Veritas InfoScale™ Operations Manager 8.0.2 Release Notes

About space estimation for data logs

In Veritas InfoScale Operations Manager, historical performance data of various resources is collected in a fixed-size binary file. The older data is overwritten as new data arrives in a circular round robin array. The number of metrics, frequency of data insertion, number of objects, and the roll-up databases affect the size of binary file. The higher resolution data is compressed to a lower resolution data.

For more information on performance metering statistics, see the Veritas InfoScale Operations Manager Management Server User Guide.

Table: Space estimation for data logs describes the space estimation for data logs for the various resources. For estimation purposes, the data in the Number of resources column is according to the standard environment. The metrics collected column represents the number of metrics collected for each resource. For example, in case of DMP paths, the total number of metrics collected is four: bytes read, bytes written, read average, and write average.

Data logs for host, volume, disk, file system, path, and initiator are stored on the managed host. The data logs for virtualization server, virtual machine, path, and initiator are stored on the Control Host. For storage array (port, adapter, and enclosure), data log for 1 day is stored on the discovery host, where as all the other logs are stored on Management Server.

Table: Space estimation for data logs for Windows hosts lists the space estimation for data logs for host, file system, volume, and disk on Windows platform.
