Kicking the tyres on OpenTSDB

By | Technical | No Comments

One of the big buzzwords in IT at the moment is “big data” – data in such large quantities that it’s not feasible to analyse using your traditional set of tools. Thankfully this isn’t a problem that Anchor has to deal with, but we almost wish we did. We collect a lot of data about the servers we manage, way more than most other hosting providers: on a typical server we monitor and track a couple dozen metrics to know how healthy it is and whether that’s changing over time. This is good, but it’d be great if we could easily store lots more data. What if we didn’t limit ourselves to keeping a year of data? What if we collected data every few seconds instead of every minute? Even…

A little news on backups and why they matter

By | Company News, Technical | No Comments

One of our sysadmins has been cleaning up and auditing our backups recently, and we thought we’d look at some of the numbers involved and how they’ve changed over time. Several years ago we used tapes exclusively, and they were always taken offsite. We don’t have the numbers from that time, but every fully-managed server came with backups included. AMANDA is still our backup software of choice and it’s been a reliable system for many years. That said, tapes aren’t really a good match for many of our customers’ needs, and the costs can be prohibitive. That’s why we developed our onsite disk-based backup solution. As well as being able to offer large amounts of storage at a much lower cost to the customer, the experience is actually better because…

Web hosting statistics vs Google Analytics

By | Company News, Technical | No Comments

We get the request from time to time, “can you track XYZ in the website statistics for our web hosting?” We get a bit of “Your statistics reports aren’t very pretty”. We include two very commonly used statistics generators with all shared web hosting, AWStats and Webalizer. Both of these tools generate statistics using the logs that the web server keeps for every page request. These logs look something like this: 88.179.0.194 – – [11/Dec/2008:04:48:03 +1100] “GET / HTTP/1.1” 302 20 “http://www.google.fr/search?hl=fr&q=anchor+blog&start=10&sa=N” “Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; fr; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4” Without explaining the log file in detail, in summary, the above line tells us: What IP address each request comes from The date and time of the request If the user clicked on a link to…
