Description

In the Remote Host Configuration section, click Add to configure a host for monitoring. You can configure multiple

Host Details

Host Names/File Path

Enter the host name of the server in either of the following options:

  • Single host name or IP address.
  • If you want to use the same configuration for multiple hosts, enter a comma-separated list of host names or IP addresses with common credentials.
  • If you want to use the same configuration for a large number of hosts, you can configure the remote hosts from a file (.txt, .csv). Enter the absolute path to the file that includes a list of host names or IP addresses. For example, the file path can be /opt/bmc/BMCPatrolAgent/Patrol3/log/Prouction_lpars or $PATROL_HOME/log/Prouction_lpars
    • The file must contain a list of comma-separated host names or IP addresses info.png(with or without publish hostnames) that have common credentials. 
    • The file must be located on the host which is running the PATROL Agent. BMC PATROL default account must have read permission on the directory where the file is located. The _ConfigStatus attribute indicates errors related to the input file.
  • A combination of all the earlier options.
Information

You can add a publish hostname to represent the host with different a hostname or if the Fully Qualified Domain name of the remote host cannot be retrieved. The publish hostname can be added in <hostname>;<publish_hostname> format. This format can be used in any of the above options.

Note: If you modify the file, restart the BMC PATROL Agent to apply the changes.

Port Number

Enter the remote host SSH port number. By default, the port number is set to 22.

User Name

Enter the username to connect to the remote host. If this field is left blank the KM uses PATROL Agent default account credentials to connect to the remote host. Password based authentication will be used for verifying the credentials.

Authentication

Select the authentication mode to add remote host:

  • Password-Based
  • Key-Based

Password-Based Authentication

Password

Enter the common credentials of the hosts added in the Host Names/File Path field.

Key Based Authentication

Public Key File Path

Enter the entire path of the public key file.

Private Key File Path

Enter the entire pathname of the private key file.

Passphrase

Enter the passphrase to access public and private keys.

Sudo Configuration

Sudo Execution Mode (For Linux only)

 Select any of the following Sudo execution mode for the remote host:

  • Sudo is Not Configured -  To not use the Sudo utility
  • Use Sudo With Password - To use the Sudo utility by providing the PATROL user password to the Sudo command. 
  • Use Sudo Without Password - To use the Sudo utility without passing the PATROL user password to the Sudo command.
    To use this option, make sure that you have configured a remote host monitoring account.
To configure the Sudo on a Linux Computer
  1. Download the sudo utility from: http://www.sudo.ws/sudo/download.html.
  2. Open the sudoers file with a text editor.
    Generally, this file is located in the /etc directory.
  3. To use the Without password option, enter the following line: 
    userName ALL = (ALL)
    NOPASSWD: ALL    .
    Note: The userName variable represents the user for which the PATROL user is configured.
  4. Comment Defaults requiretty as #Defaults requiretty.
  5. Save the sudoers file.
  6. Log off from the monitored server.

Important:

To make sure that Sudo is correctly configured on the remote server host, run the following command from the PATROL Agent server and verify the output: 

ssh <monitoring username>@<remote server hostname> 'sudo -S -p "%%" stat -t /opt' 

Sudo Command Password

Enter the Sudo command password.

Configure Monitor Types

Monitoring Options

Select the type of monitoring.

  • Standard Monitoring: This option enables monitoring of CPU, Memory, Network, and File System monitor types only.
  • Advanced Monitoring: This option allows you to select and configure individual monitor types. These configurations need to be enabled explicitly.

Advanced monitoring configuration

Monitor type selection/configuration

In this section, select the monitor types that you want to monitor in the remote host.

CPU configuration

CPU

Select this checkbox to enable CPU monitoring.

CPU Annotation

Enable Annotation

Select this checkbox to enable annotation. Annotation refers to additional details about specific processes that consume the most CPU resources.

CPU Threshold for Annotation (%)

Enter the CPU threshold (in percent) to generate the annotation. The annotation displays the top 10 processes consuming the highest CPU resources on the system. The annotations are generated based on the Utilization (Utilization) parameter. For more information about the parameter, see CPU (NUK_CPU).

The default value for the CPU threshold is 90%.

Warning

Important

In BHOM, you can create an alarm policy based on the metric value of the Utilization parameter.

Warning

Important

To generate annotations based on the parameter, you must enable the BHOM Annotation feature.

Memory configuration

Memory

Select this checkbox to enable Memory monitoring.

Memory Annotation

Enable Annotation

Select this checkbox to enable annotation. Annotation refers to additional details about specific processes that consume the most memory resources.

Memory Threshold for Annotation (%)

Enter the memory threshold (in percent) to generate the annotation. The annotation displays the top 10 processes consuming the highest memory resources on the system. The annotations are generated based on the Percent of memory pages used (includes buffers-cache) (Utilization) parameter. For more information about the parameter, see Memory (NUK_Memory).

The default value for the memory threshold is 90%.

Warning

Important

In BHOM, you can create an alarm policy based on the metric value of the Percent of memory pages used (UsedPercent) parameter.

Warning

Important

To generate annotations based on the parameter, you must enable the BHOM Annotation feature.
