<font size=2 face="sans-serif">Hello,</font>
<br>
<br><font size=2 face="sans-serif">Could it comes from how the xymonproxy
program handles the MACHINE variable ?</font>
<br>
<br><font size=2 face="sans-serif">I say that because when the process
becomes nuts, he makes only 'gettimer' action. Then I have a look in the
source file and found this line (line 452) that could correspond:</font>
<br>
<br><font size=2 face="sans-serif"><i>if (proxyname && ((now =
gettimer()) >= (laststatus+300))) {</i></font>
<br>
<br>
<br><font size=2 face="sans-serif">proxyname comes from $MACHINE</font>
<br>

I managed to reproduce the issue:</font><font size=3> </font><font size=2 face="sans-serif"><br>
- I start the XYMON as a proxy server => Non pbl</font><font size=3>
</font><font size=2 face="sans-serif"><br>
- Stop the XYMON
=>
Process remains alive (xymonlaunch)</font><font size=3> </font><font size=2 face="sans-serif"><br>
- Kill the xymonlaunch</font><font size=3> </font><font size=2 face="sans-serif"><br>
- Start the XYMON as aproxy server => The pbl occurs again </font><font size=3><br>
</font><font size=2 face="sans-serif"><br>
Could some files in the ./tmp of XYMON influence this ?</font><font size=3>

<p><font size=2>Last Sunday, I wanted to start a xymonproxy (vers 4.3.12)
on a Solaris 10.5 with 900 targets . I had a performance issue:</font><font size=3>
</font><font size=2><br>
- The xymonproxy process used 100% of only one CPU (no multithread seen).</font><font size=3>
</font><font size=2><br>
- On the main XYMON server, data from this proxy (I have one other on Ubuntu
with 50 targets working fine) came with difficulties (delays and lacks).</font><font size=3>
</font><font size=2><br>
<br>
I tried to used the -lqueue option for the proxy with no success.</font><font size=3>
</font><font size=2><br>
Nothing special seen in any logs.</font><font size=3> </font><font size=2><br>
The UNIX admin said me that the xymonproxy was just making 'time()' command
all the time.</font><font size=3> </font>
<p><font size=3>I've had the proxy handling about 5000 hosts simultaneously.
On Linux, though. </font>
<p><font size=3>I have not heard of such behaviour before, and I am sure
there must be others running the proxy on Solaris in a similar setup. If
you can make it happen again, please do a "kill -USR2" on the
xymonproxy process to toggle debugging on/off. </font>
<p><font size=3>None of the Xymon tools are multithreaded - so far I have
stuck to the traditional Unix way of doing things. </font>
