It is STRONGLY recommended that you enable InnoDB in any %s version greater than 5.5.3.

Depending on the number of logins and use of spine data collector, %s will need many connections. The calculation for spine is: total_connections = total_processes * (total_threads + script_servers + 1), then you must leave headroom for user connections, which will change depending on the number of concurrent login accounts.

If using the Cacti Performance Booster and choosing a memory storage engine, you have to be careful to flush your Performance Booster buffer before the system runs out of memory table space. This is done two ways, first reducing the size of your output column to just the right size. This column is in the tables poller_output, and poller_output_boost. The second thing you can do is allocate more memory to memory tables. We have arbitrarily chosen a recommended value of 10%% of system memory, but if you are using SSD disk drives, or have a smaller system, you may ignore this recommendation or choose a different storage engine. You may see the expected consumption of the Performance Booster tables under Console -> System Utilities -> View Boost Status.

When using InnoDB storage it is important to keep your table spaces separate. This makes managing the tables simpler for long time users of %s. If you are running with this currently off, you can migrate to the per file storage by enabling the feature, and then running an alter statement on all InnoDB tables.

InnoDB will hold as much tables and indexes in system memory as is possible. Therefore, you should make the innodb_buffer_pool large enough to hold as much of the tables and index in memory. Checking the size of the /var/lib/mysql/cacti directory will help in determining this value. We are recommending 25%% of your systems total memory, but your requirements will vary depending on your systems size. If you database is very large or remote, you can consider increasing this size. If remote, it can by as high as 80% of the systems memory. However, cautions must be taken to reduce the swapiness of the system, or to remove swap to keep the system from swapping.

Setting this value to 2 means that you will flush all transactions every second rather than at commit. This allows %s to perform writing less often.
|
|
As of %s %s, the you can control how often %s flushes transactions to disk. The default is 1 second, but in high I/O systems setting to a value greater than 1 can allow disk I/O to be more sequential

%s will divide the innodb_buffer_pool into memory regions to improve performance for versions of MariaDB less than 10.5. The max value is 64, but should not exceed more than the number of CPU cores/threads. When your innodb_buffer_pool is less than 1GB, you should use the pool size divided by 128MB. Continue to use this equation up to the max the number of CPU cores or 64.
