Deploying monitor_collector

This section describes how to deploy the monitor_collector cluster monitoring service on the Meta node.

1. Obtain the binary file and configuration file from the compilation server (Meta node in this document).

   mkdir -p /var/log/3fs 
   mkdir -p /opt/3fs/{bin,etc} 
   rsync -avz meta:/home/3fs/build/bin/monitor_collector_main /opt/3fs/bin/ 
   rsync -avz meta:/home/3fs/configs/monitor_collector_main.toml /opt/3fs/etc/ 
   rsync -avz meta:/home/3fs/deploy/systemd/monitor_collector_main.service /usr/lib/systemd/system

2. Modify the monitor_collector_main.toml configuration file.
   1. Open /opt/3fs/etc/monitor_collector_main.toml.

      vim /opt/3fs/etc/monitor_collector_main.toml 

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

      ... 
      [server.base.groups.listener] 
      filter_list = ['enp1s0f0np0'] # Enter the RDMA NIC name.
      listen_port = 10000 
      listen_queue_depth = 4096 
      rdma_listen_ethernet = true 
      reuse_port = false 
      ...
      # Find the following configuration and modify it.
      [server.monitor_collector.reporter.clickhouse] 
      db = '3fs' 
      host = '127.0.0.1' 
      passwd = 'clickhouse123' 
      port = '9123' 
      user = 'default'

   3. Press Esc to exit the insert mode. Type :wq! and press Enter to save the file and exit.
3. Start the monitor_collector service.

   systemctl start monitor_collector_main

4. Check the status of monitor_collector.

   systemctl status monitor_collector_main 

   

5. Check the port status.

   ss -tuln

   Command output:

   # Netid      State       Recv-Q      Send-Q            Local Address:Port            Peer Address:Port     Process 
   # ... 
   # tcp        LISTEN      0           4096             192.168.65.10:10000                0.0.0.0:* 
   # ...

   

   • If 192.168.65.10:10000 is displayed, do not configure 127.0.0.1:10000, so as to avoid incorrect port connection from other services.
   • If multiple ports 10000 are found, check whether the filter_list configuration item is set in the monitor_collector_main.toml file.
