Prerequisites for sending performance data to Graphite

Graphite is an open software tool for gathering and graphing performance data from computer systems. Your Graphite server and software must be configured correctly to receive statistical data from Performance Manager.

After you have installed Graphite according to the installation instructions, you need to make the following changes to support statistical data transfer from Performance Manager:

• In the /opt/graphite/conf/carbon.conf file, set the maximum number of files that can be created on the Graphite server per minute to 200: MAX_CREATES_PER_MINUTE = 200

  Depending on the number of clusters in your configuration, and the statistics objects you have selected to send, there may be thousands of new files that need to be created initially. At 200 files per minute it may take 15 or more minutes before all metric files are initially created. After all the unique metric files have been created, this parameter is no longer relevant.

• In the /opt/graphite/conf/storage-schemas.conf file, use the retentions parameter to set the frequency to 5 minutes and the retention period to the number of days that is relevant for your environment.

  The retention period can be as long as what your environment allows, but the frequency value must be set to 5 minutes for at least one retention setting. In the following example, a section is defined for Performance Manager using the pattern parameter, and the values set the initial frequency to 5 minutes and the retention period to 100 days: [OPM]pattern = ^netapp-performance\..*retentions = 5m:100d

  Note: If you change the default vendor tag from "netapp-performance" to something different, you will need to reflect that change in the pattern parameter as well.
