Installing LoadsMetric

LoadsMetric is a load collection and analysis tool. It obtains machine metric information from the Node Exporter, analyzes and processes the information, and reports the generated cluster load and balancing data to Prometheus. Install LoadsMetric on the server1 node only.

1. Optional: Create the hadoop user. Skip this step if this user has already existed.

   useradd hadoop

2. Create /home/hadoop/loadsmetric-software to use it as the installation directory. Obtain the dependency package from Table 3, upload it to the created directory, and extract the package.

   mkdir -p /home/hadoop/loadsmetric-software
   cd /home/hadoop/loadsmetric-software
   unzip BoostKit-loadsmetric-1.0.0-aarch64.zip

3. Check whether the following files are generated after the extraction:

   workers
   loadsmetric_configfile.properties
   loadsmetric_deploy.sh
   loadsmetric-server-1.0.0-SNAPSHOT-aarch64.tar.gz
   boostkit-yarn-schedule-load-evolution-1.0.0.jar
   LoadsMetric.json

4. Change workers to the compute node list.
   1. Open the workers file.

      vi workers

   2. Press i to enter the insert mode and modify the file.

      agent1
      agent2
      agent3

   3. Press Esc, type :wq!, and press Enter to save the file and exit.
5. Modify loadsmetric_configfile.properties. For details about the configuration items, see References.
   1. Open the loadsmetric_configfile.properties file.

      vi loadsmetric_configfile.properties

   2. Press i to enter the insert mode and add the following content to the file:

   3. Press Esc, type :wq!, and press Enter to save the file and exit.
6. Perform the installation.

   cd /home/hadoop/loadsmetric-software
   sh loadsmetric_deploy.sh install

7. Check whether the installation is successful.
   If the command output contains the installation directory, the installation is successful.

   1	ll /home/hadoop/loadsmetric-install/loadsmetric-server

   

8. Starting LoadsMetric

   sh loadsmetric_deploy.sh start

9. Run the jps command to check whether LoadsMetric is started. If the LoadsMetricApplication process is displayed, the startup is successful.

   

The LoadsMetric service can be installed, uninstalled, started, and stopped. It allows starting and stopping Prometheus, Node Exporter, and Grafana with one click. For details about basic O&M commands, see Using LoadsMetric.
