Export Cluster-Configuration Parameters:

Name Description Default Value
--zip-file-name Required. Filename of the zip file to contain the exported cluster configuration. May also include an absolute or relative path.

export config

Export configuration properties for a member or members.

If you do not specify any parameters, all member configurations will be exported.

Availability: Online. You must be connected in gfsh to a JMX Manager member to use this command.

Syntax:

export config [--members=value(,value)*] [--groups=value(,value)*]
[--dir=value]

Export Config Parameters:

Name Description
--members Name/Id of the member(s) whose configuration will be exported.
--groups Group(s) of members whose configuration will be exported.
--dir Directory to which the exported configuration files will be written.

export data

Export user data from a region to a file or files.

Availability: Online. You must be connected in gfsh to a JMX Manager member to use this command.

Syntax:

To export data from any region, replicated or partitioned, sequentially to a single file, use the --file option:

export data --region=value --member=value --file=value

In this scenario, data from replicated and partitioned regions is exported sequentially to a single file on the specified member.

In the case of partitioned regions, you can speed up the export process by using the --parallel option:

export data  --parallel --region=value --member=value --dir=value

In this scenario, partitioned region data is exported simultaneously on all hosting nodes to directories local to those respective nodes.

  • Parallel export applies only to partitioned regions.

  • The --file and --dir options are mutually exclusive; --file can be used only for serial export, --dir can be used for both serial and parallel exports.

Export Data Parameters:

Name Description
--region Required. Region from which data is to be exported.
‑‑member Required. Name/Id of a member that hosts the region. In a serial export, all data is exported to the specified file on the host where the member is running. In a parallel export, data from a partitioned region partially hosted on this member is exported for each partition to files on the nodes that host those partitions.
--file File to which the exported data is to be written. The file must have an extension of .gfd. Cannot be specified at the same time as --dir, cannot be used with ‑‑parallel.
--dir Directory to which the exported data is to be written. Required if --parallel is true. Cannot be specified at the same time as --file.
--parallel Export local data on each node to a directory on that machine. Available for partitioned regions only.

Example Commands:

export data --region=region2 --file=region2_20121001.gfd --member=server2

Sample Output:

 gfsh>export data --region=region2 --file=region2_20121001.gfd --member=server1
Data succesfully exported from region : region2 to file : C:\PivotalGemFire\
Latest\server1\region2_20121001.gfd on host : 192.0.2.0

export logs

Export logs to a given directory.

All files that have logs in the specified time range will be exported. If no time range is specified, all logs will be exported.

The --dir parameter specifies a local directory to which log files will be written. This is used only when you are exporting logs using an http connection. If executed over http, the zip archive will be saved in the specified directory on the user’s client machine. If not specified, logs are written to the location specified by the user.dir system property. When the command is executed over JMX, logs will be saved as exportedlogs_xxx.zip in the connected locator’s working directory.

Availability: Online. You must be connected in gfsh to a JMX Manager member to use this command.

Syntax:

export logs [--dir=value] [--groups=value(,value)*] [--members=value(,value)*] 
[--log-level=value] [--only-log-level=value] [--merge-log=value] 
[--start-time=value] [--end-time=value] [logs-only(=value)?] 
[--stats-only(=value)?] [--file-size-limit(=value)?]

Export Logs Parameters:

Name Description Default Value
--dir Local directory to which log files will be written when logs are exported using an http connection. Ignored when the command is executed over JMX.  
--groups Group(s) of members whose log files will be exported.  
‑‑members Name/ID of the member(s) whose log files will be exported.  
--log-level Minimum level of log entries to export. Valid values are: OFF, FATAL, ERROR, WARN, INFO, DEBUG, TRACE, and ALL. INFO
--only-log-level Whether to only include only entries that exactly match the --log-level specified. false
‑‑merge‑log Whether to merge logs after exporting to the target directory (deprecated). false
--start-time Log entries that occurred after this time will be exported. Format: yyyy/MM/dd/HH/mm/ss/SSS/z OR yyyy/MM/dd no limit
--end-time Log entries that occurred before this time will be exported. Format: yyyy/MM/dd/HH/mm/ss/SSS/z OR yyyy/MM/dd no limit
--logs-only Whether to export only logs (not statistics) If parameter not specified: false. If parameter specified without a value: true
--stats-only Whether to export only statistics (not logs) If parameter not specified: false. If parameter specified without a value: true
--file-size-limit Limits total unzipped size of the exported files. Specify 0 (zero) for no limit. Value is in megabytes by default or [k,m,g,t] may be specified. If parameter not specified: 100m. If parameter specified without a value: 0

Example commands, showing output:

gfsh>export logs --dir=data/logs
Logs exported to the connected member's file system: /my-locator/data/logs/exportedLogs_1489513007261.zip
gfsh>export logs --dir=data/logs --file-size-limit=1k
Estimated exported logs expanded file size = 95599, file-size-limit = 1024.
To disable exported logs file size check use option "--file-size-limit=0".

gfsh>export logs --dir=data/logs --file-size-limit=99k
Logs exported to the connected member's file system: /my-locator/data/logs/exportedLogs_1489513007261.zip
