Leif Hedstrom updated TS-153: ----------------------------- Fix Version/s: (was: 6.0.0) 4.2.0 > "Dynamic" keep-alive timeouts > ----------------------------- > > Key: TS-153 > URL: https://issues.apache.org/jira/browse/TS-153 > Project: Traffic Server > Issue Type: New Feature > Components: Core > Reporter: Leif Hedstrom > Priority: Minor > Labels: A > Fix For: 4.2.0 > > > (This is from a Y! Bugzilla ticket 1821593, adding it here. . Originally > posted by Leif Hedstrom on 2008-03-19): > Currently you have to set static keep-alive idle timeouts in TS, e.g. > CONFIG proxy.config.http.keep_alive_no_activity_timeout_in INT 8 > CONFIG proxy.config.http.keep_alive_no_activity_timeout_out INT 30 > even with epoll() in 1.17.x, this is difficult to configure, and put an > appropriate timeout. The key here is that the > settings above need to assure that you stay below the max configured number > of connections, e.g.: > CONFIG proxy.config.net.connections_throttle INT 75000 > I'm suggesting that we add one (or two) new configuration options, and > appropriate TS code support, to instead of > specifying timeouts, we specify connection limits for idle KA connections. > For example: > CONFIG proxy.config.http.keep_alive_max_idle_connections_in INT 50000 > CONFIG proxy.config.http_keep_alive_max_idle_connections_out INT 5000 > (one still has to be careful to leave head-room for active connections here, > in the example above, 20000 connections > could be active, which is a lot of traffic). > These would override the idle timeouts, so one could use the max_idle > connections for incoming (client) connections, > and the idle timeouts for outgoing (origin) connections for instance. > The benefit here is that it makes configuration not only easier, but also a > lot safer for many applications. -- This message was sent by Atlassian JIRA (v6.1#6144)
