Firms say they lack the information to troubleshoot and determine the cause of network problems.
Half of network professionals responding to a survey carried out by Network Instruments said they were unsure whether performance problems were caused by the network or by applications.
The survey, which covered 125 network engineers, IT directors and CIOs across Europe and North America, also found that 43% believe a lack of information about problems and their causes is the most common problem on their network.
The survey also found that 40% of respondents admitted they needed to improve their ability to troubleshoot intermittent errors. And 44% of IT teams reported spending between 20% and 40% of their time locating the cause of network problems.
In addition, 22% identified prioritising traffic as the largest network concern.
Ian Cummins, European sales director at Network Instruments, said, "Engineers and CIOs often tell me they find it challenging to identify latency and performance issues on their network and resolve the issues before they adversely affect the user.
“Without the right analytical tools, troubleshooting can be a lot like trying to find a needle in a haystack."
