Linux server monitor
This chapter describes how to add and modify the Linux application monitor, and helps you view the
monitor report.
Linux
Linux is a popular open source operating system that has multiple release versions. Monitoring Linux is
necessary because the operating performance of a Linux server affects network applications on the
system.
APM can monitor the Linux release versions of Ubuntu, RedHat, SUSE, and Center OS.
Adding a Linux application monitor
APM monitors the Linux application through CLI or SNMP. When you add the application monitor for
Linux, make sure the following requirements are satisfied:
• Telnet, SSH, or SNMP must be enabled and configured on Linux. For information about enabling
Telnet, SSH, or SNMP on Linux, see the Linux configuration guide
.
• The target host must be added to the IMC Platform. For information about adding a host to the IMC
Platform, see IMC Base Platform Administrator Guide for the chapter on resource management.
• To monitor the Linux application through CLI, correctly configure the Telnet or SSH username and
password on the IMC Platform. APM obtains the Telnet or SSH username and password of the
Linux host from the IMC Platform. The Telnet or SSH user must have the administrator privilege.
• To monitor the Linux application through SNMP, correctly configure SNMP parameters on the IMC
Platform. APM obtains the SNMP community strings for Linux from the IMC Platform.
To add a Linux application monitor:
1. Click the Resource tab.
2. Enter the Add Application page in one of the following ways:
Select Application Manager > Add Application from the navigation tree.
The page displays all application types that can be monitored by APM.
Select Application Manager > Application Monitor from the navigation tree, and click Add on
the application monitor list page.
3. Click Linux of the Linux Server Monitor class.
The page for adding a Linux application monitor appears.
4. Configure the following parameters for the application monitor:
Name—Enter the application monitor name, which must be unique in APM. HP recommends
that you use the Application name_host IP address format to name the application monitor.
Description—Enter a description for the application monitor to aid maintenance.
IP Address—Click Select and select the host on which the Linux application will be monitored
in the Select Devices window.
