This topic describes installing and running VSD for use with VMware GemFire for TAS.
VSD is a free analysis tool and is provided as-is. See VSD System Requirements to view a list of platforms that are known to work with VSD.
VSD is available for download from the VMware GemFire for TAS page on VMware Tanzu Network. It can be installed anywhere, but if Apache Geode is installed in
PRODUCT-DIR, you may wish to install VSD in
PRODUCT-DIR/tools/vsd so it can be conveniently launched from gfsh using the
start vsd command.
Download the VSD archive, usually named something like
pivotal-gemfire-vsd.zip, and unpack it in the directory of your choosing. For this example, assume and VSD was downloaded, unzipped, and installed in
Note: VSD is a 32-bit application. If you are running VSD on a 64-bit machine, you may need to install 32-bit OS libraries to run the application if they are not already installed. On Linux, to find out which libraries are missing, run the following
The VSD tool installation has two subdirectories,
bin. Contains scripts and binaries that can be used to run VSD on a variety of operating systems, including:
lib. The jars and binary libraries needed to run VSD.
To start VSD, you can either execute the scripts directly or you can start VSD through the gfsh interface. To start VSD using the provided scripts, change directories to
PRODUCT-DIR/tools/vsd/bin and the enter the following command at the prompt:
Note: To run VSD on Windows 7 or later, go to the
product-dir/tools/vsd/bin directory. Right-click on
vsd.bat and select Properties. Click Compatibility and set it to Windows XP. Repeat this step for all other executables in the
Linux/Unix, MacOS or Other OS:
To start VSD using
gfsh, start a
gfsh prompt and enter the following command:
VSD displays captured statistics. Those statistics must be copied from the TAS environment where the service instance is to the local environment where VSD is.
There are two ways to acquire the files. Choose one:
After connecting to the service instance with
gfsh export logs command with the
--stats-only as directed in Export gfsh Logs.
Use the BOSH command as specified in View Statistics Files and Logs. The statistics are in
/var/vcap/sys/log/gemfire-server/gemfire/statistics.gfs for servers, and
/var/vcap/sys/log/gemfire-locator/gemfire/statistics.gfs for locators.
You have several options for loading a statistics file into VSD:
Include the name of one or more statistics files on the VSD command line. Example:
vsd STAT-FILE-NAME.gfs ...
Browse for an existing statistics file through Main > Load Data File.
After you load the data file, the VSD main window displays a list of entities for which statistics are available. VSD uses color to distinguish between entities that are still running (shown in green) and those that have stopped (shown in black).
The File > Auto Update is not supported, since the statistics file is static when downloaded.
When opening a .gfs file, statistics are shown in the time zone used on the local computer where VSD is launched. This can made it harder to relate log files to statistics if the logs are from another time zone.
To open a VSD file with the time zone used when generating it, first you need to know in which time zone the .gfs file is created. To obtain this information, use the following command:
strings file.gfs | head
$ strings ObjLoader?-31-03.gfs | head
After you obtain the time zone, modify your local computer to use the time zone used when obtaining statistics in the .gfs file. For example, on a Mac computer, you can first list available time zones:
sudo systemsetup -listtimezones
And then export the specific timezone to your environment:
For example, for Hong Kong:
Then use VSD to open the .gfs file that will now display timestamps from the original time zone.
