Configure collectd to Store Host Performance Data

You can use collectd to receive and store performance data from multiple hosts.

About this task

The collectd network plugin configuration is disabled by default. Use the StarlingX network_servers service-parameter to enable and configure it for use on one or more hosts and ports.

Note

If you are planning to use a remote InfluxDB instance as a receiver, the default port is 25826. Overriding this port must be done on the host where an InfluxDB instance is running.

If a port is not defined using the service parameter, the default port from InfluxDB will be automatically set but will not be visible in the service parameter list. Therefore, skipping port definition is discouraged.

Add collectd configuration parameters

Procedure

  1. List the currently configured service parameters:

    ~(keystone_admin)]$ system service-parameter-list
    
    +-------------+------------+---------+-----------------+-------+-------------+----------+
    | uuid        | service    | section | name            | value | personality | resource |
    +-------------+------------+---------+-----------------+-------+-------------+----------+
    | 17d024d1... | horizon    | auth    | lockout_retries | 3     | None        | None     |
    | bf3cefdb... | horizon    | auth    | lockout_seconds | 300   | None        | None     |
    | d574763b... | radosgw    | config  | fs_size_mb      | 25    | None        | None     |
    | 03dd07ba... | http       | config  | http_port       | 8080  | None        | None     |
    | 1bbdb378... | http       | config  | https_port      | 8443  | None        | None     |
    | 8dc30732... | kubernetes | config  | pod_max_pids    | 10000 | None        | None     |
    | 3346bec7... | radosgw    | config  | service_enabled | false | None        | None     |
    +-------------+------------+---------+-----------------+-------+-------------+----------+
    

    Note that collectd is not listed in the section column.

  2. Add the platform collectd network_servers service parameter using the following command format:

    system service-parameter-add platform collectd network_servers=<host1>:<port1>,<host2>:<port2>,...,<hostN>:<portN>
    

    where:

    host

    A host to receive and store data on. IPv6 addresses are also supported. For example:

    network_servers=[2001:0db8:85a3:08d3:1319:8a2e:0370:7344]:8080,[ff18::efc0:4a42]:25826
    
    port

    A port on <host> to send data to. The port must be an integer between 1 and 65535.

    Multiple host/port combinations can be specified as a comma-separated list. For example:

    ~(keystone_admin)]$ system service-parameter-add platform collectd network_servers=controller:25826,192.168.1.123:25826
    
    +-------------+--------------------------------------+
    | Property    | Value                                |
    +-------------+--------------------------------------+
    | uuid        | 69553a96-1f73-4e7c-8fd0-1235c0aa1771 |
    | service     | platform                             |
    | section     | collectd                             |
    | name        | network_servers                      |
    | value       | controller:25826,192.168.1.123:25826 |
    | personality | None                                 |
    | resource    | None                                 |
    +-------------+--------------------------------------+
    
  3. Optional step: To persist the new parameter, run the following command:

    ~(keystone_admin)]$ system service-parameter-apply platform
    
  4. List the currently configured service parameters again and confirm your change:

    ~(keystone_admin)]$ system service-parameter-list
    
    +-------------+------------+----------+-----------------+--------------------------+-------------+----------+
    | uuid        | service    | section  | name            | value                    | personality | resource |

Example

  1. Change the parameter.

    This example replaces port 25826 on host 192.168.1.123 with port 25000 on host 192.168.1.200.

    ~(keystone_admin)]$ system service-parameter-modify platform collectd network_servers=192.168.1.200:25000,influxdb-host:25826
    
    +-------------+-----------------------------------------+
    | Property    | Value                                   |

      Swact to controller-0.

      ~(keystone_admin)]$ system host-swact controller-1
      

      This step can take up to 10 minutes.

    This step can take up to 10 minutes.

Remove collectd configuration parameters

Use the system service-parameter-delete command to remove an existing collectd configuration.

Example

  1. List the currently configured service parameters and locate the appropriate UUID:

    ~(keystone_admin)]$ system service-parameter-list
    
    +--------------------------------------+------------+----------+-----------------+--------------------------+-------------+----------+
    | uuid                                 | service    | section  | name            | value                    | personality | resource |

    +--------------------------------------+------------+----------+-----------------+--------------------------+-------------+----------+
    

    In this example, the UUID for collectd is 69553a96-1f73-4e7c-8fd0-1235c0aa1771.

  2. Remove the parameter:

    ~(keystone_admin)]$ system service-parameter-delete 69553a96-1f73-4e7c-8fd0-1235c0aa1771
    
  3. List the currently configured service parameters:

    +-------------+------------+---------+-----------------+-------+-------------+----------+
    

    Note that collectd is no longer listed in the section column.

  4. (AIO-SX only) Lock and unlock the controller to have your changes take effect:

    ~(keystone_admin)]$ system host-lock controller-0
    ~(keystone_admin)]$ system host-unlock controller-0
    
  5. (AIO-DX or Standard systems) Lock and unlock controller-1.

    ~(keystone_admin)]$ system host-lock controller-1
    ~(keystone_admin)]$ system host-unlock controller-1
    

    This step can take up to 10 minutes.

    1. Make controller-1 active.

      ~(keystone_admin)]$ system host-swact controller-0
      
      1. Log in to controller-1.

      2. Lock and unlock controller-0.

        ~(keystone_admin)]$ system host-lock controller-1
        ~(keystone_admin)]$ system host-unlock controller-1
        

        This step can take up to 10 minutes.

    2. Set controller-0 as the active controller.

      Swact to controller-0.

      ~(keystone_admin)]$ system host-swact controller-1
      

      This step can take up to 10 minutes.
