Flushing Caches#

Squirro uses caches to speed up common actions, such as queries. This section shows how to flush these caches when necessary.

Introduction#

In rare circumstances, the Squirro caches may become stale. If this occurs, contact Squirro Support for resolution.

Caches#

There are two different caches managed in Redis. They are stored in different databases (see Accessing Servers for background):

  • db7: the query cache, which stores the full query responses. Updating this cache can be disabled by using the update_cache option in the item query API call.

  • db9: the generic HTTP cache which is used to cache internal calls to the various internal web services.

Flush Cache (Squirro 2.4.6 and Newer)#

To flush the caches, restart redis-server-cache:

systemctl restart redis-server-cache
