An example software patch difference device includes a processor to: receive current software version indicators of software installed at monitored devices; generate, using a cryptographic function, respective identifiers of the current software version indicators for the monitored devices; retrieve, from storage, respective previous identifiers of previous software version indicators of the software installed at the monitored devices, the respective previous identifiers generated using the cryptographic function; compare, for the current software version indicators, a respective identifier with a respective previous identifier; when a difference is determined therebetween for a given device: replace, at the storage, respective previous software version indicators for the given device with respective current software version indicators; and transmit, to an analytics device, a respective software change indicator of the given device, to trigger the analytics device to generate a report indicating statistics for respective software versions installed at the monitored devices.

Software patch difference devices

An example polling computing device includes a processor controlled to: determine an interval time to poll a monitored device in a queue of monitored devices based on a current processing time of a given monitored device being polled, and an average processing time for previously polled monitored devices; adjust a polling rate such that the interval time is between a minimum polling interval target and a maximum polling interval target; poll the monitored devices in the queue according to the polling rate; receive, in response to the poll, from the monitored devices in the queue, current software version indicators of software installed at the monitored devices; and transmit, to a software patch difference device, the current software version indicators, the software patch difference device to determine which of the monitored devices have been updated since a last poll based on the current software version indicators.
