A easy to set-up holistic network monitoring software

Your whole business depends on a well-working network infrastructure. However, even networks at small companies can get hugely complicated over time and it is easy to lose the overview and keep an eye on everything.

Checkmk can help you quickly monitor your entire network and it doesn’t cover only the major devices, but a broad set of vendors also outside the mainstream. And this all without complicated configurations and endless alarms. With a few clicks, you will be able to monitor all your network devices, e.g.

  • Switches & Routers — Monitor packet rates, error rates, state and bandwith of ports, error rates, CPU utilization, fans, power supply, temperature and more. Supported devices include, e.g. Alcatel-Lucent, Cisco, Brocade, Dell, Enterasys, Extreme Networks, Huawei, Intel, Juniper, TP-Link
  • Wireless — Also monitor your wireless networks, e.g. state of access points, signal strength and connected devices for Aerohive, Aruba Networks, CBL, MikroTik, Netgear, Fritz!Box, etc. devices
  • Firewalls — Ensure the security of your network by monitoring the health, VPN tunnel state, high availability state and more of your BlueCat, Checkpoint, F5, FireEye, FortiGate, IBM, Palo Alto Networks, etc. devices

With Checkmk it is easy to monitor all your network interfaces. But should you really monitor all ports? Yes! You will realize it is less work than you think and you will discover broken patch cables, bad configurations and much more. This way, in the end, instead of spending money on server upgrades or IT consultants, because your users complain about slow applications, you actually fix the origin of your problems. Of course, only if it was the network.

Monitoring for all your network devices

Ultra efficient network monitoring

Checkmk uses a rule-based concept for configuring your monitoring. This becomes especially powerful, when monitoring a large number of similar devices in contrast to a template-based approach, where you need to configure each 'sensor'.

With just a couple of rules, you can configure your entire network monitoring, e.g. monitoring only the error rate for access ports.

Routers and switches can have several hundred SNMP messages – it is important to monitor only what really matters. Checkmk knows what data matters and filters the data for you, so that you get see the data you need.

For small networks and ISPs

Checkmk comes with more than 1,700 preconfigured checks and can highly likely monitor any switch, router or firewall you have.

You can monitor the network interfaces of low-end switches with just a couple of ports. But you can also monitor huge core switches with several hundred ports or the devices powering the internet — monitor BGP sessions, routing engines, fans, memory, file systems and more for your BGP routers.

Understand switch ports usage

Ever stood in front of a switch and wondered which ports are actually used and which not and someone just didn't remove the cable? Ever unplugged the internet of the CEO, because the port looked like not in use, but he was just on a business trip?

Checkmk combines real-time data and historic data to understand, which ports of a switch are in use. With the switch port statistics feature, you can see immediately which port is up/down/free, the speed, if it is in use and when it was used the last time.

VPN and remote workplace monitoring

Avoid capacity bottlenecks, bandwidth and performance issues, or configuration errors from slowing down your VPN and remote workplace architecture. This is the only way to ensure that your employees can easily access the tools and applications they need from home or wherever they work.

With Checkmk you are able to monitor the status and the number of your active VPN tunnels and the amount of bytes transferred via VPN, so that you can detect problems early and guarantee secure remote access to your company infrastructure at any time.

Prevent your VPN gateway from becoming a bottleneck in your remote architecture by easily monitoring device CPU usage with Checkmk. In this way, Checkmk helps you to react to possible bottlenecks at an early stage.

With remote workplaces it is useful to monitor several parameters at once to ensure smooth operation. Here, too, you should always keep an eye on the performance utilization of your gateway. Checkmk also helps you to keep an eye on the resource capacities of your virtual platform. Because only if sufficient CPU, RAM or Storage IO are available, a smooth operation and a possible scaling of the virtual workstations is guaranteed.
