Threshold values for NTDS Object performance counter (Active Directory)
Hi,
I want to know threshold values for NTDS Object counters like:
DS Client Binds Per Sec
DS Client Name Translation per Sec
DS Directory Reads per Sec
DS Directory Searches per sec
DS Directory Writes per sec
DS Monitor List Size
DS Name Cache Hit Rate
DS Notify Queue Size
LSA Reads
LSA Searches
LSA Writes
NSPI Reads
NSPI Searches
NSPI Writes
...
...
...
Is there any threshold values are defined for these counters?
Or how can anyone define threshold values for above counters?

1. Have not seen any specific values yet. My guess is that it is individual for you system and you should start from baseline values.
2. Not directly the response to your question, but very close is a measure of risk and health. Unfortunaltely this is for some customers, see http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=19464

Hello, I hope this information will be helpful.
NTDS:
Counter Description
DRA Inbound Bytes Compressed (Between Sites, After Compression)/sec The compressed
size (in bytes) of compressed replication data inbound from directory system agents
(DSAs) in other sites (per second).
DRA Inbound Bytes Compressed (Between Sites, Before Compression)/sec The
uncompressed size (in bytes) of compressed replication data inbound from DSAs in
other sites (per second).
DRA Inbound Bytes Not Compressed (Within Site)/sec The uncompressed size (in bytes)
of replication data that was not compressed at the source - that is, inbound from
other DSAs in the same site (per second).
DRA Inbound Bytes Total/sec The total number of bytes (per second) received through
replication. It is the sum of the number of bytes of uncompressed data (never
compressed) and compressed data (after compression).
DRA Inbound Full Sync Objects Remaining The number of objects remaining until the
full synchronization process is completed.
DRA Inbound Objects/sec The number of objects received (per second) through inbound
replication from replication partners.
DRA Inbound Objects Applied/sec The number of objects received (per second) from
replication partners and applied by the local directory service. This
counter
excludes changes that are received but not applied (for example, when the update is
already made). This counter indicates how many replication updates are occurring on
the server as a result of changes generated on other servers.
DRA Inbound Objects Filtered/sec The number of objects received (per second) from
replication partners that contained no updates that needed to be applied.
DRA Inbound Object Updates Remaining in Packet The number of
object updates
received in the current directory replication update packet that have not yet been
applied to the local server. This counter tells you whether the monitored server is
receiving changes, but is taking a long time applying them to the database.
DRA Inbound Properties Applied/sec The number of changes (per second) to
object
properties that are applied through inbound replication as a result of
reconciliation logic.
DRA Inbound Properties Filtered/sec The number of changes (per second) to
object
properties received during the replication that are already made.
DRA Inbound Properties Total/sec The total number of changes (per second) to
object
properties received from replication partners.
DRA Inbound Values (DNs only)/sec The number of
values of object properties
received (per second) from replication partners in which the values are
for object
properties that belong to distinguished names. This number includes objects that
reference other objects. Values for distinguished names, such as group or
distribution list memberships, are more expensive to apply than other kinds of
values because a group or distribution list
object can include hundreds or
thousands of members. In contrast, a simple object might have only one or two
attributes. A high number from this counter might explain why inbound changes are
slow to be applied to the database.
DRA Inbound Values Total/sec The total number of
values of object properties
received (per second) from replication partners. Each inbound object has one or
more properties, and each property has zero or more values. A value of zero
indicates that the property is to be removed.
DRA Outbound Bytes Compressed (Between Sites, After Compression)/sec The compressed
size (in bytes) of compressed replication data that is outbound to DSAs in other
sites (per second).
DRA Outbound Bytes Compressed (Between Sites, Before Compression)/sec The
uncompressed size (in bytes) of compressed replication data outbound to DSAs in
other sites (per second).
DRA Outbound Bytes Not Compressed (Within Site)/sec The uncompressed size (in
bytes) of outbound replication data that was not compressed - that is, outbound to
DSAs in the same site - per second.
DRA Outbound Bytes Total/sec The total number of bytes sent per second. It is the
sum of the number of bytes of uncompressed data (never compressed) and compressed
data (after compression).
DRA Outbound Objects Filtered/sec The number of objects (per second) acknowledged
by outbound replication partners that required no updates. This
counter includes
objects that the outbound partner did not already have.
DRA Outbound Objects/sec The number of objects sent (per second) though outbound
replication to replication partners.
DRA Outbound Properties/sec The number of properties sent per second. This
counter
tells you whether a source server is returning objects or not. Sometimes, the
server might stop working correctly and not return objects quickly or at all.
DRA Outbound Values (DNs only)/sec The number
values of object properties sent (per
second), to replication partners in which the values are
for object properties that
belong to distinguished names. Values
for distinguished names, such as group or
distribution list memberships, are more expensive to apply than other kinds of
values because a group or distribution list
object can include hundreds or
thousands of members. In contrast, a simple object might have only one or two
attributes.
DRA Outbound Values Total/sec The total number of
values of object properties sent
(per second), to replication partners.
DRA Remaining Replication Updates The number of changes to objects that have been
received in the current directory replication update packet
for the DRA that have
not yet been applied to the local server. A sharp decline in the rate at which
objects are applied to the database indicates normal operation, while a gradual
decline indicates that complex objects are being applied. This
counter is a helpful
gauge of whether a server is slow to replicate.
DRA Pending Replication Synchronizations The number of directory synchronizations
that are queued for this server that are not yet processed. This
counter helps in
determining replication backlog - the larger the number, the larger the backlog.
DRA Sync Requests Made The number of synchronization requests made to replication
partners since computer was last restarted.
DS Security Descriptor Suboperations/sec The number of suboperations (per second)
of security descriptor propagation. One operation of security descriptor
propagation comprises many suboperations. There is approximately one suboperation
for each object that the propagation operation causes the propagator to examine.
DS Security Descriptor Propagation Events The number of events of Security
Descriptor Propagation that are queued but not yet processed.
DS Threads in Use The current number of threads in use by the directory service
(different from the number of threads in the directory service process). This
counter represents the number of threads currently servicing API calls by clients,
and you can use it to determine whether additional CPUs would be beneficial.
LDAP Client Sessions The number of sessions of connected LDAP clients.
LDAP Bind Time The time (in milliseconds) required for the completion of the last
successful LDAP binding.
Kerberos Authentications/sec The number of times per second that clients use a
client ticket to this domain controller to authenticate to this domain
controller.
NTLM Authentications/sec The number of NTLM authentications (per second) serviced
by this domain controller.
LDAP Successful Binds/sec The number LDAP bindings (per second) that occurred
successfully.
LDAP Searches/sec The number of search operations per second performed by LDAP
clients.

FileReplicaConn Performance statistics
for the Replicaconn object that defines
replica connections to Dfs roots.
FileReplicaSet Performance statistics
for the Replicaset object that defines a
replica set.Cristian Neira
