Abstract

Techniques are described for centrally directed self-healing of networked devices. Large numbers of networked devices can be configured according to configuration data. A central management system (CMS) can group the devices into device swarms having identical nominal device configurations. The CMS can determine a swarm-agreed configuration state for each device swarm that corresponds to a determined “correct” configuration for devices in the device swarm. Over time, the devices send configuration fingerprints to the CMS to indicate their current configuration states, and the CMS can analyze the current configuration states against the swarm-agreed configurations to detect potential configuration issues. In response, the CMS can automatically direct remedying of the detected configuration issues in accordance with the swarm-agreed configurations.

Dependent claims

A centralized monitoring system (CMS) for self-healing of networked devices, the CMS comprising:

a device interface subsystem to communicatively couple with a plurality of networked devices via one or more communication networks, the device interface subsystem configured to receive a particular configuration fingerprint by a centralized monitoring system (CMS) from a particular networked device of the plurality of networked devices, the particular configuration fingerprint indicating a particular current configuration state for the particular networked device, the particular networked device associated with a particular nominal device configuration;
a swarm data store having, stored thereon in association with each of a plurality of device swarms, a respective population of the networked devices determined to have a same respective nominal device configuration associated with the device swarm, and a respective swarm-agreed configuration determined to be a correct configuration state for the same respective nominal device configuration associated with the device swarm;
a swarm analyzer configured to:
associate the particular configuration fingerprint with a particular device swarm of the plurality of device swarms according to matching the particular nominal device configuration to the respective nominal device configuration for the particular device swarm;
and
detect a device configuration issue by detecting a discrepancy between the particular current configuration state of the particular networked device and a particular swarm-agreed configuration being the respective swarm-agreed configuration associated with the particular device swarm;
and
a self-healing subsystem configured, responsive to the detecting the device configuration issue, to direct self-healing of the particular networked device in accordance with applying the particular swarm-agreed configuration.

detecting, by the CMS, a device configuration issue by detecting a discrepancy between the particular current configuration state of the particular networked device and the particular swarm-agreed configuration associated with the particular nominal device configuration, the swarm-agreed configuration generated by determining, for each device swarm, a respective swarm-agreed configuration associated with the same respective nominal device configuration for the particular device swarm, the particular swarm-agreed configuration being the respective swarm-agreed configuration determined for the particular device swarm;
and
directing, by the CMS responsive to the detecting the device configuration issue, self-healing of the particular networked device in accordance with applying the particular swarm-agreed configuration.
