Event Log check
ActiveXperts Network Monitor can read Windows Event logs on local- or remote computers. It can look for specific Event Sources, Categories, Event ID's and so on. It can look for a pattern in the Description of the Event.
It can do advanced filtering in Event Logs; it can look for multiple events in the Event Log, and notify the system administrator if one of the Events occurred in a specific time interval. For instance, as a network administrator, you want an alert if there's a McAfee or Norton virus message in the Application Event Log, but only if the event is posted in the last 30 minutes.
ActiveXperts Network Monitor uses VBScript and WMI for this. It enables you to fully customize Event Log filtering, speeding up performance by checking for more than one event in each cycle.
For more information about the Event Log check, click here.
File check
ActiveXperts Network Monitor can monitor file existence and file size. This is particularly useful in situation where results of scheduled batch jobs needs to be checked. In many organizations, batch jobs run at night and produce logging information; ActiveXperts Network Monitor can check this logging information and analyze it. It can check the existence, or search for patterns.

FTP check
FTP is usually run over TCP using the default port of 21. ActiveXperts Network Monitor can check the availability of FTP sites. If the FTP server is not directly accessible, you can configure ActiveXperts Network Monitor to go through a proxy to access the particular FTP server, even passing credentials for that proxy server (to be able to make use of the proxy). Additionally, you can pass credentials (username and password) to access the actual FTP site if the FTP server requires it.
For more information about the FTP check, click here.
HTTP check
ActiveXperts Network Monitor can check the availability of HTTP and HTTPs sites, on default ports (i.e.: 80 and 443). If the HTTP(s) server is not directly accessible, you can configure ActiveXperts Network Monitor to go through a proxy to access the particular HTTP(s) server, even passing credentials for that proxy server (to be able to make use of the proxy). Additionally, you can pass credentials (username and password) to access the actual HTTP(s) site if required. ActiveXperts Network Monitor supports web site content checking; contents of web sites can be searched for text patterns (including meta tags).

ActiveXperts Network Monitor is also capable of monitoring temperature and water leaks. For a complete overview of all environmental monitoring capabilities in ActiveXperts Network Monitor, click here.
ICMP Ping check
ICMP Ping checks a remote host for availability. Local hosts should normally respond to pings within milliseconds. However, on a very congested network it may take up to 3 seconds or longer to receive an echo packet from the remote host. If the timeout is set too low under these conditions, it will appear that the remote host is not reachable (which is almost the truth). ActiveXperts Network Monitor checks servers for availability by sending ICMP Echo commands and wait for the responds. Reachability doesn't necessarily mean that the remote host is actually functioning beyond its ability to echo packets.
For more information about the ICMP check, click here.
IMAP Mailserver check
ActiveXperts Network Monitor can check IMAP compliant mailservers by establishing a connection on the remote IMAP port (usually port 143) and do a handshake. By handshaking, ActiveXperts Network Monitor can verify that the remote server's IMAP protocol is working well.
For more information about the IMAP check, click here.
LDAP check
ActiveXperts Network Monitor can check LDAP compliant servers by establishing a connection on the remote LDAP port (usually port 389)

Printer check
ActiveXperts Network Monitor checks printers for availability by checking its status. Windows knows a wide range of printer status values, like: 'Running', 'In Test', 'Power Off', 'Offline', 'Power Save', and so on. If the Printer Status is not equal to Running or Power Save, then the printer is considered as malfunctioning.
For more information about the Printer check, click here.
Process check
ActiveXperts Network Monitor enables you to check processes on local- and remote computers; If a process is active, a computer is considered available. If a process is not active, it is not available.
The software can also monitor memory usage of a process. If memory usage of a process exceeds the limit, Network Monitor will generate an error.
For more information about the Process check, click here.
Scheduled Task check
With the Scheduled Task check, people can check if a scheduled task has completed successfully or not.
For more information about the Scheduled Task check, click here.
Service check
Service monitoring involves a probe that returns the status of a service. ActiveXperts Network Monitor monitors services on local- and remote computers by checking if the status equals "Running". If so, the server is running fine, otherwise it's not.
