HWNPM0281I Performance monitoring is unavailable for resource resource_name because an agent for monitoring the resource was not defined. For IBM Spectrum Scale, the problem might occur because the data collection service cannot connect to port 9084 on the node where the collector component of the IBM Spectrum Scale performance monitoring tool is running.

Explanation

For the product to collect performance statistics and other necessary information to monitor a resource, an agent that manages the resource must be defined. An agent can be an SMI-S provider, ZiMon agent for IBM Spectrum Scale, or a native API for a resource.

Action

Define a data source for the resource, such as an SMI-S provider, a ZiMon agent for IBM Spectrum Scale, or a resource-specific service.

Before you can collect performance data for IBM Spectrum Scale, the server that hosts the data collector must be able to connect to port 9084 on the node where the collector component of the IBM Spectrum Scale performance monitoring tool is running.

To ensure that the server that hosts the data collector can connect to the collector node, complete the following steps:
  1. Determine the node that is configured as the collector node by viewing the /opt/IBM/zimon/ZIMonSensors.cfg file on one of the sensor nodes. The collector node is set in the host property of the collectors section in this file. For example, collectors = { host = "node3" port = "4739"}
  2. Ensure that the host property is set to one of the following options:
    • An IP address that can be reached by the server that hosts the data collector
    • A host name that can be resolved to a reachable IP address by the the server that hosts the data collector
