Optimization: Customize the Linux File Handle Setting for Large Collections

Certain environments may require optimizations to improve performance or to accommodate a large number of data collection policies.

In Linux, a portion of memory is designated for file handles, which is the mechanism used to determine the number of files that can be open at one time. The default value is 1024. For large collection policy environments, this number may need to be increased to 8192 so that the collector does not exceed the open file handle limit. A large environment is characterized as any collector that is collecting from 20 or more subsystems, such as 20+ TSM instances or 20+ unique arrays.

To change the number of file handles, take the following steps.

  1. On the Linux Data Collector server, edit /etc/security/limits.conf and at the end of the file, add these lines.

    root soft nofile 8192
    root hard nofile 8192
  2. Log out and log back in as root to execute the following commands to validate all values have been set to 8192.

    ulimit -n
    ulimit -Hn
    ulimit -Sn
    
  3. Restart the Data Collector.
