Some devices are dropped using the monitor plugin. cacti 1.2

Hello, I am new using cacti, I recently installed version 1.2.1 of cacti.
I detail the information of my installed programs

I have the following message in the MariaDB documentation.
innodb_buffer_pool_instances 8> = 16 MariaDB will divide innodb_buffer_pool into memory regions to improve performance. The maximum value is 64. When innodb_buffer_pool is less than 1GB, you should use the pool size divided by 128MB. Keep using this equation based on a maximum of 64.

I feel that something does not quite set it up.
I hope you can help me.

Your title and content of post do not seem to mesh (to me). The MySQL issue you described is because Cacti recommends you raise the number of regions being used in the my.cnf (or cacti.cnf depending on how you configured things). That has little to do with the monitor plugin.

Thank you very much for your response, sorry for not having explained very well, but I have 73 devices and there are some that the cacti plugin monitor shows fallen, but if you ping within the network respond. Check the cactus settings several times and everything is fine.

Everything was fine when I only had 35 devices, but as the devices increased, I decided to change the cmd.php poller to the spine, because I read it was faster.

Thank you
