<p class="MsoNormal"><span style="color:#1F497D">This really was an easy hack, and I think I just have overseen this possibility to change the variable at exactly this position. But this could be due to the fact that I’m not 100% in PERL and then you cannot

<p class="MsoNormal"><span style="">Christian, </span></p>
<div>
<p class="MsoNormal">Hello out there,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Perhaps there’s anybody else using alerts:html_mail1.2 which is available from
<a href="http://xymonton.org/alerts:html_mail1.2"><span style="color:windowtext; text-decoration:none">http://xymonton.org/alerts:html_mail1.2</span></a></p>
<p class="MsoNormal"> </p>
</div>
<p class="MsoNormal"><span style="font-size:12.0pt; font-family:"Times New Roman","serif"">I do! I wrote the latest version, some updates still pending.<br style="">
<br style="">
</span></p>
<div>
<p class="MsoNormal">I’ve set it up and <span class="spelle">i’ve</span> done some changes to the way it sends the subject and the body. All of this is working fine.</p>
<p class="MsoNormal">There’s one thing that makes me wonder and I’ve tried a bit for me, but I’m concerned why I cannot get this to work.</p>
<p class="MsoNormal">The body of the <span class="spelle">eMails</span> coming from the
<span class="spelle">perl</span> script contains a link to the affected host, for example:</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><a href="http://XYMONHOST/xymon-cgi/bb-hostsvc.sh?HOST=testhost&SERVICE=http"><span style="color:windowtext; text-decoration:none">http://XYMONHOST/xymon-cgi/bb-hostsvc.sh?HOST=testhost&SERVICE=http</span></a></p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">But I need to have the link as follows:</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"><a href="http://XYMONHOST.FULL-QUALIFIED-DOMAIN/xymon-cgi/bb-hostsvc.sh?HOST=testhost&SERVICE=http"><span style="color:windowtext; text-decoration:none">http://XYMONHOST.FULL-QUALIFIED-DOMAIN/xymon-cgi/bb-hostsvc.sh?HOST=testhost&SERVICE=http</span></a></p>
<p class="MsoNormal"> </p>
</div>
<p class="MsoNormal"><span style="font-size:12.0pt; font-family:"Times New Roman","serif"">If you look at the perl code, these URLs are constructed using exactly what xymon has as in its config files.<br style="">
<br style="">
</span></p>
<div>
<p class="MsoNormal"> </p>
<p class="MsoNormal">This is due to the fact that we do monitoring for different customers having their
<span class="spelle">Xymon</span> servers with different domain names.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">For example, we have a <span class="spelle">Xymon</span> server xymonA.domainA.org and another one called xymonB.domainB.org.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Therefore I need the fully qualified hostname in the link.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">While reviewing the <span class="spelle">perl</span> code of the script I recognized a section “Retrieve the data from the environment variables”.</p>
<p class="MsoNormal">Within there I inserted a line</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">$BBSERVERHOSTNAME = $ENV{‘BBSERVERHOSTNAME’} || “”;</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">The syntax is the same as for the other variables. Then I changed the line containing the subject for the
<span class="spelle">eMail</span> to contain this variable instead of $BBSERVERWWWNAME.</p>
<p class="MsoNormal">As last step I changed the setting for the XYMONSERVERHOSTNAME (which is also set as BBSERVERHOSTNAME) in xymonserver.cfg.
</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">After restarting the <span class="spelle">xymon</span> services and the
<span class="spelle">webserver</span> I’m still getting <span class="spelle">eMails</span> containing the link WITHOUT having the fully qualified hostname.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I’m NOT getting entries in /<span class="spelle">var</span>/log/<span class="spelle">xymon</span>/alert.log saying that the variable $BBSERVERHOSTNAME is uninitialized.</p>
<p class="MsoNormal">When commenting out the line</p>
<p class="MsoNormal">$BBSERVERHOSTNAME = $ENV{‘BBSERVERHOSTNAME’} || “”;</p>
<p class="MsoNormal">in the <span class="spelle">perl</span> script, then I get this message.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">For me this means, that I might have done the most things the right way; didn’t
<span class="spelle">i</span>? Anybody out there having an idea?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Sorry if my <span class="spelle">english</span> isn’t at 100%....</p>
<p class="MsoNormal"> </p>
</div>
<p class="MsoNormal"><span style="font-size:12.0pt; font-family:"Times New Roman","serif"">The $BBSERVERWWWNAME variable is what is used for the hostname in the URL section.<br>
<br>
If you have separate servers I suggest 2 options:<br>
1) change the BBSERVERWWWNAME variable in the server.cfg file on each server<br>
2) hack the perl code to hard-code the BBSERVERWWWNAME variable on each server.<br>
<br>
The easiest way to test the script is to set up a special alert rule for a testing host/service combination in alerts.cfg - e.g.<br>
<br>
HOST=testhost SERVICE=testname<br>
SCRIPT /path/to/html_mail.pl testalias COLOR=red<br>
<br>
Then send red status updates using the xymon command - e.g. (on the xymon server)<br>
<br>
xymon localhost "status testhost.testname red html_mail test"<br>
<br>
Send a green status to reset and then repeat to trigger the script again.<br>
This should not require restarting services at all.<br>
