Hi Rafael,

Are you running ISE on VMWare or ISE appliance?

I guess your monitoring node requires more space. You may need to regularly backup / clear the logs from the MnT node

On any node that has the Monitoring persona enabled, 30% of the VM disk space is allocated for log storage. For a Monitoring node with 600 GB VM disk space, 180 GB is allocated for log storage. A deployment with 100,000 user endpoints generates 2 GB of logs approximately per day. In this case, you can store 30 days of logs in the Monitoring node, after which you must transfer the old data to a repository and purge it from the Monitoring database. For extra log storage, you can increase the VM disk space. For every 100 GB of disk space that you add, you get 30 GB more for log storage. Depending on your requirements, you can increase the VM disk size up to a maximum of 600 GB or 180 GB log storage. The 30% disk space allotment is applicable only for fresh installations. If you upgrade to 1.1.x, a maximum of 150 GB is allocated for the MnT node irrespective of the VM disk size.
