Increase the multicell log collector timeout value in VCD

Products

• VMware Cloud Director
• VMware Telco Cloud Platform

Issue/Introduction

• When collecting logs using the multicell log collector, a log collection timeout occurs if the number or size of the log files specified in the log4j configuration has been increased beyond default values.

Environment

• VCD 10.x
• TCP: 3, 4.x, 4.0.1, 5.x, 5.0. 5.0.1, 5.0.2

Cause

• The default log collection timeout is set to 7 minutes based on the standard log4j allocation (10 files at 10 MB each).
• Increasing the size or volume of log files causes the log bundle generation process to exceed this standard timeout window.

Resolution

1. Take a backup or snapshot of all VCD appliance cells before modifying configuration files.
2. Establish an SSH session to the primary VCD appliance.
3. Open /opt/vmware/vcloud-director/bin/vmware-vcd-multi-cell-log-collector in a text editor.
4. Locate the timeout definition parameter: readonly TIMEOUT_IN_MINUTES=7
5. Update the value to allow additional time for log collection (for example, 20 minutes): readonly TIMEOUT_IN_MINUTES=20
6. Save the file and repeat Steps 2 through 5 on all remaining VCD cells.
7. Restart the VCD service across all cells to apply the changes: service vmware-vcd restart
