Hi,
After upgrading Hyperic HQ from 4.5 to 4.6.6, one of my custom sql measurement plugins has started recording incorrect metrics, as shown in the following screenshot (shows the last 8 hours of metrics):
"Enabled Nodes" metric is a simple count query in a table with only 8 records (that should return 1 or 0). The "Since Last Run" metric calculates the number of seconds between the current date and a date field in the database (for this example, should return less than 5mins or start ramping up if the date field isn't being updated). I've repeatedly run the queries directly in the database and never get any incorrect results like the one's above.
Before the upgrade, the measurements were always exactly what they should have been. Within half an hour of upgrading the first incorrect alert was triggered.
Both server and agent are running on RHEL server 5.8. Tried restarting both agent and server, as well as redeploying the plugin and recreating the resource. Database is oracle 11g, have tried both ojdbc5 and ojdbc6 versions of the oracle JDBC driver.
I've tried changing the log levels to see where in the process the incorrect metrics are appearing but no luck so far.
Regards,
Jamie.
