Lightweight log delivery agent works w/ fluentd
fluent-agent-lite.conf に存在しないログファイルを書いている場合、
$ sudo /etc/init.d/fluent-agent-lite start
failed. (timeout after 10sec)
とエラーが出ることがある。エラーが出ずに ok. となることもある。
対処法は2つ考えられる
手元では 2. の修正を加えている、方針を伺ってから pull req したい。
REPRODUCE PROCEDURE:
ssh -t hostname sudo /etc/init.d/fluent-agent-lite restart
It seems using disown
to daemonize is bad.
Some deploy tools such as mina
uses ssh -t
as default. I'm happy if this is fixed.
I also heard from my colleague as fluent-agent-lite could not be booted via knife-solo (I did not examine well, though)
@tagomoris I've noticed that fluent-agent-lite reads 10 lines of log file when we restarts it because tail command prints the last 10 lines of a file as default.
Should fluent-agent-lite read 0 lines at restarting using -n 0
option of the tail command? Otherwirse, it would send again some same lines of log at restarting.
I can make patch for this. Any opinions?

Usually, fluent-agent-lite dies if tail
command dies by some reasons (for example, someone killed tail process by mistake).
However, during reconnect loop of fluent-agent-lite (AgentLite.pm#L113-L119), fluent-agent-lite does not detect the tail's death, and results in zombie tail process (detection is at AgentLite.pm#L203)
