The top-right pane shows information about the FSDB and the selected resource and attribute, including
the total number of resources in the FSDB, the number of attributes for the selected resource, the currently
selected resource and attribute, and the number of data point values collected for the selected metric, when
the first and last values were collected, and its maximum and minimum values. The bottom-right pane
lists each value collected for the selected attribute.
Remove System-Generated Metrics from the FSDB
You can use the FSDBCleaner tool to remove all vCenter Operations Manager system-generated metrics from
the FSDB. When you run FSDBCleaner, it renames the FSDB root directory and writes all metric values, except
the vCenter Operations Manager system-generated metrics, back to a recreated FSDB root directory.
You typically use FSDBCleaner only during an Historical Proof of Concept (HPOC) for
vCenter Operations Manager. In an HPOC, historical data is stored in the vCenter Operations Manager
database and the product analyzes the data to show the alerts and anomalies that would have been generated
if the data had been collected in real time. You use FSDBCleaner during an HPOC to remove the system-
generated metrics so that you can change configuration parameters and rerun the analysis to show how it
changes the results.
Procedure
u
Start FSDBCleaner.
Option Action
Start FSDBCleaner on a Windows
host
Open a command prompt and type vcenter-
ops
\tools\FSDBCleaner\fsdbcleaner.bat.
Start FSDBCleaner on a Linux host
Open an terminal window and type vcenter-
ops
/tools/FSDBCleaner/fsdbcleaner.sh.
For example:
path_fsdbcleaner [-in fsdb_dir_in [-t thread_count ]
n
path_fsdbcleaner is the path to the .bat or .sh file.
n
fsdb_dir_in is the path to the FSDB home directory. If you have more than one FSDB home directory,
you can enter multiple paths, separated by semicolons.
n
thread_count is the number of threads that the tool should spawn to perform the cleaning.
If you do not include the -in option, FSDBCleaner uses the paths defined in the
vCenter Operations Manager configuration and stored in the analytics.properties file. If you do not
include the -t option, FSDBCleaner uses the thread for each CPU on the vCenter Operations Manager
server.
After you enter the command, FSDBCleaner performs the following actions.
n
Renames each specified FSDB root directory to
fsdb_dir_in_cleanerbackup_yyyy_MM_dd_HH_mm_ss .
n
Recreates each FSDB root directory.
n
Creates the specified number of threads to process the data.
n
Retrieves all metrics from the renamed FSDB home directory and saves the filtered metrics to the
fsdb_dir_in directory.
n
Logs its activity in a log file that it creates in
vcenter-ops \FSDBCleaner\logs.
