # TRENDS:*,cics:cics|databases

The databases graph then appears on the trends column, but this is not quite what I want to do. However, doing it this way then provides a different restriction. If the cics graph only has 4 cics sessions that it is reporting on, and the databases graph has 7 databases that it is reporting on, when the graphs are displayed on the trends column, the cics graph is correct but the databases graph only displays the first 4 databases (below) instead of all 7 databases (above).

Any assistance would be appreciated.

Regards

Dave
