Examples disclosed herein relate to a device management request from a remote management service. Examples include receipt of a device management from a remote management service through a firewall in a first device. The first device to provide the device management request to a second device via a local network and to receive a device management response from the second device. The first device to provide the device management response to the remote management service.

Receive device management request through firewall

Data is transferred from an input record to an index. The input record has a recorded unique device identification and recorded device data for a device, such as a printer. The recorded unique device identification is either a serial number of the device or another persistent identifying designation for the device. The recorded device data includes recorded usage data for the device. The index has at least one enduring record. Each enduring record has an enduring unique device identification and enduring device data. The recorded unique device identification and recorded device data for a device are read from the input record. The index is searched for a match to the recorded unique device identification. If a match to the recorded device information is not found in the index, an enduring record for the device is created in the index. An enduring usage data is read from the index. A difference in usage data is calculated from the enduring usage data and the recorded usage data. The index is updated with the recorded device data. The index is updated with the recorded device data by replacing enduring device data from the index with the recorded device data. The updates to the index are tracked.

Aggregating device collection data

A network address for an object device is corrected. A recorded network address and a recorded unique enduring identification for the object device are read from a record. The recorded network address is queried for a returned unique enduring identification. The recorded network address is queried by performing an SNMP Get call to the recorded network address or addressing a unique enduring identification query to the recorded network address and receiving the response to the query. The returned unique enduring identification is compared with the recorded unique enduring identification. Responsive to a mismatch between the returned unique enduring identification and the recorded unique enduring identification, a current network address for the object device is resolved and the recorded network address is replaced with the current network address.
