The Linux Monitoring lets you monitor and manage your Linux environment. It monitors the availability of your servers, which includes the following elements:

Monitored Objects

Application classes

 Description

Data collectionDCMManages and monitors data collection.

CPU and Kernel

CPU

Monitors processor statistics such as percentages of CPU utilization, CPU idle time, CPU time spent on user and system activities.

SMP

Monitors basic CPU utilization statistics for multiple processors on a computer

KERNEL

Provides information such as Kernel Memory Allocation (KMA) statistics, i-node usage, and Kernel usage of system resources

Overall system health

HEALTH AT A GLANCE

Monitors the Overall CPU usage, filesystem usage, and virtual memory of the system

Memory

MEMORY

Monitors memory activities and reports detailed memory utilization.

SWAP

Monitors virtual memory and provides the memory utilization for the entire system and for each swap area

Networks

NETWORK

Monitors the network for information about interfaces, addresses, protocols, and traffic.

Network file systems

NFS

Provides you with an abstract view of the entire filesystem, regardless of the various systems' architectures and operating systems

Processes

PROCESS

Displays statistics on process switches, run queues, messaging, and semaphores and allows you to list zombie processes and change process priorities.

PROCESS_PRESENCE

Monitors specified processes running on your system.

Scheduling tasks

SCHEDULER

Schedules processes and establishes monitoring blackout periods in your environment

Reviewing security

SECURITY

Provides listings of the group and password files and shows the failed logins

Health of SNMP

SNMPHealth

Monitors whether the SNMP Master Agent and subagent are running, lists configuration information, and provides diagnostic tests with which you can troubleshoot problems.

Users

USERS

Monitors the resource consumption of individual users as well as the number of users and sessions that run on the system

Filesystems

FILESYSTEM

Monitors the filesystems mounted on a system for information such as disk space, i-nodes, mount and unmounts file systems.

Disks

DISKS

Monitors the disk drives that are mounted on a system

Remote hosts

REMOTE_HOSTS

Monitors remote hosts running Secure Shell (SSH) protocol version 2 (SSH2) using the PSL collection method.

REMOTE_MONITORING

Acts as a container KM and hosts the instances of all remote hosts.

Linux Virtualization

LVIRT

Monitors the virtual machines statistics such as

  • CPU utilization of the virtual machine
  • Configuration information such as maximum available memory and number of virtual CPUs assigned to the virtual machine
  • State of the virtual machine
  • Disk usage information
  • Network usage information
  • No labels
