Stopping and Starting the Data Collection Utility
The performance data is stored in different data sources on the Citrix
®
 NetScaler
®
appliance. The default data source is /var/log/db/default. You can create up to
32 data sources.
The data collection utility nscollect retrieves data from the NetScaler and updates
the data source. This utility runs automatically when you start the NetScaler. It creates
a database for global counters at /var/log/db/<DataSourceName>. The entity-
specific databases are created based on the entities configured on the NetScaler. A
specific folder is created for each entity type in
/var/log/db/<DataSourceName/EntityNameDB>
Before creating a database for an entity, nscollect allocates a unique number to the
entity and creates the database based on that number. It retrieves all the counters
available for a group. However, there is a limit on the number of different entities that
nscollect can retrieve, as described in the following table.
Table 8-2.
