For testing truststore this link will be useful https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cm_sg_tls_troubleshoot.html#concept_...

And https://www.shellhacks.com/openssl-check-ssl-certificate-expiration-date/ for determining the expiration date.

Assuming you used the same certs, or even if you user different ones; you should be able to click the lock in any SSL based UIs (Ambari, Ranger, Nifi, yarn, grafana, etc) in your browser.  This will show you all details of the certs including expiration dates.
