Packet sample action in tc(8) Linux Packet sample action in tc(8)
NAME
sample - packet sampling tc action
SYNOPSIS
tc ... action sample rate RATE group GROUP [ trunc SIZE ] [ index INDEX ]
tc ... action sample index INDEX
DESCRIPTION
The sample action allows sampling packets matching classifier.
The packets are chosen randomly according to the rate parameter, and are sampled using the psample generic netlink channel. The user can
also specify packet truncation to save user-kernel traffic. Each sample includes some informative metadata about the original packet, which
is sent using netlink attributes, alongside the original packet data.
The user can either specify the sample action parameters as presented in the first form above, or use an existing sample action using its
index, as presented in the second form.
SAMPLED PACKETS METADATA FIELDS
The metadata are delivered to userspace applications using the psample generic netlink channel, where each sample includes the following
netlink attributes:
PSAMPLE_ATTR_IIFINDEX
The input interface index of the packet, if there is one.
PSAMPLE_ATTR_OIFINDEX
The output interface index of the packet. This field is not relevant on ingress sampling
PSAMPLE_ATTR_ORIGSIZE
The size of the original packet (before truncation)
PSAMPLE_ATTR_SAMPLE_GROUP
The psample group the packet was sent to
PSAMPLE_ATTR_GROUP_SEQ
A sequence number of the sampled packet. This number is incremented with each sampled packet of the current psample group
PSAMPLE_ATTR_SAMPLE_RATE
The rate the packet was sampled with
OPTIONS
rate RATE
The packet sample rate. RATE is the expected ratio between observed packets and sampled packets. For example, RATE of 100 will lead
to an average of one sampled packet out of every 100 observed.
trunc SIZE
Upon set, defines the maximum size of the sampled packets, and causes truncation if needed
group GROUP
The psample group the packet will be sent to. The psample module defines the concept of groups, which allows the user to match spe-
cific sampled packets in the case of multiple sampling rules, thus identify only the packets that came from a specific rule.
index INDEX
Is a unique ID for an action. When creating new action instance, this parameter allows to set the new action index. When using
existing action, this parameter allows to specify the existing action index. The index must 32bit unsigned integer greater than
zero.
EXAMPLES
Sample one of every 100 packets flowing into interface eth0 to psample group 12:
tc qdisc add dev eth0 handle ffff: ingress
tc filter add dev eth0 parent ffff: matchall
action sample rate 100 group 12 index 19
Use the same action instance to sample eth1 too:
tc qdisc add dev eth1 handle ffff: ingress
tc filter add dev eth1 parent ffff: matchall
action sample index 19
