Is your IT team regularly fielding questions about slow webpage downloads, crashed servers and lost emails? Malfunctions and failures in operational processes can result in loss of time and productivity, and more importantly – money. Network monitoring software can help by monitoring the different processes in the network, performing analysis and alerting IT personnel as soon as an error occurs. 

Here is my list of five common issues that better network monitoring can help you resolve.

  1.  Applications Are Slow

Your IT infrastructure needs constant review. For example, are there overloaded components? Is the temperature of your servers acceptable? Are there servers that restart every now and then during the night? Do you know when the hard disks are going to be full? Network monitoring can provide detailed data and historical reports about all of your network components. This analysis will enable you to see the usage trends and uncover where resources are going to run out. A network monitoring tool will also warn you when something uncommon occurs like server outages, or when certain values reach a defined threshold, so you can act before an incident occurs.

  1.  The Network Isn’t Secure

Firewalls and anti-virus programmes can lull companies into a false sense of security. Despite having the software installed, malware attacks on corporate IT networks still happen and often go undetected until the late stages of the breach. Businesses should consider using a network monitoring tool as a strategic part of securing their IT network and as a sensible add-on to virus scanners, email security programmes and firewalls. A network monitoring tool will detect unusual behaviour and will pick up on connections from unknown source addresses accessing the network through your firewall. Another helpful feature which some network monitoring tools offer is a similar sensor analysis which can identify strange interconnections between sensors.

  1.  Phone Call & Video Streaming Quality Is Poor

When the sound quality of Voice over IP (VoIP) calls drops dramatically, or video streaming is frequently lagging, you need to investigate the relevant parameters like jitter, packet loss, or the packet delay variation of the network connection. Both VoIP and video streaming services rely on a steady stream of data packets. For example, quality of service suffers when User Datagram Protocol (UDP) packets are not received in a timely fashion, or if packets are lost or out of order. A good network monitoring tool will enable you to measure the quality of your network connection by sending UDP packets between two remote probes and analysing various network parameters.

  1.  Browsing Your Website Is Horrible

Online shops need to be available day and night. Equally, when customers are on your website, it needs to perform effectively. If a transaction fails due to technical errors, or browsing your website is a horrible experience, you will lose customers and money. The same applies if the page is unacceptably slow. A network monitoring tool will alert you immediately if anything goes wrong with your web page, or when it shows unusual behaviour, such as being too slow.

  1.  Database Performance Is Bad

If your database performance is low, you need to understand where the problem is stemming from. Unfortunately, examining the reason for bad performance of, for example, SQL servers can be a painful task. A network monitoring tool can help support the maintenance of your database. For example, if the performance is low at specific times, this might be a result of overly high numbers of user connections at the same time. A network monitoring tool will also alert you if the percentage of pages found in the buffer cache are too low, so that you can increase the amount of memory available to the SQL server. Monitoring the response time of queries will also allow you to check if the response value is as expected.
