Kibana and ElasticSearch over Haproxy logs

2 minute read Published:

One of the most interesting things about open source, is the capability of being able to deploy software that can compete with tools more emblazoned or “enterprise” grade appliance. One of these software is HaProxy which, with some tuning and doc reading, can easily sustain 20k-30k connection per seconds on a 1GB dual core virtual machine. Of course, during testing phase and during live you would need to see haproxy logs, in particular error logs but also the access one; since the amount of data is rather big, you’d prefer having another server that has to do with write on the disk and let haproxy only deal with load balancing.
