Step 3 In the Health column, the switch health is calculated by the capacity manager based on the following formula in the server.properties file.

The function to implement is

# calculate(x, x1, y, y1, z)

# @param x : Total number of modules

# @param x1: Total number of modules in warning

# @param y: Total number of switch ports

# @param y1: Total number of switch ports in warning

# @param z: Total number of events with severity of warning or above

Step 4 The value in the Health column is calculated based on the following default equation.

((x-x1)*1.0/x) *0.4 + ((y-y1)*1.0/y)*0.3 + ((z*1.0/1000>=1) ? 0: ((1000-z)*1.0/1000)*0.3).

In the above formula, the switch health value is calculated based on the following:

    • Percentage of Warning Modules (Contributes 40% of the total health).
    • Percentage of Warning Ports (Contributes 30% of the total health)
    • Percentage of events with severity of Warning or above (Contributes 30% of the total health. If there are more than 1000 warning events, the event health value is 0).

You may also have your own health calculation formula by implementing the common interface class:com.cisco.dcbu.sm.common.rif.HealthCalculatorRif. Add the.jar file to the DCNM server and modify the health.calculator property to point to the class name you have created.

Configuring the RRD Database

Configuring the Round Robin Database (RRD) allows you to set the intervals at which data samples are collected. After applying the configuration, the database storage format is converted to a new format at those intervals. Because database formats are incompatible with each other, you must copy the old data (before the conversion) to the $INSTALLDIR/pm directory. See the "Importing the RRD Statistics Index" topic.


Step 1 From the menu bar, choose Admin > Performance > Databases.

You see the Performance Database (collection interval) page.

Step 2 In the top row of the Days column, enter the number of days to collect samples at 5-minute intervals.

Step 6 Click Apply to apply your changes, or click Defaults to reset the file sizes to the default values.

If you are applying new values, or if the current values are not the default values, you see a message indicating that the conversion of the RRD files take a certain amount of time and that the database is unavailable until then. The time it takes depends on the difference between the old and new values.


Note The system allows you to convert data, one process at a time. When you start converting the data, the Apply and Default buttons change to Refresh and Cancel so that another process cannot be inadvertently started. The display is the same for all browsers that access the server during this time. Click Refresh to view the latest progress. Click Cancel to cancel the process of converting the data. If the job is successfully canceled, you see the Apply and Default buttons again. If the cancel job is not successful, you see a message indicating that the cancellation has failed.


If you want to perform this procedure, perform it before collecting a lot of data because data conversion can take a long time.

Using Cisco DCNM Web Client with SSL

By default, Cisco DCNM Web Client uses HTTP. If you want to install SSL certificates and use Cisco DCNM Web Client over HTTPS (using TCP port 443 or another custom port), you need a certificate for each external IP address that accepts secure connections. You can purchase these certificates from a well-known Certificate Authority (CA).

To enable SSL, you must set up the keystore to use either a self-signed certificate or a certificate from a trusted third-party company such as VeriSign.

This section includes the following topics:

Creating a Local Certificate


Step 1 Set up a keystore to use a self-signed certificate (local certificate). From the command line, enter the following command on windows:

%JAVA_HOME%/bin/keytool -genkey -alias tomcat -keyalg RSA -keystore "C:\Program Files\Cisco Systems\dcm\jboss-4.2.2.GA\server\fm\conf\fmserver.jks"
 

Step 2 Enter your name, organization, state, and country. Enter change it when prompted for a keystore password. If you prefer to use your own password, do not forget to change the keystorepass attribute in the server.xml file. When prompted for a key password, press Enter or use the same password as the keystore password.


Note You can now follow the steps in the next section for modifying DCNM Web Client to use SSL.


To obtain a certificate from the Certificate Authority of your choice, you must create a Certificate Signing Request (CSR). The CSR is used by the certificate authority to create a certificate that identifies your website as secure.

Creating a Certificate Request


Step 1 Create a local certificate (as described in the previous section).


Note You must enter the domain of your website in the fields First and Last name in order to create a working certificate.


Step 2 Create the CSR with this commandon windows:

keytool -certreq -keyalg RSA -alias tomcat -file certreq.csr -keystore " C:\Program Files\Cisco Systems\dcm\jboss-4.2.2.GA\server\fm\conf\fmserver.jks"
 

Now you have a file called certreq.csr. The file is encoded in PEM format. You can submit it to the certificate authority. You can find instructions for submitting the file on the Certificate Authority website.

Step 3 After you have your certificate, you can import it into your local keystore. You must first import a Chain Certificate or Root Certificate into your keystore. You can then import your certificate.

Step 4 Download a Chain Certificate from the Certificate Authority where you obtained the certificate:

    • For Verisign.com commercial certificates, go to this URL:

  • For Verisign.com trial certificates, go to this URL:

http://www.verisign.com/support/verisign-intermediate-ca/Trial_Secure_Server_Root/index.html

 
    • For Trustcenter.de, go to this URL:

http://www.trustcenter.de/certservices/cacerts/en/en.htm#server

 
    • For Thawte.com, go to this URL:

http://www.thawte.com/certs/trustmap.html

 
    • Import the Chain Certificate into your keystore by entering the keytool -import -alias root -keystore " C:\Program Files\Cisco Systems\dcm\jboss-4.2.2.GA\server\fm\conf\fmserver.jks" -trustcacerts -file filename_of_the_chain_certificate command.
    • Import the new certificate in X509 format by entering the keytool -import -alias tomcat -keystore " C:\Program Files\Cisco Systems\dcm\jboss-4.2.2.GA\server\fm\conf\fmserver.jks" -trustcacerts -file your_certificate_filename command.

Modifying Cisco DCNM Web Client to Use SSL


Step 1 Stop Cisco DCNM Web Client if you have already launched it. If you have installed the Cisco DCNM Web Client on Windows, you can stop the service using Windows Services under Administrative Tools.

Step 2 Use a text editor to open \jboss-4.2.2.GA\server\fm\deploy\jboss-web.deployer\server.xml from the directory where DCNM Web Client is installed. You see the following lines in the beginning after some copyright information:

<Connector className="org.apache.catalina.connector.http.HttpConnector"
port="80" minProcessors="5" maxProcessors="75"
enableLookups="false" redirectPort="8443"
acceptCount="10" debug="0" connectionTimeout="60000"/>
<!-- Define an SSL HTTP/1.1 Connector on port 8443 -->
<!--
<Connector className="org.apache.catalina.connector.http.HttpConnector"
port="8443" minProcessors="5" maxProcessors="75"
enableLookups="true"
acceptCount="10" debug="0" scheme="https" secure="true">
<Factory className="org.apache.catalina.net.SSLServerSocketFactory"
clientAuth="false" protocol="TLS"/>
</Connector>
-->
 

Step 3 Comment the first <Connector> element and uncomment the second one. Note that the port changes from 8443 to 443 and keystore and keypass are added. Your file should look like the following example:

<!-- A HTTP/1.1 Connector on port 8080
<Connector port="80"
maxThreads="250" protocol="HTTP/1.1" strategy="ms" maxHttpHeaderSize="8192"
emptySessionPath="true"
server="Apache"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" allowTrace="false"/>
 
-->
 
<!-- Add this option to the connector to avoid problems with
.NET clients that don't implement HTTP/1.1 correctly
restrictedUserAgents="^.*MS Web Services Client Protocol 1.1.4322.*$"
-->
<!-- A AJP 1.3 Connector on port 9009 -->
<Connector port="9009"
emptySessionPath="true" enableLookups="false" redirectPort="8443"
protocol="AJP/1.3"/>
 
<!-- SSL/TLS Connector configuration using the admin devl guide keystore -->
<Connector port="443"
protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="100" strategy="ms" maxHttpHeaderSize="8192"
emptySessionPath="true"
server="Apache"
scheme="https" secure="true" clientAuth="false" sslProtocol = "TLS"
securityDomain="java:/jaas/encrypt-keystore-password"
SSLImplementation="org.jboss.net.ssl.JBossImplementation" allowTrace="false"/>
 

Step 4 Save this file.

Step 5 Create a keyword password from the command line by navigating to C:\Program Files\Cisco Systems\dcm\fm\bin, entering Encrypter.bat ssl, and then entering changeit as the password.

Step 6 Restart Cisco DCNM Web Client .


Note If you restart Cisco DCNM-SAN Server with SSL enabled, you must restart Cisco DCNM Web Client. If you want to stop and restart Cisco DCNM-SAN Server with SSL disabled, you must restart Cisco DCNM Web Client.
