DESCRIPTION
The dsosd directory file maps container names to local filesystem path names. The directory is formatted as JSON and has a separate section for each dsosd instance. The format of the file is as follows:
{ <server-id> : { <container-name> : <container-path>, <container-name> : <container-path>, . . . }, <server-id> : { <container-name> : <container-path>, <container-name> : <container-path>, . . . }, . . . }
By default the <server-id> is the hostname, but this can be overridden with the DSOSD_SERVER_ID environment variable specified when starting dsosd.
The <container name> is the path parameter provided to the sos_container_open() function. The <container-path> is the filesysystem path to the SOS container.
EXAMPLE
{ "orion-01" : { "ldms-current" : "/storage/orion-01/sos/ldms-current", "ldms-january" : "/storage/orion-01/sos/january/ldms-current" }, "orion-02" : { "ldms-current" : "/storage/orion-02/sos/ldms-current", "ldms-january" : "/storage/orion-02/sos/january/ldms-current" }, "orion-03" : { "ldms-current" : "/storage/orion-03/sos/ldms-current", "ldms-january" : "/storage/orion-03/sos/january/ldms-current" }, "orion-04" : { "ldms-current" : "/storage/orion-04/sos/ldms-current", "ldms-january" : "/storage/orion-04/sos/january/ldms-current" } }
ENVIRONMENT
The following environment variables may be used to affect the
configuration of the dsosd daemon.
- DSOSD_DIRECTORY The path to a JSON formatted file that maps container
names to local filesystem paths.
- DSOSD_SERVER_ID A logical name for this dsosd instance. If not
specified, the hostname (as determined by gethostname) will be used. This name is used to determine which sections of the directory file apply to this dsosd instance.
