HCX - Log rotate functionality is broken for httpd path

Products

• VMware HCX
• VMware Cloud on AWS

Issue/Introduction

Identify and remediate a known issue with HCX log rotation workflow.

Symptoms:
During runtime, "/var/log/httpd" directory may filled up unexpectedly on a given HCX connector or cloud manager.

Cause

In existing HCX systems, the log rotation for httpd is non-functional due to mis-configuration found in the absolute path as described below:

root@hcx [ /etc/logrotate.d ]# cat access-log.conf
/var/log/httpd/access_log {
       copytruncate
       size=50M
       rotate 20
}

Resolution

The issue is fixed in HCX 4.5.0 release.

Workaround:
As a potential WA, we can clean up the content for access.log from below directory:

• Login to HCX admin/root console.
• Go to /var/log/httpd
• Perform below command to cleanup the content from access.log.

> access.log

SAMPLE OUTPUT:

root@vmware-hcx [ ~ ]# cd /var/log/httpd
root@vmware-hcx [ /var/log/httpd ]# ls -l
total 296
-rw-r--r-- 1 root root 23293956 Oct  8 04:06 access.log >>>>>>
-rw-r--r-- 1 root root     3315 Feb 16 05:29 error.log

root@vmware-hcx [ /var/log/httpd ]# > access.log

root@vmware-hcx [ /var/log/httpd ]# ls -l
total 4
-rw-r--r-- 1 root root    0 Feb 16 05:33 access.log >>>>>>>
-rw-r--r-- 1 root root 3315 Feb 16 05:29 error.log

Additional Information

Impact/Risks:

• There will NO operational impact in any migration & network extension functionality.
• It may impact guest customization workflow during vSR Bulk Migration.
• User may observe high usage for "/dev/sda3" or "/dev/sda2" partition in HCX Connector/Cloud manager.

Note: /dev/sda2 or /dev/sda3 partition is used for root directory. Refer to VMware Knowledge Base 90988 for more info.
