Standard Checks

This section contains the complete information about checks available in standard version of Network Eagle.

Available check types

Network Eagle Monitor offers its users a large set of various checks starting from the simplest ones and finishing with a script check that can be configured to monitor almost everything in Microsoft Networks if combined with the WMI technology,. The following types of checks are available now:

• Ping Check
  A ping is a very simple way to check if a computer and the network between the computer and the Network Eagle machine is functional. It sends an Internet Control Message Protocol (ICMP) echo packet to the computer and listens for an echo reply packet.
• TCP Port Check
  This check establishes a basic connection to another computer over TCP/IP. Connecting to the specified network service (Mail, HTTP, FTP, Telnet servers and so on) over TCP is the simplest way to check the availability of this service.
• FTP Location Check
  A File Transfer Protocol Server Check tries to connect to the specified FTP server and to check if the specified FTP path on the FTP server is available using the FTP protocol. The path can point either to a directory or to a file on the FTP server.
• HTTP Location Check
  An HTTP Location Check tries to connect to the specified HTTP server and to check if the specified HTTP path on the HTTP server is available using the HTTP protocol. The path can point either to a directory or to a file on the HTTP server.
• Disk Space Check
  This check monitors disk space on a disk or on a network share with various conditions and notifies the user in case a failure occurs. For example, you can be notified if disk space on some critical share on your network is less then 100 Mb.

• External Command Check
  This check can run and monitor the exit code of an external command or a batch script. You can either easily develop your own basic plug-ins to use them with this check or use any console utility which can report its status using the application exit code.
• Database Check
  This check monitors a database. It supports database connections via ODBC and a direct connection to the MS SQL server. This check can either test only if it is possible to connect to the selected database or execute a custom SQL query and perform some basic checks in the result.
  
• Script Check
  This check can execute a user-defined script (usually, VB Script or Java Script), where the user can define his own script code to perform some checks or even operations. It is up to the user to decide what situation is bad and what situation is good. You should specify its startup function. This function will be called each time the check starts and the result of this function will be the result of the check. If it returns false, null, undefined, etc., the check is considered failed, otherwise the check is considered successful.
• Process Check
  This check can monitor a process either on the local machine or on a remote one on the local area network (LAN). It tests if the process is alive aliveness using its name or/and its id.
• Event Log Check
  This check can monitor messages in the Windows Event Log either on the local machine or on a remote one. You can use more then ten criteria and regular expressions in message description to define what message or set of messages the check should wait for.
• Windows service Check
  This check can monitor the state of an Windows service on either local or remote (LAN) computer. It tests if Windows Service is alive using its name.
• Directory Check
  This check can monitor specified directory for the changes. It watches directory size and/or number of directory files and can execute alerts if user-defined criteria is satisfied. For example, you can configure this check to be notified if your log directory exceeds 10 GB size.
