Recently, we received a PMM client update request. After updating the agents on all monitored nodes, the system has stopped functioning as expected. Specifically, the inbuilt dashboards are no longer displaying the required data correctly, although everything was working fine prior to the update. To troubleshoot this issue, I have already: - Reconfigured both the PMM server and the PMM clients. - Followed the official documentation and troubleshooting steps available online. - Verified the `pmm-server` status and `inventory list`, both of which indicate that all components are running properly. Despite these efforts, the issue persists ---

Hi @Sumit_sarova 1. can you share what version of PMM Server and PMM client are you using? 2. Is it MySQL, PostgreSQL or MongoDB? 3. Can you run pmm-admin summary and check for errors in logs 4. Can you call https://PMM\_SERVER\_URL/logs.zip and check errors there? 5. From which version to which you have upgraded? 6. Did you upgrade only PMM Cleints or PMM Server as well? ---

Your mysqld\_exporter is trying to ping the MySQL instance on 127.0.0.1:3306. Can you check manually if you are able to telnet 127.0.0.1 3306 or manually connect to MySQL using 127.0.0.1 on 3306? Also, check the netstat -tnlp or bind address of MySQL. Please note that your initial PMM client for MySQL was configured for the address 10.110.128.196:3306. ---

Hi @Sumit_sarova Could you please delete the service account related to that server, re-register the agent, and try once? Hope you’re using the same version of the PMM server and client. PMM server: 3.2.0 PMM Client: 3.2.0 ![image](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/3X/b/b/bbf449680a520447eb70ed37433ffa965892bba6.png) ---

after investigation we found pmm-client version 3.2.0 is not compatible with pmm-server 3.2.0, so after downgrading pmm-client 3.1.0 it is working as expected, I suggest the community do the same procedure if anyone faces the same issue. sudo apt install pmm-client=3.1.0-7.noble ![working](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/3X/b/e/be59d8b88ef80ae064e94a04d807c4ccdc558bb9.png) ---
