IRC output plugin rate-limiting


Hi developers,

Right now the IRC output plugin is limited to 0.5 messages per second by the looks of reading the source code for the irc bot used.

For our private IRC server this is not enough and #logstash often is hours, or even days, behind with it's output.

The bot have options for setting message queues both for the client and for what the server allows. It would be nice to be able to set these options as plugin options in logstash.

Cheers, Nafallo

We've just started using the IRC plugin and immediately ran into this issue.

Nafallo, any chance you could work on a patch?

Scanning through the code, looks like this is a a setting:

85: mps = @bot.config.messages_per_second ||

Yeah, I can expose messages_per_second.

Here's the full list of options, any others you want to be able to tune?

I found some docs in

server_queue_size might also be useful in addition to messages_per_second.
