Icinga2 plugins package using Request Manager to manage requests to machines and use Cache when possible thus to remove load on worker machine and reduce UDP requests quantity.

• Redis (Key => Val DB Database using RAM to stock data)
• Hiredis (C Redis C implementation)
• EasySNMP (Net-SNMP lib created using Cython)
• Nagiosplugin (Nagios plugin Python lib)

Testing 4 Python libs:

• EasySNMP
• NetSNMP
• PySNMP
• Unix SNMP lib native Unix function called with os.popen as NativeSNMP

Tests were executed using same OIDs and SNMPWalk function.

Results in seconds (s):

EasySNMP manages very well big quantity of requests using single SNMP session.
