DTStat statistics

The following statistics appear in the

statistic.sts

file. If you convert that file to an ASCII, comma-delimited file using the

dtstat -s

option, the heading labels may appear slightly different.

Category

Statistic

Description

Date/Time
Stamp

The date and time that the snapshot was taken. This is the date and time that each
statistic was logged. By default, these are generated once a second, as long as there
are statistics being generated. If mirroring/replication is idle, then DTStat will be idle
as well.

System
Allocator

The number of bytes currently allocated to the system pagefile

IQ Allocator

The number of bytes currently allocated to the intermediate queue

Security

Logins

The number of successful login attempts

Failed
Logins

The number of failed login attempts

Kernel

Source
State

0

—Source is not running

1

—Source is running without the replication driver

2

—Source is running with the replication driver

Target
State

0

—Target is not running

1

—Target is running

Start Time

Date and time stamp indicating when the Storage Mirroring daemon was loaded

RepOps
Generated

The number of replication operations generated by the file system driver. An op is a
file system operation. Storage Mirroring replicates data by sending the file system
operations across the network to the target. RepOpsGenerated indicates the
number of file system operations that have been generated by replication.

RepBytes
Generated

The number of replication bytes generated by the file system driver. This is the
number of bytes generated during replication. In other words, this is roughly the
amount of traffic being sent across the network that is generated by replication. It
does not take into account TCP/IP overhead (headers and such).

MirOps
Generated

The number of mirror operations transmitted to the target. Mirroring is completed
by transmitting the file system operations necessary to generate the files on the
target. This statistic indicates the number of file system operations that were
transmitted during the initial mirror. It will continue to increase until the mirror is
complete. Any subsequent remirrors will reset this field to zero and increment from
there.

MirBytes
Generated

The number of mirror bytes transmitted to the target. This is the number of bytes
generated during mirroring. In other words, this is roughly the amount of traffic being
sent across the network that is generated by the mirror. It does not take into
account TCP/IP overhead (headers and such). Again, any subsequent remirror will
reset this field to zero and increment from there.

Failed
Mirror
Count

The number of mirror operations that failed due to an error reading the file from the
disk

FailedRep
Count

The number of replication operations that failed due to an error reading the file from
the disk

ActFail
Count

The number of activation code failures when loading the source or target. Activation
codes can be bad for reasons such as: expiration of evaluation codes, duplicate codes,
incorrect codes, etc.
