=== Need to limit bandwidth used by {beatname_uc}?
|
|
|
|
If you need to limit bandwidth usage, we recommend that you configure the network stack on your OS to perform
|
|
bandwidth throttling.
|
|
|
|
For example, the following Linux commands cap the connection between {beatname_uc} and Logstash by setting a
|
|
limit of 50 kbps on TCP connections over port 5044:
|
|
|
|
[source,shell]
|
|
----------------------------------------------------------------------
|
|
tc qdisc add dev $DEV root handle 1: htb
|
|
tc class add dev $DEV parent 1:1 classid 1:10 htb rate 50kbps ceil 50kbps
|
|
tc filter add dev $DEV parent 1:0 prio 1 protocol ip handle 10 fw flowid 1:10
|
|
iptables -A OUTPUT -t mangle -p tcp --dport 5044 -j MARK --set-mark 10
|
|
----------------------------------------------------------------------
|
|
|
|
Using OS tools to perform bandwidth throttling gives you better control over policies. For example, you can use
|
|
OS tools to cap bandwidth during the day, but not at night. Or you can leave the bandwidth uncapped, but assign a low priority to the traffic.
