| ===== SSE(Server Sent Events Process) ===== | ===== SSE(Server Sent Events Process) ===== | ||
| + | The SSE subscription drives real time update receipt in the angular ems-nova front end application. | ||
| + | Server-Sent Events (SSE) is a server push technology enabling a client to receive automatic updates from a server via an HTTP connection, and describes how servers can initiate data transmission towards clients once an initial client connection has been established. | ||
| + | |||
| + | In this case nova subscribes to the idms-proxy sse endpoint and listens for updates: | ||
| + | < | ||
| + | / | ||
| + | </ | ||
| + | |||
| + | The SSE touchpoints for processing are as follows(see also diagram below): | ||
| + | - Gorm listener events for ticket, alarm, element inserts or updates are pushed from Ticketer and SnmpManager onto rabbitmq. | ||
| + | - Elastic Replicator consumes messages from these queues, processes them using the sql queries and updates or inserts new records into elastic search. It also pushes the events onto a queue which is consumed by idms-proxy. | ||
| + | - idms-proxy consumes a queue which receives event messages from elastic-replicator. | ||
| + | - Nova front end is subscribed to proxies sse endpoint /replicator and receives messages for real time page updates. | ||
