|

|
|
<div><p>With the quality of service (QoS) monitor, you can
|
||
|
|
verify that the QoS policies are working as you intend them to work.</p>
|
||
|
|
<p>The QoS monitor can help you in the planning phase and the troubleshooting
|
||
|
|
phase of QoS.</p>
|
||
|
|
<p>You can use the monitor to analyze your IP traffic through the server.
|
||
|
|
This helps you determine where congestion is occurring within your network.
|
||
|
|
The QoS monitor can help you continue to monitor your network so you can adjust
|
||
|
|
your policies as needed.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Planning and maintaining performance</h4><p>One of the
|
||
|
|
most difficult parts of implementing QoS is determining what performance limits
|
||
|
|
to set in your policies. There is no specific recommendation because every
|
||
|
|
network is different. To help you determine what values are right for you,
|
||
|
|
you might want to use the monitor before you even start any business-specific
|
||
|
|
policies.</p>
|
||
|
|
<p>Try to create a differentiated service policy without selecting
|
||
|
|
metering to identify how your current network traffic is behaving. Enable
|
||
|
|
this policy and start the monitor. The monitor's results can help you tune
|
||
|
|
your policies to your specific needs. See a sample monitor policy that will
|
||
|
|
identify how your current traffic is behaving.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Troubleshooting performance problems</h4><p>You can also
|
||
|
|
use the monitor to troubleshoot problems. Using the monitor output, you can
|
||
|
|
determine if the parameters you assigned to a policy are being followed. If
|
||
|
|
your policies are appearing in the monitor but do not appear to be affecting
|
||
|
|
traffic, do the following verification:</p>
|
||
|
|
<ul><li>If the policy is filtering based on a Uniform Resource Identifier (URI),
|
||
|
|
verify that Fast Response Cache Accelerator (FRCA) is enabled and configured
|
||
|
|
properly. Before you set up an inbound policy that uses URIs, you must ensure
|
||
|
|
that the application port assigned for the URI matches the listen directive
|
||
|
|
enabled for FRCA in the Apache Web server configuration.</li>
|
||
|
|
<li>Verify that the policy schedule. You might be looking for results during
|
||
|
|
an inactive time.</li>
|
||
|
|
<li>Verify that the port number is correct.</li>
|
||
|
|
<li>Verify that the IP address is correct.</li>
|
||
|
|
</ul>
|
||
|
|
<p>For some examples of monitor output, visit the QoS scenarios or view
|
||
|
|
all the monitor fields in monitoring.</p>
