Datadog is an infrastructure monitoring platform that is based in the cloud. It is a suite of modules, each of which monitors a different type of resource. Among the packages available from Datadog are network monitors and also server monitors. The server monitoring system offered by Datadog is called Datadog Infrastructure and it is able to monitor servers running Linux and Windows Server.
As this is a cloud-based system, it isn’t bound by the limits of one LAN. It can monitor servers anywhere and one Datadog Infrastructure account can group together the monitoring of many servers operating on many sites and also in the cloud. It is also possible to group the monitoring of servers running different operating systems.
The Datadog Infrastructure system displays all of the resources of all monitored servers on one page. For example, you can see all of the disk space usage of all servers. From an overview of all resource usage, you can zoom down to see all individual servers in one view, then drill through to each server and look at its statistics.
The data visualizations in the dashboard for Datadog Infrastructure make it easy to quickly understand all of the operations of all Linux servers. It is also possible to create a customized screen that collects all of the metrics that are important to you in one view.
The big advantage of Datadog Infrastructure is that, as well as showing the resource activities of your Linux servers, it will show all of the services that support your user-facing software. You can see all of the application stack that supports systems such as websites and spot where problems arise. This research capability extends down to the server’s performance.
You don’t need to sit and watch the dashboard of Datadog Infrastructure waiting for problems to arise because the service includes performance thresholds that will trigger alerts if crossed. These alerts show in the screens of the console and can also be forwarded on to key personnel by SMS, email, or collaboration system.
Datadog Infrastructure includes processing power in with the software so you don’t have to host the system on your site. Technicians access the dashboard through any standard Web browser from anywhere.
Datadog Infrastructure is offered in three editions:
- Free — Monitors up to five hosts and has a one-day data retention period.
- Pro – Has a 15-month data retention period and costs $15 per host per month.
- Enterprise – Includes AI-based performance thresholds and costs $23 per host per month.

Site24x7 is a cloud-based system monitoring platform and Infrastructure is its server monitoring module. The Infrastructure system has been extended to monitor networks as well.
The server monitoring part of the system can unify the monitoring of servers in different locations and also with different operating systems. Although the processing for the monitoring service takes place in the cloud, it needs an agent program installed on enrolled servers. The agent will install on Debian, Ubuntu, CentOS, Red Hat, Madriva, Fedora, SUSE, CoreOS, Raspberry Pi, and Arch Linux ARM as well as Windows Server.
The agent program gathers statistics and uploads those to the Site24x7 server for processing. The dashboard for the monitoring service is also resident in the cloud. It can be accessed by technicians through any standard Web browser from anywhere. The console includes a number of standard server monitoring screens. These can be customized by the user through drag-and-drop widgets.
The Infrastructure module includes other functions — it has a service to monitor networks as well. The network monitor covers device health and also reports on network traffic. These two functions spot performance issues that are caused by problematic network devices. It is also able to see when network capacity is reaching its limits on different links.
The network monitor is able to monitor switches, routers, load balancers, firewalls, VPNs, and wireless network APs. It has an autodiscovery service, which identifies all of the devices connec5ed to the network. It will also draw up a network topology map. Both the map and the inventory get automatically updated whenever a device is added, moved, or removed.
Both the server and network monitoring tools include an alerting service. This creates performance and capacity thresholds on all of the resources that are monitored. If performance drops or capacity approaches its limit, the system generates an alert. Alerts can be forwarded to key personnel by SMS message or email.
Both the server and network monitoring tools are included in the Site24x7 All-in-one plan, which contains all of the monitoring services of the Site24x7 platform. So, there are two options for those who want to monitor Linux servers and networks with the same tool. Site24x7 Infrastructure is available for a 30-day free trial.
