Linux Monitors
The Linux Server Manager monitors check specific elements of any licensed Linux system and loaded into Network Server Suite via the Device Manager. The Linux Monitors work in the same way as the Windows Monitors, in that rules are created, criteria specified and actions set.
The following monitors are available for the specific monitoring of Linux Servers.
Linux Logical Volume Monitor
The Linux Logical Volume Monitor checks the status of Logical Groups, Logical Volumes and Physical Volumes of the Linux system. Alerts are raised if the criteria exists, does not exist or triggers a pre-defined value. The current status of the Logical Groups, Logical Volumes and Physical Volumes can be displayed when setting the rule criteria. A test facility is also available that allows the pre-testing of the rule with the current criteria settings and make amendments as required based on the received results.
Script Monitor
The Linux Script Monitor runs custom Linux scripts and commands and checks the output against Regular Expressions.
File & Folder Monitor
The Linux File & Folder Monitor checks Linux files and folders for existence, non-existence or for any physical changes. Alerts are raised if any of the selected conditions are proven or for any changes in selected folders and/or files.
For example, when a new file is created in a folder or when the size of a file changes. This is useful for ensuring that critical files are not deleted.
Log File Monitor
The Linux Log File Monitor checks the standard Linux Event Logs. New events in the log can be filtered and alerts raised accordingly. Rule criteria use Regular Expressions to filter information. Regular expressions allow you to select specific strings from a set of character strings.
CPU, Filesystem & Memory Monitor
The Linux CPU, Filesystem & Memory Monitor gives administrators the ability to monitor the CPU, Filesystem and Memory statistical data of any Linux system loaded into the Central Configuration Manager.
System Monitor
The Linux System Monitor checks system load average over a pre-defined time period. Alert raised if load exceeds, equals or falls short of user-defined criteria.
The System Monitor can also monitor the system up-time of Linux device.
Process Monitor
The Linux Process Monitor checks Linux system processes by a series of processor measurements, such as CPU Usage %, Cumulative CPU Time and so on. Alerts are raised when a process triggers a pre-defined value.
Ping Monitor
The Linux Ping Monitor checks the status of remote devices by sending an ICMP ping. The number of ping attempts per device and success percentage can be specified. An alert is raised if success percentage falls below threshold.
Linux Actions
Only three actions are available when creating Linux Monitor rules:
See Adding Rule Actions for more information on these three action types.
