ILIO Disk Space Test

This test reports the space utilization of the NFS datastore. Adequate storage space should be available in the NFS datastore to ensure uninterrupted functioning of the applications in the frontend of the Atlantis ILIO. This test alerts the administrators of potential space contention so that the storage capacity of the datastore can be enhanced before a possible performance deterioration of the server.

Target of the test : An Atlantis ILIO server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the NFS datastore that is to be monitored.

Configurable parameters for the test
Parameter	Description
Test Period	How often should the test be executed.
Host	The IP address of the host for which this test is to be configured.
Port	The port at which the specified Host listens. By default, this is NULL.

Measurements made by the test
Measurement	description	Measurement Unit	Interpretation
Total space	Indicates the total capacity of this NFS datastore.	MB
Used space	Indicates the amount of space that is already utilized in this NFS datastore.	MB	Ideally, the value of this measure should be low. If this value grows close to that of the Total Space measure, then you may consider adding more storage to the datastore, or free up the space in the datastore by deleting unnecessary data.
Free space	Indicates the amount of space that is currently available for use in this NFS datastore.	MB	A high value is desired for this measure. A sharp/consistent decrease in the value of this measure is an indication for the administrators to add more free space to the datastore before the datastore runs out of free space. Sometimes, the value of this measure may be 0 which indicates that the datastore is currently unavailable. In such cases, the VMs that are currently using that datastore could be rendered inaccessible to users.
Percentage of space used	Indicates the percentage of space that is already utilized in this NFS datastore.	Percent	A value close to 100% indicates that the datastore is currently running out of space.
