  • Patent number: 11611496
    Abstract: A remote server monitors the health of a network of computing devices through hierarchical composite indicators by obtaining performance attributes from computing devices in the network. The server generates a composite indicator associated with one or more of the computing device based on a combination of at least two performance attributes of the computing device(s). The server monitors the composite indicator and, responsive to a determination that the composite indicator indicates an alert condition, generates an alert associated with the computing device(s). Additionally, if the alert condition is subject to remediation, the server causes at least one of the computing devices to execute a command to provide remediation of the alert condition.

  • Publication number: 20220360513
    Abstract: Presented herein are embodiments for quickly identifying and recommending key performance indicators (KPIs) for network devices based on the type of network device and/or role of the device. The type or configuration of the network device may be obtained and compared to the capabilities of the network device. Operational or performance information of the network device, represented by strings, may be obtained based on the configuration information. Operational information that is not relevant to the configuration of the network device may be filtered out. The remaining operational information may be ranked as KPIs based on a relevance of the operational information with respect to the configuration information.

  • Patent number: 11271835
    Abstract: A remote server monitors a network of computing devices through hierarchical composite indicators by obtaining telemetry data from a computing device in a network of computing devices. The telemetry data includes performance attributes of the computing device. The server generates a composite indicator associated with the computing device based on a combination of at least two performance attributes of the computing device. The server monitors the composite indicator and, responsive to a determination that the composite indicator meets an alert threshold, generates an alert associated with the computing device. Additionally, the server can monitor the health of the network of computing devices based on composite indicators from multiple computing devices in the network.

  • Publication number: 20200358648
    Abstract: Presented herein are embodiments for performing maintenance on devices in a network. A plurality of maintenance operations are generated that are to be executed on a plurality of network devices in a network. Instructions are transmitted to the plurality of network devices to execute one or more maintenance operations of the plurality of maintenance operations. Continuous checks are performed on the execution of the one or more maintenance operations by analyzing telemetry data that is received from the plurality of network devices. In response to an indication of a network device failing a criterion of a continuous check, one or more corrective actions are automatically performed.

  • Publication number: 20140075520
    Abstract: A system and method for providing whitelist functionality for use with a cloud computing environment. In accordance with an embodiment, software applications being deployed to the cloud are restricted from using certain classes or application program interfaces (APIs). During provisioning by, e.g., a Java cloud services (JCS) infrastructure, or another component of the cloud environment, an application's resources, such as its classes or API calls, can be matched against a whitelist of acceptable resources. If the application fails to be validated against the whitelist, it will not be deployed to the cloud, and the customer/user notified accordingly. In accordance with an embodiment, a whitelist functionality can be packaged within a software development kit (SDK), which customers/users can use during development of their applications, to verify that the applications will comply with, or successfully validate against the whitelist, prior to attempting to deploy the applications to the cloud.
