@Rizky_Nur_Zhafirah , are you using the Percona Distributions for PostgreSQL or adding pg\_stat\_monitor on top of the community version of PG? What are the settings of PG\_stat\_monitor in your cases, and can you check agents (on the service page) related to the Service - what agents are running? As its very strange if you have other data for queries and no queries. It might be pg\_stat\_statement used in this case. ![image](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/6/62aa3e7770f2945692a309f82455630a5a778ffd.png) ---

Hi Roma, I’m installing Percona Monitoring and Management via [Setting up - Percona Monitoring and Management](https://docs.percona.com/percona-monitoring-and-management/setting-up/index.html) I have both the pg\_stat\_statement and pg\_stat\_monitor in my db. pg\_stat\_statement already exist in my db before i install percona. install and configure pg\_stat\_monitor via this link [Install - pg\_stat\_monitor Documentation](https://docs.percona.com/pg-stat-monitor/install.html) ![Screenshot 2023-09-04 at 10.28.07](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/3/3e068c7f49a9aaa16555a5c6bbe8b8325fb84696.png) ![Screenshot 2023-09-04 at 10.26.56](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/1/17b3680c1e28b4e9819ca49bdbc459873da9e644.png) Is this the agent you mean? ![Screenshot 2023-09-04 at 09.51.50](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/1/189cb50d4211603760ad51d6728e188714742443.png) How can i know if my PMM used pg\_stat\_monitor or pg\_stat\_statement? Thanks in advance ---

@Rizky_Nur_Zhafirah yes, it looks like you have everything installed and running correctly, so this is some PMM-related bug (maybe frontEnd-related) Can you submit a bug to [jira.percona.com](http://jira.percona.com) so our support/engineering team will do a closer look?
