Helpdesk employee,

bosworX B.V.

As a helpdesk employee I’m first to answer the customer via phone or e-mail and help solve issues. I’m also watching the monitoring system, and act pro-active on any errors. With major issues i gather all the correct information and escalate this information in a ticket to a Back Office employee.

-on-site support
-Inventory of larger projects
-Basic administration of servers
-Watching Back Office tickets
-Making sure the tickets are processed correctly

Check_mk bosworX

The main goal was to monitor everything! And with everything they ment, everyting.
We ended up with a complete check_mk farm of 5 servers, using the distributed monitoring function we could easily scale.
1 main check_mk server hosting the webinterface and monitoring linux systems
4 slaves, monitoring windows hosts, WATO and specific network devices.

later on we also added customers with on-site check_mk servers, using VPN to communicate to the main check_mk server so everything was on 1 big pile.

Some stats
Hosts monitored: 921
Services monitored: 39.907
on-site check_mk: 9
