Using forms with Bootstrap-Dialog

var alertMessage = "";
var formTemplate = Backbone.Marionette.TemplateCache.get('#myTemplate');
var formString = formTemplate({ defaultDate: moment().add(90, 'days').format('YYYYMMDD') });

// remove the newlines. Bootstrap-Dialog doesn't like them (turns them into <br>'s)
formString = formString.replace(/[\n]/g, '');

RSyslog Forwarding Setup

Overview

I'm looking to centralize logging for our dev team into Elasticsearch via Logstash. The wrinkle is that we aren't a Java shop, so installing java on our hosts just to ship logs back to a central Logstash indexer is something we'd like to avoid. So, I'm approaching things as a chance to understand RSyslog and its capabilities as a log shipper.

Procedure

Set up TCP listening on the log index host

Uncomment the following lines in /etc/rsyslog.conf. This will enable the rsyslog daemon to listen for incoming requests on TCP port 514. We're using TCP here so that we can have some confidence that the messages from the agent hosts reach the indexer. (More on this below)
