The status page provides a quick view of what VDBs are configured, what servers are attached to them, and their current health status, along with what clients are connected to them.
For each VDB, the data sources will be shown, the last HB time an update about that server was received, the current qps, connections and if configured, replica lag is.
For the clients, the pin option allows a given client to be saved and always viewed on the status dashboard. This is to allow the current state of clients that only periodically to be viewed. If the pinned option is not set, then clients not seen for over five minutes will disappear from the status view.
Note: A client MAY show as red if it is using connection pooling, despite traffic being active from the client.
If in the VDB configuration Cluster manager via cache is enabled and cluster cache has been used (i.e. Hazelcast or Redis working in cluster mode), the cluster information table will appear, showing cache type, status, list of nodes, partitions owned by each node and the cache uptime.
When the collapsed menu button is clicked, there should be displayed additional actions showed in the image below. Below are some actions and details what each of the button is used for:
- Terminate Process: It will terminate and restart proxy process - if the proxy is mange by central manager. Otherwise, if you have an independent proxy running, proxy process will be terminated (not restart).
- Clear Credentials Properties: It will clear the credentials properties cache for a specific proxy. It's usefully when the SQL driven authentication is enabled.
- Heap dump: It will make a proxy heap dump, which will be available in Logs tab.
- Stack trace: It will make a proxy stack trace, which will be available in Logs tab.
- Packet Capturing: You can initiate a timed packet capture on specific Proxy nodes. This includes limiting duration, total number of files, and the size limit for the capture. Port 8087 and 8443 will be filtered out of the capture automatically.
