[Xymon] Xymongen - clientlog column - bug?

Hello,

Using the Terabithia 4.3.30 RPMs, the Xymongen web page shows some statistics
such as the total number of status messages, and their breakdown into how many
were green, how many red and so on.

In looking at the source code where the number of status messages is counted up
though, I am a bit confused. The code shows:

=======
        /* Count all of the real columns */
        if ( (strcmp(testname, xgetenv("INFOCOLUMN")) != 0) &&
(strcmp(testname, xgetenv("TRENDSCOLUMN")) != 0) ) {
=======

In other words, this says add up the number of green, red etc messages except
for the 'info' and 'trends' columns. This makes sense as these two columns do
not test anything, they just report known information.

My question is why is the 'clientlog' column not also excluded? It too does not
'test' anything, but just reports the data sent by the client.

In trying to work out the number of tests we have I have been checking the
'/var/lib/xymon/hist' directory. Looking just at test names, in our case, we
have 1165 test results. However, the xymongen web page shows 1215 status
messages.
By modifying the code to include a count of the clientlog messages on the
xymongen web page, this shows 50.
Now, 1215 - 50 = 1165.

So, as far as I can tell, the number of status messages being displayed is
incorrect. It is higher than it should be. I can submit a patch to correct
this, it's just a one-line change, but I want to be sure that it is actually a
bug.



John.
