10 Ways to Improve Your Output File

cloudcomputingjoke-300x259So you have written an app or log – it’s brilliant, it grabs all the data you need and runs like greased lightning. All you need to do now is ensure your output file has a nice clean format – preferably one that means Logscape does all the work for you! So here are some of my top tips.

1) Add a full time stamp to every line. You wouldn’t believe how much trouble can be caused by people using just times or dates. At the best, you have to struggle to get your data properly organised. At worst, you end up with a mess and data appears in the wrong place on the graph. Do it right, set the date and time!

2) Add a time zone to that stamp. My computer will never move time-zone, surely it’ll be fine? Don’t count on it. British Summer Time changing the system time on half your servers, servers being reset to US time, data centres moving locations… All these things can and will happen. Adding the time zone to the stamp gives you a cast iron assurance that the data will always be correct. That peace of mind is worth a few bytes.

Monitoring Platform Symphony.

Platform
Sitting at my desk, I was approached and asked this question.

Do you guys support Platform Symphony?

An interesting question, really we “support” most anything, Logscape has the base functionality for most tasks, and product “apps” just build upon that functionality, the app provides the workspaces, data types and sources, as well as the tools that Logscape will use to find the data you want. But at the end of the day it’s still Logscape, just it’s running a groovy script to fetch your metrics.

So what is the process that goes into making a Logscape App?

Quick and Dirty Logscape sizing guide

One of the first questions our customers hit us with is:

‘How much data can my server handle?’

I hate to be difficult and nothing is more frustrating than answering a question with a question but this is often the case with a data centric solution!

> Q: What is your server spec? A: It can handle X volume per day.
OR
> Q: What are your data volumes? A: You need this server setup

Monitoring a Web Application Stack (Nginx,Haproxy,Apache)

 

Dearchitectureveloping a responsive highly available web application is a complex task with many subcomponents. In the old days , a web application used to consist of a web server, usually Apache with a few cgi scripts to provide content dynamically. As the web grew in size so did the stack, the number of subcomponents,hosts involved increased in number and complexity. A simple web application can now easily consist of a web server, a load balancer, a few databases and a web framework such as Django or Rails. In this blog post we are going to look  at the  different Logscape Apps needed to monitor a web farm.
