Hi liuqian , is this occurring on all your nodes or just one? Which specific exporter are you running, is this mysqld_exporter, mongodb_exporter, proxysql_exporter, or node_exporter?
We have a data collection script called pmm-info.sh which if you wouldn’t mind executing in your environment, that will help us assist you further. Please see this blog post for details:
The essential steps are:
wget https://raw.githubusercontent.com/Percona-QA/percona-qa/master/pmm-info.sh vi pmm-info.sh sh ./pmm-info.sh
Thank you,kill mysqld_exporter release memory
