Migrated Router Settings from 4.15.07 to 4.16.xx

[#1]

One of the key changes from 4.15.xx to 4.16.xx was the replacement of the netty router to the nginx router.

While the migration process tries to take care of the settings it's possible one or more may belost or the configuration needs a tidy. Older netty settings will no longer have an impact but could be confusing to the read.

The following is a list of older Netty settings that are no longer required and have been replaced

by the newer nginx configuration. It's also worth noting that Netty timeouts are usually expressed in millseconds whereas nginx are usually seconds.

Here are some key settings that might need to be considered:

Netty (4.15.07)	Nginx	New Default
ServerContainer.max.clients	load.balancing.driver.nginx.limit_conn	5000
Client.pool.connection.timeout	load.balancing.driver.connect.timeout	5 seconds
Client.pool.iotimeout	load.balancing.driver.proxy.read.timeout	57

To change setting in 4.16.xx you have to use the Change with configuration (cwc) method described in the documentation, so for example to set:

load.balancing.driver.connect.timeout

Create the file $APIGEE_ROOT/customer/application/router.properties

add this entry

conf_load_balancing_load.balancing.driver.connect.timeout=<timeout_in_seconds>

restart the edge-router.
