The SNMP-Persist module is a backend for pass_persist feature of net-snmp. It simplifies the process of sharing user-specified data via SNMP and development of persistent net-snmp applications controlling a chosen MIB subtree. It is particularly useful if data gathering process takes too long. The responder is a separate thread, which is not influenced by updates of MIB subtree data. The answer to a snmp request is fast and doesn't rely on potentially slow source of data. WWW: https://metacpan.org/release/SNMP-Persist
