The objective of this document is to assist you in the supervision of your Exchange 2013 architecture.

Exchange 2013 Architecture, Concepts and Components

Exchange Server 2013 consists of two basic building blocks. Each provides a high availability and fault-tolerant unit that are decoupled from each other.

DAGDatabase Availability Group (DAG): The Database Availability Group (DAG)

CAS: the client access servers make up the CAS group (Client Access Server).

ServiceNav provides you with a set of service models to monitor your entire Exchange 2013 architecture.

Configuration

General

It is recommended that you put all the servers composing your Exchange 2013 architecture under supervision.

For all physical or virtual servers, depending on the operating system, apply the following equipment :

  • Windows 2008 system: This model is intended for Windows 2008 servers. It allows to know if the equipment is UP or DOWN and also performs analysis to know the CPU, RAM, SWAP, and disk I/O usage. Use the census to supervise disk partitions and network interfaces.
  • Windows 2012 system: This model is intended for Windows 2012 servers. It allows to know if the equipment is UP or DOWN and also performs analysis to know the CPU, RAM, SWAP, and disk I/O usage. Use the scan to monitor disk partitions and network interfaces.
  • Windows 2016 system: This model is intended for Windows 2016 servers. It allows to know if the equipment is UP or DOWN and also performs analysis to know the CPU, RAM, SWAP, and disk I/O usage. Use the scan to monitor disk partitions and network interfaces.

CAS (Client Acces Server)

Monitor virtual IP or VIP connectivity

On CAS servers, depending on the architecture deployed, apply the following templates :

  • HTTP/HTTPS : HTTP/HTTPS: tests an HTTP/HTTPS request, to be used to monitor the URL of the virtual IP
  • TCP-Port : tests if the TCP port indicated in configuration is open, and collects the connection delay, to be used to monitor the following ports:
    • IMAP4 clients (143-993)
    • POP3 clients (110-995)
    • SMTP authenticated clients (587)
    • SMTP (25)
    • HTTP (80)
    • Front End Transportation Service (717)

Exchange Services on Exchange 2013 Client Access Servers

On CAS servers, monitor the startup of services grouped by impact BLOCKING or DEGRADING via the service model MS-WIN-ServicesList-Started:

Services with impact BLOCKING:

  • MSExchangeADTopology
  • MSExchangeDiagnostics
  • MSExchangeFrontEndTransport
  • MSExchangeServiceHost

Services with impact DEGRADING:

  • MSExchangeHM
  • MSExchangeIMAP4
  • MSExchangePOP3
  • HostControllerService
  • MSExchangeUMCR

Monitor Exchange performance on Exchange 2013 Client access servers

On CAS servers, apply the following models - do not rely on naming, the models below are compatible with Exchange 2013 :

  • MS-EXCHANGE2013-TAIL-LENGTHIndicates the length of a queue, expressed as the number of messages.
  • MS-EXCHANGE2007_2010-ADAccess: Indicates the number of searches from Microsoft Exchange Server to the Active Directory out of time in the last minute.
  • MS-EXCHANGE2007-SMTP-MSGS-RECEIVED: Indicates the frequency of delivery of SMTP messages to the transport server, expressed in messages per second.
  • MS-EXCHANGE2007-SMTP-MSGS-SENT: : Specifies how often SMTP messages are sent from the transport, expressed in messages per second.
  • MS-Exchange-Certificate-Expiration: Calculates the number of days remaining before the expiry date of the Exchange certificate. If more than one certificate, calculates the number of days remaining before the expiration date of each certificate and alerts if for at least one certificate the threshold is exceeded.

Edge Transport

Exchange Services on Transport Edge Exchange 2013 Servers

On the servers of Transport Edge, monitoring the start-up of services grouped by impact BLOCKING or DEGRADING via the service model MS-WIN-ServicesList-Started:

Services with impact BLOCKING:

  • ADAM_MSExchange
  • MSExchangeDiagnostics

Services with impact DEGRADING:

  • MSExchangeAntispamUpdate
  • MSExchangeEdgeCredential
  • MSExchangeHM
  • MSExchangeServiceHost
  • MSExchangeTransport
  • MSExchangeTransportLogSearch

DAG (Database Availability Group)

Monitor connectivity to mailbox (MBX) 

On MBX servers, depending on the architecture deployed, apply the following model :

  • TCP-Port: Tests if the TCP port indicated in configuration is open, and collects the connection delay, to be used to monitor the next port:
    • HTTP (80)

Exchange services on Exchange 2013 mailbox servers

On MBX servers, monitor the startup of services grouped by impact BLOCKING or DEGRADING via the service model MS-WIN-ServicesList-Started :

Services with impact BLOCKING:

  • MSExchangeADTopology
  • MSExchangeDagMgmt
  • MSExchangeDiagnostics
  • MSExchangeMailboxReplication
  • MSExchangeDelivery
  • MSExchangeSubmission
  • MSExchangeRepl
  • MSExchangeRPC
  • MSExchangeFastSearch
  • HostControllerService
  • MSExchangeServiceHost
  • MSExchangeThrottling

Services with impact DEGRADING:

  • MSExchangeAntispamUpdate
  • MSExchangeEdgeSync
  • MSExchangeIMAP4BE
  • MSExchangeMailboxAssistants
  • MSExchangePOP3BE
  • WSBExchange
  • MSExchangeTransport
  • MSExchangeTransportLogSearch
  • MSExchangeUM

Monitor the size of Exchange databases and mailboxes

On MBX servers, apply the following templates :

  • MS-EXCHANGE-MailboxDatabaseStatusPS: monitors the size of an Exchange database and notifies when thresholds are exceeded.
  • MS-EXCHANGE-MailboxStatusPS: returns the status of the mailbox quota on an Exchange server.

Monitor the DAG replication

On MBX servers, apply the following template:

  • MS-Exchange-DAG-Replication-Status: verifies all aspects of replication and replay for a mail server within a Database Availability Group (DAG). Alerts in case of problems or replication failures.

Monitor Exchange performance on the servers of Exchange 2013 mailboxes

On MBX servers, apply the following models - do not rely on naming, the models below are compatible with Exchange 2013 :

  • MS-EXCHANGE2007-MSGS-RECEIVED-BY-MS: Indicates the frequency of message delivery to the storage bank, expressed in messages per second.
  • MS-EXCHANGE2007-MSGS-SENT-TO-T: Indicates how often messages are sent to the transport server, expressed in messages per second.

Active Directory

Monitor access to the Active Directory

On AD servers, apply the following template:

  • MS-Active_Directory: Test a connection to an Active directory, notifies if the test fails.
  • DNS-internal: Tests a DNS query internally and notifies if the test fails.
  • DNS-externe: Tests an external DNS query.
