Yes, and no.
Have just enabled the status page in the web config, and it appears to have
got rid of the one error message.
(Not sure how I missed the config change at initial install time)
But, I still get the other error
[warn] (128)Network is unreachable: connect to listener on [::]:443
And my graphs still take way too long to render, and send my CPU
utilisation through the roof.
Public holiday here tomorrow, so only back at this client on Tuesday.
Thanks
Vernon

Do you have apache trending graphs enabled? If so, did you enable the
status page in your apache configs?

*Subject:* [Xymon] High CPU Load Rendering Graphs
Hi all
My Xymon server 4.3.10 is burning the CPU cycles when we view multiple
graphs, like the trends page, and takes about 5 seconds to render a single
graph in a single-graph page view.
It's a Sun Fire X4150 with 4Gb of RAM, running Solaris 10 update 5..
Version Location Tag
-------------------------------- --------------------------
Intel(R) Xeon(R) CPU X5460 @ 3.16GHz CPU 1
Not a very powerful box, and a bit dated, but I have seen significantly
better performance on far lesser systems.
So I am not really thinking the issue is with the hardware.
It's been slow since it was installed.
If I view the trends column, I can see the CPU load jump from below 1 to
over 10 at times.
Running prstat or top in another window while viewing the trends column,
the process ranking by CPU gets dominated by showgraph.cgi, owned by the
web server user.
Top under normal conditions.
CPU states: 99.9% idle, 0.0% user, 0.1% kernel, 0.0% iowait, 0.0%
swap
Top rendering the trends column.
CPU states: 0.0% idle, 93.8% user, 6.2% kernel, 0.0% iowait, 0.0% swap
Also getting this error
(128)Network is unreachable: connect to listener on [::]:443
in my Apache error.log file, repeated every second while rendering the
graphs.
And from time to time, I get this one.
File does not exist: /opt/csw/apache2/share/htdocs/server-status
Anybody seen anything like this?
Perhaps know of somewhere I can look for more info?
I have looked at this
http://lists.xymon.com/archive/2014-January/038780.html
But it doesn't seem relevant. Only 2 errant files, and deleting them
made absolutely no difference.
Other info that may be important....
