Story: Network-performance issues eat up tech time
Points out the need for more proactive management
I don't doubt that network admins are spending large quantities of time troubleshooting network issues. I do think that a large part of this is because many organizations have a lack of proactive monitoring of their networks. Problems are handled when something breaks. This is a bad approach as the resources that you end up spending trying to fix things after they broke (not to mention possible lost revenue, e-mail, etc from the broken network) are a lot more expensive than the cost of getting good monitoring in place. Good monitoring helps stop problems while they're still minor preventing the failure in the first place.
