We use Kibana at work (which is a nice UI to sit on top of logstash – I think logstash has adopted Kibana now that I check up on it – which also makes use of elasticsearch) as our visual tool to dig into our system logs from instances we host on AWS. To my dismay I received the alert this morning that we were running out of disk space on our dedicated logging box (it aggregates rsyslog data, with our other production boxes pumping information through to logstash).

I’m an avid reader and long time lurker of Hacker News (HN – for short), it’s definitely my number one go to source for current tech industry information. I know I’m sure to find some interesting tidbits here and there and spend at least a few hours per week reading articles I find linked.
