Installing the Agents in Batches on Linux ECSs

Scenarios

This topic describes how to batch install the Agents on Linux ECSs.

Operation

After binding an elastic IP address to an ECS, install and configure the Agent by following instructions in Installing and Configuring the Agent on a Linux ECS or BMS to ensure that data collection is normal. Use the ECS as a jump server and run scripts in batches to copy, decompress, and install the Agent package and configuration file to other ECSs.

  • The ECSs where the Agent is to be installed in batches must belong to the same VPC.
  • Agents cannot be installed on Windows servers in batches.

Constraints

Some OSs are not supported. For details about which Linux OSs are supported, see What OSs Does the Agent Support?

Prerequisites

  • You have configured an agency by referring to Configuring an Agency by One Click.
  • The IP addresses and password of user root of all ECSs for which the Agent is to be installed have been collected, sorted in the iplist.txt format, and uploaded to the /usr/local directory on the first ECS.

    In the iplist.txt file, each line contains only one IP address in the "IP address,Password of user root" format.

    In the following example, abcd is the password.

    192.168.1.1,abcd
192.168.1.2,abcd

Procedure

  1. Log in to the ECS on which the Agent has been installed as user root.
  2. Run the following command to download and run the batch installation script:
    EU DE:
    cd /usr/local && curl -k -O https://uniagent-eu-de.obs.eu-de.otc.t-systems.com/package/batch_agent_install.sh && bash batch_agent_install.sh -r eu-de -u 0.1.9 -t 2.7.2 -d agent.ces.otc.t-systems.com -o otc.t-systems.com
    EU NL:
    cd /usr/local && curl -k -O https://uniagent-eu-nl.obs.eu-nl.otc.t-systems.com/package/batch_agent_install.sh && bash batch_agent_install.sh -r eu-nl -u 0.1.9 -t 2.7.2 -d agent.ces.otc.t-systems.com -o otc.t-systems.com
  3. Check whether Telescope process starts successfully. is displayed. If so, the installation is successful. Wait for 3 to 5 minutes until the Agent starts collecting monitoring data.
    • After you configure the Agent, its status is still displayed as Not installed on the Server Monitoring page because no monitoring data is reported yet. Wait 3 to 5 minutes and refresh the page.
    • If the Agent status is Running and monitoring is enabled, the Agent has been recognized by Cloud Eye and has started to report fine-grained metric data.
