2.2.10.2.14 DNSSRV_DS_STATS

The DNSSRV_DS_STATS structure has DNS server statistics related to directory server processing. The UpdateLists member through DsWriteType member refer to statistical values, when the server is propagating changes from the in-memory database to the directory server.

This structure MUST be formatted as follows:

Header (8 bytes): A structure of type DNSSRV_STAT_HEADER (section 2.2.10.2.1).

DsTotalNodesRead (4 bytes): The total number of DNS nodes read from the directory server.

DsTotalRecordsRead (4 bytes): The total number of resource records read from the directory server.

DsNodesLoaded (4 bytes): The number of valid DNS nodes found in the directory server and loaded in memory by the server.

DsRecordsLoaded (4 bytes): The number of resource records loaded in memory by the server.

DsTombstonesRead (4 bytes): The number of nodes read from the directory server and found in a tombstoned state.

DsUpdateSearches (4 bytes): The number of zone update searches performed on the directory server.

DsUpdateNodesRead (4 bytes): The number of DNS nodes that were read from the directory server and contained updated information.

DsUpdateRecordsRead (4 bytes): The number of resource records that were read from the directory server and contained updated information.

UpdateLists (4 bytes): The number of in-memory nodes with an updated list of record.

UpdateNodes (4 bytes): The number of in-memory nodes that required an update in the directory server.

UpdateSuppressed (4 bytes): The number of in-memory nodes that did not require any write to the directory server.

UpdateWrites (4 bytes): The number of in-memory nodes that required writing to the directory server.

UpdateTombstones (4 bytes): The number of in-memory nodes that required tombstoning.

UpdateRecordChange (4 bytes): The number of in-memory nodes that required record changes.

UpdateAgingRefresh (4 bytes): The number of in-memory nodes that required an aging information refresh.

UpdateAgingOn (4 bytes): The number of in-memory nodes that required aging to be enabled.

UpdateAgingOff (4 bytes): The number of in-memory nodes that required aging to be disabled.

UpdatePacket (4 bytes): The number of in-memory nodes modified as a result of update packets being received.

UpdatePacketPrecon (4 bytes): The number of in-memory nodes modified as a result of update packets being received with prerequisites (as discussed in [RFC2136] section 2.4).

UpdateAdmin (4 bytes): The number of in-memory nodes modified as a result of administrator initiated changes.

UpdateAutoConfig (4 bytes): The number of in-memory nodes modified as a result of an auto-configure operation.

UpdateScavenge (4 bytes): The number of in-memory nodes modified as a result of a scavenging cycle.

DsNodesAdded (4 bytes): The number of new nodes added to the directory server.

DsNodesModified (4 bytes): The number of nodes modified in the directory server.

DsNodesTombstoned (4 bytes): The number of nodes tombstoned in the directory server.

DsNodesDeleted (4 bytes): The number of nodes deleted from the directory server.

DsRecordsAdded (4 bytes): The number of records added to the directory server.

DsRecordsReplaced (4 bytes): The number of records modified or replaced in the directory server.

DsWriteSuppressed (4 bytes): The number of records added to the directory server.

DsSerialWrites (4 bytes): The number of records that had matching data and hence were not written to the directory server.

LdapTimedWrites (4 bytes): The number of times the server performed a timed LDAP write operation.

LdapWriteTimeTotal (4 bytes): The cumulative time, in milliseconds, consumed by server-performed timed LDAP write operations.

LdapWriteAverage (4 bytes): The average time, in milliseconds, for all server performed timed LDAP write operations since the server was last restarted.

LdapWriteMax (4 bytes): The longest duration taken, in milliseconds, for any single server-performed timed LDAP write-operation.

LdapWriteBucket0 (4 bytes): The number of LDAP write-operations that took less than 10 milliseconds.

LdapWriteBucket1 (4 bytes): The number of LDAP write-operations that took between 10 and 100 milliseconds.

LdapWriteBucket2 (4 bytes): The number of LDAP write-operations that took between 100 milliseconds and 1 second.

LdapWriteBucket3 (4 bytes): The number of LDAP write-operations that took between 1 and 10 seconds.

LdapWriteBucket4 (4 bytes): The number of LDAP write-operations that took between 10 and 100 seconds.

LdapWriteBucket5 (4 bytes): The number of LDAP write-operations that took more than 100 seconds.

LdapSearchTime (4 bytes): The cumulative time, in milliseconds, consumed by server-performed LDAP searches.

FailedDeleteDsEntries (4 bytes): The number of times the server failed to delete entries from the directory server.

FailedReadRecords (4 bytes): The number of times the server failed to read records from the directory server.

FailedLdapModify (4 bytes): The number of times the server failed to modify records in the directory server.

FailedLdapAdd (4 bytes): The number of times the server failed to add entries to the directory server.

PollingPassesWithDsErrors (4 bytes): The number of times the server hit failure while polling zones in the directory server. This field SHOULD<75> be present. A client can tell whether the field is present based on the size of the buffer holding this structure.

LdapReconnects (4 bytes): The number of times the server attempted to reconnect to the directory server. This field MUST be present if and only if PollingPassesWithDsErrors is present. A client can tell whether the field is present based on the size of the buffer holding this structure.

DsWriteType (160 bytes): An array of 32-bit unsigned integers that keeps track of update requests for different DNS record types as specified DNS_RECORD_TYPE (section 2.2.2.1.1). There are a total of 40 entries each corresponding to the number of received update requests for different record types in the order specified in DNS_RECORD_TYPE (section 2.2.2.1.1), starting from DNS_TYPE_ZERO to DNS_TYPE_DNAME.
