Abstract: A method is disclosed. The method comprises analyzing, using a processing apparatus, event log entries of a plurality of devices, the plurality of devices forming part of a group of devices sharing a common attribute, wherein event log entries of a device relate to events that have taken place during a first period of interest in respect of that device. The method also comprises determining, using the processing apparatus, for a given device in the group of devices, based on the analysis of event log entries, a predicted entry that is expected to appear in the event log of the given device during the first period of interest. An apparatus and a machine-readable medium are also disclosed.

Abstract: An example computing device includes a memory accessible at startup of the computing device, a buffer, and a set of instructions. The memory stores a configuration setting that is configurable by the application of a change request. The memory also stores a first public key and a second public key. The buffer stores change requests submitted by a remote entity, including a first change request to make a first setting change and a second change request to make a second setting change. The first change request is signed by a first private key corresponding to the first public key, and the second change request is signed by a second private key corresponding to the second public key. The set of instructions retrieves a change request from the buffer, determines whether the change request is authenticated by a public key, and if authenticated, applies the change request.

Abstract: In an example, a method includes analysing data collected from a service. A value representative of the number of anomalies in the data is generated, this value then being compared with a threshold. Depending on whether the value is greater or less than the threshold, a performance parameter of the monitoring service may be evaluated.

Abstract: In an example, there is provided a method for tracking domain name server (DNS) requests, wherein the method comprises determining whether a DNS request has resolved; and for each non-resolving DNS request decomposing the domain name of the request into multiple components, determining, for each component, a value of a metric representing the occurrence of the component in a corpus, generating a scaling factor for the request on the basis of the values for each component, and incrementing a count of the total number of non-resolving DNS requests by a scaled value on the basis of the scaling factor.

Abstract: An apparatus and method is described comprising: classifying service ticket data relating to a service request into a service topic, wherein the service ticket data is obtained from the service request relating to a device; determining, for the service request, an extent to which the service topic matches a telemetry data class, wherein the telemetry data class relates to activities at the device; and providing an output according to said determination.

Abstract: In an example, a computing device is described. The computing device comprises a communication interface and a processor. The processor is to determine whether a signature, produced by a signer, is derived from a free state under a stateful signature scheme. The free state is a state that has not been used as an input to generate a signing key. The signature is encrypted by the signer. The processor is further to, in response to determining that the signature is derived from a free state, decrypt the encrypted signature. The processor is further to transmit the decrypted signature to a recipient via the communication interface.

Abstract: In an example, an apparatus is described. The apparatus comprises a processor to interface with a computing system and a memory device comprising a set of logical cells. A logical cell of the set of logical cells indicates a data value by an amount of charge stored in a physical cell of the logical cell. Charge leakage between the physical cell and an adjacent physical cell of the logical cell is to occur at a rate that at least partially depends on a relative amount of charge stored in the physical cell and the adjacent physical cell. The apparatus further comprises a machine-readable medium storing instructions readable and executable by the processor to cause the processor to process a request issued via the computing system for the processor to cause a memory operation to be performed in the memory device.

Abstract: In an example, an apparatus is described. The apparatus comprises a memory device comprising a set of logical cells. A logical cell of the set of logical cells indicates a data value by an amount of charge stored in a physical cell of the logical cell. Charge leakage between the physical cell and an adjacent physical cell of the logical cell is to occur at a rate that at least partially depends on a relative amount of charge stored in the physical cell and the adjacent physical cell. A set of data values indicated by the set of logical cells is to change over time due to the charge leakage. The set of data values indicated by the set of logical cells is representative of information that is valid over an estimated period of time, which is based on the rate of charge leakage.
