Logs

Analysing your Web Server logs be it apache or IIS can be a big task and one well suited for tool such as awstats. Awstats gives you a good overall view of traffic and stats for your site but a stat I always want to look at is requests per second as it has a direct correlation to CPU usage etc. This will give you a more granular view of traffic and is especially useful for capacity management when it comes to API’s.
