  • 0 Ratings

Symptoms

vRealize Log Insight agent is unable to pull down latest configuration from the vRealize Log Insight cluster or push events to the cluster.

You experience these symptoms:
  • Under Administration > Agents, the guest operating system reports a Last Active time of greater than 5 minutes
  • You have recently upgraded from vRealize Log Insight 3.6 or earlier to 4.0 or later.
  • In the liagent_YYYY-MM-DD_##.log file, on the operating system running the vRealize Log Insight, you see entries similar to:

    2017-01-30 17:20:13.511401 0x00000078 <trace> CFApiTransport:128 | Connecting to server vrli-cluster-01.sfo01.rainpole.local:9000
    2017-01-30 17:20:13.527058 0x00000078 <error> CurlConnection:844 | CurlConnection::Connect transport error: SSL connect error
    2017-01-30 17:20:13.527058 0x00000078 <trace> CFApiTransport:106 | DoConnectJob [Postpone connection by 1 sec]


  • The liagent.ini file contains a line:

    port=9000

  • All of the ssl related properties within the liagent.ini file are either not present or commented out with a preceding ; character.

Cause

This issue occurs because the default ssl property value is set to yes in vRealize Log Insight 4.0. The agent attempts to make an SSL connection on an incorrect port.

Resolution

This is a known issue affecting vRealize Log Insight 4.0.

Currently, there is no resolution.

To work around this issue, you must remove the line that specifies the port in liagent.ini file in vRealize Log Insight agent machine:
  1. Log in to vRealize Log Insight agent machine with administrative permissions.
  2. Use your preferred method to navigate to the liagent.ini file:

    • On Microsoft platforms, the default location for the liagent.ini file is %ProgramData%\VMware\Log Insight Agent.
    • On POSIX systems, the default location for the liagent.ini file is /etc/liagent.ini.

  3. Use your preferred method to save a copy of the liagent.ini file.
  4. Edit the liagent.ini file using a text editor.
  5. Remove this line from the file:

    port=9000

  6. Save the file.

Additional Information

The default port value behavior for the vRealize Log Insight agent is dependent on the values of ssl and proto properties.

Below are the default port values:
  • If the ssl property is set to no and the proto property is set to cfapi, then the default port property value will be 9000.
  • If the ssl property is set to yes and the proto property is set to cfapi, then the default port property value will be 9543.
  • If the ssl property is set to no and the proto property is set to syslog, then the default port property value will be 514.
  • If the ssl property is set to yes and the proto property is set to syslog, then the default port property value will be 6514.
