<p class="MsoPlainText">Hello all,<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I am a new poster to the nagios mailing list; however, I
have used nagios for a number of years now.<span style="">
</span>I am having an issue where the status and extinfo CGIs stop updating. <o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText"><span style=""></span>Our west coast nagios
setup consists of one physical master server, and one physical slave
server.<span style=""> </span>The slave server runs 5 nagios
instances, each with approximately 500 - 1000 service checks.<span style=""> </span>All total, we have 3400 service checks being
accepted by the master.<span style=""> </span>We are currently
running nagios 3.0.1.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">The os/arch/type is CentOS5, x86_64, and each server has
8 intel cores and 16GB of RAM.<span style=""> </span>We were
experiencing extremely high latency in our service checks (thousands and
thousands and thousands of seconds) and realized that this was primarily due to
the serial nature of nsca.<span style=""> </span>Sending each service
check result individually back to the master would take seconds each, and the slave
check queues would back up behind that process.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">We did a little poking around and installed the ocsp
sweeper from nagios exchange, which immediately cured our performance issues.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Now, however, we experience very strange behavior:<span style=""> </span>some handful of hours after each nagios
restart, the webUI CGIs will stop displaying accurate performance information (services
passively checked for 1 min - 1 hr report 0, and only the 'since program start'
reports a number) and - more troubling - the status CGI does not update.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Has anyone experienced this issue before?<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Thanks.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
