An automatic service monitor in an information-technology environment performs regular search queries against generated machine data to derive performance measurements. The information technology environment is defined in terms of services provided by entities, and the performance measurements are defined as key performance indicators (KPIs) of the services. Generated machine data used by the search queries pertain to the entities performing the service. Definitional information for the services, entities, and KPIs is administered by a user to control the operation of the service monitor. Various aspects of such definitional information as well as related performance measurement information may be presented in a unified console display tailored to, and organized around, a particular service. The console display may serve as a central launch point by supporting user interaction to navigate to other specialized monitoring interfaces.

Techniques are presented in which a new information element signaling priority of a management entity is included in a setup (e.g., S1-Setup) response or configuration update message sent by a management entity to a base station entity. The base station entity interprets this priority information along with the relative capacity information in an appropriate way to load-distribute the traffic/calls to highly preferable management entity instances (at a local site) when they are available, and switchover/failover to lower preference management entity instances (at a remote site) when there is a local site outage/failure or insufficient capacity in a geo-resilient pooled network.

A method and associated systems of automatic notification of isolation of a first networked device. In response to detecting that it is not being properly managed by a network-management means, the first networked device creates a notification message that identifies the problem and requests proper network management. The device then transmits this message to any other device or networked node that it can communicate with, along with a request that recipients try to forward the message to the network-management means. If a device that receives the message is able to forward the message successfully, the network-management means takes appropriate steps to begin properly managing the first networked device.

One or more virtual supervisory control and data acquisition (SCADA) controllers are provided. The virtual SCADA controller(s) may be deployed upon a detection of a failure of a physical SCADA controller. An on-site module may detect failure including a security breach which causes the physical SCADA controller to be disconnected from a network and the virtual SCADA controller(s) to take over control. The virtual SCADA controller(s) may be on-site or off-site.

A device may receive, from a load balancing device, configuration information that identifies a set of nodes for which a status is to be determined. The device may generate a data structure. The data structure may store information that identifies a status of the set of nodes. The device may transmit a status request to one or more nodes. The device may determine the status of the one or more nodes based on transmitting the status request. The device may update the data structure based on determining a change in status of the one or more nodes. The device may provide, to the load balancing device, information that identifies the change in status of the one or more nodes based on updating the data structure.

Systems and methods for monitoring failures of network devices and identifying potential sources of the failures by a device health monitor are provided. A device monitor receives a usage log of a network device over a network connection and analyzes an abnormal usage of the network device from the usage log. The device health monitor further retrieves environment information of the network device and analyzes a defect of the environment information of the network device by associating the abnormal usage with the environment information. The device health monitor sends a message regarding the defect of the environment information to an administrator of the network device.

Methods and apparatus for highly available rack management in Rack Scale environment. Rack Management Modules (RMMs) are configured to manage power and thermal zones in a rack including a plurality of pooled system drawers, wherein each pooled system drawer is associated with a respective power zone including power sensors and power control devices and a respective thermal zone including thermal sensors and thermal devices. During operation, one of the RMMs is implemented as a master RMM, and the other is implemented as a slave RMM. The master RMM is used to monitor the power and thermal zones. State information is periodically synchronized between the master RMM and the slave RMM. The RMMs are further configured to perform a fail-over operation in connection with a failed or failing RMM, where after the fail-over operation the slave becomes the new master RMM and the previous master RMM becomes the new slave.

The present invention provides a method for receiving information, a method for sending information, and apparatuses for the same. The method for receiving information includes: when a control plane apparatus is capable of managing a forwarding plane apparatus, receiving, by the forwarding plane apparatus, information used for packet forwarding path calculation sent by the control plane apparatus, where the forwarding plane apparatus and the control plane apparatus are located in a network with a network architecture featuring forwarding and control element separation. According to the technical solutions provided in embodiments of the present invention, the forwarding plane apparatus does not need to actively obtain the information used for packet forwarding path calculation before calculating a packet forwarding path based on the information used for packet forwarding path calculation.

A method and system for automatic redirection of control channel messages in response to a control channel failure with a target switch in a software defined networking (SDN) network, the automatic redirection occurring before a topology of the SDN network is updated in response to the control channel failure. The method includes determining whether a control channel message is to be sent to an SDN controller, checking availability of the control channel, selecting a backup port to reach the SDN controller in response to the control channel being unavailable, and forwarding the control channel message to the SDN controller via the backup port.
