Chapter 19. Managing the Cloud

Each SNMP trap contains the following information: message, podId, dataCenterId, clusterId, and generationTime.

19.4.2.2. Syslog Alert Details

CloudPlatform generates a syslog message for every alert. Each syslog message incudes the fields alertType, message, podId, dataCenterId, and clusterId, in the following format. If any field does not have a valid value, it will not be included.

Date severity_level Management_Server_IP_Address/Name alertType:: value dataCenterId:: value podId:: value clusterId:: value message:: value

For example:

Mar 4 10:13:47

WARN

localhost

alertType:: managementNode message:: Management

server node 127.0.0.1 is up

 

 

 

 

 

19.4.2.3. Configuring SNMP and Syslog Managers

To configure one or more SNMP managers or Syslog managers to receive alerts from CloudPlatform:

1.For an SNMP manager, install the CloudPlatform MIB file on your SNMP manager system. This maps the SNMP OIDs to trap types that can be more easily read by users. The file must be publicly available. For more information on how to install this file, consult the documentation provided with the SNMP manager.

2.Edit the file /etc/cloudstack/management/log4j-cloud.xml.

#vi /etc/cloudstack/management/log4j-cloud.xml

3.Add an entry using the syntax shown below. Follow the appropriate example depending on whether you are adding an SNMP manager or a Syslog manager. To specify multiple external managers, separate the IP addresses and other configuration values with commas (,).

Note

The recommended maximum number of SNMP or Syslog managers is 20 for each.

The following example shows how to configure two SNMP managers at IP addresses 10.1.1.1 and 10.1.1.2. Substitute your own IP addresses, ports, and communities. Do not change the other values (name, threshold, class, and layout values).

<appender name="SNMP" class="org.apache.cloudstack.alert.snmp.SnmpTrapAppender"> <param name="Threshold" value="WARN"/> <!-- Do not edit. The alert feature assumes WARN. -->

<param name="SnmpManagerIpAddresses" value="10.1.1.1,10.1.1.2"/> <param name="SnmpManagerPorts" value="162,162"/>

<param name="SnmpManagerCommunities" value="public,public"/>

<layout class="org.apache.cloudstack.alert.snmp.SnmpEnhancedPatternLayout"> <!-- Do not edit -->

<param name="PairDelimeter" value="//"/> <param name="KeyValueDelimeter" value="::"/>

</layout>

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
