syslog-ng Open Source Edition 3.16 - Release Notes

tcp-keepalive-time()

Type: number [seconds]
Default: 0

Description: Specifies the interval (in seconds) between the last data packet sent and the first keepalive probe. This option is equivalent to /proc/sys/net/ipv4/tcp_keepalive_time. The default value is 0, which means using the kernel default.

Caution:

The tcp-keepalive-time(), tcp-keepalive-probes(), and tcp-keepalive-intvl() options only work on platforms which support the TCP_KEEPCNT, TCP_KEEPIDLE,and TCP_KEEPINTVL setsockopts. Currently, this is Linux.

A connection that has no traffic is closed after tcp-keepalive-time() + tcp-keepalive-intvl() * tcp-keepalive-probes() seconds.

Available in syslog-ng OSE version 3.4 and later.
