The CA cert file > (/etc/ambari-metrics-monitor/conf/ca.pem) found on every host is generated by > fetching a specific metric collector host's certificate from the truststore. > This certificate file is being used by alert script, service check and even > monitors to talk to collector. > * For example, in a cluster with hosts H1 to H5, let's say there are 2 > collectors - H1 & H2. > * On a node H3, let's say the ca.pem file was constructed using the > certificate for collector H2. > * Service check or metric monitor on H3 will NOT be able to talk to H1 since > it does not have the certificate for that host. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
