Chapter 6. Performance Tuning

After installing Resource Manager, you can optimize its performance by:

• Packing the ZODB

• Editing archived event data storage settings

• Running ZenTune

• Setting memory caching values

• Increasing maximum file descriptors

• Increasing RRD performance

• Configuring the messaging system

6.1. Packing the ZODB

The Zope Object Database (ZODB) keeps records of all transactions performed. As these records accumulate,

the database file grows over time.

To keep the database running efficiently, Resource Manager runs a weekly cron job to regularly remove old

transactions. You also can initiate this process at any time; as the zenoss user, use the following command:

$ZENHOME/bin/zenossdbpack

Note

You should run this command only on the system master (not on remote collectors).

6.2. Editing Archived Event Data Storage Settings

You can edit the default settings for archived event data to improve Resource Manager performance. Changing

these settings to values that are reasonable for your implementation will prevent the Zenoss DataStore from

filling up your hard drive. An extremely large database also can have a negative impact on performance.

To change the settings for length of time Resource Manager archives event data:

1. Select Advanced, and then select Events from the left panel.

The Event Configuration page appears.

2. Adjust values as desired for these configuration settings:

• Delete Archived Events Older Than (days) - By default, this is set to 90 days. Accepted values are

between 1 and 1000 days.

• Event Time Purge Interval (days) - By default, this is set to 7 days. Accepted values are between 1

and 250 days.

3. Click Save to save your changes.

6.3. ZenTune

The ZenTune "tuning advisor" analyzes your system configuration and makes recommendations for better per-

formance. The feature is implemented through the ZenPacks.zenoss.AutoTune ZenPack.

6.3.1. Using ZenTune

To access ZenTune, select Advanced > Tuning from the Resource Manager interface.
