Most of the network -related and location related polling engines within the IMS operate on an 8 second cycle (though this configurable at the cost of data accuracy/user experiences).
Practically, a polling cycle timeline works as follows:
- (Wake up from sleep if not first poll)
- Get the data from the device
- If SNMP
- GETs and GETNEXTs on targeted OIDs only (no full walks)
- If SSH
- Targeted commands
- Compression enabled (to minimise load on network)
- If HTTP
- Targeted endpoints (URLs)
- Parse, process and export the data.
- If SNMP
- Sleep for whatever is left of the 8 second cycle.
