API Developer Portal (ADP) metrics log not rotating

Products

Issue/Introduction

If the API Developer Portal metrics log is enabled, under certain circumstances the portal_metrics.log file may continue to grow and will not rotate or compress.

Environment

Release:
Component: APIPRD

Cause

After a period of time, typically around 100 days, and under certain circumstances, the portal_metrics.log file may grow to well beyond 1 GB in size without rotating itself or compressing itself.

Resolution

To solve this issue, a user must follow the instructions below:

1. Log into the API Gateway as the root account
2. Create the file "/etc/logrotate.d/metrics" with the following contents, and then save the file.

/opt/SecureSpan/Gateway/node/default/var/logs/portal_metrics.log {
copytruncate
size 100M
rotate 10
compress
missingok
}

• Please note as logrotate is a cron job, a restart of the appliance is not necessary.
• The above steps will ensure that the log file rotates once it reaches 100 MB in size, and compresses the rotated file.
• In the event where it is necessary to immediately force the rotation, the folllowing command can be run: # logrotate --force /etc/logrotate.d/metrics
