Unified Agent Framework including Push-Based Discovery and Real-Time Diagnostics Features

Persistent storage may include a configuration management database (CMDB), the CMDB representing devices and software applications disposed within a managed network and relationships therebetween. A proxy server may be configured to relay discovery information between a plurality of endpoint devices associated with the managed network and the CMDB, wherein respective discovery agents are disposed within each of the endpoint devices, and wherein the proxy server contains one or more processors configured to execute program instructions that perform operations including: (i) receiving, from a discovery agent disposed within an endpoint device, a discovery payload, wherein the discovery payload includes: a configuration of the endpoint device and information regarding one or more software applications installed on the endpoint device, and wherein the proxy server did not request the discovery payload; and (ii) transmitting, by the proxy server, the discovery payload to the CMDB.
