Yonas Habteab wrote a very nice blog post about how to monitor a web server:
Unfortunately he didn’t reveal how he came up with the cool teaser image at the start of his article.
Actually, that was the only reason why I started reading it…
Could Yonas (or someone else) enlighten us please?
My guess is they used a stock photo, which is a little odd (imho) for a blog at icinga.com specifically about icinga’s capabilities. The x-axis does not appear to be a timeseries.
You may want to check out collectd, statsd, carbon/graphite/grafana. grafana can be used with icinga2 perf data (in addition to other sources) or viewed directly in icingaweb2 with the graphite module.
