Hi, i already use prometheus and mysql exporter with percona app plugin for grafana. I don’t want another prometheus shipped with PMM but I want to use qan too, so it is possible to install only QAN part of PMM ? how i can do this? Thank you everyone ---

Hi [Antonio Falzarano](https://percona.vanillacommunities.com/profile/x/x/39559) , About PMM Server: It is possible, you have two ways: [LIST=1] [_]install everything manually. it is really not a trivial task. you can find components on [url][Percona Monitoring and Management](https://www.percona.com/doc/percona-monitoring-and-management/architecture.html%5B/url%5D) page. repositories of all components are located on GitHub - [url][https://github.com/percona/[/url]](https://github.com/percona/%5B/url%5D) useful PMM Server setup information can be found in Ansible scripts [url][https://github.com/percona/pmm-server/blob/master/playbook-init.yml[/url]](https://github.com/percona/pmm-server/blob/master/playbook-init.yml%5B/url%5D) [url][https://github.com/percona/pmm-server/blob/master/playbook-install.yml[/url]](https://github.com/percona/pmm-server/blob/master/playbook-install.yml%5B/url%5D) It is the totally unsupported way! [_]you can start PMM Server as usual (as docker container) and use only QAN functionality (see below). [/LIST]About PMM Client: pmm-admin tool supports the possibility to add QAN and Metrics independently. So it is possible to add only QAN monitoring without exporters. just use {code}sudo pmm-admin add mysql:queries{code} instead of {code}sudo pmm-admin add mysql{code} anyway, keep in mind that percona exporters have SSL and Authentification support, this is not supported in original prometheus exporters (see [url][https://www.robustperception.io/prometheus-security-authentication-authorization-and-encryption/[/url]](https://www.robustperception.io/prometheus-security-authentication-authorization-and-encryption/%5B/url%5D)) also, percona/mysqld\_exporter smarter that original, we have three different targets for high, medium and low resolution metrics, because internal database performance debug requires high-resolution for some metrics. ---

Hi [Mykola](https://percona.vanillacommunities.com/profile/x/x/30783) , thank you , i look into this informations. About different resolution metrics there is some documentation that can i read, to understand differences with original mysql\_exporter? ---

All Percona code is publically available, so if you want you can diff changes between [percona/mysqld\_exporter](https://github.com/percona/mysqld_exporter) and [prometheus/mysqld\_exporter](https://github.com/prometheus/mysqld_exporter/) repositories. Anyway, his part is not well documented yet, so I created a ticket - [PMM-1162](https://jira.percona.com/browse/PMM-1162), it is publicly visible and you can register in our Jira and add self to the watcher list or vote for this ticket or write any suggestions 🙂 ---

Thank you Mykola, it seems that PMM-1162 is not a public ticket, i miss something? ![photoid=49495](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/2/2ead2f5e7acdc9b6cbdd80917d9b615ce625bb82.png) ---

Hi [Antonio Falzarano](https://percona.vanillacommunities.com/profile/x/x/39559) , I’ve just configured the security settings for that issue, it should now load correctly.
