Notes

Note

  • Tested on vSphere 6.5

  • You need to reset the agent (to factory defaults) if you want to clear all community strings, trap targets, or filters

  • SNMP v3 configuration isn’t implemented yet

  • All modules requires API write access and hence is not supported on a free ESXi license.
