SNMPv2 Diagnostic Counters
The SNMPv2-MIB.mib file provides a number of counters to aid in debugging SNMP problems.
Table 5-14 lists some of these diagnostic counters.
Table 5-14. Diagnostic Counters from SNMPv2-MIB
Variable ID Mapping Description
snmpInPkts snmp 1
The total number of messages delivered to the SNMP entity
from the transport service.
snmpInBadVersions snmp 3
The total number of SNMP messages that were delivered
to the SNMP entity and were for an unsupported SNMP
version.
snmpInBadCommunityNames snmp 4
The total number of community-based SNMP messages
delivered to the SNMP entity that used an invalid SNMP
community name.
snmpInBadCommunityUses snmp 5
The total number of community-based SNMP messages
delivered to the SNMP entity that represented an SNMP
operation that was not allowed for the community named
in the message.
snmpInASNParseErrs snmp 6
The total number of ASN.1 or BER errors encountered by
the SNMP entity when decoding received SNMP messages.
snmpEnableAuthenTraps snmp 30
Indicates whether the SNMP entity is permitted to generate
authenticationFailure traps. The value of this object
overrides any configuration information. It therefore
provides a means of disabling all authenticationFailure
traps.
snmpSilentDrops snmp 31
The total number of Confirmed Class PDUs delivered to
the SNMP entity that were silently dropped because the
size of a reply containing an alternate Response Class PDU
with an empty variable-bindings field was greater than
either a local constraint or the maximum message size
associated with the originator of the request.
snmpProxyDrops snmp 32
The total number of Confirmed Class PDUs delivered to
the SNMP entity that were silently dropped because the
transmission of the message to a proxy target failed in a
manner other than a time-out such that no Response Class
PDU could be returned.
System Log Files
In addition to lists of events and alarms, vSphere components generate assorted logs. These logs contain
information about activities in your vSphere environment.
View System Log Entries
You can view system logs generated by vSphere components.
The following task describes how to access and view system logs.
Procedure
1 From the Home page of a vSphere Client connected to either a vCenter Server system or an ESX/ESXi host,
click System Logs.
2 From the drop-down menu, select the log and entry you want to view.
