RTView Monitor

The RTView Monitor enables you to monitor the performance, memory allocation, and utilization for all licensed RTView Data Servers, Display Servers, Historian applications, and Tomcat applications in your system. Use the RTView Monitor to determine how an RTView application is utilizing its memory.

The RTView Monitor is a demo application (located in the RTView demos/rtvmonitor directory) that you can customize for your own system, including adding alerts. To start the RTView Monitor demo, see “Starting the RTView Monitor”. To customize the RTView Monitor, see “Configuring the RTView Monitor”.

The RTView Monitor uses the RTView JMX Data Adapter to display all connectivity information available via JMX, as well as all detailed operational and management features currently available via JMX.

Monitoring Tips:

§ If your RTView system is unexpectedly slow, use the RTView Monitor to see how much memory is allocated and determine how it is being utilized. If the amount of memory used is close to the amount designated, consider making more memory available for the application.

§ When viewing metrics for application usage of JVM heap and non-heap memory, note that heap usage might go up and down between garbage collection intervals but, overall, the heap size should be stable. See “Using RTView Monitor” for more information. An exception to this is an RTView server that runs the RTVIew cache data source. In that case, heap usage grows until each cache history table reaches its maximum row counts or timeSpan. See “Caches” for more information.

§ Obtain performance metrics for both before and after a failure.

§ If an RTView application is not performing as expected, investigate the following most critical and commonly encountered issues:

Display Server: Check CPU usage. This is the most typical issue for the Display Server as the application processes many user requests.

Data Server and Historian: Check both the amount of available memory and memory used. The amount of memory used grows as these applications run, so the amount of memory originally designated might no longer be adequate. If the amount of memory used is close to the amount designated, consider making more memory available.

Configuring the RTView Monitor

This section provides step-by-step instructions on how to setup your servers to be monitored by the RTView Monitor.

Basic Steps To Configure the RTView Monitor

Perform the following steps in the order given to configure the RTView Monitor. Steps 2 and 3 are optional.

1. Setup your servers. Configure your servers to be monitored by the RTView Monitor, and to expose their metrics through JMX. See “Setup your servers for RTView Monitor” for more information.

2. Configure Application Groups (optionally). Application groups allow you to organize your application servers into categories for ease of access. You can create a group name and assign one or more servers to that group. Application servers can belong to multiple groups. See “Configure Application Groups for the RTView Monitor” for more information.

3. “Modify the default settings for the RTView Monitor” (optionally). You can edit default settings, such as the update period, in the OPTIONS.ini file.

4. Start the RTView Monitor. See “Starting the RTView Monitor” for information.

5. Verify your setup. See “Verifying Your Setup” for information.

Setup your servers for RTView Monitor

1. To set up your RTView servers for monitoring, execute run_configutil.bat, located in the /bin directory. The Application Options dialog opens.

2. Select JMX from the list of options in the left pane.

3. Select the JMX Connections tab, then click Add Connection to open the Add JMX Connection dialog.

4. In the Add JMX Connection dialog, make the following entries:

Connection Name: Enter the connection name as you want it to appear in the RTView Monitor.

Host or IP: Enter the server host or IP address.

Port: Enter the JMX port number assigned to that server.

Note: Use the additional fields only if needed for your specific configuration.

The settings entered in the Add JMX Connection dialog are stored in the local JMXOPTIONS.ini file, located in the demos/rtvmonitor directory (the JMXOPTIONS.ini resides in the same directory as the RTView Monitor application).

You can also use a text editor to edit the JMXOPTIONS.ini file, using the following syntax:

jmxconn <servername> <IPaddress> <port> URL:- - - 'false'

Where:

<servername> is a name of your choosing for the application.

<IPaddress> is the IP address of the host on which the application runs.

<port> is the port number of the host on which the application runs. The port number must be the same port number used when launching the respective server.

URL:- - - 'false'

For example:

jmxconn MyDataserver localhost 9952 URL:- - - ‘false’

jmxconn MyDisplayServer localhost 9953 URL: - - - ‘false’

jmxconn slhost1_OCM_HISTORIAN 192.168.200.101 9913 URL:- - - ‘false’

5. Click OK when you are finished.

6. To configure your servers to expose their metrics through JMX, add the following parameter to the command line string of each server:

-jmxport:xxxxx

Where xxxxx is the same JMX port number used to configure the “RTView Monitor”.

Note: SL recommends port numbers above 10000 to avoid conflicts with existing SL server application port numbers.

To (optionally) configure Application Groups for the RTView Monitor, continue to the next steps (below). To (optionally) modify the RTView Monitor default settings, see “Modify the default settings for the RTView Monitor”. Otherwise, proceed to “Starting the RTView Monitor”.

Configure Application Groups for the RTView Monitor

1. Edit the appgroups.xml file, located in the demos/rtvmonitor directory, using the following format:

<tr>

<td>ApplicationGroupName</td>

<td>NameOfAnApplication</td>

</tr>

Where each row (<tr>) contains two columns (<td>). The first column contains the name of the Application Group, and the second column contains the name of an application to be contained in that group.

Application groups allow you to organize your application servers into categories for ease of access. You can assign one or more servers to a group. Application servers can belong to multiple groups.

In the following example, an Application Group named DataServers contains two applications, slhost1_OCM_DATASERVER and slhost3_OCM_DATASERVER:

<?xml version="1.0"?>

<tc name="GROUPNAME"

type="string"

index="true"/>

<tc name="APPNAME"

type="string"

index="false"/>

<tr>

<td>DataServers</td>

<td>slhost1_OCM_DATASERVER</td>

</tr>

<tr>

<td>DataServers</td>

<td>slhost3_OCM_DATASERVER</td>

</tr>

</table>

</dataset>

The XML code preceding the first <tr> and following the last </tr> must not be altered.

To (optionally) modify the RTView Monitor default settings, see “Modify the default settings for the RTView Monitor,” next. Otherwise, proceed to “Starting the RTView Monitor”.

Modify the default settings for the RTView Monitor

Optionally, you can edit the default performance settings for the RTView Monitor, such as the update period, in the OPTIONS.ini file. The OPTIONS.ini file settings override settings made in the Application Options dialog.

Proceed to “Starting the RTView Monitor,” next.

Starting the RTView Monitor

This section provides step-by-step instructions on how to start the RTView Monitor in the “Display Viewer” and the “Thin Client”.

Display Viewer

To start the RTView Monitor:
