ESXiからのsnmp trap level設定

　VMware vSphere 6.7のESXiからsnmp trapを上げるようにしたのだが、あまりにも大量のinfoが上がってくるので、その対応。

esxcliで送出レベルを設定する。
設定後snmpdを再起動すると反映される。

----
Usage: esxcli system snmp set [cmd options]

Description:
  set                   This command allows the user to set up ESX SNMP agent.

Cmd options:
  -a|--authentication=
                        Set default authentication protocol. Values: none,
                        MD5, SHA1
  -c|--communities=
                        Set up to ten communities each no more than 64
                        characters. Format is: community1[,community2,...]
                        (this overwrites previous settings)
  -e|--enable=    Start or stop SNMP service. Values: [yes|no,
                        true|false, 0|1]
  -E|--engineid=   Set SNMPv3 engine id. Must be at least 10 to 32
                        hexadecimal characters. 0x or 0X is stripped if found
                        as well as colons (:)
  -y|--hwsrc=      Where to source hardware events from IPMI sensors or
                        CIM Indications. One of: indications|sensors
  -s|--largestorage=
                        Support large storage for hrStorageAllocationUnits *
                        hrStorageSize. Values: [yes|no, true|false, 0|1].
                        Control how the agent reports
                        hrStorageAllocationUnits, hrStorageSize and
                        hrStorageUsed in hrStorageTable. Setting this
                        directive to 1 to support large storage with small
                        allocation units, the agent re-calculates these values
                        so they all fit Integer32 and hrStorageAllocationUnits
                        * hrStorageSize gives real size of the storage ( Note:
                        hrStorageAllocationUnits will not be real allocation
                        units if real hrStorageSize won't fit into Integer32
                        ). Setting this directive to 0 turns off this
                        calculation and the agent reports real
                        hrStorageAllocationUnits, but it might report wrong
                        hrStorageSize for large storage because the value
                        won't fit into Integer32.
  -l|--loglevel=   System Agent syslog logging level:
                        debug|info|warning|error
  -n|--notraps=    Comma separated list of trap oids for traps not to be
                        sent by agent. Use value 'reset' to clear setting
  -p|--port=      Set UDP port to poll snmp agent on. The default is
                        udp/161. May not use ports 32768 to 40959
  -x|--privacy=    Set default privacy protocol. Values: none, AES128
  -R|--remote-users=
                        Set up to five inform user ids. Format is: user/auth-
                        proto/-|auth-hash/priv-proto/-|priv-hash/engine-
                        id[,...] Where user is 32 chars max. auth-proto is
                        none|MD5|SHA1, priv-proto is none|AES. '-' indicates
                        no hash. engine-id is hex string '0x0-9a-f' up to 32
                        chars max.
  -r|--reset            Return agent configuration to factory defaults
  -C|--syscontact= System contact string as presented in sysContact.0. Up
                        to 255 characters
  -L|--syslocation=
                        System location string as presented in sysLocation.0.
                        Up to 255 characters.
  -t|--targets=    Set up to three targets to send SNMPv1 traps to.
                        Format is: ip-or-hostname[@port]/community[,...] The
                        default port is udp/162. (this overwrites previous
                        settings)
  -u|--users=      Set up to five local users. Format is: user/-|auth-
                        hash/-|priv-hash/model[,...] Where user is 32 chars
                        max. '-' indicates no hash. Model is one of
                        (none|auth|priv).
  -i|--v3targets=  Set up to three SNMPv3 notification targets. Format
                        is: ip-or-hostname[@port]/remote-user/security-
                        level/trap|inform[,...].
