Troubleshooting critical issues (bugs, latencies, mem leaks, configuration issues...) in your delivered big IT project without full-stack profiling and real time monitoring – it’s like looking for a needle in a haystack.
I’ve been in both situations, delivering large projects both with and without, and I must say it's a luxury to actually see what is happening under the hood, in real time, that you soon can't live without. Also I must suggest to have a real time dashboards showing the full picture, ie. both tech and business KPIs in one unified view. I wouldn’t say no to using AppDynamics, Splunk and Qlikview for the job but there are cheaper alternatives (for example Elastic search/Logstash/Kibana can be used to get full overview of your logs). The cost? Yes, it does cost but it pays back fairly quick in your distributed environment when you have the volumes. Do I need it, you might ask? It depends. How critical is quality? What's the cost of incidents and downtime? Do you want to provide the tools for development to take full responsibility of their code all the way into production? Follow me on Twitter: mandus_engman
