Troubleshooting checklist¶
The following questions might help you identify the origin of the problem while using Percona Monitoring and Management:
- Are you using the latest PMM version?
- Did you check the known issues section in the Release Notes for that particular PMM release?
- Are you receiving any error messages?
- Do the logs contain any messages about the problem? See Message logs and Trace logs for more information.
- Does the problem occur while configuring PMM, such as:
- Does the problem occur while you configure a specific function?
- Does the problem occur when you perform a particular task?
- Are you using the recommended authentication method?
- Does your system’s firewall allow TCP traffic on the ports used by PMM?
- Have you allocated enough disk space for installing PMM? If not, check the disk allocation space.
- Are you using a Technical Preview feature? Technical Preview features are not production-ready and should only be used in testing environments. For more information, see the relevant Release Notes.
- For installing the PMM client, are you using a package other than a binary package without root permissions?
- Is your PMM Server installed and running with a known IP address accessible from the client node?
- Is the PMM Client installed, and is the node registered with PMM Server?
- Is PMM Client configured correctly and has access to the config file?
- For monitoring MongoDB, do you have adminUserAnyDatabase or superuser role privilege to any database servers you want to monitor?
- For monitoring Amazon RDS using PMM, is there too much latency between PMM Server and the Amazon RDS instance?
- Have you upgraded the PMM Server before you upgraded the PMM Client? If yes, there might be configuration issues, thus leading to failure in the client-server communication, as PMM Server might not be able to identify all the parameters in the configuration.
- Is the PMM Server version higher than or equal to the PMM Client version? Otherwise, there might be configuration issues, thus leading to failure in the client-server communication, as PMM Server might not be able to identify all the parameters in the configuration.
