Metric extension details and history
Publishing the Metric Extension
When your metric is working as expected, you are ready to publish it so that the metric extension is available for
deployment by any EM user. Note that a deployed metric extension in Deployable Draft status is visible to all users
who can view the target. They can even edit metric settings, just as they can for any other metric. Publishing a metric
extension accomplishes nothing more than providing the ability to deploy this metric extension (or to be more
precise, this specific version of the metric extension) to other targets.
You can publish a metric extension from the Metric Extensions home page by choosing Actions
➤
Publish
Metric Extension. The status changes to Published, and the metric extension becomes available to any EM user.
Note that Published metrics can also be included in Monitoring Templates, another important difference from
Deployable Draft status.
Now imagine that the metric is working well, but after some time you realize it would be helpful to have
additional information about the session. You want to see the highest number of open cursors, and not just how close
the open-cursors count is to the limit. Having the SID, username, client machine, client OS user, and client program
available in the metric itself would greatly assist in troubleshooting alerts generated by your new metric extension.
Creating a New Version of Metric Extension
Let's improve the metric extension that you just created. From the Metric Extensions home page, select the
current version and choose Actions
➤
Create Next Version. Then change the general properties reflecting the
changes in the description.
