Maintenance & Monitoring Exchange Environment

Tzahi KolberIT Supervisor - Polycom Israel


What will we cover
What will we cover:

  • Exchange Maintenance types.

  • Exchange Frequent Maintenance.

  • Exchange Server 2003 Monitoring.

  • Exchange Server 2007 Monitoring & Reporting.


Problems and Concerns

  • Maintenance:

    • Keep server running with the minimum of downtime (do it as faster as possible).

    • Maintain the server for getting the best performance ALL the time.

    • Prevent security issues that can harm the / crash the server (WU / AV, open ports etc).

    • Different maintenance plan to different intervals (Daily / Weekly / Monthly…).

    • DRP / Backups / Network load?

  • Monitoring:

    • Dynamically change the monitoring parameters VS. the server changes (HW / Performance / etc).

    • Use different ways for alert (email / SMS / Monitor).



Exchange maintenance types
Exchange maintenance types

  • Online Maintenance.

  • Manual maintenance base on frequent time frame (including security maintenance for the OS and Apps).

  • DRP / Backups / Network.


Online Maintenance

  • Not clash with backup schedules

  • Database size (what recommended VS. what can be done).

  • Purge Indices (public and mailbox stores)

  • Tombstone Maintenance (public and mailbox stores)

  • Dumpster Cleanup (public and mailbox stores)

  • Cleanup Deleted Mailboxes (mailbox stores)

  • Events for each Database processed

    • 700 Defrag Started

    • 701 Defrag Ended

    • 1221 The Defrag ended and the amount of free space in DB.


Eseutil switches
ESEUtil switches

  • /D = Defrag Mode

    • New signatures

    • Log files mismatch, immediate backup required

    • /T can be used to specify alternate location for the temp files

  • /M = Dump headers (/ML, /MK, /MH)

  • /R = Recovery performs soft recovery

  • /K = Integrity Check for Snapshots

  • /G = Checks Integrity at the ESE Level

    • No Changes Are Made, This is a reporting Tool

  • /F = Copy Mode

  • /C = Hard Recovery Mode (direct to restore.env)

    • /CC = Force Hard Recovery

    • /CM Dump the restore.env file header

  • /P = Repair

    • /P

      • /CreateSTM

    • When to perform a repair

    • /p  /d  “Isinteg –fix –test alltests”


Dumping file headers using eseutil
Dumping File Headers using ESEUtil

  • Database Header

    • Database signature, log signature

    • State: Consistent or Inconsistent

  • Checkpoint Header

    • Shows checkpoint log file and signature

  • Transaction Log File Headers

    • Generation number

    • Log file signature

    • The attached databases


Offline defrag yes no
Offline Defrag – Yes / No ???

  • What should I consider before offline defrag?

    - Backup, Backup, Backup – ALL three !!!

  • How frequent should I defrag the DB:

    - Depends on 1221 event and disk space that you have.

  • What options do I have?

    - Most common: eseutil /d priv1.edb /te:\tempedb.edb (e - is the alternet location).

  • What should I consider after offline defrag?

    - Backup, Backup, Backup – ALL three !!!

    Main reason – signature changes.


Exchange daily weekly maintenance
Exchange Daily / Weekly maintenance

  • Examine the Windows Event Logs for Exchange warnings and errors.

  • Check Backup Jobs.

  • Check Performance Monitors / task manager.

  • Check disk usage / connectors status.

  • Check Security (AV / WU / etc) Updates.

Email chain monthly maintenance
Email chainMonthly maintenance

  • Security Checks (penetration tests).

  • Capacity Planning (mailboxes / HW load, Network).

  • Disaster Recovery Tests (Backup / Restore, including AD).

  • Document changes in the email chain (components, HW, drive letters, etc).

Drp backups network
DRP / Backups / Network.

  • Check options for DRP compatibilities:

    Storage (snapshots), Geo Cluster, Cluster, Dual NIC, Mirror disks, LCR, CCR.

  • Check backups by restoring DB to RSG, save tapes in off site, check backups logs.

  • Keep documents of the mail flow & Exchange configuration.

  • Keep printed procedures in case of DR.

  • Check Network performance, updated driver’s NICs, use VLANs if possible.
