Issue/Introduction

After importing a template for Isilon devices and creating profiles in Operator Console, no metrics are collected for these devices.

Checking the RESTMON probe logs, the following is observed:

2026-02-05 08:23:17 INFO  ProfileHandler - Start processProfile  for ALL the entities of Isilon_Test interval: 60 seconds
2026-02-05 08:23:17 INFO  DataCollector - Start collectAndStoreAllData for profile [Isilon_Test]
2026-02-05 08:23:19 ERROR DataCollector - Error executing url: https://<IsilonIPAddress>:3033/platform/3/cluster/config
2026-02-05 08:23:19 ERROR DataCollector - java.util.concurrent.ExecutionException: java.net.ConnectException: Connection refused: no further information: <IsilonIPAddress>:3033

Environment

• UIM 23.4.x
• RESTMON probe 5.0.0+

Cause

Communication attempts to the Isilon device on the specified port are failing.  The Connection refused message indicates that communication attempts are being blocked outside of UIM.  There are multiple possible reasons for these communication failures.

• Isilon profile configured with the wrong port
• Network firewalls prevent communications
• Server firewall prevents communications
• Isilon port isn't open for communications

Resolution

To resolve the communication failure, do the following:

1. Confirm the right port is configured in the Isilon profile.
   • The default port used by the profile is 3033.  Confirm that the Isilon device is also configured to listen on this port.  You can find information on the UIM Isilon profile configuration in the documentation here:
     Dell EMC Isilon
2. Confirm that firewalls are configured to allow communications on the configured port.
   • Both the network and server firewalls should be confirmed to allow the port configured on the Isilon device and in the UIM profile.  This port must be opened for communications by the firewalls.
3. Confirm that the Dell EMC Isilon configuration matches what is configured in the probe.
   • As noted in step 1, the default port used in the UIM profile is 3033.  If these do not match, the communications will fail.
