Xymon version: 4.3.5
Hi all, We generate an only RED or PURPLE page through the xymongen --nongreen-colors=red,purple option.
The page generates fine however when a client that has a purple test alongside of a yellow test xymongen seems to drop the
client from the generated list. The client will still be part of "Current non-green systems" with its Purple and Yellow tests
A colleague of mine thinks he has found where our problem comes from.
This is based off the 4.3.16 code base.
We run xymongen with the -nongreencolor=red,purple flags to have an Operations view that hides yellow alerts, but is meant to display all red and purple alerts.
Our issue is for a sample Xymon client we might have a single client side test go into a purple state and also have one or more yellow statuses and this client will not be displayed in the "nongreen" page at all.
In process.c (line 44) the logic uses a simple greater than comparison to determine the maximum "nongreencolor" of the host, so in our sample, this would be set to COL_YELLOW.
In pagegen.c at line 1152, where the each host is being inspected to see if it is a candidate for inclusion in a page, the logic for setting "useit" uses the xymongen option of nongreencolors (which is a bit-shifted 1's complement) against a computed binary version of the host_t->nongreencolor. In our sample case, this means that the host_t->nongreencolor=COL_YELLOW and is currently excluded as we are not including Yellow's.
One method of resolving this which seems to work is to make the host_t->nongreencolor to be a bit-shifted one's complement of the all the entry_t->color of the tests.
