graph discards out - explanation

[zlabovic]

Hello,

Can anyone tell me what exactly, in cacti grapghs, do the terms discards out and
discards in mean? WHat type of error is that?
Cacti graph is detecting these discards on my virtual tunnel interface whereas on the actual physical (fethernet) interface there are no errors. The device is a cisco router.

Solution can be found in ./resource/snmp_queries/interface.xml that defines all OIDs queried by the Interface Traffic Templates

Code: Select all

                <ifInDiscards>
                        <name>Discarded Packets In</name>
                        <method>walk</method>
                        <source>value</source>
                        <direction>output</direction>
                        <oid>.1.3.6.1.2.1.2.2.1.13</oid>
                </ifInDiscards>
                <ifOutDiscards>
                        <name>Discarded Packets Out</name>
                        <method>walk</method>
                        <source>value</source>
                        <direction>output</direction>
                        <oid>.1.3.6.1.2.1.2.2.1.19</oid>
                </ifOutDiscards>

This denotes the SNMP OIDs that are queried by cacti. They conform to some RFCxxxx standard (don't know by heart)
