Diagnostics

Object Cache Pro’s diagnostics provide a deep insight into its overall state.

You can access the diagnostics through:

• Tools > Site Health > Info
• WP CLI: wp redis diagnostics
• The Query Monitor plugin

The dashboard widget will also show some diagnostic information and errors, but not as many as the options above.

#Eviction Policy

To avoid Redis running out of memory and your site going down, it’s recommended to set Redis’ maxmemory-policy configuration option to allkeys-lru or allkeys-lfu.

If this causes too much CPU usage in your particular set up, you can use a reasonable maxttl for your setup. See configuration options.
