Issue/Introduction

After deploying the cluster probe, we see it failing to connect to secondary nodes with this error:
 

Apr 22 12:23:41:420 [12592] cluster: (updateGroupConf) - Session Send failed to ip/host=x.x.x.x
Apr 22 12:24:41:675 [14376] cluster: (updateGroupConf) - Session Send failed to ip/host=x.x.x.x 
Apr 22 12:25:41:690 [8860] cluster: (updateGroupConf) - Session Send failed to ip/host=x.x.x.x
 

Cause

In this case, the issue was being caused by a timeout with the network connection between the two nodes.

Environment

UIM version 8.51 
cluster probe version 3.50

**This information is generally applicable to all versions of UIM / Cluster probe

Resolution

Raise the communication_timeout value within the probe configuration to allow the probe additional time to make the connection.

> deactivate the probe
> open the raw configuration for the probe in Infrastructure Manager or Admin Console
> in the <setup> section section, raise the communication_timeout key
> activate the probe

 

 

The recommendation is to raise the value by 20 with each test. Repeat if necessary.
If you continue to see the issue after reaching around a value of a 100, please open a ticket with Support for continued investigation.
It is not recommended to raise the value too high, as this can bog down the network with continuous traffic.
