Active Directory monitoring with Site24x7.

Get insights on Microsoft Active Directory (AD) performance including active client sessions of LDAP and SAM, replication traffic, database instances, domain services and more.

Monitor the performance of domain controllers with a complete AD health check.

AD monitoring lets you to diagnose performance issues of domain services (DS) and obtain information on DS read, DS write and DS search operations.

Get the percentage of directory reads, writes and searches from:

  • Directory and Resource Administration (DRA)
  • Name Service Provider Interface (NSPI)
  • New Technology Directory Service API (NTDSAPI)
  • Local Security Authority (LSA)
  • Kerberos Authentications/sec
  • NTLM Authentications/sec
 Active Directory Domain Services

Prevent failure of replication issues by monitoring AD performance.

Access to folders and files becomes difficult for users when there is a failure of replication services. AD performance monitoring helps to alleviate these issues by gaining information on directory and resource administration (DRA) services including:

  • Replication status
  • DRA Pending Replication Synchronizations
  • DRA Pending Replication Operations
 Active Directory Replication issues

Perform an Active Directory health check and track SAM and LDAP client sessions.

Knowing the AD health status helps to prevent server overload by knowing the number of clients connected to a specific Lightweight Directory Access Protocol (LDAP) session. Also, get the percentage of directory writes and searches from LDAP sessions.

Active Directory performance monitoring also informs about the Security Account Manager (SAM) client sessions. SAM intimates other services that their subsystem is ready to accept requests.

Active Directory LDAP sessions

Ensure consistent performance of Active Directory databases.

Monitoring Active Directory databases ensures consistent functioning of directory files and there is enough room for the files to grow. Get additional inputs on:

  • The rate of completed database read/write operations
  • System memory used by the database cache manager
  • The threads waiting for their data to be written to a log

Network monitoring licensing is purely based on the number of interfaces that are monitored. It is mandatory to have at least one active interface in order to monitor a device. While ten performance counters per device can be monitored for free, every additional ten is counted as one interface.

Premium support includes email, community, chat and phone.

Every webpage that is loaded in the browser is considered as a page view, irrespective of the number of resources that are loaded behind. For example, for a single page to load, there are various resource calls for images, css, etc, which are not counted in page views. Only the webpage that the user visits is counted as page views.

Credits are auto-refilled every month, however left over refilled credits are not carried forward to the next month.
