Viewing Logs on NSX Advanced Load Balancer for a Specific Duration

The log query system on NSX Advanced Load Balancer returns only 10000 logs for a given period since this operation is memory intensive. If the number of logs exceeds 10000, NSX Advanced Load Balancer REST API calls are used to check logs for a specific duration or period.

REST API calls to Retrieve Logs for a Certain Duration

REST API to retrieve event logs for the last day:

https://<cluster_ip>/api/analytics/logs?type=2&duration=86400

REST API to retrieve event logs for the last hour:

https://<cluster_ip>/api/analytics/logs?type=2&duration=3600

The above API calls will retrieve only one page of event logs for that particular duration. To retrieve complete event logs, append ‘&page_size=10000’ to the API query. This will fetch up to 10000 event logs.

API to retrieve event logs for the last day with no paging:

https://<cluster_ip>/api/analytics/logs?type=2&duration=86400&page_size=10000

The log query system is limited to returning at most 10000 logs for a given period, going beyond the threshold value is memory intensive. Workaround is to check logs for a shorter period. If the number of event logs exceeds 10000, use the following APIs.
