Subject [jira] Updated: (GERONIMO-3541) monitoring plugin: collecting agent needs to use a database to store the snapshots instead of xml
Date Tue, 23 Oct 2007 14:43:51 GMT

     [ https://issues.apache.org/jira/browse/GERONIMO-3541?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Viet Hung Nguyen updated GERONIMO-3541:
---------------------------------------

    Attachment: geronimo-3541.patch

I have changed the db structure to be as the following:

Statistics
-mbeanid       (F.K. refs MBeans.id)
-snapshotid    (F.K. refs Snapshots.id)
-statsValue
-statsName

MBeans
-id            (P.K.)
-mbeanName

Snapshots
-id            (P.K.)
-snapshot_time
-snapshot_date

Erik, I do not think that putting statistics names in a CSV list in a db is a good practice.
And in this case, I will not be able to save a statsValue for each statsName if I did that.
There would not be a way of mapping it. However, I have broken up the table into multiple
pieces as we have discussed before.

If someone could take a look at this, it will be great, because it is a significant part that
needs to be established before we can move on to other things.

> The DB needs to be populated with snapshot statistics. Also, the functions used to query
snapshots needs to be migrated from reading from XML files to a DB.
