__END__

=head1 MODE

Check interfaces.

=over 8

=item B<--add-global>

Check global port statistics (by default if no --add-* option is set).

=item B<--add-status>

Check interface status.

=item B<--add-duplex-status>

Check duplex status (with --warning-status and --critical-status).

=item B<--add-traffic>

Check interface traffic.

=item B<--add-errors>

Check interface errors.

=item B<--add-cast>

Check interface cast.

=item B<--add-speed>

Check interface speed.

=item B<--add-volume>

Check interface data volume between two checks (not supposed to be graphed, useful for BI reporting).

=item B<--add-optical>

Check interface optical metrics.

=item B<--check-metrics>

If the expression is true, metrics are checked (default: '%{opstatus} eq "up"').

=item B<--warning-status>

Define the conditions to match for the status to be WARNING.
You can use the following variables: %{admstatus}, %{opstatus}, %{duplexstatus}, %{display}

=item B<--critical-status>

Define the conditions to match for the status to be CRITICAL (default: '%{admstatus} eq "up" and %{opstatus} ne "up"').
You can use the following variables: %{admstatus}, %{opstatus}, %{duplexstatus}, %{display}

=item B<--warning-*> B<--critical-*>

Thresholds.
Can be: 'total-port', 'total-admin-up', 'total-admin-down', 'total-oper-up', 'total-oper-down',
'in-traffic', 'out-traffic', 'in-error', 'in-discard', 'out-error', 'out-discard',
'in-ucast', 'in-bcast', 'in-mcast', 'out-ucast', 'out-bcast', 'out-mcast',
'speed' (b/s).

And also: 'input-power' (dBm), 'bias-current' (mA), 'output-power' (dBm), 'voltage' (mV), 'module-temperature' (C).

=item B<--units-traffic>

Units of thresholds for the traffic (default: 'percent_delta') ('percent_delta', 'bps', 'counter').

=item B<--units-errors>

Units of thresholds for errors/discards (default: 'percent_delta') ('percent_delta', 'percent', 'delta', 'deltaps', 'counter').

=item B<--units-cast>

Units of thresholds for communication types (default: 'percent_delta') ('percent_delta', 'percent', 'delta', 'deltaps', 'counter').

=item B<--nagvis-perfdata>

Display traffic perfdata to be compatible with nagvis widget.

=item B<--interface>

Set the interface (number expected) example: 1,2,... (empty means 'check all interfaces').

=item B<--name>

Allows you to define the interface (in option --interface) by name instead of OID index. The name matching mode supports regular expressions.

=item B<--speed>

Set interface speed for incoming/outgoing traffic (in Mb).

=item B<--speed-in>

Set interface speed for incoming traffic (in Mb).

=item B<--speed-out>

Set interface speed for outgoing traffic (in Mb).

=item B<--force-counters32>

Force to use 32 bits counters (even in snmp v2c and v3). Should be used when 64 bits counters are buggy.

=item B<--reload-cache-time>

Time in minutes before reloading cache file (default: 180).

=item B<--oid-filter>

Define the OID to be used to filter interfaces (default: ifName) (values: ifDesc, ifAlias, ifName, IpAddr).

=item B<--oid-display>

Define the OID that will be used to name the interfaces (default: ifName) (values: ifDesc, ifAlias, ifName, IpAddr).

=item B<--oid-extra-display>

Add an OID to display.

=item B<--display-transform-src> B<--display-transform-dst>

Modify the interface name displayed by using a regular expression.

Example: adding --display-transform-src='eth' --display-transform-dst='ens'  will replace all occurrences of 'eth' with 'ens'

=item B<--show-cache>

Display cache interface data.
