Hello Syed,
High WaterMark indicates that the percentage of used disk space in the log partition. If you are getting this alert then your application has stored enough amount of logs to reach the configured value (In your case 95%). once it reaches the configured value the system will start deleting the oldest logs by itself, as you can see in the alert it is saying " Purging files".
Though it will automatically start deleting the logs file you can manually delete the logs too in order to get rid of this alert. The best way will be to download the logs and delete from the system. you can follow below steps.
1. Login to RTMT (Real Time Monitoring Tool)
2. Select the required logs that you want to delete. (Mostaly callmanager logs and CTi manager logs consume more space)
3. Select the time window for whcih you want to delete the logs and desired location to download the files
4. on the same window you will see a checkbox " Delete Collected Log Files from Server". check this check box
5. Click on Finish.
Other way is to reduce the Low WaterMark to 10% and High WaterMark to 15% for few minutes (around 30-45 min). this will delete the files automatically. Be informed that this method will loose you the logs file that your organisation may need in future.
Thanks
