Stopping Traffic into Each Canister
Before upgrading, traffic must be stopped into the processing pipeline of each Discover Canister.
About this task
After traffic stops and the Data Collector completes a run, the upgrade can be performed.
Note: When traffic is stopped
to the Canister pipeline, data is spooled to disk. Each processing
server should have sufficient disk space to queue for 30 minutes.
If all available disk space is consumed, hits that are forwarded to
the Canister are dropped.
For each Processing Server
Procedure
- Open the following URL in your web browser:
http://<Machine_Name>:19000
where:
<Machine_Name>
is the name or IP address of the Processing Server - The Discover Search Server web interface is displayed.
- In the Governor pane at the lower left, click Drain STC. This step forces the Discover pipeline to start queuing data and instructs the Short Term Canister to write out any active sessions to long-term storage.
- Repeat the steps for each Processing Server before you check for Data Collection completion.
Results
Before you begin the upgrade, verify that the Data Collector completed its run.
