Description of checks

Antivirus Update Check

This checks that your client's anti-virus pattern file is in sync with the vendor's latest published version. If a discrepancy exists, you'll be alerted. (You'll find supported antivirus programs in the section " How it works")

Why is it important?

Each anti-virus software is as good as its anti-virus pattern file. When you do not have the moct recent file, the probability that your computer might be infected by some virus is growing. Computer viruses can harm and in some cases also destroy all data saved on your computer.

Free Disk Space Check

Check the free disk space on your hard drive. We alert you if the check reveals that the space that remains falls below the amount you specify.

Why is it important?

If you do not have enough free space on your hard drive where your system is installed, your computer starts to slow down and at some point it will stop working.

Drive Space Change Check

Alerts you when the data on the disk have grown unexpectedly in the past 24 hours.

Why is it important?

If in a short period of time free space on your hard drive descreases unexpectedly, this may be an indication of something being amiss with your computer.

Physical Disk Check

This check determines if any SMART (Self-Monitoring, Analysis and Reporting Technology) disks are reporting errors to the operating system and if that is the case, it alerts you. Note that this check works only with disks that use SMART capabilities.

Why is it important?

Hard disks can break just like any other equipment. But if all your data are saved on the hard drive and you do not have a backup copy, you have a problem. That is why it is better to monitor the disk, thus minimizing the risk of unexpected failure.

Hacker Check

This check watches for denied login attempts and alerts you if they exceed a specific threshold.

Why is it important?

Knowing about somebody's attempt to log into your computer is surely very important to all users.

Vulnerability Scanning and Patch Management

This check is searching for all vulnerabilities on your computer and aslo it checks if all security patches are installed.

Why is it important?

Security vulnerabilities are among the most disruptive and damaging types of problem experienced in real-world networks. For you they can mean lost time and potential security breaches. The variety and number of threats continues to increase and it is impractical to manage them without effective tools to automate the process. One of the most effective pro-active steps PC Monitoring can take towards ensuring the minimum level of disruption for you is to make sure that all the relevant patches applicable are installed on your computer.

Event Log Check

The Event Log Check monitors Event Logs and it alerts where the specified information is, or is not, visible in an Event Log entry.

Why is it important?

The Event Logs are repositories of information that have detailed data on the status of the system written to them by applications and Windows components. The Event Log Check monitors the Event Logs and can be configured to query a specific Event Log based on the following indicators - Event ID, Event Type, Event Source and Description.

Windows Service Check

The Windows Services Check monitors Windows Services and alerts the user if a service has stopped.

Why is it important?

Windows systems are underpinned by Windows Services - these services provide crucial functions to users, machines and applications network-wide. If for example the "print spooler" service does not work, you cannot print.


Defragmentation uses the operating system’s disk defragmentation utility to defragment the selected drive.

Why is it important?

After a while, a lot of files on the disk become fragmented - fragmented means that they are not stored in one place as a whole file, but in a few places as smaller fragments. When the computer needs that file, it has to reassemble it. This is the reason behind defragmentation - to maximise disk space and prevent degradation in system performance.

File Size Check

The File Size Check allows you to monitor the size of a group of files, folders (and subfolders) generating an alert when the size of the group is greater or less than the specified threshold.

Why is it important?

When files and folders grow unbounded in size, this can often be an early indicator of a problem on a system, for example a Microsoft SQL Server log file can easily grow to fill the entire disk. Similarly, if a file or folder is below an expected size, this can also indicate a problem, for example if an application has not written to its log file because it failed to run.

Critical Events Check

This check scans all event logs on your computer looking for any critical events during the past 24-hours.

Why is it important?

This is a good catch-all that may show growing problems on a computer/server and highlight the need for you to investigate.

Backup Check

The backup check queries your client’s backup on the days specified to determine the status of the backup.

Why is it important?

To set up the backup schedule is just part of the process. You should ensure that in the event of any problems on your server, there is a backup to restore from.
Depending on the product, the backup information is derived either from the Windows Event Log or from the product's native log files. Have a look at the list of currently supported backup products under How it works

Server Performance Monitoring Check

Server performance monitoring obtains data that may prove useful when diagnosing any problems. It also allows you to build a performance profile of the system which can be used to identify abnormal load.

Why is it important?

When a resource (processor, disk, network interface...) is too busy to keep up with all of its requests, it can become a bottleneck to the system. Such a resource would be thought of as critical to the performance of the system.
Server Performance Monitoring may be used as a form of preventive maintenance to identify any bottlenecks or critical resources on your server before they cause delays. It also helps you to identify other problems and fine-tune or upgrade the system.

WSUS Check

The WSUS check queries the WSUS database for the last synchronisation information and - based on these reports - the number of critical updates that have not yet installed successfully on all computers.

Why is it important?

To set up the WSUS to install the updates on computers and servers is just the first part of the process. The second part is monitoring if the updates have been installed successfully. And our check is doing all of that on your behalf.
