Table 'performance_schema.global_status' doesn't exist about my2collector

[meob]

Global_status table is contained information_schema and not in performance_schema.
The same problem is in the my2.sql.
Try to use an editor and replace all performance_schema.global_status with information_schema.global_status. Good luck

MySQL 5.7 and 8.0 use performance_schema while older MySQL versions and MariaDB use information_schema. my2.sql code tries to use the right schema for the running version but it is not bullet proof. For Grafana dashboards I have 2 different versions... maybe I'll do the same for the my2 collector. Which fork and version are You using?

Same issue here.

Same issue here.
Which MySQL version are You using?
Can You send me the result of version() function and of SHOW VARIABLES command?

in variable dashboard (MyVar2) replace with :

select concat('MySQL version: ',version(), ' Created at: ', date_format(min(create_time),'%Y-%m-%d %T') ,
' Started at: ', date_format(date_sub(now(), INTERVAL variable_value second),'%Y-%m-%d %T')) info
from information_schema.tables,information_schema.global_status
where variable_name='UPTIME'
group by variable_value

Global_status table is contained information_schema and not in performance_schema.

The same problem is in the my2.sql.
Try to use an editor and replace all performance_schema.global_status with information_schema.global_status. Good luck

Grafana dashboards for MySQL and MariaDB are different

I'm adding extra information to deal with the missing table.

First check where the table actually is. It may be at information_schema or performance_schema.
run this query to know where:
select TABLE_SCHEMA , TABLE_NAME from information_schema.TABLES t where TABLE_NAME ='global_status'

Also you may enable performance schema at my.conf or mysqld.conf
[mysqld]
performance_schema=ON
