Firewall recommendations for Performance Monitoring tool
The IBM Storage Scale system uses the following ports for the Performance Monitoring tool to work.
| Port Number | Protocol | Service Name | Components that are involved in communication |
|---|---|---|---|
| 4739 | TCP and UDP | Performance Monitoring tool | Intra-cluster. This port needs to be accessible by all sensor nodes that are sending performance monitoring data. |
| 8123 | TCP | Object Metric collection | Intra-cluster |
| 8124 | TCP | Object Metric collection | Intra-cluster |
| 8125 | UDP | Object Metric collection | Intra-cluster |
| 8126 | TCP | Object Metric collection | Intra-cluster |
| 8127 | TCP | Object Metric collection | Intra-cluster |
| 9085 | TCP | Performance Monitoring Tool | Intra-cluster. This port needs to be open to all nodes where the performance collector is running. This port is used for internal communication between the collectors. |
| 9980 | TCP | Performance Monitoring Tool | Intra-cluster |
Important:
- The 4739 port needs to be open when a collector is installed.
- The 9085 port needs to be open when there are two or more collectors.
- If the port 9980 is closed, accessing the collector remotely, or connecting external tools or even connecting another instance of the GUI remotely, is not possible.
