this condition.

(o/<IP Address>/SYSTEMDG_CD_02_XXXXXcel01) [SYSTEMDG]

the old (11) version has correctly highlighted the problem, the new (12) does not.

This was verified by navigating to
Cluster Home Page >> Monitoring >> Clusterware Alert Log >> Voting Disk Alert Log Error

Many CRS-1604 and CRS-1605 errors (regarding offline voting disks) in the cluster alert log were not captured for metric Voting Disk Alert Log Error in EM12c


From the metadata:
<Metric NAME="CRSAlert" TYPE="TABLE">
<CategoryProp NAME="CRSVersionCategory" CHOICES="10gR2;11gR1;11gR2"/>

<Label NLSID="alertLog_votingErrStack">Voting Disk Alert Log



From the Agent side collection <cluster_target_name>-cluster.xml file:

<CollectionItem NAME="CRSAlert">


<Condition COLUMN_NAME="votingErrStack"
MESSAGE_NLSID="alertLog_crs_alertmessage" MESSAGE="%votingErrStack% See
%alertLogName% for details." NO_CLEAR_ON_NULL="TRUE" OCCURRENCES="1"
