Retention period for log analytics custom table

[gortegaMS]

When querying the ngsa and loderunner logs, the data only seemed to go back 30 days. Is that intentional? It is also possible that I was querying the data incorrectly.

Yes, we encountered that data retention is set to 30 day only.

Now the question is if 30 days will provide us enough data to make the correct Alert Threshold adjustment, since if we need to go back and query older data and check why we selected that particular value, data will not be there and we will not have a point of reference.
