Hi experts,
I would like to know if Morpheus can use PostgreSQL for Transactional Database Tier for installation (although I see the document says it supports mySQL-compliant database? And what mechanism do App nodes use to check if a Percona node has failed (for example: App nodes execute a query on a host running MySQL in an interval time like Checks features )?
Thank you!
Morpheus currently only supports MySQL 5.7 and 8.x for the Transactional Database Tier.
Morpheus itself does not monitor the health of the Percona layer of a clustered database. Morpheus returns MySQL level health information in the Administration>Health page of the UI.
Hi @ncelebic
I deployed Morpheus with Distributed PerconaDB for Transactional Database Tier and failover is used in this configuration. So how Morpheus App node know when a database node is healthy/fails? What kind of mechanism does it use to determine that if I follow the Morpheus document installation guide.
Thank you!
Morpheus is using a standard jdbc string (found in /opt/morpheus/conf/application.yml) with configuration for connecting to the db. You’d see connectivity errors in your logs if a node failed.
That is exactly what I need, thank you so much @cbunge
