Tele2, one of Europe’s fastest growing telecom operators, with an IT environment spread over eleven countries required an alternative to Nagios to hep them monitor their severs and applications, which involved monitoring everything from hardware components to user emulation. In total there were about 2,000 monitored severs and just as many monitored applications that they were monitoring with Nagios,
So why was one of Europe’s leading telecom operators looking for an alternative to Nagios, a highly regarded IT monitoring solution?
According to Charlie Candergart, a developer and monitoring technician at Tele2 “we decided to change our monitoring system to OP5 Monitor because we were looking for better support and a product that would keep up with development trends”
With the help of OP5’s technical engineers. commissioning of the new system was a smooth transition for the Tele2 team, thanks in part to OP5 Monitor being highly compatible with Nagios.
“We definitely got a much better product with OP5 Monitor than we had in Nagios, which also provided us with a number of new functions and the overall look and feel is a big improvement”
Over time since transitioning to OP5 Monitor, Tele2 have developed a number their own plug-ins. Their adaptations have primarily been related to various user emulations, but they also developed some for monitoring e.g. databases and I/Os.
Based on requirements from Tele2’s server and system administration, the company developed user emulation for its most critical systems. The emulation serves to gather statistics regarding different systems, at which time their operational reliability is ranked with availability number. This makes it possible to monitor the availability of the company’s internal systems and applications from a user perspective. Monthly availability targets have been set for each system. Trends are followed on an ongoing basis throughout the month to make it possible to remedy any problems as early as possible.
The system owners have been provided monitors to keep tabs on “their operating parameters”. This has enabled the company to tap into the workers’ competitive nature – everyone wants to be on top of the rankings. Even though the monitoring screens are jokingly referred to as the “black list” internally, the system effectively cultivates the quality work of the organization.
“The best thing about op5 Monitor is its flexibility. It is so easy to monitor exactly what you want to. There is an abundance of ready-to-use plug-ins on the web. At the same time, it is simple to modify or develop our own modules” says Charlie Candergart.
“As a company, op5 has extremely talented and alert employees. Over the years, we have had a lot of contact with developers and support staff, all of whom have been very pleasant and helpful. They even have testing environments, so they can quickly reproduce our problems and find solutions.”
