The host(s) on which this operation should be performed are selected using the standard selection mechanism
(see 

 above). Optional arguments can be any number of the 

 listed at the beginning

of this section.

host-data-source-list

 [

<host-selectors>

=

<host selector value>

...]

List the data sources that can be recorded for a host.

Select  the  host(s)  on  which  to  perform  this  operation  by  using  the  standard  selection  mechanism  (see 

). Optional arguments can be any number of the 

 listed at the beginning of this section.

If no parameters to select hosts are given, the operation will be performed on all hosts.

Data sources have two parameters — 

standard

 and 

enabled

 — which can be seen by the output of this

command. If a data source has 

enabled

 set to 

true

, then the metrics are currently being recorded to the

performance  database.  If  a  data  source  has 

standard

  set  to 

true

,  then  the  metrics  are  recorded  to  the

performance database by default (and so, 

enabled

 will also be set to 

true

 for this data source). If a data source

has 

standard

 set to 

false

, then the metrics are not recorded to the performance database by default (and

so, 

enabled

 will also be set to 

false

 for this data source).

To start recording data source metrics to the performance database, run the host-data-source-record command.
This will set 

enabled

 to 

true

. To stop, run the host-data-source-forget. This will set 

enabled

 to 

false

.

host-data-source-record

  data-source=

<name_description_of_data-source>

  [

<host-selectors>

=

<host

selector value>

...]

Record the specified data source for a host.

This operation writes the information from the data source to the persistent performance metrics database of
the specified host(s). For performance reasons, this database is distinct from the normal agent database.

Select  the  host(s)  on  which  to  perform  this  operation  by  using  the  standard  selection  mechanism  (see 

). Optional arguments can be any number of the 

 listed at the beginning of this section.

If no parameters to select hosts are given, the operation will be performed on all hosts.

host-data-source-forget

  data-source=

<name_description_of_data-source>

  [

<host-selectors>

=

<host

selector value>

...]

Stop recording the specified data source for a host and forget all of the recorded data.

Select  the  host(s)  on  which  to  perform  this  operation  by  using  the  standard  selection  mechanism  (see 

). Optional arguments can be any number of the 

 listed at the beginning of this section.

If no parameters to select hosts are given, the operation will be performed on all hosts.

host-data-source-query

  data-source=

<name_description_of_data-source>

  [

<host-selectors>

=

<host

selector value>

...]

Display the specified data source for a host.

Select  the  host(s)  on  which  to  perform  this  operation  by  using  the  standard  selection  mechanism  (see 

). Optional arguments can be any number of the 

 listed at the beginning of this section.

If no parameters to select hosts are given, the operation will be performed on all hosts.
