Help Introduction What is a Monitor

What is a Monitor?

Any resource whose performance needs to be tracked is considered as a monitor in Site24x7. A monitor can be a website, a server, a network device, an application or any component in your IT infrastructure that needs monitoring. Site24x7 presents these resources as monitors in the web client and examines the availability and various performance trends of your endpoints, internet resources, servers, network resources, cloud resources, VMs, applications and more from a single console. 

For example, a server monitor tracks critical metrics like CPU, memory, disk utilization, network utilization, event logs, and process metrics to avoid any performance degradation issues. Likewise, a website monitor tracks metrics like throughput and response time with detailed first byte time, last byte time, DNS resolution time, and SSL handshake time split-up. 

Site24x7 licensing works based on the type of monitor. Monitors are classified as:

You can view monitors based on basic and advanced in the Site24x7 web client. Learn more.

Some of the key facets of a Site24x7 Monitors are listed below:

You can monitor any internet facing resource using our agentless monitors. Monitoring is enabled from 110+ locations globally or behind the firewall using On-Premises Poller

You can monitor local URLs, ports, processes using the server monitoring agents. In this case, each Server is considered as a monitor. You can also monitor all resources in that server using the same Site24x7 server agent.

We typically charge for a host and IP combination. For example, a server is charged as one basic monitor, which monitors servers, processes, syslogs, other resources on the server including URL, port, NFS, files, directories and more at no additional cost. Each monitor comes with one plugin on the server. Likewise, for VMware, we charge by virtual machines. 

A server monitor also includes monitoring applications or services using our ready-to-use plugin integrations or your own plugin that you can build. We do not charge you extra for this. Each plugin comes with 25 custom metrics, by default. Also, one plugin is free/server. Additional plugin on server will be accounted as one additional basic monitor.

Some Microsoft apps supported out-of-the box are charged extra. Microsoft IIS is considered as a basic monitor. Microsoft Sharepoint, Office 365, Microsoft SQL, Microsoft Biztalk, Microsoft Exchange, Microsoft Failover Cluster, Microsoft AD are licensed as advanced monitors.

Licensing for network monitoring is purely based on the number of interfaces that are monitored. It is mandatory to have at least one active interface in order to monitor a device. While ten performance counters per device can be monitored for free, every additional ten is counted as one interface.

Each AWS instance is considered as a monitor.

For internet services monitoring, you can monitor from up to 16 locations. We use a predictable polling from a location logic so that graphs are uniform and intelligible. Other vendors use a round-robin methodology which gives too many spikes between polls because of latency differences due to different geographical conditions. Different sets of 16 locations can be selected from our list of 110+ geographical locations to monitor various internet monitors.

The EliteEnterprise and Enterprise Plus Web Plans support monitoring from 16 locations.

The amount of uploadable logs varies with the licensing plan for Site24x7 AppLogs.

Licensing example: Say you have to monitor two physical servers running your website and its back-end. In total, you would need three basic monitors. Two monitors for viewing detailed CPU, memory, disk performance information of your critical servers and one monitor for checking the website's domain itself.
