Monitoring Within the Resource Pool

The N1 Provisioning Server is responsible for monitoring its assigned farms as directed by the configuration stored in the CPDB. The N1 Provisioning Server is also the control gateway for some system configuration and control commands, such as configuring additional network interfaces. The monitoring software running on the N1 Provisioning Server forwards monitoring messages to the CPDB.

Monitoring Resource Pool Servers

N1 Provisioning Server agents are deployed on resource pool servers during installation and configuration. The agent software collects various monitoring data from the resource pool server and sends it to the N1 Provisioning Server.

The N1 Provisioning Server processes monitoring data and stores it in the message repository in the CPDB. The CPDB has a local database for messages processed by the servers. You also can route messages to an external application, such as a Network Monitoring System (NMS).

The monitoring system includes the TSPRagsol agent package for the Solaris 8 operating environment and the TSPRaglinx agent for the RedHat AS2.1 operating environment.

For resource pool servers assigned to farms, the system can monitor the following events:

• Availability of the primary Ethernet interface (ICMP ECHO or ping)

• CPU utilization

• Disk utilization

• RAM utilization

• Swap memory allocation

Refer to Chapter 4, Building, Updating, and Monitoring Server Farms, of the N1 Provisioning Server 3.1, Blades Edition, Control Center Management Guide for additional monitoring configuration information.

Stopping the Resource Pool Server Monitoring Process

If you need to reboot a resource pool server that is active in a farm, stop the monitoring process. Rebooting is often required after adding applications or other software packages to a server. To stop the monitoring process use the /opt/terraspring/sbin/tsprmonitor command to stop the monitoring process. Doing so prevents replaceFailedDevice requests from occurring. The time during which the resource pool server should not be available is configurable. See the tsprmonitor man page for details.

Monitoring Within the Fabric Layer

The monitoring manager on the CPDB monitors the health and performance of devices in the fabric layer, such as Ethernet switches. The monitoring manager logs the information according to the logging configuration.
