Error logging and monitoring of log files – the idea is simple: you store information about application-specific errors in log files, and then a monitoring system periodically parses these files and notifies you when a certain condition occurs.

Database performance monitoring – a number of solution-specific (e.g.

For instance, these are the Apache metrics collected via Acronis Monitoring Service:Īggregated CPU and memory consumption of all Apache processes

Web server performance monitoring – a number solution-specific (e.g.

Service uptime monitoring is a process of checking that the critical services (web server, databases, micro-services, etc.) are running using an agent-based approach (from inside the operating system).

Application level data and notifications can help troubleshoot problems before they impact end users or third-party systems. Also, page load time can differ significantly depending on a region.Īpplication level monitoring uses an agent-based approach to collect and store data from an application stack perspective (application, web server, database).

Full-page load-time monitoring is not as critical as reachability, but as you probably know, today’s customers have very high expectations on how long it takes for a web page to load – so you need to ensure it’s always below your specified threshold.

By creating thresholds, you can always know that the server is not just available, but performs well.

Response time monitoring shows how much time it takes for a web server to respond to a client’s request.

Status code monitoring has the purpose of ensuring the web server responds with a proper HTTP status code (“200” in most cases).If server does not respond – it can be counted as an outage. Reachability monitoring is the most basic check to ensure the server simply responds to external requests.Setup monitoring for all critical URLs and domains used by your application.Constantly check your applications from multiple geographical locations,.

This set of metrics is collected via an external approach (outside the system) from a few geographical locations.

Or, if you want to know if your antivirus software is up and running on your operating system, you can check the availability of the service with a WMI Service sensor or an SNMP Windows Service sensor.External website monitoring, in our case, is a set of metrics that represent how the system performs from an end-user perspective. For example, if you want to check if a web server is available, you send ICMP packets that you monitor with a Ping sensor, but if you want to check if a website is reachable in a specific internet browser, you use an HTTP sensor. Different IT services are reachable via different protocols. You also need to consider the way you define network availability. This means that if you want to monitor the availability of an IT service like a web shop that is hosted on a VMware ESXi host, for example, you also need to monitor all underlying layers including the physical machine (for example, a Dell server), the virtualization platform (here, VMware), the operating system (for example, Windows Server 2019), and the application (for example, a Microsoft IIS web server). In the same way that an IP packet travels from the physical to the application layer, network monitoring needs to cover all aspects from the Ethernet connection to the residing service.
